The star ingredient of Hims Morning Glow Serum is Vitamin C, which helps limit UV damage and skin discoloration. Other key ingredients include Hylauronic Acid, to moisturize the skin and protect it from free radicals, and Orange Peel Extract, to restore elasticity. This product has not been tested on animals and is 89.6% natural. Unfortunately, this serum doesn’t include any SPF, so if you’re particular about that, it might be best to look for an all-in-one option.
