Firstly, let's remember that there's no such thing as "safe tanning" and extensive sun exposure is one of the main factors contributing to premature aging. Thus, you should always wear sunscreen, even if you tan easily and quickly.
It can be easy to assume that purchasing cosmetics with SPF is sufficient, but this may not provide adequate protection. For example, to get the best protection from foundation cream, you'll have to apply a lot of it. So, it's best to use special sun protection products
There are two types of sun rays: UVB rays that affect the skin surface, causing burns and tanning, and UVA rays that affect the deep layers of the skin, damaging cells.
Out of the entire radiation spectrum, only 5% is made up of the first type of rays, while the second type, which is the UVA rays, makes up 95% and poses the greatest risk.
UVA starts the photo-aging process and provokes the emergence of malignant skin diseases. That's why quality sunscreen should protect your skin against both UVA and UVB rays.
When choosing a sunscreen, look for not only "SPF" (UVA protection) but also the abbreviations "PPD", "PA/PA+", Broad Spectrum A/UVA, or the UVA symbol in a circle on the product packaging.
American dermatologists recommend choosing
sunscreens with SPF 30-50.
The things that provide direct protection from the sun are known as sun filters. They come in two types:
- physical (mineral) - titanium dioxide, zinc oxide
- chemical (also called organic). Here you can find a complete list of these filters
Products with physical
filters are usually thicker in texture, give a whitish tint to the skin, and are better suited for sensitive skin as they are less likely to cause irritant reactions. If you have oily and problem skin, you will probably be more comfortable with physical filters - they leave a matte finish on the skin for a long time.
The drawbacks of sunscreens with physical filters are that they must be renewed every 2-3 hours and rinsed off with a hydrophilic cleanser.
