UVA VS UVB
UVB damages the outermost layers which can cause tanning, sunburn and often linked to the development of skin cancer.
UVA causes genetic damage to cells in the innermost part of the upper layer of the skin, where most skin cancers occur; it also leads to premature aging and skin cancer.
MINERAL SCREEN VS SOLAR FILTER
Mineral sunscreen reflects the sun's rays as a barrier, it is commonly called mineral sun protection.
The sunscreen is a chemical sunscreen that absorbs UVA and UVB rays a bit like a sponge and filters to reduce their impact.
We are seeing more and more sun protection combining chemical and physical protection to ensure optimization of protection against UVA and UVB.
FPS 08 VS FPS 100
SPF in no way indicates its UVA protection factor. SPF 30 blocks about 97% of UVB rays while SPF 50 blocks about 98% of UVB rays.
Beyond SPF 50 protection, it is more of a good move in marketing rather than in effectiveness.
It is especially essential to check that your protection also offers UVA protection!
We are talking about broad-spectrum protection. Also keep in mind that the rays can never be completely filtered, which is why it is important to reapply sun protection every two hours.
CHEMICAL VS MINERAL
To help you know whether you are using chemical or mineral protection, here are some examples of commonly used ingredients.
Chemical:
- Avobenzone
- Octocrylene
- Homosalate
Mineral:
- Zinc oxide
- Titanium dioxide
