10% Ascorbyl Tetraisopalmitate (ATIP)

Ascorbyl tetraisopalmitate (ATIP) is one of the most stable forms of vitamin C on the market. Upon topical application, ATIP has an 84% conversion rate into free L-ascorbic acid and demonstrates superior absorption due to its lipophilic (oil-loving) nature. Ideal for sensitive skin types, ATIP can penetrate skin on an enhanced level, ensuring controlled and targeted penetration and reducing the likelihood of irritation. ATIP is a potent antioxidant and prevents cell damage from solar radiation and environmental aggressors, and has been shown to exert free radical scavenging effects within 30 minutes for up to 40 hours post application. To support youthful skin, ATIP also reduces the appearance of uneven skin tone and supports collagen production to combat fine lines and general skin ageing.

Coenzyme Q10 (CoQ10)

Coenzyme Q10 is found in every cell and tissue within the human body. It is a powerful antioxidant involved in numerous biological functions, including energy production and stabilising free radicals. Coenzyme Q10 levels decrease with age, resulting in the reduced ability to produce collagen and elastin. Topically applied, this ingredient assists in neutralising free radical damage and reversing the visible signs of ageing. In Effica C, coenzyme Q10 is what provides the formula its distinctive lemon-like colour.

Hydrolysed Tomato Skin (Lycopene)

Powerful antioxidant to combat solar radiation and pollution-based free radical damage. In addition to superior antioxidant benefits, lycopene offers protection to cells to help fight the signs of ageing and support skin health. When used in combination with other antioxidants, lycopene is able to enhance the protective benefits of other antioxidant ingredients such as vitamin C, resulting in a more effective and superior formula.

Betaine

Acts like a humectant and can also act to control and maintain water balance in the skin. It counteracts skin irritants and assists in reducing skin irritation.
Finding effective and stable vitamin C derivatives is always a challenge for formulators and Ascorbyl tetraisopalmitate (ATIP) ticks all the boxes. It deeply absorbs through the skin’s lipid network to enable gentle and rapid penetration to target skin cells. ATIP is acid free and beneficial for even the most sensitive skin types. It offers all the benefits of antioxidant protection, anti-ageing and skin brightening of the benchmark ingredient L-ascorbic acid.
