Description
Lactic acid is an alpha hydroxy acid (AHA) naturally found in milk and produced via fermentation. As one of the gentler AHAs, it is ideal for sensitive or dry skin. Its larger molecular size allows it to penetrate the skin more slowly, reducing irritation compared to smaller-molecule AHAs like glycolic acid.
It exfoliates the outermost layer of the skin (stratum corneum), improves hydration, and enhances skin texture, making it highly effective for treating a wide range of dermatological concerns, including melasma, acne scars, photoaging, and pigmentation disorders.

How Lactic Acid Works on Skin
Lactic acid breaks down desmosomes—protein bridges between skin cells—which loosens the bonds holding dead cells together. This process promotes skin shedding, improves radiance, and accelerates cellular turnover.
Moreover, lactic acid enhances skin hydration by stimulating the production of natural moisturizing factors like ceramides. It also improves epidermal thickness and helps stimulate collagen synthesis, which can reduce the appearance of fine lines and wrinkles.

Clinical Benefits of Lactic 40 Peel
Hyperpigmentation and Melasma
Lactic acid has shown superior performance in reducing pigmentation compared to glycolic acid. In a randomized trial, a 60% lactic acid peel significantly reduced melasma severity in 80.4% of participants, demonstrating its efficacy in managing uneven skin tone and dark patches.
Clinical data on lactic acid efficacy for melasma
Acne and Post-Acne Scarring
Lactic acid is beneficial for acne-prone skin due to its ability to reduce follicular hyperkeratinization and control sebum. A study on 40% lactic acid peels showed a reduction in both inflammatory and non-inflammatory acne lesions without major side effects.

Anti-Aging and Wrinkle Reduction
As skin ages, collagen production slows down, leading to wrinkles and sagging. Lactic acid counteracts this by stimulating fibroblast activity and improving dermal thickness, especially when used at higher concentrations such as 40%.

Frequently Asked Questions
Q: Is this peel suitable for dry or sensitive skin?
Yes. Lactic acid is a humectant, meaning it draws moisture into the skin. However, a patch test is essential to avoid unexpected irritation.
Q: How long do I leave it on?
Start with 30 seconds for the first use. Gradually increase to a maximum of 3 minutes as tolerated.
Q: Can I combine it with retinol?
No. Avoid using retinol, benzoyl peroxide, or other exfoliants for at least 5 days before and after use.
Q: Will my skin peel after use?
Mild flaking is normal. However, visible peeling is not necessary for the product to be effective.
Q: How often can I use this peel?
Use it once every 10–14 days. Overuse can lead to over-exfoliation and barrier damage.
