Dermabrasion and chemical peeling are skin-resurfacing treatments that remove the outer layer of skin so smoother skin can regrow. Dermabrasion uses a fine rotating instrument; a chemical peel uses a controlled solution. They help people with acne scars, fine wrinkles, stretch marks, sun-related uneven tone, injury or surgical scars, and actinic keratosis.
- AnaesthesiaTopical or local with sedation; general for deeper treatment
- DurationA few minutes to about 1.5 hours
- Hospital stayOutpatient or day care
- Back to routineUsually about 2 weeks
What is dermabrasion and chemical peeling?
Dermabrasion is a controlled surgical removal of the outer skin layer using a wire brush or diamond-particle burr. It treats deeper problems such as acne scars, stretch marks, darker pigmentation, blackheads and enlarged pores. Microdermabrasion is a lighter, less invasive version for mild scarring and discolouration.
Chemical peeling removes the outer layer with a solution such as phenol, trichloroacetic acid (TCA) or alpha- or beta-hydroxy acids. It is mainly used for fine wrinkles and texture. Peels are light (epidermis only), medium (upper dermis) or deep (deeper dermis).
Both treatments need careful selection and preparation, and strict sun protection afterwards, because sun exposure during and after healing can cause lasting darkening of the skin.
Who is dermabrasion and chemical peeling for?
- People with acne scars, fine wrinkles, stretch marks or enlarged pores
- Uneven tone or pigmentation from sun damage
- Scars from accidents or earlier surgery
- Actinic keratosis (sun-damaged rough patches)
- Dermabrasion is not advised with active acne, active herpes infection, recent isotretinoin use (past 6 to 12 months), severe burns, recent peel, darker skin types or wrinkles around the eyes
- Chemical peels are not advised with a history of abnormal scarring, acne treatment in the past year, abnormal pigmentation, or red hair with very pale skin
How is it done?
- Preparation: medical review and instructions on medicines and diet; smokers usually stop 1 to 2 weeks before and after
- Peel pre-treatment may include tretinoin, hydroquinone for darker skin, acyclovir for those prone to cold sores (continued for two weeks after) and daily sunscreen
- Dermabrasion: local anaesthesia with sedation, or general anaesthesia for deeper work; the area is abraded and levelled, then dressed or covered with ointment
- Chemical peel: the skin is cleansed with a degreasing solvent, the solution applied for a set time, then washed off, neutralised and dressed
- Light peels may cause a burning feeling eased by cool compresses and a fan; deeper peels need local or general anaesthesia
- Dermabrasion usually takes a few minutes to about one and a half hours, typically in a single session
What is recovery like?
- After dermabrasion, skin typically returns to normal over 7 to 30 days; swelling fades within days and itching is common while healing
- Return to work is usually possible after about two weeks
- Avoid strenuous exercise, swimming and chlorinated water for about two weeks after dermabrasion
- After a peel, expect flaking, redness, swelling and irritation; about two weeks of rest is usually advised
- Strict sun avoidance and sunscreen for at least 12 months to prevent pigmentation
What are the risks?
- Scarring, bleeding or infection
- Reactivation of facial cold sores (herpes)
- Permanent darkening or lightening of the skin, especially with sun exposure
- Whiteheads (milia) that usually fade gradually
- Deep peels may need more anaesthesia, adding anaesthesia-related risk

Frequently asked questions
What is the difference between dermabrasion and a chemical peel?
Dermabrasion removes the outer skin layer mechanically with a rotating brush or diamond burr and is suited to deeper scars and texture problems. A chemical peel uses a controlled solution to remove skin to a chosen depth and is mainly used for fine wrinkles and texture. Your surgeon will recommend one based on your skin and concerns.
Can dermabrasion remove acne scars completely?
Dermabrasion can make acne scars smoother and less noticeable, but it cannot remove them completely. Deep or pitted scars may improve partially and sometimes need combined treatments. Results depend on scar type, skin type and healing.
Is dermabrasion suitable for darker skin?
Dermabrasion is generally not advised for darker skin because of a higher risk of pigment changes. Some chemical peels can be used with pre-treatment such as hydroquinone. A careful skin assessment is essential before choosing any resurfacing treatment.
How long does it take to recover from a chemical peel?
Light peels heal within days, while medium and deep peels cause flaking, redness and swelling and usually need about two weeks of rest. Deeper peels may cause discomfort for several days. Strict sun protection is needed for months afterwards.
Why is sun protection so important after resurfacing?
Newly healed skin is very sensitive. Sun exposure during and after treatment can cause permanent darkening of the treated skin. Daily sunscreen and avoiding direct sun for at least 12 months help protect the result.
