Dermaplaning: What It Actually Does, the Hair-Growth Myth, and Whether It's Worth It

Search for skin-smoothing treatments online, and you will quickly encounter dermaplaning. Also known as dermablading or professional face shaving for women, this physical exfoliation procedure has transitioned from a clinical secret used to prep patients for chemical peels to a mainstream beauty trend. Promised to deliver instantly smooth, radiant skin, a flawless makeup application, and better penetration of skincare products, it is offered at almost every medical spa and dermatology clinic.

Despite its popularity, dermaplaning is surrounded by one of the most persistent myths in personal care: Does shaving your face make your hair grow back thicker, darker, or faster?

For many consumers, the fear of developing coarse, dark stubble on their cheeks or upper lip is enough to keep them away from the treatment. Other patients wonder if they can save money by purchasing a pack of plastic dermaplaning razors and performing the treatment themselves at home, or if the risk of cuts, infections, and skin barrier damage makes an in-office treatment worth the extra cost.

To help you separate clinical fact from marketing fiction, this guide reviews the biology and dermatology behind dermaplaning. We analyze the mechanical exfoliation process, debunk the vellus-hair regrowth myth with clinical safety guidelines, explain how dermaplaning acts as a primer for chemical peels, compare it to other resurfacing modalities, contrast at-home and in-office techniques, and detail the safety guidelines you must follow to protect your skin barrier.

What is dermaplaning and how does it work?

Dermaplaning is a form of physical mechanical exfoliation. During an in-office treatment, a licensed aesthetician or dermatologist uses a sterile, medical-grade surgical scalpel—typically a #10 or #14 carbon steel or stainless steel blade—attached to a metal handle.

The provider holds the skin taut with one hand and sweeps the blade across the dry skin at a 45-degree angle using short, light strokes in the direction of hair growth. This scraping motion physically removes two distinct components from the face:

1. The Stratum Corneum: The outermost layer of the epidermis, consisting of dead, flattened skin cells (corneocytes). In normal skin, corneocytes naturally shed through a process called desquamation. However, as the skin ages or is exposed to environmental stress, desquamation slows down, leading to an accumulation of dead cells. This buildup scatters light, making the complexion appear dull, dry, and textured.
2. Vellus Hair: Commonly referred to as "peach fuzz." This is the fine, short, non-pigmented hair that covers the majority of the face. Unlike coarse scalp or beard hair, vellus hair lacks a central medulla, which is why it is soft and virtually translucent. However, vellus hair can trap light, sweat, oil, and makeup, contributing to a dull skin tone and a textured, uneven foundation finish.

How Dermaplaning Differs from Wet Shaving

While both dermaplaning and shaving use a blade to cut hair, they are clinically distinct. Wet shaving is typically performed on wet skin lubricated by shaving cream or soap, using multi-blade cartridge razors. The primary goal of shaving is simply to cut hair at the surface.

Dermaplaning is performed on completely dry, clean skin with a single, ultra-sharp surgical blade. The lack of lubrication increases friction, allowing the blade to scrape off the accumulated dead stratum corneum cells alongside the vellus hair. Dermaplaning is as much an exfoliation treatment as it is a hair removal method, whereas shaving is almost exclusively hair removal.

Does dermaplaning make hair grow back thicker or darker?

To address the most common concern: No, dermaplaning does not make your hair grow back thicker, darker, coarser, or faster. This is a physiological impossibility, and the claim has been repeatedly debunked by dermatologists and clinical consensus guidelines.

The Biology of Hair Growth

To understand why this myth is false, we must look at the anatomy of the hair follicle. Hair growth is controlled by the hair bulb, which is located deep within the dermis (the second layer of the skin).

The follicle is supplied by blood vessels and is regulated by genetics, systemic hormones (specifically androgens like testosterone), and age. The hair shaft that sits on the surface of the skin is composed of dead, keratinized cells.

When you dermaplane or shave, the scalpel cuts the hair shaft at the surface of the skin. The blade does not touch the follicle, modify your DNA, or influence your hormone levels. Because the biological control center of the hair remains untouched, it is impossible for the blade to alter the density, thickness, growth rate, or color of the hair.

The Source of the Myth: The "Blunt Tip" Illusion

If the biology is clear, why does this myth persist? The answer lies in how a hair shaft grows and how it is cut:

• Natural Hair: A natural, uncut vellus hair has a tapered end, meaning it is thicker at the base (near the skin) and thinnest at the tip. Because the tip is fine and flexible, it feels soft to the touch.
• Cut Hair: When a blade cuts the hair shaft, it cuts it at an angle, leaving a flat, blunt end. As the hair continues to grow and emerges from the skin, this blunt, flat surface is what pushes past the pore.
• The Sensation: When you run your fingers over the newly emerging hair, the flat, blunt tips offer mechanical resistance, making the hair feel stiff, prickly, or coarser than it did before.
• The Appearance: The flat surface of the cut hair shaft also reflects light differently than a tapered tip, which can make the regrowth appear slightly darker under direct lighting.

However, once the hair grows out to its full length, the tip will naturally taper again, and it will return to its original soft, translucent state.

Clinical Guidelines and Expert Consensus

This biological reality is recognized in clinical safety protocols worldwide. For example, the Safety Guidelines for Chemical Peel Procedures published by L'Oréal Dermatological Beauty and SkinCeuticals explicitly states:

"Exfoliation of the skin including Dermaplaning does not promote new hair growth, nor does it promote denser or darker hair growth; the guideline notes the hair is left blunt-ended and the root undisturbed."

This position is corroborated by clinical databases at academic medical centers such as the Cleveland Clinic and WebMD, which confirm that physical dermabrasion and blade-based dermaplaning have zero impact on the follicular growth cycle of vellus hair.

The Synergy: Dermaplaning and Chemical Peels ("Micropeels")

In professional dermatology and aesthetic clinics, dermaplaning is rarely performed as a standalone treatment. Instead, it is frequently used as a preparatory step before a chemical peel—a combination procedure clinically referred to as a "micropeel."

Pre-Peel Priming Mechanism

The stratum corneum is the skin's primary barrier. It is composed of dense layers of dead cells embedded in a lipid matrix, designed to keep moisture in and environmental agents out. While this barrier is vital for health, it also limits the penetration of topically applied therapeutic agents.

When a provider performs dermaplaning before a chemical peel, they physically scrape away this outer barrier. This has a profound synergistic effect on the subsequent acid application:

1. Potentiates Penetration: With the stratum corneum removed, the chemical peel solution (typically glycolic acid, lactic acid, or salicylic acid) can penetrate the viable layers of the epidermis faster and more deeply.
2. Ensures Uniformity: In skin with irregular texture, chemical peels can pool in dry patches, leading to uneven penetration and localized hot spots (areas of excessive irritation or chemical burns). Scraping the skin smooth ensures that the peel solution distributes evenly across the entire face.
3. Enhances Clinical Efficacy: Peer-reviewed literature on chemical peel techniques, such as a practical review published in the National Institutes of Health's PubMed Central (PMC6122508), documents that combining mechanical dermaplaning with chemical peeling produces superior results in treating photodamage, fine lines, and superficial hyperpigmentation compared to using either modality alone. (Our chemical peels for dark skin guide covers how that pairing is adjusted for Fitzpatrick IV–VI skin.)

Chemical Peel Penetration Comparison

[STANDALONE CHEMICAL PEEL]
  Acid Solution ──► [Stratum Corneum (Thick Barrier)] ──► Slow, uneven penetration to epidermis

[MICROPEEL (Dermaplaning + Chemical Peel)]
  Dermaplaning  ──► Removes Stratum Corneum
  Acid Solution ──► [Viable Epidermis] ────────────────► Rapid, deep, uniform penetration

The Safety Caveat for Providers and Patients

While this synergy improves clinical results, it also increases the risk of side effects. Because the skin’s natural defense barrier is gone, the chemical peel will feel significantly more intense.

Patients will experience a higher level of self-reported burning, stinging, and erythema (redness). The provider must monitor the peel closely, use lower concentrations or shorter contact times than they would on un-dermaplaned skin, and neutralize the acid promptly to prevent epidermal damage.

Dermaplaning vs. Microdermabrasion vs. Shaving

To choose the right exfoliation method, patients must understand how dermaplaning compares to microdermabrasion and standard home shaving.

1. Microdermabrasion

Microdermabrasion is a device-driven mechanical exfoliation method that uses a motorized wand to spray abrasive micro-crystals onto the skin or uses a diamond-grit tip to abrade the surface under vacuum suction.

• Vellus Hair: Microdermabrasion does not remove vellus hair. The abrasive tip is designed to sand the skin surface, but it cannot cut hair. In fact, vacuuming over hair can cause follicle irritation and folliculitis.
• Skin of Color Safety: Microdermabrasion carries a higher friction coefficient, which can trigger inflammatory responses. For patients with Fitzpatrick IV-VI skin types, this friction can cause post-inflammatory hyperpigmentation (PIH). Dermaplaning, which uses a single clean sweep of a blade with minimal lateral friction, is generally considered safer for skin of color.

2. Home Shaving

• The Tool: Shaving utilizes standard safety razors designed for body hair. These razors have multiple blades set in a plastic cartridge, often surrounded by moisturizing strips.
• Exfoliation: Because safety razors are designed to slide over the skin with minimal resistance, they do very little to exfoliate the stratum corneum.
• Risk: Shaving is performed on wet skin, often in the shower, where the environment is humid and prone to bacterial growth. Reusing a multi-blade razor that has been sitting in a damp bathroom introduces a high risk of bacterial transfer, leading to razor bumps and pseudofolliculitis barbae.

At-Home vs. Professional (In-Office) Dermaplaning

The surge in popularity of dermaplaning has led to a flood of consumer products designed for home use. From cheap plastic "eyebrow shaper" razors to expensive motorized sonic dermaplaning wands, patients are increasingly performing the treatment themselves. However, the risk profiles of at-home and in-office treatments are very different.

In-Office Dermaplaning (The Clinical Standard)

• The Blade: Performed using a sterile, single-use, surgical-grade scalpel. These blades are incredibly sharp and are designed to cut cleanly through keratinized tissue without pulling the skin.
• Technique: The provider is trained to hold the skin taut in multiple directions. This skin tension is critical: it prevents the blade from catching on skin folds or sagging tissue, which would cause nicks and cuts.
• Exfoliation Level: Because of the blade's sharpness and the provider's training, professional dermaplaning achieves a uniform, deep exfoliation of the stratum corneum.

At-Home Dermaplaning (The Consumer Alternative)

• The Blade: Consumer dermaplaning tools are designed with safety in mind, meaning they are significantly duller than surgical scalpels and are wrapped in plastic safety guards.
• The Outcome: Because the blade is dull, it is highly effective at cutting fine vellus hair, but it provides very little physical exfoliation. It behaves more like a face razor than a dermaplaning scalpel.
• The Risks:
  1. Barrier Damage and Nicks: To compensate for a dull blade, consumers often apply excessive pressure or run the blade over the same area multiple times. This causes scraping irritation, micro-tears, and skin barrier disruption.
  2. Infection: Consumers frequently reuse disposable blades. A blade that has been used once has accumulated microscopic skin cells, sebum, and bacteria. Storing it in a bathroom and using it again can introduce bacteria into micro-tears, resulting in painful pustules and folliculitis.
  3. Acne Spread: Without clinical training, consumers often slide the blade directly over active pimples, popping the lesions and spreading bacteria across the face.

Safe At-Home Protocol

If you choose to dermaplane at home, you must follow a strict safety protocol:

1. Sanitize: Wash your face thoroughly and dry it completely. Clean the blade with rubbing alcohol before starting.
2. Never Reuse: Treat every home razor as a single-use tool. Throw it away after one use.
3. Hold Taut: Use your non-dominant hand to pull your skin tight.
4. Use Light Pressure: Hold the blade at a 45-degree angle and slide it down the face using very light pressure. Never push the blade into the skin.
5. Avoid active breakouts entirely.

Who should NOT dermaplane? Contraindications and Aftercare

While dermaplaning is safe for most skin types, there are specific clinical scenarios where the treatment can cause harm.

Absolute Contraindications

You should not receive a dermaplaning treatment if you have:

• Active Inflammatory Acne: Scraping a blade over active pustules, papules, or cysts will slice the lesions open. This spreads Cutibacterium acnes bacteria across the face, leading to widespread infection and increasing the risk of permanent scarring and post-inflammatory hyperpigmentation.
• Active Rosacea Flares: Patients with rosacea have highly sensitive, reactive skin. The mechanical scraping can trigger severe flushing, worsen telangiectasia (broken capillaries), and cause inflammation.
• Active Herpes Simplex (Cold Sores): Dermaplaning over a cold sore can spread the HSV-1 virus across the face, causing a widespread outbreak (herpetic eczema).
• Recent Isotretinoin Use: If you have taken oral isotretinoin (Accutane) within the past 6 months, your skin's healing capacity is compromised, and the risk of scarring from physical dermabrasion is elevated — our isotretinoin aesthetic-procedure waiting period guide explains the evidence behind that window.
• Sunburn or Open Wounds.

Skincare Adjustments: Actives Scheduling

To prevent over-exfoliation and barrier damage, you must adjust your skincare routine before and after a dermaplaning treatment:

• Before the Treatment (3–5 Days): Stop using all prescription retinoids (tretinoin, Tazorac) and over-the-counter retinol, as well as chemical exfoliants (glycolic acid, salicylic acid, lactic acid). This allows the skin barrier to stabilize so the blade does not scrape too deeply. (Not sure which retinoid you're on? Our retinol vs. tretinoin guide breaks down the differences.)
• After the Treatment (48–72 Hours): Your skin barrier has been stripped of its outer protective layer. Avoid all retinoids, chemical exfoliants, and harsh scrubs for at least 3 days. Focus on hydration and barrier repair by using products containing ceramides, hyaluronic acid, and centella asiatica.
• Sunscreen (Mandatory): freshly exfoliated skin is highly vulnerable to ultraviolet (UV) radiation. Exposure to sun without protection post-dermaplaning can lead to rapid hyperpigmentation and sun damage. You must apply a broad-spectrum, mineral-based sunscreen (SPF 30 or higher) daily.

FAQs

Does dermaplaning make hair grow back thicker?

No, dermaplaning does not make hair grow back thicker, darker, or coarser. This is a biological myth. The blade only cuts the dead hair shaft at the surface of the skin. It does not affect the hair follicle deep within the dermis, which is what controls hair diameter, color, and growth cycle. The myth persists because the cut hair emerges with a flat, blunt tip that feels prickly or stiff initially, but its diameter and color remain unchanged.

How often should you dermaplane?

In-office dermaplaning is typically performed once every 3 to 4 weeks. This frequency aligns with the skin’s natural cellular renewal cycle (approximately 30 days). Dermaplaning more frequently than every 3 weeks can over-exfoliate the skin, stripping the barrier before it has had time to regenerate, leading to chronic redness, dryness, and sensitivity.

Can you dermaplane while using retinol or tretinoin?

Yes, but you must adjust your schedule. You must stop using retinol or tretinoin 3 to 5 days before your dermaplaning session. Because retinoids speed up cell turnover, they thin the outer stratum corneum. Dermaplaning on retinoid-sensitized skin can scrape too deeply, causing raw patches and chemical sensitivity. You can resume your retinoid 48 hours after the treatment, once your skin barrier has re-stabilized.

Is dermaplaning safe during pregnancy?

Yes, dermaplaning is completely safe during pregnancy. Because it is a physical exfoliation method that does not involve the absorption of chemical acids or drugs, it carries zero systemic risk. It is a popular alternative to chemical peels (which often contain salicylic acid, contraindicated during pregnancy) for pregnant women who want to address pregnancy-related skin dullness or texture changes.

Why do I break out after dermaplaning?

Breaking out after a dermaplaning treatment is typically caused by one of three issues:

1. Dull or Reused Blades: If you dermaplane at home and reuse a blade, you are introducing accumulated bacteria into micro-nicks in the skin, causing folliculitis.
2. Popping Pimples: If the blade was run over active, non-visible congestion, it may have spread bacteria across the face.
3. Active Product Sensitivity: Freshly dermaplaned skin has a stripped barrier, making it highly absorbent. If you apply heavy, oil-based makeup, thick pore-clogging moisturizers, or irritating active serums immediately after the treatment, they will penetrate deeply and clog pores, resulting in breakouts.

Is dermaplaning safe for dark skin or skin of color?

Yes, dermaplaning is highly safe and often preferred for individuals with darker skin types (Fitzpatrick skin phototypes IV through VI). Unlike mechanical resurfacing methods such as microdermabrasion or certain laser treatments, dermaplaning does not generate friction-induced heat or severe dermal inflammation. Heat and friction can trigger melanocytes to overproduce pigment in darker skin, leading to post-inflammatory hyperpigmentation (PIH). Because dermaplaning uses a single, clean sweep of a surgical blade with minimal lateral friction, it provides effective exfoliation without activating this inflammatory pigment cascade. However, the provider must be careful not to nick or cut the skin, as any physical cut can heal with hyperpigmentation in melanin-rich skin.

What should you apply to your skin immediately after dermaplaning?

Immediately after dermaplaning, the goal is to calm the skin, rehydrate the freshly exposed epidermal layers, and support the recovery of the skin barrier.

• Do apply: A hydrating, non-comedogenic serum containing low-molecular-weight hyaluronic acid, glycerin, or panthenol (Vitamin B5) to draw water into the skin. Follow this with a barrier-repairing moisturizer containing ceramides, squalane, or colloidal oatmeal to lock in moisture and seal the barrier.
• Do NOT apply: Avoid all exfoliating acids (glycolic, lactic, salicylic), vitamin C (L-ascorbic acid, which can sting and cause irritation on a raw barrier), retinoids, benzoyl peroxide, and heavy clay masks for at least 48 to 72 hours. You should also avoid applying heavy, oil-based makeup immediately after the procedure, as the pores are freshly cleared and highly susceptible to clogging.
