I shall have to update my post on Five Best retinol creams very soon as I keep coming across better ones. Thanks to a post by 'Nimue', I took a closer look at PSF Retinol Nite Repair ($46). It looks to be a good product at a good price.
It packs its punch with a 1% concentration of pharmaceutical grade retinol (no retinyl palmitate masquerading as retinol here). Alpha lipoic acid is an interesting ingredient that is supposed to prevent vitamin C and E deficiency. Evidence is also accumulating that it is a powerful and versatile antioxidant able to "deactivate an unusually wide array of cell-damaging free radicals", according to the Berkeley University's Wellness newsletter.
An antioxidant helping hand is also given by the addition of vitamins C and E. In researching this post, I have also discovered that rosemary is a great antioxidant because it contains carnosic acid. It is also high in vitamin B6.
Counteracting the irritant effects of retinol are aloe, neem oil and willow bark, which has salicin (similar to aspirin) in it. Butylated hydroxytoluene (BHT) is a preservative that has been banned as a food additive in Japan and Europe. It is associated with hyperactivity in children and there have been some links to cancer. However, the World Health Organization says the research shows it is only toxic in massive doses. Furthermore, other studies suggest that the topical application of BHT may prevent some forms of cancer.
All in all, as Nimue says, if you are thinking about trying out a retinol cream, this may be a good one to start out with.
