If your skin looks dull no matter how much moisturiser you use, the problem usually isn't hydration — it's the layer of dead surface cells sitting on top. That's exactly what glycolic acid is for.
What is glycolic acid?
Glycolic acid is an alpha hydroxy acid (AHA) with the smallest molecule size of any AHA, which lets it work efficiently at the skin's surface. It loosens the bonds holding dead skin cells together so they shed naturally — revealing the smoother, brighter skin underneath.
What a glycolic toner does
- Smooths texture — gently dissolves rough, flaky build-up
- Fades dark spots — speeds up cell turnover so post-blemish marks fade faster
- Evens tone — regular use promotes a visibly more uniform complexion
- Boosts your other products — serums and moisturisers absorb better on exfoliated skin
How to use it
Apply in the evening after cleansing: sweep a soaked cotton pad over the face, avoiding the eye area. Start 2–3 nights a week and build up. Always follow with moisturiser, and wear SPF in the morning — fresh skin is more sun-sensitive.
