There are a large number of anti-wrinkle creams on the market. Some claim to reduce underye wrinkles, others claiming to reduce the appearance of fine lines on the face. A study in 2005 (which you can view here) evaluated the effectiveness of an “anti-wrinkle cream” on the subjective appearance of wrinkles. It showed a large proportion of patients were very happy with the effect of the anti-wrinkle cream on their skin.
We find that the products that have made our skin feel smooth and firm usually contain vitamin A, lactic and salicylic acids and Niacinamide really helps with having an even skin tone.
