How we score →Yay
6 experts · Moderate agreementWhat the gurus are saying
The 10% strength is the detail that keeps coming up, and it is seen as the gentler start for sensitive skin or anyone new to vitamin C. Vitamin E and ferulic acid help stabilize the vitamin C, and the serum is praised as an affordable alternative to pricier serums. The 20% version is stronger, so those new to it may want to start with the 10%.

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.
