The mechanism of action, the effect of sunscreen and how to use it to avoid the sun effectively
1 How does sunscreen work? Sunscreens work in two categories with different mechanisms. The former mostly contain zinc oxide (ZnO) or titanium dioxide that bounces UV light. The latter can block UV radiation with chemical filters such as octisalate, oxybenzone , avobenzone, homosalate, octinoxate and octocrylene. Chemicals such as retinoids (a form of Vitamin A) found in sunscreens can slow down the aging process of the skin, which in turn reduces the risk of developing skin cancer or the development of lesions and tumors when exposed to sunlight. In particular, the ingredient zinc oxide has been shown to be safe and effective to block UVA and UVB rays . Currently, some brands have used zinc oxide in their products to prevent UV rays. However, you should not choose sunscreens containing nano zinc oxide because of the risk of toxicity. 2 Effects of sunscreen Prevent UV radiation: Sunscreen minimizes the level of damage to the skin, prevents UV radiation from pe...
