Glycolic acid is a powerful exfoliating ingredient that has transformed modern skincare. Used in both over-the-counter products and professional treatments, it helps improve skin tone, texture, and clarity by removing dead skin cells and stimulating collagen renewal.
Whether you’re dealing with acne scars, uneven skin tone, or fine lines, glycolic acid could be the key to a smoother, brighter complexion—if used correctly.
What Is Glycolic Acid?
Glycolic acid is a type of alpha hydroxy acid (AHA) derived from sugarcane. Among all AHAs, it has the smallest molecular size, allowing it to penetrate deeply into the skin and accelerate exfoliation.
It works by breaking down the bonds between dead skin cells on the surface, allowing them to shed more easily—revealing fresher, healthier skin underneath.
Benefits of Glycolic Acid
| Benefit | How It Works |
|---|---|
| Improves skin texture | Removes rough, dead skin cells |
| Brightens dull skin | Promotes cell turnover and radiance |
| Reduces acne & breakouts | Clears clogged pores and reduces inflammation |
| Fades pigmentation | Helps lighten post-inflammatory hyperpigmentation |
| Minimizes fine lines | Stimulates collagen with consistent use |
| Preps skin for other products | Increases absorption of serums and treatments |
Who Should Use Glycolic Acid?
Glycolic acid is suitable for:
Oily or combination skin
Dull or textured skin
Acne-prone skin
Mild to moderate pigmentation
Early signs of aging
It may not be ideal for very sensitive or rosacea-prone skin without medical supervision.
Types of Glycolic Acid Products
1. Toners & Exfoliating Pads (5–10%)
Used 2–3 times per week for maintenance and mild exfoliation.
2. Serums & Creams (10–15%)
Stronger exfoliating formulas for visible texture or pigmentation issues.
3. Peels (20–70%)
Higher concentration peels used by professionals in clinics. These require proper pre-treatment and post-care routines.
How to Use Glycolic Acid Safely
Start slow – 1–2x a week with a low concentration (5–7%)
Use at night – Avoid combining with retinol or strong acids on the same day
Hydrate after – Apply moisturizer to avoid irritation
Wear sunscreen daily – Glycolic acid increases sun sensitivity
Watch for purging – Mild breakouts may occur during initial use
Side Effects to Watch For
Redness or stinging
Dryness or flaking
Increased sensitivity to UV
Temporary irritation if overused
Stop use and consult a dermatologist if you experience persistent burning or peeling.

| Type | Strength | Best For | Frequency |

Common Questions About Glycolic Acid
1. Can I use glycolic acid every day?
Not recommended for beginners. Start 2–3x/week and increase only if your skin tolerates it.
2. Can glycolic acid remove acne scars?
It helps fade post-acne pigmentation and improves skin texture, but deep scars may require laser or microneedling.
3. Is glycolic acid safe for dark skin?
Yes, but lower concentrations and clinic-guided use are advised to avoid post-inflammatory hyperpigmentation.
4. What shouldn’t I mix with glycolic acid?
Avoid combining with retinoids, vitamin C, benzoyl peroxide, or other strong acids unless advised by a skincare professional.
5. How long does it take to see results?
You may notice smoother skin in a week. Pigmentation and scars take 4–6 weeks of consistent use to fade.
