The Research

The pH of the skin’s outermost layer, the Stratum Corneum, is vital to complexion health, vitality and beauty. The ideal state of the Stratum Corneum is acidic, as these conditions maintain the up-regulation of enzymes critical to the synthesis of collagen and elastin (skin connective tissues that provide skin structure and firmness), as well as helping to prevent collagen breakdown, sensitivity, breakouts and infection.Throughout life, skin becomes more alkaline as a result of intrinsic ageing and environmental damage. This leads to an up-regulation of enzymes that break down skin connective tissues, leading to premature ageing, wrinkles and sagging.Recalibrating and maintaining the acidic pH of skin is possible via a nightly regime of topically applied hydroxy acids which help to reverse the effects of facial ageing and environmental damage.

The Clarity Actives

Salicylic Acid is a lipid-soluble Beta Hydroxy Acid which enhances skin clarity and texture by decongesting pores and calming irritation and redness.
A Complex of Skin Identical Alpha Hydroxy Acids (including Lactic + Citric Acid) refines skin tone and texture while enhancing skin radiance by encouraging optimal desquamation processes to reveal a clearer, more balanced complexion. By recalibrating skin back to acidic levels, AHAs support cellular renewal and connective tissue synthesis, while amplifying skin firmness and hydration.
Australian Botanicals have the capability to support skin clarity while reducing a feeling of sensitivity.
