What is the difference between AHA and BHA exfoliants?

AHAs (alpha hydroxy acids like glycolic and lactic acid) are water-soluble and work on the skin surface — best for dry skin, dullness, and surface pigmentation. BHAs (beta hydroxy acids like salicylic acid) are oil-soluble and penetrate into pores — best for oily, acne-prone skin.

How often should I use a chemical exfoliant?

Start with once per week and increase to 2-3 times per week as your skin adjusts. Never use a chemical exfoliant on the same evening as retinol. Always use SPF 50 the following morning, as exfoliants increase photosensitivity.

Which exfoliant is best for brightening skin in Pakistan?

For brightening, glycolic acid (AHA) is the most effective exfoliant. It has the smallest molecular size of all AHAs, allowing it to penetrate deepest and deliver the most significant brightening results. For sensitive skin, lactic acid is a gentler alternative.

Can I use AHA and BHA together?

Yes, but not on the same evening if you're a beginner. Once your skin is accustomed to chemical exfoliants, you can use an AHA/BHA combination product or alternate between them. Always follow with SPF 50 the next morning.
