Dr. Barbara Sturm’s THE GOOD C VITAMIN C SERUM deploys her proprietary formulation of Vitamin C in three skin-friendly forms. The serum contains the optimal concentration of 5% Vitamin C in a stable form that is easily absorbed, safe and gentle on the skin. THE GOOD C VITAMIN C SERUM has an active ingredient complex that includes oil-soluble Vitamin C THD, stabilized, synthetic Vitamin C in glucosidic form and an extract from Kakadu Plum, a fruit that is a potent source of plant-based Vitamin C. Together, they help to reduce uneven pigmentation, improve tone and provide anti-oxidative protection from free radicals and environmental stressors for a youthful and healthy-looking complexion. The serum also contains Zinc, which helps to increase the absorption of Vitamin C into the skin. Finally, Vitamin C supports the formation of collagen, which is needed for firm and youthful-looking skin.

30 mL


  • An innovative and skin-friendly serum containing three forms of Vitamin C
  • Zinc helps to activate and transport Vitamin C effectively into the skin
  • The serum has strong anti-oxidant properties, protecting against environmental stressors
  • Aloe Vera and Hyaluronic Acid provide intensive moisture and hydration
  • THE GOOD C counteracts the new formation of age spots, and helps to reduce the appearance of pigmentation
  • Regular usage results in brighter, more radiant skin


Place one pipette length of THE GOOD C VITAMIN C SERUM into the palm of your hand and distribute over the face using gentle tapping motions. Avoid the eye area. Wait for approximately one minute until the serum is absorbed before applying Dr. Barbara Sturm’s FACE CREAM. For daytime use, we recommend concluding your skincare routine with SUN DROPS SPF 50 for extra sun protection. Also suitable for use in the evening as a night-time serum. THE GOOD C VITAMIN C SERUM can be mixed with other Sturm serums, drops or moisturizers.

“I developed THE GOOD C VITAMIN C SERUM in response to clients who wanted the radiance boosting effects of Vitamin C in an optimum concentration, without damaging skin barrier function or causing sensitivity. My formulation combines the right chemistry of Vitamin C with surrounding ingredient science to boost the skin and provides antioxidant properties that protect from free radicals and daily environmental stress while combatting pigmentation. Regular usage results in a complexion that’s healthy-looking, fresh and radiant.” – DR. BARBARA STURM

    Love this!

    I am a huge fan of this serum. This might be the perfect vitamin C serum for anyone with irritable skin. I know some don't love the relatively low levels of vitamin C here but as someone with very temperamental skin, this amount is actually perfect. I've used 10%, 15%, even 20% vitamin C serums and this makes my skin happier than any of those did. The 20% especially was way too active and caused me to breakout. All other vitamin C serums I've used also would leave my face feeling sticky. This is literally the first vitamin C serum that does not do that. Instead, my skin just feels smooth and...for lack of better word, happy. It feels energized and yet calm, and just happy. I will be repurchasing this again for sure. If you have sensitive skin, this serum is a dream. Thank you for yet another beautiful product, Barbara Sturm!

    The Good C Vitamin C Serum

    This serum is lovely, comforting, refreshing, and brightening. It is great for my sensitive skin and doesn't feel tacky on the skin. It also doesn't break me out like other Vitamin C products. I love all of Dr Sturm's products and this is no exception! Amazing!

    Good C serum

    Just started using this and so far so good. Haven’t seen any improvement yet. But very hydrating and immediately penetrates skin.
