The strength of an acid depends on its ability to exfoliate the skin and address specific skin concerns. Salicylic acid is generally considered stronger than glycolic acid.
Here's why:
- Salicylic acid is a beta hydroxy acid (BHA), while glycolic acid is an alpha hydroxy acid (AHA). BHAs are oil-soluble, allowing them to penetrate pores and exfoliate from within.
- Salicylic acid can reach deeper layers of the skin than glycolic acid, making it more effective for treating acne, blackheads, and clogged pores.
- Glycolic acid is water-soluble, making it better suited for surface exfoliation. It's more effective at addressing hyperpigmentation, fine lines, and wrinkles.
Both acids can be effective, but the choice depends on your skin type and concerns.
Here's a quick comparison:
- Salicylic acid: Stronger, oil-soluble, penetrates pores, targets acne, blackheads, and clogged pores.
- Glycolic acid: Less strong, water-soluble, exfoliates surface, targets hyperpigmentation, fine lines, and wrinkles.
