We believe that "O HUI - Day Shield Perfect Sun Stick" can provide reliable sun protection based on the ingredients listed. We love that it can protect from both UVA and UVB rays (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).
Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.
This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. Here are the exact UV filters in this sunscreen: tinosorb s 1.00% - 1.50%, uvinul a plus 2.40% - 3.60%, octinoxate 3.70% - 5.50% and octocrylene 3.00% - 4.50%.
We assess the overall irritancy of it to be high. For a detailed overview of all potential irritants: click here

This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).
