Why does applying sunscreen still cause skin to age, darken, and lose collagen?

Not only in the summer, dermatologists advise us to apply sunscreen regardless of whether we go out or just stay indoors all day. When exposed to sunlight for a long time, UV rays will penetrate the dermis layer of the skin, reducing collagen, making the dermis layer of the skin thinner, gradually becoming loose due to loss of elasticity, and over time wrinkles. Blue light from phones and computers can also cause skin to age faster.

The importance of sunscreen for skin is known to everyone

As you know, sunlight contains harmful UV rays. Direct contact with skin will cause consequences such as; dark spots, melasma, freckles, aging… Specifically:
● UVA rays have a wavelength of 400-315nm. They will affect the dermis layer of the skin and cause a number of skin problems such as dermatitis and skin cancer.
● UVB rays have a wavelength of 315 – 280nm. If not carefully shielded, your skin will darken, causing melasma and freckles to appear on the skin.
Therefore, applying sunscreen plays an extremely important role in your daily skin care routine.

Common mistakes that make you use sunscreen every day but still darken and age as usual

Only apply sunscreen once a day

In fact, many people only apply sunscreen once a day, in the morning before going out. In fact, sunscreen only remains effective for a certain period of time and this depends on the SPF index. Specifically, 1 SPF is equivalent to 10 minutes of sunscreen protecting the skin under sunlight. So if you use sunscreen with SPF 30, it means it can protect the skin for a maximum of 5 hours. According to experts, you should reapply after about 2-3 hours to best protect your skin.

Applying too little sunscreen

The amount of sunscreen applied is not enough, not reapplying after a period of use causes the cream to lose its effectiveness. Normally, the amount of sunscreen needed for facial skin is 2-3 ml (this level is equivalent to about 5 beans). When applying to the body, a large amount of sunscreen is needed, perhaps the size of a small cup of wine.

Do not remove makeup after using sunscreen

Not removing makeup or removing makeup poorly at the end of the day will allow the sunscreen layer to accumulate dirt and impurities, causing dull skin.
