The Ordinary Niacinamide 10% + Zinc 1% carries a Guru Score of 69% from 27 independent experts.

What do the experts say about Watermelon Glow Niacinamide Dew Drops?
Glow Recipe Watermelon Glow Niacinamide Dew Drops carries a Guru Score of 68% from 21 independent experts. This dew drops serum delivers a noticeable, immediate glow that works beautifully as a primer or layered into skincare, though opinions split on whether the effect justifies the price and the formula's thickness. Dermatologists and skincare experts praise the niacinamide and hyaluronic acid for genuine barrier support and calming redness, and many love how seamlessly it blends under makeup or on its own. However, it contains fragrance from natural plant extracts (under 0.5 percent), which may irritate sensitive or reactive skin, and some find the shine too intense or the texture too heavy for all-day wear. Best patch-tested first if your skin is easily triggered, and worth trying on sale.
