Beauticians constantly emphasize that the skin needs protection from harmful solar radiation. Moreover, it must be protected with a high-quality tool that has several filters and covers rays of a different spectrum. Do not neglect such a care product even in the spring – now the sun is active enough so that you can get a burn. We talk about in which cosmetics special chemical filters should be added.
SPF: in what cosmetics should be
UV protection helps keep skin youthful
What are the rays?
Before talking about cosmetics, you need to understand from what light radiation you need to protect the skin. There are three types of rays:
- UVA are long wavelength rays that make up 95% of the solar radiation. The main danger to the skin is premature aging. They penetrate into the deeper layers of the skin and destroy cells from the inside, causing a tan. They are especially dangerous for dry skin, which already lacks moisture. For other skin types with proper care, this type of radiation is not terrible.
- UVBs are medium-wavelength rays that make up almost 5% of radiation. They are the cause of burns, pigmentation and irritation on the skin. Their peak action occurs at lunchtime – it is not in vain that doctors advise against sunbathing from 10 to 16 hours. This type of radiation is dangerous for children, fair-skinned adults, people prone to pigmentation, and lovers of acid peels and polishes.
- UVCs are short-wavelength rays that make up hundredths of a percent. They practically do not penetrate the atmosphere, therefore they are not dangerous to humans.
UV Protection Ingredients
Conventionally, UV filters are divided into physical and chemical. The physical ones include:
- Zinc Oxide (Zinc Oxide) – protects against both types of radiation , but whitens the skin and can cause a feeling of dryness. Ideal for children and fair-skinned adults.
- Titanium dioxide – protects against UVB rays, but does not cope well with UVA. Also whitens and can clog pores. Suitable for people who rarely burn out in the sun.
- Avobenzon (Avobenzone) – absorbs UVA, but does not protect against UVB radiation. Suitable for people who sunbathe well and quickly acquire an even dark skin tone.
- Tinosorb (Tinosorb) – protects against both types of radiation . Suitable for all people, including children and fair-skinned adults.
- Octocrylene (Octocrylene) – absorbs UVB, but does not protect against UVA.
- Oxybenzone, or benzophenone (Oxybenzone) – protects only from UVA radiation.
- Octinoxate (Octinoxate) – protects only from UVB radiation.
- Ethyhexyl triazone (Ethylhexyl triazone) – active only from UVB.
What to look for when choosing a tool
- Label. The degree of protection should be indicated on it: 2-4 – protection from 50-75% of the rays, 4-10 – protection from 80%, 10-20 – protection from 95%, 20-30 – protection from 97%, 30-50 – protection against 99% of the rays. UVA protection factor is indicated by a special icon in a circle on the front of the package. Remember that the thinner the layer, the less protection – approximately 2 mm of cream will be ideal for blocking light.
- Phototype. The lighter your skin, hair and eyes, the more you are exposed to radiation. Fair-skinned people must use sun protection, and update it at least every 2 hours – during this time you sweat, bathe, touch the skin, so that the layer is gradually removed.
- Price. A good remedy cannot be cheap. Always pay attention to the composition before buying a cream or spray. The manufacturer’s promises of water resistance and durability will not matter when you lie in the shade instead of bathing because you have recently burned.
