Lift Active Retinol 0.2%.

"Vichy's new retinol product from their Lift Active line [...] contains 0.2 percent retinol which is a fair concentration but not one that is overly potent. [...] When it comes to choosing retinols over the counter go with reputable brands that are often going to have more money and research into [...] product formulation, so certainly Vichy is one brand that is well respected and backed by science. Not only does this contain 0.2 percent retinol that is a decent concentration that's effective, but it also contains peptides that work really well alongside retinol to help reduce the appearance of fine lines and wrinkles along with their prebiotic extract. The formulation also helps to ensure stability because you press on the tip to dispense. It's fragrance free so if you have sensitive skin and worry about fragrance this is a great one to try. It's a white milky serum that's fairly lightweight, fast absorbing, and non-sticky, so I personally feel that it's really ideal."
