Over the years (and still—as late every bit yesterday amongst 1 of my clients) I direct hold had many people enquire me many questions close the validity of SPFs, exemplifying the confusion that continues to surroundings the numbering system. Below are a few Q&As that volition hopefully aid to clear upwards whatever confusion you lot may have.

As I direct hold said fourth dimension as well as fourth dimension again, sunscreen is meant to maintain your peel from burning. You volition nonetheless have UV rays from this powerful star that heats our planet twenty-four hours inwards twenty-four hours out no thing the release on a bottle of sunscreen. Use it—absolutely, but don't experience falsely armed against all Sun damage.

If my moisturizer has SPF 8 as well as I lay my foundation on that has SPF 8, does that hateful I am protected similar an SPF xvi product?

I dearest this question—and the response is no! The highest SPF of whatever you lot are wearing is the Sun protection release you lot are getting. In other words, if your moisturizer has an SPF of fifteen as well as your foundation has an SPF 8, as well as thus you lot are getting SPF 15, non 23.



I’ve read some articles maxim that if you lot role this layering technique it somehow lowers the SPF value to the hateful average of the ii products. For instance, SPF fifteen + SPF 8 = an SPF value of eleven or 12. To me this sounds ridiculous, but maybe it’s true. Wearing whatever SPF products whenever you lot tin is e'er the best course of educational activity to take. And no thing the SPF values, you lot involve to have on a lot to a greater extent than production than you lot recall you lot create as well as you lot direct hold to reapply often to give-up the ghost on to give-up the ghost protection.

I read inwards 1 of your books that you lot don’t recall it is necessary to have on a sunscreen higher than SPF 15. Are you lot maxim that SPF xxx isn’t worth wearing?

No! What I explained inwards Timeless Skin was that many times people experience falsely protected when wearing high SPFs. This is exactly why the regulations for sunscreens direct hold been modified, as well as SPFs higher than l are non allowed past times the FDA. Absolutely, have on every bit high an SPF every bit you lot desire to, but know that amongst the higher numbers, you lot likewise give-up the ghost to a greater extent than sunscreen chemicals, as well as some peel may last sensitive to these. Regardless of the SPF, UV rays volition penetrate into your skin, at that spot simply isn’t whatever agency simply about that except within a edifice amongst no windows.

I am inwards no agency advocating wearing lower SPF sunscreens, but I am cautioning you lot to last aware that no sunscreen, no thing its SPF, is capable of protecting you lot completely for an extended menstruum of time. You must reapply Sun protective creams every bit good every bit have on roofing over your torso such every bit hats as well as protective clothing. If you lot direct hold a cream that you lot similar as well as it is an SPF 30, great! But know that if you lot volition last inwards the Sun for extended periods of time, you lot must reapply inwards club to give-up the ghost on the SPF benefits.

Adopt the American Cancer Society’s slogan, Slip, Slop as well as Slap. Slip on a shirt, slop on sunscreen, as well as slap on a hat. Only past times wearing sunscreen as well as roofing your peel amongst wearable as well as hats are you lot genuinely protecting your peel inwards the sun.
