A member of the Truth In Aging community recently drew my attention to Baby Quasar Pure Silk ($60), an antiaging serum that is supposed to be used with the Baby Quasar at home LED device.  I have noticed that smearing on a good serum before using LED makes a significant difference and I tend to reach for Your Best Face Concentrate Antioxidants ($55 in the TIA shop). So I was interested in Pure Silk and whether I could be persuaded to use it instead.

My first impressions of Baby Quasar Pure Silk were good. The price wasn’t bad and it didn’t make outrageous claims for its straight forward formulation. Indeed, I was really pleased to see that hyaluronic acid was featured so prominently. Its water-binding and water-attracting attributes fill up the spaces between the connective fibers collagen and elastin in the dermis. Once upon a time, this stuff was extracted from cock’s combs. Pure Silk’s is from yeast.

A good complement with HA are the silk amino acids. With a low molecular weight, this ingredient penetrates well and is naturally hygroscopic (absorbs water from the air). Silk amino acids (also called silk proteins and sericin) are obtained by the hydrolysis of silk - a natural protein fiber. I also like the antioxidant ubiquinone, but am less impressed with saccharomyces copper ferment. This is extract of yeast fermented in the presence of copper ions that may have antioxidant properties. It shouldn’t be confused with copper peptides and there isn’t much information on it.

Although I wasn’t happy to see diazolidinyl urea/iodopropynyl butylcarbamate, which releases formaldehyde, as can DMDM hydantoin, plus a paraben, I was willing to give it a try. I tested Pure Silk with my Baby Quasar against YBF Concentrate Antoxidants, using one on each hand. After a session of the green light and then the flashing infra-red light, I compared results. The skin of both hands were visibly plumper, but I had to admit that the Pure Silk results were rather better. At least the immediate results.

I tend to think that YBF Antioxidants is a better bet longer term because it has (in its new formulation) ferulic acid and the powerful antioxidants, spin trap and lipochroman-6. I also prefer its light serum texture to Pure Silk’s gel-like consistency. Pure Silk isn’t going to wean me away from Antioxidants, but its pretty good and not a bad price.
