摘要
局部应用防晒霜越来越被公众接受。大部分的防晒霜由物理防晒剂和化学防晒剂组成.可以有效地防止紫外线引起的皮肤红斑反应、免疫抑制、光老化以及皮肤癌的发生。防晒霜应有中波紫外线和长波紫外线的全面防护功能。评价防晒霜要从其吸收光谱,衰减系数,中波紫外线防护功能以及长波紫外线防护功能等方面进行考虑。
Topical sunscreens act by absorbing or scattering ultraviolet (LrV) radiation and are widely available for general public use as a consumer product. Most sunscreens combine chemical UV absorbing sunscreens and physical inorganic sunscreens. Promoting sunscreen use is an integral part of prevention aiming at reducing UV radiation-induced sunburn, immunosuppression, photoaging and skin cancers. Protection against both ultraviolet B ( UVB ) and ultraviolet A ( UVA ) radiation is desirable. To assess a sunscreen, absorption spectrum, reduction coefficient, ability of UVB- and UVA-protection should be considered.
