Talk About Game-Changing with a 4.9 Star Rating

  • "I really love the application of this product! A little goes a long way. In addition to my face, I’m able to cover most of my neck. Have seen a marked improvement in my melasma. Better results than I ever saw using Skinceuticals CE Ferulic (I also don’t smell like a hot dog ).

  • "They are very gentle and have a velvet smooth feel on the face. Normally, I am sensitive to Vitamin C that I have used but this one doesn’t irritate my skin. I have a skin disease that gets irritated easily. There is plenty of product in the capsules. I use on face, neck and the remainder I rub into my hands. The capsules are great in being biodegradable too. Win win."

    DEBBIE R.

    Age Range: 55-64 | Skin Type: Sensitive

  • "I tried many different vitamin c serums in my life. From very expensive to less expensive. My skin has never looked better with Common Heir's vitamin c serum! The serum feels very luxurious and keeps my skin hydrated without clogging pores. It doesn't make my skin oily and it gives me a really nice glow that lasts all day. This is my go-to and I 100% recommend this serum to anyone."

    Age Range: 25-34 | Skin Type: Combination

  • "I absolutely love this product. Best Vitamin C I have ever used–my skin feels so smooth and silky. The packaging is gorgeous too–I reuse the tubes to hold bathroom essentials. It's sustainable and uses zero plastic as well."

    SEMIRA C.

    Age Range: 35-44 | Skin Type: Combination

  • "I am a very happy customer of the Vitamin C serum! In full transparency, at first I wondered if it was too oily for my face -- but I experimented and let the serum set and sink into my skin for an extra minute. Now I am HOOKED. It feels like a really rich recovery for my skin, it's the perfect amount of moisture. I formerly used a Skinceuticals serum but I prefer Common Heir now"
