Increasing evidence on the impact of the different wavelengths of sunlight on the skin demonstrates the need for tailored recommendations of sunscreen according to skin phototype and dermatoses, which is now possible due to advances in the filters and formulations of sunscreens. A selective literature search was performed by an international expert panel, focusing on the type of sunscreen to recommend for photoaging, skin cancers, photodermatoses, pigmentary disorders and skin inflammatory disorders. Protection against ultraviolet (UV)B is especially important for light skin as there is a high risk of sunburn, DNA damage and skin cancers. Darker skin may be naturally better protected against UVB but is more prone to hyperpigmentation induced by visible light (VL) and UVA. Protection against UVA, VL and infrared A can be helpful for all skin phototypes as they penetrate deeply and cause photoaging. Long-wave UVA1 plays a critical role in pigmentation, photoaging, skin cancer, DNA damage and photodermatoses. Adapting the formulation and texture of the sunscreen to the type of skin and dermatoses is also essential. Practical recommendations on the type of sunscreen to prescribe are provided to support the clinician in daily practice.
越来越多的证据表明，阳光中不同波长对皮肤的影响需要根据皮肤光型和皮肤病来定制防晒霜的建议，这在如今由于防晒霜的过滤和配方的进步成为了可能。一个国际专家小组进行了选择性的文献检索，重点是针对光老化、皮肤癌、光皮病、色素紊乱和皮肤炎症性疾病推荐的防晒霜类型。对于浅色皮肤来说，防止紫外线（UVB）的伤害尤为重要，因为它们有很高的晒伤、DNA 损伤和皮肤癌风险。深色皮肤可能天然对 UVB 有更好的保护，但更容易受到可见光（VL）和 UVA 引起的色素沉着。防止 UVA、VL 和红外线 A 对所有皮肤光型都有帮助，因为它们能深入穿透皮肤并导致光老化。长波 UVA1 在色素沉着、光老化、皮肤癌、DNA 损伤和光皮病中起着关键作用。根据皮肤类型和皮肤病来调整防晒霜的配方和质地也至关重要。本文提供了有关处方防晒霜类型的实用建议，以支持临床医生的日常实践。
