Caused slight stinging/burning when applying sometimes, although no noticeable redness or irritation afterwards. Unsure why it did this for me since I've used these type of ingredients before without issues. Not nearly as hydrating as I would like for an nighttime product.
Cheaply made packaging and bottles. The pumping mechanism kept breaking before I got to finish the product, which was annoying.
Results were lackluster. I didn't really see any difference even after using this for about 2 months. Overall, very disappointing.
