Today, we will discuss the topic of sun protection, especially tips for selecting sunscreen and how to use sunscreen products correctly. Regardless of your skin type, understanding the importance of sun protection can make your skin healthier and more beautiful.
The choice of sunscreen products mainly falls into two categories: physical sunscreen and chemical sunscreen. The principle of physical sunscreen is like putting a layer of clothing on your skin; its main ingredient is titanium dioxide, which reflects sunlight and prevents UV damage. In contrast, chemical sunscreen relies on chemical ingredients that penetrate the skin to absorb UV rays. However, the sensory experience of these two types of sunscreen is quite different.
If you have sensitive or acne-prone skin, it is recommended to choose physical sunscreen. Although physical sunscreen can feel heavier upon application, its relatively gentle formula is more friendly to sensitive skin. While chemical sunscreen tends to feel refreshing, it can easily cause stinging or allergic reactions, so caution is advised when using it.
When using sunscreen products, there is one key point to note: physical sunscreen does not need to be applied in advance, whereas chemical sunscreen should be applied 30 minutes beforehand to allow the skin to effectively absorb the ingredients for optimal protection.
On the other hand, light stability is also a crucial factor when choosing sunscreen products. Chemical sunscreen ingredients usually have better light stability, but they need to be reapplied regularly to maintain effectiveness. Physical sunscreen, on the other hand, can continue to be effective without sweating and is not easily rendered ineffective.
Many people have questions about products with ultra-high protection. In fact, SPF 30 sunscreen is sufficient to provide about 90% UV protection, while SPF 50 offers about 97%. SPF 30 sunscreen is gradually becoming harder to find in the market. Therefore, if you can find a non-irritating, refreshing SPF 30 sunscreen, it would be an ideal choice. When purchasing, remember to carefully check the ingredients and select the product that best suits you.
Some may also ask whether an additional primer is necessary. Actually, sunscreen itself already provides good isolation. If you have dry skin, you might feel some discomfort after applying sunscreen, so you might consider applying a layer of hydrating hyaluronic acid serum first to reduce the burden on your skin. For most oily skin types, sunscreen alone is usually sufficient without the need for excess products.
Lastly, remember to regularly replace your sunscreen, especially those kept in the car, as high temperatures and sunlight can degrade the active ingredients and reduce their protective effects. It is recommended to use it within three months to ensure its efficacy.
I hope these tips help everyone choose the right sunscreen, protect their skin from UV damage, and achieve healthy, radiant skin!
