Chemical peeling is a skin resurfacing technique by applying a chemical solution to the skin for various treatment intentions. Types of chemical peels performed by dermatologist include superficial peel, medium depth peel and deep chemical peel, in increasing order of depth. Chemical peels treatment may be combined with other treatments such as lasers, light or microdermabrasion.
Benefits of Chemical Peels:
1. Chemical Exfoliation of Skin
2. Can Help Improve and Reduce Acne, Blackheads & Whiteheads
3. Helps to lighten pigmentation/hyperpigmentation of the skin
4. Reduce the appearance of fine lines/acne scars
5. Helps to even out skin tone
6. Brightens Skin
7. Improve Skin Texture & Radiance
7 Common Acids used In Chemical Peels:
1. Citric acid
2. Lactic Acid – Mild peel for skin rejuvenation
3. Salicyclic Acid – Helps to break down comedones (blackheads and whiteheads)
4. Glycolic Acid – Mild peels for skin rejuvenation
5. Azelaic Acid – Kills acne bacteria and reduces inflammation
6. Trichloroacetic Acid – Medium-depth peel that helps to lighten the skin tone.
7. Kojic Acid – Tyrosinase inhibitor. Prevents melanin production. Lightens scar tissue
The type of chemical peel done will depend on the individual’s skin conditions and needs. There are many different types and combinations of peels that can be done and the doctor will decide what type of peel will suit you after a thorough assessment.
Side effects of Chemical Peels:
Generally, when an appropriate chemical peel is used, the risks of side effects are low. Side effects of chemical peels include erythema, itch, dryness, uneven skin tone, burns and the risks of side effects tend to be stronger with deeper peels.
How Chemical Peels are performed:
- Cleansing of the skin
- Application of chemical peel
The acid formulation may be applied with a brush or cotton pad all over the face or sometimes over affected areas, similar to how you would apply a toner on your face. Multiple layers may sometimes be applied. - Neutralisation
After a few minutes (depending on the type of peel used), neutralisation with water/solution may be needed.
What to expect post-treatment:
Day 0 (Treatment Day): May experience redness, dryness, feeling of ‘tightness’
Day 1 : Skin feels more dry (may cause some itch), may experience mild redness
Day 2-6: Skin starts to flake or peel over the next few days and generally this peeling process lasts for about 2-5 days for most individuals
Day 7: By the end of a week after the chemical peel is performed and skin peeling/flaking has completed, skin looks brighter, smoother and more radiant.
Post Treatment Home Care Tips:
- Try to avoid sun exposure, or limit sun exposure as much as possible. Use a sunscreen and other sun protection measures such as a hat or umbrella if sun exposure is unavoidable
- Moisturise (but do not overdo it, especially for those with acne-prone/oily skin as this may trigger an acne outbreak). You will notice your skin tends to be more ‘thirsty’ in the few days after chemical peel.
- Avoid using facial wash and toners containing retinol or acids or alcohol for about 3 days after chemical peel is done as these may cause irritation, especially for those with sensitive and/or dry skin.
- Avoid picking at/peeling off skin that has started peeling as this may cause uneven skin tone.
Conclusion
A chemical peel is an ideal treatment for clients who have mild to moderate sun damage and/or fine lines. Chemical Peels require little downtime and great results are seen after just a few treatments. Medium depth peels can be used for acne scars and other skin imperfections and can stimulate collagen production, which reduces the appearance of fine lines, wrinkles and scars. Deep peels are typically used to treat deep scarring or wrinkles. Dermatologists recommend that patients wait 4-6 weeks between chemical peels, depending on the depth of the peel. Chemical peels can be performed to target freckles, deeper wrinkles, superficial scars and photo-damaged skin etc.
