Change Serum

Change Serum 15% Hydroxy Acid Complex

8% Alpha Hydroxy Acids (AHA): Glycolic, Lactic & Mandelic Acid
4% Poly Hydroxy Acid (PHA): Gluconic Acid
2% Beta Hydroxy Acid (BHA): Salicylic Acid
1%  Lipo Hydroxy Acid: (LHA): Capryolyl Salicylic Acid

This unique combination of mild acids act at different levels in the skin, they exfoliate or "unglue" dead skin cells, prevent blemishes by lowering pH and by direct antimicrobial action, even skin tone/reduce hyperpigmentation and visibly reduce mild scarring by stimulating elastin and collagen synthesis. BHA and LHAs are fat soluble and work deeper in the skin and hair follicles. Read more about the science here.

Change serum is a hydrating leave on formula that does not require moisturizing post application, we believe it can replace stronger, difficult to use peels and over time give you better results.

Bacteria implicated with acne only grows when pH is over 4 (1983 Greenman) – hence, low pH products are ideal for acne-prone skin. Acne sufferers typically have higher (less acidic) skin pH, which is optimal for acne growth (2017 Prakash).
