Unlike harsher exfoliants, lactic acid breaks down the bonds between dead skin cells without causing dryness or irritation, making it an excellent choice for dry, dull, or sensitive complexions. Its alcohol-free formula ensures it is gentle on the skin, preventing further dryness or irritation. Naturally found in fermented plant sugars, our lactic acid is perfect for clean beauty formulations. It helps to smooth rough texture, reduce the appearance of uneven tone, and reveal brighter-looking skin and reduce dullness through gentle exfoliation. This ingredient is ideal for use in exfoliating serums, toners, face masks, and peels. As a humectant, lactic acid also helps draw moisture into the skin, reinforcing hydration while providing mild exfoliation. Our carefully crafted formula combines lactic acid with other beneficial ingredients to enhance its effectiveness. Whether you’re creating a clarifying peel or a softening night serum, this ingredient supports healthier-looking skin through regular use. Often, Lactic Acid is derived from milk, however, ours is made from maize or corn, and free from GMO. It is sold at an 80% concentration i.e. 80% Lactic Acid with 20% Water as an aqueous solution. How to use it How to Use Skin Care Depending on the strength of the dilution used, it can be used as a pH regulator, a moisturiser or as a skin peel. In the lower percentages, it reduces Trans Epidermal Water Loss (TEWL) by supporting the skin's barrier function. This has a good moisturising effect on the skin and can be used in water based serums, gels, toners, creams and lotions. Can help the skin to look fresher and younger. This is especially beneficial in night creams and anti aging products. When it is used at higher concentrations, it can have an exfoliating effect. It will improve the skin's appearance and help to remove surface debris and dead skin cells. Hair Care Used in a hair pack, it will cleanse a congested scalp for example, after a weave has been removed, having been on for several months. Other Use 1%-10%. Never use directly on the skin. Best added in the stage 3 (cool down) when making creams and lotions. Be aware that Lactic Acid can make creams and lotions thinner or unstable so you need to start with a very strong and stable cream or lotion. As a pH regulator, it can be used to move the pH number lower (more acidic) for when using Preservative K which only functions correctly in a narrow pH range. Suggested Blends It works well in conjunction with Vitamin A, B and C. Be sure to check the final pH level is not less than 3.5 when combining several acidic ingredients together.

FAQ's Frequently Asked Questions What does lactic acid do in skincare? It gently exfoliates the skin while attracting moisture, helping to reveal smoother, brighter, and more hydrated skin with regular use. It also helps to reduce hyperpigmentation and redness, promoting a more even skin tone. Is lactic acid suitable for sensitive skin? Yes. Its larger molecule size makes it gentler than other AHAs, making it a good option for sensitive and dry skin types. Can I use lactic acid daily in my skincare products? Yes, but start with a low concentration and increase as your skin builds tolerance. Products with up to 5% can typically be used daily. Monitor your skin for any signs of redness or irritation and adjust usage accordingly. What pH should my lactic acid product be? Aim for a final pH between 3.5 and 4.5 to ensure the lactic acid remains active and skin-safe. This ensures the lactic acid can work effectively to exfoliate and improve skin texture. Is this lactic acid vegan and cruelty-free? Yes, our lactic acid is 100% vegan, cruelty-free, and not tested on animals. Can I mix lactic acid with vitamin C or niacinamide?
