Skin Care Myths Debunked

Unless we do a significant amount of our own research, we may never know whether that skin care "hint" or "handed-down-the-generations-truth" is really true! Does it really matter..? Well, sometimes it does, and sometimes it probably won't hurt you. But that doesn't mean that it will help you either!

Here is a list (by no means exhaustive) of popular myths....

1. Adding several layers of product, each with its own SPF, will increase your protection

Unfortunately, this one is not true. Three products applied in sequence (like a foundation SPF 10, moisturizer SPF 10 and sun screen SPF 20) does not give you the combined protection of SPF 40. It only gives you the protection of the highest SPF that you apply (SPF 20 in this example).

2. A higher SPF is always better

This is true, but only barely! Let me explain... The biggest danger of a high SPF sunscreen is the false sense of security that it gives. The amount of light that induces redness in sunscreen-protected skin, divided by the amount of light that induces redness in unprotected skin is the SPF. It is mainly a measure of UVB protection and ranges from 1 to 45 or above.

A sunscreen with SPF 15 blocks close to 93% of UVB radiation, while an SPF 30 will block around 97% of UVB. But the SPF "number" only indicates protection against UVB rays. In order to be protected against UVA and UVB rays, use a sunscreen containing physical blockers, such as titanium dioxide and zinc oxide.

3. Indoor tanning is safe

If you have any doubt about this myth, read this earlier post...

This myth has it's foundation in another myth: you have to have sunburn to get skin damage... which is also untrue. Tanning is skin cells in trauma. There is no other way of explaining it. In response to UV damage, skin cells produce melanin to protect themselves. However, one damaged cell can start a deadly melanoma growing.

I saw the Riversol products in the Emmy swag bags as well as in numerous Canadian beauty mags. All the make up artists swear by dermatologist Dr. Rivers skincare line. Samples or products? Where can you help me find them?? I want them for my fashion and film make up kits.
