About this sunscreen
RyxSkin Sincerity Sunshield SPF 50+++ is a chemical (hybrid) sunscreen mixing Octinoxate, Octocrylene, Avobenzone and Tinosorb S with Titanium Dioxide and Zinc Oxide. It has a balanced finish but tends to leave a visible white cast, feels moderately heavy and is a poor base under makeup. The pore-clogging profile is low. The SPF 50 gives good protection, but with a score of 59.3 out of 100 the noticeable cast, heavier feel and possible stinging keep it a middling option.

Does RyxSkin Sincerity Sunshield leave a white cast?
Yes, its white cast is rated high, so it can leave a visible whitish layer, especially on deeper skin tones. The mineral content in the hybrid formula contributes to this.
Is RyxSkin Sincerity Sunshield good under makeup?
It rates as a poor base under makeup and feels moderately heavy, so it does not layer ideally beneath foundation. It is better worn on its own.
Is RyxSkin Sincerity Sunshield SPF 50 good?
It scores 59.3 out of 100, a middling result. The SPF 50 gives good protection and pore-clogging risk is low, but the visible white cast, heavier feel and possible stinging hold it back.
