Ingredient Type: Chemical exfoliant

AKA: Glycolic acid, lactic acid, mandelic acid, citric acid, malic acid, tartaric acid

Purpose: There are two main types of acids used in skincare: Beta-hydroxy acids (BHAs) and alpha-hydroxy acids (AHAs). AHAs work to chemically exfoliate the outermost layer of skin, AKA shed dead cells to reveal healthier, brighter skin.

Benefits:

• Exfoliates to reveal healthier skin
• Evens out and brightens skin tone.
• Smoothes and firms skin texture
• Minimizes the look of pores
• Can reduce the appearance of fine lines and wrinkles

Best for: All skin types, however tweens and younger teens (under 15) should use cautiously, ideally in low concentrations (2-5%) and in gentle, well-formulated products like mild cleansers or moisturizers.

Why the caution? Tween and teen skin is often more sensitive due to hormonal changes and a thinner skin barrier. High-potency AHAs (above 5-10%) or frequent use can cause irritation, redness, or dryness, especially for sensitive or acne-prone skin.

How to use: Start with a product containing low-dose lactic acid (gentler than glycolic) once or twice a week, and always follow with moisturizer and daily SPF 30+ (AHAs increase sun sensitivity). Patch-test first to check for reactions.

When to use: AHAs are great for addressing uneven texture, mild acne scars, or dullness, but they’re not necessary for everyone. If breakouts or oiliness are the main concern, salicylic acid is often a better choice for young skin.

Doesn't mix well with: Retinol and other retinoids.
