Milk baths envelop the skin in lactic acid, a natural alpha hydroxy. Whilst glycolic acid (another alpha hydroxy) is sourced from sugar cane, Lactic provides greater versatility as a dual exfoliant and potent skin hydrator. Lactic acid gently dissolves superficial dead skin to gently smooth and reveal a softer feeling skin. Lactic acid is also produced by the skin as a humectant. It is able to bind water to deeply moisturise and hydrate for maximum skin comfort. Whilst trying to fill a bath tub with warm goatās milk would be both expensive and a challenge, why not emulate Cleopatraās regime with AHA body cleansers, scrubs and moisturisers. Todayās modern formulas are vegan friendly and of course suitable for those who are lactose intolerant.
