Product summary

We believe that "Hawaiian Tropic - Island Sport Lotion Sunscreen SPF 50" can provide reliable sun protection based on the ingredients listed. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

It contains good moisturizing ingredients and can double as a hydrating day cream. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

Sunscreen filters

They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. Here are the exact UV filters in this sunscreen: oxybenzone 0.00% - 0.00%, avobenzone 0.20% - 0.70%, butyloctyl salicylate 0.10% - 0.45%, octisalate 4.40% - 6.60%, homosalate 4.00% - 6.00% and octocrylene 0.00% - 0.00%.

At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores.
