Glycolic acid can help reduce the appearance of some acne scars, particularly those caused by discoloration or hyperpigmentation. It works by exfoliating the top layer of skin, revealing smoother and more even-toned skin underneath.
However, glycolic acid cannot completely remove deep, pitted acne scars. These scars are often caused by damage to the deeper layers of skin and require more intensive treatments like laser resurfacing, microneedling, or fillers.
Here's how glycolic acid can help with acne scars:
- Exfoliation: Glycolic acid helps remove dead skin cells, revealing healthier skin beneath. This can reduce the appearance of red or brown marks left behind by acne.
- Hyperpigmentation: It can help lighten dark spots caused by post-inflammatory hyperpigmentation, a common side effect of acne.
Important Considerations:
- Concentration: The effectiveness of glycolic acid depends on its concentration. Higher concentrations may be more effective but can also cause irritation.
- Consistency: It's important to use glycolic acid regularly for optimal results.
- Sun Protection: Glycolic acid can increase skin sensitivity to the sun. Always wear sunscreen after using products containing glycolic acid.
In summary, glycolic acid can be a helpful tool for reducing the appearance of some acne scars, but it's not a miracle cure. For deeper scars, other treatments may be more effective.
