Understanding Lactic Acid and Glycolic Acid
Both Lactic and Glycolic Acid are AHAs, meaning they exfoliate the skin by breaking down dead skin cells. However, their molecular structures make them suitable for different skin types and concerns.
| Feature | Lactic Acid | Glycolic Acid |
|---|---|---|
| Molecule Size | Larger (gentler) | Smaller (more potent) |
| Best For | Dry, sensitive skin | Oily, acne-prone skin |
| Hydration Factor | Retains moisture | Can be drying |
| Exfoliation Intensity | Mild | Strong |
| Common Uses | Hydration, glow-boosting, pigmentation | Acne scars, deep exfoliation, fine lines |
Benefits of Lactic Acid
Lactic Acid is a gentler exfoliant derived from milk or plant sources. It works well for people with dry or sensitive skin who want to brighten their skin without irritation.
- Boosts Hydration – Unlike other acids, it helps retain moisture, making it ideal for those struggling with dryness.
- Improves Skin Texture – Regular use promotes a smoother, more radiant appearance.
- Fades Dark Spots – Helps even out skin tone over time.
