SPF rescues rescues not only from ultraviolet, but also from aging.

When it comes to the choice - physical or chemical formulas - it becomes uneasy. Because they protect the skin in different ways, writes Women's Health.

Chemical sunscreens are absorbed into the skin layers, absorb the sun's rays and convert them into heat released by the body. Physical blockers just lie on the skin and reflect the sun's rays.

Sometimes physical compounds are called " Usually they include zinc oxide and titanium dioxide.. Chemicals are based on carbon-based organic compounds: oxybenzone, avobenzon, octinoxate and octisalate.

Although both chemical and physical protect against UVA and UVB rays, they vary in duration of protection.. Chemicals “decompose” faster when exposed to ultraviolet radiation compared to physical. However, recently manufacturers have added stabilizing ingredients to them to make up for this shortcoming..

Another important point to consider is “responsiveness”. Because physical sunscreens contain active mineral compounds, they provide instant protection. Chemical needs to be applied 20-30 minutes before sun exposure.

Physical formulas are more attractive even if the skin is too sensitive:

they need fewer ingredients to achieve a wide spectrum of action than chemical. And the poorer the composition, the lower the risk of irritation.

But if you plan to spend hours playing beach volleyball or swimming in the sea, you should prefer a chemical sunscreen. It absorbs well into the skin and is more difficult to wash off..

Physical and chemical sunscreens can be used together.. Or buy a product that combines both of these ingredients.
