Anessa Gold Bottle Sun Protection Index Do you really know how to read the sun protection index?

How to read the sun protection index of Anessa Gold Bottle? Although the sun protection index of the Anessa small gold bottle is marked on the front of the bottle, many young ladies said that they could not understand the two numbers SPF and PA at all. So how do you interpret the sun protection index of the Anessa gold bottle?

Anessa Gold Bottle SPF

The sun protection index of Anessa Gold Bottle is SPF50+ , and the additional UV protection effect is PA++++ .

SPF : It indicates the protection time of medium-wave ultraviolet rays (UVB). The higher the value, the longer the protection period. In the industry, SPF50+ sunscreen is already a sunscreen with very good sun protection effect.

PA : refers to the product's protection against long-wave ultraviolet rays (UVA). The degree of protection of PA is indicated by a + sign, and the PA++++ of Anessa Gold Bottle means it is very effective.

Note: UVB is medium-wave ultraviolet light, which can be blocked by ordinary glass and is mainly absorbed by the epidermis, which can cause sunburn and sunburn (symptoms such as erythema and edema will appear after exposure to the sun).

UVA is long-wave ultraviolet light. UVA exists in all regions all year round, and 80% of UVA can penetrate the upper dermis, act on blood vessels and other tissues, and can be absorbed by melanin, hemoglobin, and bilirubin in the dermis. Can cause tanning and aging.

Judging sun protection by SPF is not scientific

Many sunscreen products with SPF50 indicated in the sun protection index are not as effective as Anessa. Therefore, it is not so good to judge the sun protection effect simply by the sun protection index. This is because indicators such as SPF and PA+ are theoretical indexes and are greatly affected by the formulation conditions. The Anessa gold bottle is equipped with the black technology of anti-friction, waterproof and sweat-proof, which is more powerful in sun protection than general products marked with SPF50. In addition, each type of sunscreen product uses different sunscreen agents (UV absorbers, UV reflectors, biological sunscreens), controls different sun protection bands, and has different absorption rates and stability after exposure to light. The formula of Anessa Gold Bottle is very stable even under the sun, providing the skin with ultra-complete protection against UVA and UVB.
