Why should you choose a chemical free sunblock? Chemical sunscreen ingredients—often with names ending in -salate or -benzone—can give a better look and feel to sun-care products than physical sunscreens since they tend to sink into skin readily and dry clear. However, the price your skin pays being exposed to them may not be worth it. Conventional sunscreen is loaded with chemicals, well-established carcinogens and oxybenzone (an endocrine disruptor) that may generate free radicals when exposed to ultraviolet light. Some researchers even suspect oxybenzone to be the hidden cause of the increase in melanoma.
At one time the only sunscreen ingredient we had available was PABA (para-aminobenzoic acid), thankfully they banned it. Another chemical, Oxybenzone, probably the most notorious UV filter, was approved by the FDA way back in 1978. Also referred to as BP3, it’s a member of the phenol family that has become so omnipresent, it’s been estimated that traces can be found in the urine of 96 percent of the U.S. population. In a 2004 study, researchers found that on the first day after applying a sunscreen with oxybenzone, both young men and postmenopausal women experienced a drop of testosterone levels. The current consensus on oxybenzone is that the hormone fluctuations are not clinically significant.
On the other hand, physical sunscreens can be helpful for anyone with sensitive skin since they’re less likely to exacerbate irritation and redness. If you like the idea of chemical-free sunscreens look for zinc oxide, or titanium dioxide a physical blocker. The quality of the sunblock you choose matters. Nanoparticles are small enough to penetrate cell membranes, particle must be 50 nanometers or less to penetrate a cell membrane.. Instead of nanoparticles, some sunscreen makers use “micronized” particles—basically, these are just slightly larger than nanoparticles, but still tiny. To be exact, a nanoparticle is less than 100 nanometers in diameter, so micronized zinc oxide or titanium dioxide must be larger than this.
Skinceuticals Physical Fusion UV Defense Sunscreen SPF 50.
It provides broad-spectrum sun protection 50 from both burning and aging sun rays, it also provides a universal tint that enhances your skin tone and boosts radiance. I like it because it is light and doesn’t look pasty or thick.
It glides on smooth and doesn’t leave behind any oily or white residue. Water-resistant for up to 40 minutes, the lightweight formula melts into skin, boosting radiance and increasing your skin’s defenses to keep you protected from premature signs of aging and damaging sun rays. It is a great chemical free sunblock.
