Radical is way too tame


Uses ATP - an interesting anti-aging active


Too many ingredients that depend on a quick fix

I recently came across Radical Skincare, which is sold in high end department stores such as Barney’s. Radical’s approach (which is supposedly the result of years of research) is to create a potent blend of antioxidants and an efficient delivery system. Although not especially radical, it is worthy. But when I looked more closely at Radical’s Youth Infusion Age Defying Serum ($110 for 30ml), I found it rather tame.

The problem for me is that Youth Infusion goes for quick fixes and risks overwhelming the actives that are likely to bring long term benefits. For example, Radical makes much of it’s use of pullulan.

Pullulan is used to make breath strips. Combined with an alga it is used by the cosmetics industry to create something called Pepha Tight. This adheres to the skin and creates an instant tightening sensation. There are no actual benefits other than this superficial effect. The manufacturer of Pepha Tight explains in the product description that it fulfills a market demand for people who “don’t have the patience” to wait for an antiaging cream to do its thing.

Radical Skincare seems to regard its customers in the same way and its Youth Infusion also contains a quick hit hydrator. Xylitylglucoside anhydroxylitol xylitol is a sugar found in wheat and wood cellulose. It is thought to help the skin retain its natural moisture and boost levels of hyaluronic acid, a natural lubricant that assists in collagen production. There is no research that I can find to back this up and xylitol’s appeal isn’t enhanced by knowing that it is a common flavoring for toothpaste and gum.

There are also light deflecting minerals, such as mica and malakite that may reduce the appearance of wrinkles, but certainly not the wrinkles themselves.

A more radical approach and one that would get me to hand over my credit card for this serum would be to focus on optimizing the formula with its only really interesting ingredient: Adenosine triphosphate (or ATP) is the main energy source for the majority of cellular – and muscular – functions. This includes the synthesis of DNA. Living things use ATP like a battery – storing and using energy when needed. Topical use of adenosine for wound healing deficiencies and diabetes mellitus has produced promising results and in 2009 researchers found that direct intracellular delivery of ATP can accelerate the healing process of skin wounds at an “extremely fast” speed “never seen or reported in the past”. Ongoing research into topical ATP use hopes it will prove to be effective enough to reduce the need for skin grafts.

One of my favorite products (and one of the few that I know of) with ATP is Skin Nutrition's Cell CPR

    So glad you like Cell CPR Howard. Its expensive, but when you look at the quality of the ingredients and that they all have a role to play, it isn't bad value at all.

    I am not certain how to say this without sounding completely silly
    Two Timing Tightner lives up to it's name although I find it (personally)to be better in low light situations.
    The "instant tightening sensation" as you mention is there however so is a "sheen"
    and therefore highlighted pores in the nose and cheek areas. It does provide a smoothing, tightening and lifting effect to the sagging areas of the neck, cheek and forehead
    The effects remind me of PTR Instant Firmx although not as dramatic
    The value is there however since this a 1.7 oz (50 mL) bottle for 30.95 and a leave on serum that is lightweight and goes on smoothly
    Short term it works and hopefully will provide long term from the DMAE and other ingredients.
