15 Amazon Vitamin C Serums That'll Brighten Your Skin in No Time

Ursa Major Natural Vitamin C Serum ($56)

As a B Corp, Ursa Major has some of the highest standards for crafting safe and environmentally friendly products. It's chock full of botanicals such as nourishing sunflower seed oil, rosehip extract and antioxidant-rich rosemary leaf extract. Those work with soothing aloe and moisturizing glycerin to hydrate skin and even out your skin tone with consistent use. It has no artificial fragrances, but it contains essential oils that give it a subtle rose scent. (Note that if you have sensitive skin, even essential oils can be irritating.) "I love this because it doesn't leave an oily residue on my skin like some Vitamin C products," writes a reviewer who rated it five stars. "The bottle looks nice and the serum absorbs well. The smell is fantastic and I have had great results. The price is a bit high but so is the quality. I'd recommend it."
