The Research

Complexion health, vitality and beauty are highly dependent upon the acidic pH of the Stratum Corneum, the skin’s outermost layer. Skin protects itself from the breakdown of its connective tissues ) by up-regulating enzymes that assist in collagen and elastin connective tissue synthesis. These enzymes require acidic surface conditions to function optimally. Breakouts, premature ageing, pigmentation and other signs of environmental damage can occur when the skin is too alkaline (the opposite of acidic). A nightly cleanse with a complex of hydroxy acids, phospholipids and amino acids can assist in gently recalibrating skin pH back to a healthy, acidic state, helping to restore clarity and firmness.

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.
Oat Amino Acids gently solubilise and thoroughly remove oil, dirt, debris, sunscreen and makeup residues from the skin’s surface, eliciting a calming effect on skin while boosting hydration and fortifying barrier function.
Australian Botanicals have the potential to calm environmental skin irritation and help recalibrate skin pH to a healthier acidic level.
Skin Identical Ceramide Complex supports natural cleansing mechanisms, while amplifying hydration and increasing Natural Moisturising Factors (NMFs) to fortify barrier function and skin resilience.
Acetyl Hexapeptide-37 + Hexapeptide-10are proteins that support skin moisture by reducing Trans-Epidermal Water Loss (TEWL) and increasing hydration levels in the Stratum Corneum. In hyper-sebaceous skin, they calm the appearance of redness to cultivate a clearer, more radiant tone.
