Rachel Great exfoliator! - My skin type is oily for the most part, but I still get a bit of skin that needs sloughed off. This product acts as a gentle exfoliant on dry, dead skin. And I love that no micro beads or gritty scrub are required - this makes exfoliating your face so easy! I use this serum once or twice a week, and I always notice a difference in the smoothness of my skin and overall tone & radiance. I'd highly recommend this serum!

Description
This pH of this formula is approximately 3.8 and Lactic Acid has a pKa of 3.8. The pKa value is the most important aspect to consider in formulating with acids as pKa implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing the efficacy of the acid and reducing the potential of developing irritation. Higher pH values in such a case would increase the concentration of salt, which counter-intuitively would make the formula even more irritating than if the formula was more acidic.Contraindications: Lactic Acid should not be used on sensitive, peeling or compromised skin. Please refer to additional sun protection note and other warnings in provided Directions.
