The 1-2-3-4 rule helps sunscreen work at 100% effectiveness!

Summer is here, don't forget that the skin's number one enemy - UV rays are always lurking. If you want your sunscreen to work 100% effectively, remember the sacred 1-2-3-4 rule, the "undefeated" secret below.

1 suitable sunscreen

Oily skin, dry skin, sensitive skin,... each skin type will have its own suitable sunscreen. Therefore, learn carefully about your skin to choose the most "matching" product, and pay attention to the SPF index (UVB protection) and PA (UVA protection) to choose the right one for your needs and outdoor activities. For example, SPF 30 and PA+++ for indoor activities, SPF 50+ and PA++++ for outdoor activities.

In addition, the texture of sunscreen (cream, gel, spray, ...) is also an important factor, choose the texture that you feel most comfortable and pleasant when using. Prioritize products with benign ingredients that do not cause skin irritation. Especially for oily, acne-prone skin, look for sunscreens with a light gel or lotion texture that does not clog pores and contains ingredients such as niacinamide or salicylic acid to control oil and reduce acne.

20 minutes: Waiting time for sunscreen to start working

People often mistakenly think that after applying sunscreen, they are "invincible" in the sun. However, the truth is that sunscreen needs time to "set-up". About 20 minutes after application, the cream will create a perfect protective layer on the skin, helping to "repel" harmful UV rays. If you rush out right after applying the cream, be careful that your skin will be "attacked" by UV rays, causing dark spots, melasma, and freckles.

3 hours: Time to reapply sunscreen

Don't be stingy with "cream" and only apply a few drops, your skin will not be fully protected, apply enough sunscreen (about 1 coin for face and neck) and reapply every 2-3 hours. Especially every 3 hours, whether you are sitting indoors or outdoors, you must reapply sunscreen. Why? Because sunscreen also has an expiration date, after 3 hours, the cream will no longer be able to protect your skin. Diligently follow these rules, ensuring that your skin will always be "healthy", "white and bright" and "not afraid of the sun".

Sunscreen is needed in all 4 seasons of the year.

Sunscreen is an indispensable skin protection product throughout all four seasons, because UV rays from the sun are always present and harmful to the skin whether it is sunny or cloudy. In the summer, UV rays are strongest, causing sunburn, darkening of the skin, premature aging, while in the winter, UV rays can still penetrate clouds, causing silent skin damage. In spring and autumn, the weather changes erratically, the skin is easily irritated, more sensitive, and needs careful protection. Using sunscreen daily helps prevent skin problems such as melasma, freckles, wrinkles, and the risk of skin cancer, maintaining healthy, youthful skin regardless of the weather.

Rejuvaskin Mineral Facial physical sunscreen moisturizes and restores skin SPF 32

Rejuvaskin Mineral Facial SPF 32 sunscreen is making waves in the skincare world recently. This is a physical sunscreen with the main ingredient being Zinc Oxide, which is famous for being benign and protecting the skin extremely well from UV rays. The cream is a bit thick, but when applied to the skin, it absorbs quite quickly, does not cause an uncomfortable greasy feeling, especially does not leave white streaks on the skin. The big plus point of this sunscreen is its ability to moisturize and restore the skin, thanks to the ingredient Niacinamide, which helps the skin stay soft, smooth and healthy. However, because it is a physical sunscreen, this product will be a bit shiny after application, but just apply a thin layer of powder and it will be fine. For those with sensitive skin or undergoing treatment, this product is a choice worth considering.
