The Importance of Sunscreen for Protecting Skin Health and How to Use It Properly

Using sunscreen is important not only in summer but throughout all four seasons. To protect skin health, let’s look at why using sunscreen matters and how to use it properly.

Ultraviolet rays are divided into UVA and UVB. UVA penetrates deep into the skin and is a major cause of wrinkles and aging, while UVB affects the skin’s surface and can cause sunburn and skin cancer. Therefore, using sunscreen is an essential way to protect skin health over the long term.

The level of protection provided by sunscreen can be identified through the SPF and PA ratings. SPF indicates the degree of UVB protection, and the higher the number, the longer it can protect the skin. PA refers to UVA protection, and the more '+' signs it has, the higher the protection effect. When going বাইরে, you should choose a product with appropriate SPF and PA ratings for the situation.

To use sunscreen properly, remember the following points. First, apply it sufficiently 15 to 30 minutes before going out. This is because sunscreen needs time to absorb into the skin. Second, reapply every 2 to 3 hours. In particular, if you sweat a lot or go swimming, you need to reapply frequently to maintain its effectiveness. Third, it is important to apply it carefully not only to the face but also to the neck and behind the ears. These areas are easy to miss but are also more likely to be exposed to sunlight.

Lastly, it is also important to choose a sunscreen that suits your skin type. For dry skin, it is good to choose a product containing moisturizing ingredients, while for oily skin, it is better to choose a fresh, lightweight type. If you have acne-prone skin, it is advisable to choose a product labeled non-comedogenic.

Because skin is difficult to recover once it has been damaged, careful daily care is necessary. Using sunscreen consistently can help prevent skin aging and reduce the risk of skin cancer. Do not forget to use sunscreen, the simplest yet one of the most effective ways to maintain healthy skin in everyday life.
