Glycolic acid has become a staple in modern skincare due to its powerful exfoliating and brightening effects. Whether you’re targeting dull skin, dark underarms, or product buildup on your scalp, glycolic acid can be a game-changer—if used correctly.
What is Glycolic Acid?
Glycolic acid is a type of alpha hydroxy acid (AHA), derived from sugarcane. It’s water-soluble and has the smallest molecular size among AHAs, allowing it to penetrate the skin deeply. This makes it an effective exfoliant that removes dead skin cells, boosts cell turnover, and helps reduce pigmentation, fine lines, and acne.
How to Use Glycolic Acid on the Face
Start slow: Use 2–3 times per week if you’re new.
Cleanse your face first and pat dry.
Apply a glycolic acid toner or serum at night using a cotton pad or fingers.
Follow with a gentle moisturizer.
Use sunscreen every day as glycolic acid increases sun sensitivity.
How to Use The Ordinary Glycolic Acid
Use once daily in the evening.
After cleansing, saturate a cotton pad and sweep it across the face and neck.
Avoid eyes and lips.
Follow with hydrating products like hyaluronic acid or ceramide-rich moisturizers.
⚠️ Avoid using with retinol, vitamin C, or other exfoliating acids.
