Is the logo for protecting long-wave ultraviolet rays pa or ua?

In the cosmetics industry, the symbol used to represent UVA prevention is usually PA. PA logo is formulated by Japan Cosmetics Industry Federation to show the protection ability of sunscreen products against UVA. PA logo is divided into four grades, namely, PA+, PA++, PA++ and PA++. The more+signs, the stronger the protection ability. Generally speaking, PA+++++is the highest level of UVA protection sign. UA is usually used to indicate the protection ability of sunscreen products against ultraviolet B(UVB). Similar to PA logo, UA logo is also divided into four grades, namely UVA, UA++, UA++ and UA++. The more+signs, the stronger the protection ability.

It should be noted that different sunscreen products may have different protection labels, and the specific protection ability will be different due to the composition and formula of the products. When choosing sunscreen products, you should choose sunscreen products that suit you according to your own needs and skin quality, and pay attention to the correct use and touch-up.
