First and foremost, forget about SPF when it comes to UV-induced skin aging. SPF, or sun protection factor, is simply a measure of how well a sunscreen can protect against UVB-induced sunburn. (1) While UVB does play a role in skin damage, it is not what is primarily responsible for the aging of skin. In other words, high SPF is not synonymous with high protection from photodamage. If a sunscreen prevents a sunburn yet allows for a “nice tan” (like many high SPF sunscreens), then said sunscreen is still allowing Continue reading

**Hopefully, readers see that this condition is far from exclusive to old women, and more over, that prevention in both males and females should begin in youth. In the series, it will become evident that prevention and care of osteoporosis must be done holistically and below the surface, this book is also a prevention tool against Continue reading
Self-Tanners and Potential Aging Effects
Self-tanning agents work by producing an artificial “tanning” process from the reaction between the proteins on the surface of skin and the reducing sugars (such as dihydroxyacetone (DHA)) of the self-tanner. DHA has been known for awhile to be a color additive, but it was only until recently that DHA formulations can act gradually and emulate a natural bronze-y tan without appearing too orange on most skintones. Their sweeping popularity is a testament to them being the obvious “no-brainer” choice for a substitute “tan” when it is now commonly known that real tans achieved by UVB and UVA exposure lead to skin wrinkling, sagging, and discoloration.
But what if self-tanners also age skin? How would that be possible? A keen eye and a Continue reading
