This product contains antioxidants (chrysin) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: helianthus annuus seed oil, carthamus tinctorius seed oil.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Product summary

Based on the ingredient list, we assess that "O HUI - Day Shield Sun Stick" can provide reliable sun protection. 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).

It should also be hydrating enough to use without an additional moisturizer during the day. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

Sunscreen filters

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. These are the sun protection ingredients 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%.
