Understanding UVA / UVB - Mineral based sunscreens.

Updated: Mar 2, 2018

We often associate a glowing complexion with good health, but skin color obtained from being in the sun – or in a tanning booth – actually accelerates the effects of aging and increases your risk for developing skin cancer.

⠀⠀⠀⠀⠀⠀⠀⠀⠀ Over time, the sun's ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers break down, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. So while sun damage to the skin may not be apparent when you're young, it will definitely show later in life. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ When your skin is exposed to the radiation of the sun’s UV rays, it responds by creating melanin, which is a dark substance that is meant to keep the body from taking in too many harmful sunrays, which can damage your skin. The sun produces two different types of harmful rays: UVA and UVB. You’ll find that UVB rays are shining down on you all year round, whereas UVA rays are present in warmer weather only. Although UVA rays are considered to be the safer of the two, they can still cause damage to the skin. In fact, both types of rays can be harmful if exposed to large quantities. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ Effective use of sunscreens will not only limit extrinsic skin ageing but will also reduce skin cancer risk.
