Glycolic AcidBenefits, how to use & safety
The smallest AHA, the biggest glow.
What is Glycolic Acid?
Glycolic acid is the smallest alpha hydroxy acid, derived from sugar cane. Its small size lets it penetrate quickly and exfoliate effectively, making it a favourite for dullness, rough texture and uneven tone.
How it works
It loosens the bonds between dead surface cells so they shed, revealing fresher skin. With regular use it also encourages collagen production and helps fade superficial pigmentation.
Key benefits
- Brightens dull skin
- Smooths rough texture and fine lines
- Helps fade surface dark spots
- Supports clearer pores
- Dullness
- Texture
- Dark spots
Best suited for: Normal and oily skin that tolerates exfoliation. Sensitive skin should choose lactic acid or PHA instead.
How to use it
Use 5–10% glycolic acid in the evening, once or twice a week at first. Rinse-off or leave-on formats both work. Always follow with sunscreen the next day, as skin becomes more sun-sensitive.
