How we score →Yay
20 experts · Strong agreementHeads up: 12 of the 20 experts here were paid by the brand, leaving 8 unpaid. We have kept this score cautious as a result.
What the gurus are saying
A sunscreen that wears like a lotion is the whole appeal: the experts praise a dewy, hydrating finish that sinks in without grease, stinging or white cast, and sits well under makeup. Dry and easily irritated skin gets the warmest welcome. The catch is that birch is a common allergen, so go carefully if your skin reacts easily, and a couple of experts would rather have something creamier.

“It is all chemical filters but offers high protection, SPF 50 and PA++++, which is the highest level of UVA protection you can get, and also helps to improve skin texture and skin tone with the ingredients that it has.”

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.
Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
