防晒霜功效和作用
关于防晒霜的功效和作用,很多人对其概念还仅仅停留于“防晒黑”层面。但其实,防防晒霜所抵御的是阳光中的紫外线,而紫外线对肌肤的伤害,除了令肌肤变黑,更有甚者还会加速肌肤老化,损伤肌肤屏障。所以说,防晒霜的功效和作用不仅是为了保持颜值,更是为了呵护我们的肌肤健康,所以我们在日常挑选防晒产品时,理应更加严谨。
阳光中的紫外线,会让皮肤产生老化、炎症,进而导致泛红、色斑、肤色变黑、加速皮肤出油甚至长痘等一系列问题。而防晒霜的功效和作用,就是帮助我们的肌肤更好地抵御紫外线对肌肤的侵害,其重要性不言而喻。
虽了解防晒霜的功效和作用,但若想做好日常的防晒工作,还得选到一款适合自己的防晒霜。我们平常在挑选时,可以依据自己的肤质、防晒霜的成分与肤感进行筛选。简单来说,若你是易泛红的干皮,那么在挑选时,就应当选择成分温和,且可以滋润肌肤的防晒霜。例如仙妮蕾德爱莲润肤防晒乳液,就是不错的选择。
这款防晒中使用的成分都较为温和,就算是易泛红的脆弱肌肤,也可安心使用。其次,仙妮蕾德爱莲润肤防晒乳液的质地很清透,且拥有大大的延展性。涂抹上脸便会迅速成膜,但并不会拔干,反而可以持久地润泽肌肤。
所以在明晰防晒霜的功效和作用之后,我们还需做到正确挑选防晒霜。当然,我们日常防晒也不能仅仅依赖于防晒霜这种化学防晒,可以同时搭配防晒衣、遮阳伞此类物理防晒,双管齐下,效果更好。

1.防止紫外线辐射
臭氧层是保护我们地球的盾牌,随着臭氧层变薄,您很容易受到紫外线的不利影响,尽管阳光可以为您的身体提供维生素D,但您仍需要使用防晒霜来保护皮肤免受紫外线的伤害,防晒霜可以防止紫外线进入皮肤,预防皮肤问题。
2.避免过早老化
防晒霜可以保护皮肤免受到细纹和皱纹等衰老迹象的侵害,从而使您的皮肤看起来年轻,容光焕发,更健康。
3.减少晒伤的风险
防晒霜帮助您的皮肤,预防晒伤、晒黑。当被晒伤时,您的皮肤容易受到紫外线引起的脱皮、发红、皮疹和瘙痒的影响。
4.预防皮肤黑斑
您应该每天涂防晒霜,以防止出现黑斑、黄褐斑、雀斑和不舒服的红斑,防晒霜的作用还可以帮助您预防痤疮的发作。
5.代替粉底霜使用
防晒霜可以是化妆品的替代品,因为它既可以保护您的皮肤免受阳光照射,又可以让您的皮肤整日保持水润、亮泽。
防晒有什么作用?
防晒霜具有防嗮作用。
防晒霜添加了能阻隔或吸收紫外线的防晒剂来达到防止肌肤被晒黑、晒伤。根据具体的SPF或PA值,以达到防晒的目的,其作用原理是将皮肤与紫外线隔离开来。
扩展资料:防晒霜物理防嗮利用防晒粒子,在肌肤表面形成防护层,反射紫外线中可能对肌肤产生伤害的光波,达到保护肌肤的目的。物理防晒的粒子一般停留在肌肤表面,不会被肌肤吸收,所以对肌肤造成的负担比较小,也不容易造成肌肤敏感。化学防晒通过某些化学物质和细胞相结合,在细胞受损之前,先将紫外线中可能对肌肤产生伤害的部分吸收掉,以达到防晒的目的。
