Step No. 3 In The Kat Burki 5 Essential Steps For Healthy Skin. Rarely addressed, our skin is best (and looks best) when its ph (potential hydrogen) level is mid-level to acidic - alkaline ratio, 0 (most acidic) to 14 (most alkaline). The skin’s barrier (acid mantle) is responsible for keeping lipids and moisture locked in as well as protecting against pollutants, toxins and bacteria. Optimizing the skin’s ph level is an important step towards overall skin health and protection from environmental damage and the aging process. We’ve created a unique complex of ph balancing ingredients. Fruit enzymes help to resurface the acid mantle. Once a strong barrier function is achieved, secondary conditions, such as hyperpigmentation and weakened elasticity can be addressed. Healthy acid mantle maintains moisture and keeps skin soft and smooth. Antioxidant dense turmeric strengthens while vitamin C from orange hydrosols, pumpkin seed oil and papaya support collagen. Bioactive pumpkin and papaya enzymes are rich in iron, zinc, C and K to infuse the skin with phytochemicals and fortifying compounds, while accelerating the exfoliation process.
