Product summary

"Kiehl's - Facial Fuel SPF 20" "is a broad spectrum sunscreen meaning that it protects both from UVB rays (" burning "- they cause sunburn) and UVA rays (" aging "- they don't cause sunburn but lead to premature aging and pigmentation issues). However, this sunscreen does not offer enough sun protection. We recommend to use a sunscreen with at least SPF 30 daily.

Its formula is also hydrating, so you might not need an additional moistruizer during the day.
