Which one should be applied first, sunscreen or foundation? Correct steps for using sunscreen

Summer has arrived, and it's time to apply sunscreen. But if you go out and put on makeup, should you apply sunscreen or foundation first? What are the correct steps to use sunscreen?

Foundation is applied after sunscreen.

Generally, sunscreen needs to be absorbed by the skin to effectively prevent UV damage. If you apply isolation cream first, the effect of the sunscreen will be weakened. The main function of isolation cream is to prevent the skin from being damaged by air, dust and makeup. It can only play its greatest role when applied on the outermost layer.

Cleanse with a facial cleanser suitable for you and pat dry with a towel.

Apply toner, because most sunscreens absorb water, so hydration is very important!

Use your hands to gently apply the essence on your face and massage moderately to allow the essence to be fully absorbed

Use your hands to gently apply the eye cream to the eyes and allow it to be completely absorbed. It is important to protect the eyes because they are weak.

Squeeze the lotion into your palm and rub it gently before applying it to your face to achieve the best moisturizing effect.

Apply an appropriate amount of cream and rub with your fingers until absorbed

Finally, apply sunscreen. Remember to apply sunscreen from the center of the forehead to both sides, evenly, and do not rub in circles, because sunscreen is not a skin care product, you do not need to rub it into the skin to let it absorb. Apply the face gently from top to bottom, do not rub from bottom to top or in circles.

Sunscreen is divided into two types: physical protection and chemical protection. The former is like a protective film on the skin to reflect ultraviolet rays, while the latter achieves the purpose of sun protection by absorbing sunlight. Chemical sunscreen lasts for a shorter time, but it will not turn white. So if your sunscreen turns white, it can be judged as physical sunscreen.

Whether it is sunscreen or sunscreen spray, it must be tested to measure the radiation protection factor inside, which is SPF. SPF is the sun protection factor. SPF1 has a sun protection of 15 points. The higher the score, the longer the protection against ultraviolet rays.

There is another term to remember, which is PA. PA prevents light from reaching deeper layers of the skin, causing spots and wrinkles. PA+ is equivalent to 4 hours of sun protection. If you want to prevent aging, you should use PA+2 times or PA++4 times to double the effect.

Therefore, when buying sunscreen, you must choose one that has both an SPF index and a PA index. Generally, you can use SPF15-30 PA++ sunscreen when going to school or work. When going to the beach or outdoor activities, you should apply SPF50 PA+++ sunscreen, and try to apply a thick layer. Of course, you can also choose a sunscreen product based on the intensity of ultraviolet rays indicated by the weather forecast for the day.

First of all, sunscreen plays an auxiliary role in blocking ultraviolet rays to prevent sunburn and tanning, but it does not have a whitening effect. If your skin is not white, it will not become white by applying this.
