Product summary

Based on the ingredients included, we believe that "Hello Sunday - The One That's a Serum SPF 50 Hydrating and Brightening Vitamin C Serum" can offer reliable sun protection. 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).

As a plus, this sunscreen uses some of the new generation UV filters (Tinosorb M). These filters are more stable and more gentle on the skin.

It also works as a moisturizer, so you do not have to use an additional hydrating product. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

Sunscreen filters

This is a so-called "chemical" sunscreen. It means that it uses organic UV 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: tinosorb s 2.50% - 3.10%, avobenzone 1.70% - 2.00%, butyloctyl salicylate 6.80% - 8.30%, uvinul a plus 3.60% - 4.40%, uvasorb heb 1.40% - 1.70%, octisalate 3.20% - 3.90%, uvinul t 1.10% - 1.40% and tinosorb m 0.70% - 1.05%.
