Here's a detailed description of Lactic Acid in cosmetics:
What is Lactic Acid?
Lactic Acid is an alpha-hydroxy acid (AHA) derived from milk or produced synthetically. It's a natural humectant, attracting and retaining moisture in the skin.

2. Hydrating: Attracts and retains moisture, leaving skin feeling soft and supple.
3. Brightening: Fades hyperpigmentation, age spots, and freckles.
4. Anti-aging: Stimulates collagen production, reducing fine lines and wrinkles.
5. Antibacterial: Soothes acne, reduces inflammation, and prevents future breakouts.
Cosmetic Uses:
1. Cleansers
2. Toners
3. Moisturizers
4. Serums
5. Face masks
6. Peels
7. Body lotions
Concentration:
Typically ranges from 5-15% in cosmetic products, depending on the desired benefit and skin type.
Skin Types:
Suitable for all skin types, including sensitive skin. However, start with a lower concentration and gradually increase as needed.
Precautions:
1. Patch test: Before using a new product containing Lactic Acid.
2. Sun protection: Use sunscreen with at least SPF 30, as Lactic Acid can increase sun sensitivity.
3. Combination products: Avoid using with other exfoliants or harsh ingredients.
Fun fact:
Lactic Acid is also used in food preservation and as a natural preservative in cosmetics!
