I have been using Apskin Ultra Antioxidant Serum and Apskin Ultra Antioxidant Face Cream since May 2022. I have sensitive skin and very sensitive eyes, I can't stand any paraben or perfume in skin products. The first time I tried Apskin Ultra Antioxidant Serum, when I saw a small irritation (redness like being bitten by mosquito or insect) on my face. I put on this Serum at night before bed. Surprisingly, in the morning the irritation started to fade out. I also notice some improvement on my face and neck after I applied these products regularly before bed. My face feels so soft and smooth, hydrated and firmer (without the feeling of tightness, like other skin products). These are the best serum & cream I have used, they work exactly like they claimed to be, made in Australian from Australian apples and the prices are affordable, especially when they are on specials at Woolworths. Thank you Dr. Vincent for your hard work in researching and producing these products. I have been introducing these products to many friends ever since.
