This is a very basic, ultimately disappointing sunscreen with a price that is likely to discourage the liberal application that is essential. Stabilized avobenzone is on hand for reliable UVA protection, but alcohol plays a fairly strong supporting role in this sunscreen, which would be to your skin’s detriment. Alcohol is always irritating and drying and causes free-radical damage, not the best for skin. Plus, the price tag and the small quantity make it unlikely you will apply this liberally, which is how sunscreen must be applied.
Super Fluid does have a silky texture and nearly weightless finish, but it’s too short on redeeming qualities to make it a worthwhile purchase. As for the “prevent 90% of skin aging” claim, that can be said of any well-formulated sunscreen that provides broad-spectrum protection—and Super Fluid UV Defense SPF 50 doesn’t qualify as the best sunscreen around.
Alcohol-Based Skincare Products: Alcohol helps ingredients like retinol and vitamin C penetrate into the skin more effectively, but it does that by breaking down the skin's barrier—destroying the very substances that keep your skin healthy over the long term (Biochimica et Biophysica Acta, 2012 and Journal of Hospital Infection, 2003).
A significant amount of research shows alcohol causes free-radical damage in skin even at low levels (Biochimica et Biophysica Acta, 2012). Small amounts of alcohol on skin cells in lab settings (about 3%, but keep in mind skin-care products contain amounts ranging from 5% to 60% or greater) over the course of two days increased cell death by 26%. It also destroyed the substances in cells that reduce inflammation and defend against free radicals—this process actually causes more free-radical damage. If this weren't bad enough, exposure to alcohol actually causes skin cells to self-destruct (Alcohol, 2002).
Research also shows that these destructive, aging effects on skin cells increased the longer skin was exposed to alcohol; for example, two days of exposure was dramatically more harmful than one day, and that's at only a 3% concentration (Alcohol, 2002). In fact, the effect of inflammation in the skin is cumulative, and repeated exposure to irritants contributes to a weakened skin barrier, slower healing (including of red marks from breakouts), and a dull, uneven complexion (Aging, 2012 & Chemical Immunology and Allergy, 2012).
