Great vitamin B serum
This hydrating serum contains vitamin B (B3 niacinamide and B5 panthenol / pantothenic acid), an antioxidant that nourishes skin and treats several signs of ageing. It's also filled with pineapple ceramides, a lentil-apple-and-watermelon complex, and other nourishing ingredients. Regular use results in smoother, plumper, and brighter skin. The serum works very well for my dry skin, doesn't pill with other products, is scentless, has a great consistency, and is fantastic to mix with other DE products into "smoothies" instead of layering. Will continue using it in my winter routines / colder months, when I use DE products the most. [Edited]
