How citric acid benefits the skin
Citric acid treatments can brighten skin, shrink pores, treat mild acne, and correct dark spots and fine lines. When applied to skin, citric acid exfoliates the top layers of skin and sloughs off DEAD SKIN CELLS. Additionally, the speed of new cell turnover increases, which promotes NEW SKIN growth that can help alleviate the appearance of age spots, ACNE SCARS, small wrinkles and areas of uneven tone and texture. Of note, research on the ability of citric acid to exfoliate the skin examined much higher concentrations (20% for example) than are used in skin care products.

Benefits:
Acidulant (useful to adjust pH of products to make them more acid / less alkaline)
Chelating effect (neutralizes minerals to enhance activity of antioxidants & preservatives)
Buffering effect (helps to maintain pH between 2.5-6.5 & stabilizes active ingredients)
At high concentration shows typical AHA properties (moisturizing, peeling, smoothing, anti-wrinkle effects).
Use: For safe use do not use at >10% or at pH
