Salicylic Acid - read more

Salicylic acid is a beta-hydroxy acid (BHA) found naturally in the bark of willow trees. BHAs are organic acids similar to alpha hydroxy acids (AHAs) used commonly in skincare preparations to treat the signs of aging, acne, and psoriasis through chemical exfoliation. Unlike AHAs, BHAs are lipid rather than water soluble, allowing them to penetrate the skin through follicles and aid exfoliation within pores. This property makes BHAs particularly useful in the treatment of oily skin, or those suffering from clogged pores and acne. In addition, BHAs have anti-inflammatory and anti-bacterial properties, and are known to help improve skin barrier function, increase skin thickness, and promote collagen synthesis. In Celloxylin MD 20EX Acid Peel, Apriori Beauty uses a unique form of encapsulated salycilic acid that is a first in the beauty industry! Encapsulation allows for both effective delivery of high levels of salicylic acid, and continued release throughout the day, allowing for prolonged smoothing and calming effects.
