When you think of lactic acid you might be tempted to think of milk baths, but this organic acid is not derived from milk. Though it is true lactic acid is found in some soured dairy products, it is most naturally found in fermented fruits and vegetables and in the human body. Lactic acid is the reason that your muscles hurt after a long workout. It is also readily biodegradable and non-toxic to humans and the environment.
At Rocky, our lactic acid is created through the natural fermentation of sugar glucose found in molasses, making it completely natural and vegan.
In the context of lactic acid in personal care products, it’s an alpha hydroxy acid (AHA) that works to gently exfoliate the surface layer of your skin, sloughing off dead skin cells - leaving it smooth, more evenly toned and refreshed. It has skin softening abilities and is also known to promote collagen production.
Compared to other acids commonly used in skincare products like glycolic acid or salicylic acid, it is much more gentle and suitable for sensitive skin. Lactic acid may lower the pH of the area where it's applied, creating an environment inhospitable to bacterial growth. When used as a wash-off product like with our Kitchen Hand Wash, it will clean hands and leave them feeling luxurious.
Lactic acid is also a natural preservative and keratolytic agent, which in simple terms just means it helps improve the skin's ability to soak up and retain moisture. All in all, lactic acid keeps your skin smooth, toned, clean and moisturized.
You can find lactic acid in our Kitchen Hand Wash and in our Natural Haircare line.
