Piping Rock Niacinamide and Zinc Serum | 2 Fl Oz | Liquid Drops Supplement | with Hyaluronic Acid | Vegetarian, Non-GMO, Gluten Free

This serum is sizable. It’s easy to use - just a drop or two and massage onto the skin. Niacinamide is great for nurturing the skin both daytime and nighttime. I use a toner first, then this serum, then lotion/cream for my routine.

I have no complaints with this serum. Of course, it takes at least a month of regular use to really gauge how successful a skin care product works. So far I like what I see. A little goes a long way. It feels good on my skin. It absorbs nicely. It's not the most moisturizing, so I always add my regular moisturizer with this product. I do notice that my skin glows a bit more. At the price point, it's definitely worth giving a try.

El producto me genera ardor al aplicarlo , otras personas lo probaron y les sucede lo mismo

May take months of application. I see no visible difference after 1 week.

No me gusto para nada y no hizo ningún efecto en mi piel.

Won't buy this product because you don't describe the ingredients and percentages, making it impossible to comparison shop.

Me encanto

Suero ligero y efectivoLlevo dos semanas usando este suero y me gusta mucho. Se absorbe rápido, no deja grasa ni irrita mi piel sensible. He notado que mis poros están más pequeños y el tono de mi piel más uniforme. El gotero es práctico y fácil de usar. Lo recomiendo si buscas un suero suave y eficaz.
