Skin Conditions
Blemishes
Alpha and Beta Hydroxy Acids gently recalibrate skin pH to a healthy acidic level, helping to reduce acne-causing bacteria and refine the appearance of pores whilst delivering instant luminosity. Salicylic Acid acts as an anti-inflammatory agent and penetrates deep into pores to decongest excess sebum, dirt and debris. Ceramides encourage natural cleansing mechanisms within the skin. Australian SolarRepair Botanicals help to regulate sebum production.
B
Dry Skin
Alpha and Beta Hydroxy Acids gently recalibrate skin pH to a healthy acidic level, boosting skin resilience, smoothness, hydration and clarity. Lactic Acid provides ultimate skin hydration and refines texture. Ceramides augment Natural Moisturising Factors within the skin. Australian SolarRepair Botanicals replenish skin cells and increase hydration.
DS
Pigmentation
Alpha and Beta Hydroxy Acids gently recalibrate skin pH to a healthy acidic level, working to boost skin cell renewal and fade epidermal pigmentation, evening out skin tone, texture and achieving instant clarity and radiance. Lactic Acid targets and brightens hyperpigmentation and treats sun damage. Australian SolarRepair Botanicals help to boost natural solar defence mechanisms to prevent further pigmentation from the sun.
P
Rosacea
Alpha and Beta Hydroxy Acids gently recalibrate skin pH to a healthy acidic level, calming inflammation and strengthening its barrier function. Salicylic Acid acts as a powerful anti-inflammatory, reducing redness and irritation within the skin. Ceramides encourage gently cleansing mechanisms and replenish the skin’s natural barrier function. Australian SolarRepair Botanicals help to boost skin resilience.
R
Sensitivity
Skin that is alkaline is often sensitive or sensitised. Alpha and Beta Hydroxy Acids gently recalibrate skin pH to a healthy acidic level, reducing irritation and strengthening barrier function. Ceramides further fortify skin resilience and encourage gently cleansing mechanisms within the skin. Australian SolarRepair Botanicals help to strengthen skin resilience.
S
Sun Damage
Alpha and Beta Hydroxy Acids gently recalibrate skin pH to a healthy acidic level which in turn, deactivates ageing enzymes that breakdown collagen and instead, activates youth enzymes that stimulate and promote collagen production. This results in a youthful, radiant complexion and increased skin firmness and hydration. Hydroxy Acids help to reduce inflammation within the skin and increase its resilience against sun damage. Ceramides encourage natural cleansing mechanisms and healthy barrier function. Australian SolarRepair Botanicals help to repair solar-induced DNA damage.
