Lactic acid is a type of AHA present in many exfoliating skin care products. It removes the top layer of the dead skin cells and can help improve skin texture, reduce dark spots, smooth fine lines, and cleanse pores. Like glycolic and mandelic acids, lactic acid belongs to the alpha hydroxy acid(AHA) family. AHAs are water-soluble organic compounds that, in cosmetic formulations,
offer unparalleled benefits for the skin. Lactic acid presents an additional advantage that other AHAs don’t have.
Besides its ability to significantly improve the skin’s appearance, it helps keep it naturally hydrated.
Additional benefits of lactic acid
Much like its more aggressive counterparts, lactic acid has many known perks. It increases cell turnover and helps eliminate accumulated dead skin cells on the epidermis which is the top layer of the skin.
When using lactic acid in 12% concentrations, the skin gets firmer and thicker. As a result, there is an overall smoother appearance and fewer fine lines and deep wrinkles.
Can I incorporate lactic acid into my regime even though I have acne?
Skin with a tendency to get acne can be more sensitive to exfoliating therapies. Still, many doctors prescribe lactic acid chemical peels in low concentrations alongside antibiotic treatments. Using low concentrations has significantly improved the skin texture and reduced up to 90% of inflammatory lesions in people with acne in controlled clinical studies.
How to use lactic acid safely?
Even though it’s a milder AHA exfoliant, you shouldn’t use lactic acid too frequently. You risk over-exfoliating your skin and messing with its natural barrier. Consider using this effective skin resurfacing ingredient every other night unless your doctor says otherwise.
Follow the product’s directions carefully. Some preventive measures you could take before applying lactic acid — or any other AHA exfoliant — are:
-Making sure the lactic acid concentration is below 10%.
-Looking for products with a pH of over 3.5.
-Looking for products that warn about the potential effects of sun exposure after lactic acid use.
Conclusion
