In recent years, the trend of "acid peeling" has gained significant traction online. Originally a medical aesthetic procedure involving the application of acidic substances with a brush to areas with blackheads or acne, the term now encompasses any use of acid-based skincare products at home, beyond professional treatments in clinics or salons.
Chemical peeling is a form of chemical exfoliation, typically involving the application of skincare products or medications containing acids at specific concentrations. Ingredients like hyaluronic acid, tranexamic acid, or ascorbic acid do not fall under this category. The term "chemical peeling" commonly refers to treatments using salicylic acid, alpha hydroxy acids (AHAs), retinoic acid, azelaic acid, and similar substances.
Acid peeling addresses various skin concerns arising from aging, poor diet, environmental changes, and more, while boosting metabolism. Issues like acne, blackheads, dry lines, fine wrinkles, dullness, uneven skin tone, rough texture, and excessive oiliness can all be improved through acid peeling.
While chemical peels offer benefits, many lack a thorough understanding of them:
Effects of Different Acids:
Fruit acids accelerate skin renewal, brightening complexion, evening out discoloration, and refining texture. Being relatively gentle, they are ideal for beginners.
Salicylic acid penetrates deeper than fruit acids and, with its oil-controlling properties, is more effective against blackheads, acne, and clogged pores. However, it is not suitable for dry skin.>Azelaic acid, commonly known as rhododendron acid, inhibits melanin production and deposition, suppresses fatty acid synthesis, and reduces keratin buildup. It is suitable for dull skin with significant acne scars and residual marks.
Retinoic acid effectively treats acne but is classified as a prescription drug due to its high irritation potential. For acne removal, consult a dermatologist at a reputable hospital instead of self-medicating.
While chemical peels boost skin metabolism, they also make skin vulnerable, causing redness, sensitivity, dryness, and flaking. Once the skin barrier is compromised, it may become intolerant to other skincare products, potentially worsening skin issues and leading to severe breakouts.
How to avoid skin damage from chemical peels?
1. Always perform a patch test before acid peeling. Apply the product behind your ear or on the inner wrist first. Only proceed to the face if no adverse reactions occur. For first-time users, start with low-concentration, mild acids to gradually build skin tolerance.
2. Post-peel skin has weakened protective functions and is highly susceptible to sunburn. Strict sun protection is essential after acid peeling.
3. Avoid excessive or frequent acid peels, and exercise extreme caution with high-concentration acids. For potent alpha hydroxy acids (AHAs) or salicylic acid treatments, consult a licensed medical aesthetic clinic or hospital dermatology department.
Prioritize thorough post-peel skincare.
Additionally, acid peels are not recommended for pregnant or breastfeeding individuals, those with sensitive skin, visible capillaries, or compromised skin barriers.
