The Dermabrasion Deep Dive: What It Is, How It Works, and Who It’s For

What Is Dermabrasion? A Clear Answer Before We Dive In

Dermabrasion is a surgical skin resurfacing procedure that uses a high-speed rotating tool to sand away the top layers of skin, allowing smoother, renewed skin to grow back in its place.

Quick facts:

What it treats: Acne scars, surgical scars, fine wrinkles, sun damage, age spots, rhinophyma, and precancerous skin patches
Who performs it: A dermatologist or plastic surgeon — not an aesthetician
Anesthesia: Local anesthesia, sometimes with sedation
Recovery: 7–30 days for full healing; skin tone normalizes around 3 months
Average cost: $1,829 in the U.S. (not including anesthesia or facility fees)
Best candidates: Fair skin tones; deeper skin tones carry higher risk of pigmentation changes
Not the same as microdermabrasion: Dermabrasion goes much deeper and requires real downtime

If you’re weighing your options for skin resurfacing, it helps to understand exactly what this procedure involves — and whether it’s right for your skin type and goals.

I’m Dr. Thomas Jeneby, a board-certified plastic surgeon with over two decades of experience performing skin resurfacing procedures, including dermabrasion, at my accredited surgical center in San Antonio. In the sections below, I’ll walk you through everything you need to know — from how the procedure works to what recovery actually looks like.

Simple dermabrasion glossary:

Understanding the Mechanics of Dermabrasion

To understand how dermabrasion works, think of it as a highly controlled medical “sanding” of the skin. Unlike a scrub you might use at home, this is a surgical procedure designed to reach the deeper layers of the dermis to trigger a total regenerative response.

When we perform this at our San Antonio clinic, we use a motorized handpiece. This device holds an abrasive attachment—usually a diamond fraise (a stainless steel wheel coated in diamond dust) or a wire brush. These tools rotate at incredible speeds, typically between 12,000 and 15,000 RPM, though some specialized equipment can reach up to 85,000 RPM.

By carefully applying this rotating head to the skin, we remove the damaged outer layers. This “injury” is intentional; it forces the skin to repair itself by producing new Type I collagen and fresh epidermal cells. The result is a surface that is smoother, tighter, and more even in tone.

Dermabrasion vs. Microdermabrasion: Key Differences

It is very common for patients to confuse these two, but they are worlds apart in terms of intensity and results.

Depth of Injury: Microdermabrasion only “polishes” the stratum corneum (the very top layer of dead skin cells). Dermabrasion goes through the epidermis and into the papillary or mid-reticular dermis.
Invasiveness: Microdermabrasion is non-invasive and can be done by an aesthetician. Dermabrasion is a surgical procedure that must be performed by a board-certified surgeon or dermatologist.
Anesthesia: You don’t need numbing for microdermabrasion. For dermabrasion, we use local anesthesia, numbing sprays, or even IV sedation to ensure you are comfortable.
Recovery: Microdermabrasion has “zero downtime,” with skin recovering in 1–2 days. Dermabrasion requires a significant healing period, often 10–14 days for the new skin to form and up to 30 days for full initial healing.

The Evolution of Surgical Skin Planing

The history of dermabrasion is quite fascinating. While ancient Egyptians reportedly used sandpaper to smooth scars, modern mechanical dermabrasion was developed in the early 1950s. It was originally designed to treat the deep “pockmarks” left behind by acne and smallpox.

Over the decades, the precision of our tools has improved immensely. While laser technology has become more popular for general anti-aging, mechanical dermabrasion remains a “gold standard” for specific types of deep scarring because it allows the surgeon to feel the resistance of the scar tissue and adjust the depth with manual precision that a laser sometimes cannot match.

Ideal Candidates and Skin Conditions Treated

Who is the “perfect” candidate for this procedure? Generally, we look for individuals with specific structural skin concerns. According to comparative research, dermabrasion is exceptionally effective for:

Deep Acne Scars: Particularly “rolling” or “boxcar” scars that have sharp edges.
Rhinophyma: A condition, often associated with rosacea, that causes the skin on the nose to become thick, red, and bulbous.
Surgical or Traumatic Scars: We often use dermabrasion 6–10 weeks after a primary surgery to “blend” the scar into the surrounding skin.
Fine Lines: Specifically the deep “smoker’s lines” around the mouth.
Actinic Keratoses: Precancerous skin patches caused by sun damage.

Treating Deep Facial Irregularities with Dermabrasion

For many of our patients in Texas, the goal is to erase the reminders of teenage acne or childhood chicken pox. Dermabrasion is powerful because it softens the sharp “cliffs” of a scar. By sanding down the edges of a pockmark, the light no longer catches the indentation as harshly, making the skin look significantly smoother. Patients can realistically expect about a 50% improvement in the appearance of deep scars.

Contraindications and Safety Screening

Safety is our first priority at Find Your Beautiful. We may advise against dermabrasion if you have:

Darker Skin Tones: On the Fitzpatrick scale (a measure of skin pigment), types III through VI are at a much higher risk for “dyspigmentation”—meaning the treated skin might heal significantly lighter or darker than the surrounding area.
Active Infections: This includes active acne, herpes simplex (cold sores), or warts.
Recent Isotretinoin Use: If you have taken Accutane in the last 6–12 months, you must wait, as this medication changes how your skin heals and can lead to permanent scarring.
Keloid History: If your body tends to over-heal and create thick, raised scars, dermabrasion might trigger that response.

The Procedure: A Step-by-Step Guide

If we determine you are a good candidate, here is what a typical day looks like at our San Antonio facility.

Preparation: We start by thoroughly cleansing the skin with an antiseptic to prevent infection.
Marking: We mark the “anatomic units” (like the cheeks, chin, or forehead) to ensure even treatment and “feather” the edges so there isn’t a visible line where the treatment stops.
Anesthesia: We apply local anesthetic to numb the area. In many cases, we also use a “freezing spray” (cryogen) that firms the skin, making it easier to abrade accurately.
The Abrasion: Using the rotating handpiece, we gently move across the skin. We often have an assistant pull the skin taut to provide a smooth surface.
Protection: Once the desired depth is reached, we apply a thick layer of ointment and a dressing.

Pre-Procedure Protocols

Success starts weeks before the actual appointment. We often ask patients to:

Use Tretinoin: Applying a retinoid cream nightly for 2–3 weeks before the procedure can actually speed up the “re-epithelialization” (new skin growth) process.
Antiviral Medication: We prescribe antiviral prophylaxis to almost all patients to prevent a herpes outbreak, which can be triggered by the trauma of the procedure.
Stop Smoking: Smoking reduces blood flow to the skin and can significantly delay healing.
Review Medications: You’ll need to avoid aspirin and blood thinners for at least a week prior to minimize bleeding. For more on how we prepare for similar deep treatments, see our guide on what to expect and how to prepare.

Identifying Procedural Endpoints

How do we know when to stop? It’s all about the “endpoints.” As we move through the skin layers:

Papillary Dermis: We see “pinpoint bleeding.” This is usually the target for fine lines and light scarring.
Superficial Reticular Dermis: We see yellow, parallel collagen fibers and “confluent” (more steady) bleeding. This is the deepest safe limit. Going deeper than this significantly increases the risk of permanent scarring.

Recovery Timeline and Essential Aftercare

The first two weeks of recovery are the most critical. You are essentially managing a controlled “graze” over a large area of your face.

Days 1–3: The skin will be very red, swollen, and “weepy.” It may feel like a severe sunburn.
Days 7–10: This is when “re-epithelialization” typically finishes. The raw areas are covered by new, pink skin.
Weeks 2–4: Most people return to work by day 14. The skin will still be bright pink, but you can usually begin wearing hypoallergenic makeup.

Managing the First 72 Hours

Moisture is your best friend during this phase. We instruct our patients to:

Vinegar Soaks: Use a solution of 1 tablespoon of white vinegar in 1 pint of water. Soak clean gauze and apply it to the face for 10–15 minutes, 6 times a day. This keeps the area sterile and helps dissolve any crusting.
Occlusive Ointments: Immediately after the soak, apply a thick layer of petroleum jelly or a prescribed antibiotic ointment. The skin must never be allowed to get dry or form a hard scab.
Elevation: Sleep with your head elevated on 2–3 pillows for the first 3 weeks to keep swelling down.

Long-Term Healing and Sun Protection

Your new skin is “baby skin”—it is thin, sensitive, and lacks its usual UV protection.

Sun Avoidance: Stay out of the sun entirely for the first few weeks.
SPF 30+: Once the skin has closed, you must wear broad-spectrum sunscreen every single day for 6–12 months. Failure to do this can lead to permanent blotchiness or dark spots.
Activities: Avoid chlorinated pools for 4 weeks and “ball sports” or heavy exercise for 4–6 weeks to prevent accidental injury to the fragile tissue.

Risks, Costs, and Professional Alternatives

While dermabrasion is highly effective, it isn’t without risks. Potential complications include:

Milia: Tiny white bumps that appear as the skin heals (these usually resolve with gentle washing).
Enlarged Pores: Sometimes the pores appear larger temporarily after the skin is planed.
Infection: This is why the cleaning routine is so strict.
Persistent Redness: While most pinkness fades in 3 months, it can sometimes last longer.

Cost Considerations: The average cost for the surgeon’s fee is approximately $1,829. However, in San Antonio, you should also factor in the costs of the surgical facility, anesthesia fees, and post-op medications. Because this is usually considered a cosmetic procedure, it is rarely covered by insurance unless it is being used to treat precancerous lesions or reconstructive scars.

Comparing Dermabrasion to Laser Resurfacing

Many patients ask about the difference between chemical peels and laser resurfacing.

Feature	Dermabrasion	CO2 Laser	Deep Chemical Peel
Action	Mechanical Sanding	Thermal (Heat)	Chemical Reaction
Best For	Deep Scars, Rhinophyma	Wrinkles, Tightening	Pigmentation, Texture
Control	Operator Dependent	Computer Controlled	Concentration Dependent
Bleeding	Yes (Pinpoint)	Minimal (Cauterizes)	No

While lasers like the CO2 or Erbium:YAG are more common today because they cause less bleeding, dermabrasion is often more affordable and can be superior for certain types of mechanical scar revision.

At-Home Risks and DIY Warnings

You may see “dermabrasion kits” or “home peeling devices” online. Please avoid these. True dermabrasion involves reaching the dermis; doing this at home in a non-sterile environment without the ability to control the depth is a recipe for permanent scarring and severe infection. Professional supervision is non-negotiable for this level of skin resurfacing.

Frequently Asked Questions about Dermabrasion

How long do the results of dermabrasion last?

The improvement in scars and “pockmarks” is generally permanent. However, dermabrasion does not stop the clock on aging. While the skin we’ve smoothed will stay smoother, you will continue to develop new fine lines over the years due to natural aging and sun exposure. Long-term maintenance with medical-grade skincare and sun protection is essential.

Is the dermabrasion procedure painful?

During the procedure, you won’t feel pain because we use local anesthesia or sedation. Afterward, the “raw” phase feels like a very intense sting or burn, similar to a bad scrape or sunburn. This discomfort usually peaks in the first 72 hours and is well-managed with the pain medication we prescribe and by keeping the skin constantly moist with ointment.

Can dermabrasion remove tattoos?

Yes, dermabrasion was one of the original methods for tattoo removal. By sanding down to the level where the ink is stored in the dermis, we can physically remove the pigment. However, this often requires multiple sessions and carries a higher risk of scarring than modern laser tattoo removal, so we typically assess this on a case-by-case basis.

Conclusion

Dermabrasion is a powerful tool in skin resurfacing, offering a second chance at smooth skin for those struggling with deep scars or significant sun damage. Because it is a surgical procedure, the most important step you can take is choosing a board-certified expert who understands the nuances of skin anatomy and healing.
