We love vitamin C. It’s one of two ingredients (the other is retinol) that nearly every dermatologist we’ve ever spoken to agrees is effective at addressing all sorts of skin woes, from dullness to dark spots. That said, how it’s formulated is very important, since vitamin C tends to oxidize quickly, which affects its potency.
This is one of the key reasons behind Common Heir’s decision to ditch the pumps and bottles that usually house the ingredient and opt for single-use capsules instead. Each capsule is packed with 10 percent vitamin C that you access by twisting off the top and squeezing to release a day's worth of fresh serum onto your face and neck.
Also of note: The plant-based capsules are completely biodegradable and can either be tossed in your trash or melted down in hot water; plus, all of the shipping materials—including the cute container the capsules come in—are fully and readily recyclable.
