For adults: sodium lactate is usually safe in creams and lotions and helps skin hold moisture. But it can make skin let other ingredients through more easily, so some safety panels limit how it’s used.
Choose products from reputable brands that follow industry safety limits. Prefer formulations intended for everyday use rather than high-strength professional treatments. Patch-test a small area (inner forearm) before using a new product. Follow label directions. If you use products with strong acids or prescription treatments, talk with a dermatologist before combining them and use sunscreen as instructed.
Safety reviewers (Cosmetic Ingredient Review and Canada Cosmetics Hot List) and an industry position paper flag two things: limits on concentration and pH, and that sodium lactate can act as a penetration enhancer. Avoid using high-concentration or leave-on products with sodium lactate without professional guidance, do not apply to broken or irritated skin, and stop use and seek advice if you get redness, burning, or a rash. Peer-reviewed reviews and Environment Canada list cancer and allergy risks as low, so those are not the main concern here.
