Vitamin C turns up in both the fruit bowl and the skincare aisle. If you are wondering where it fits, it helps to separate what your body needs from what a particular product might do.
1. Vitamin C has a role in collagen formation
Your body needs vitamin C for normal collagen formation, and it contributes to wound healing. That nutrient function does not establish the effect of a particular serum. Australian nutrient reference values — Vitamin C; Pullar and colleagues — skin-health review, 2017.
2. Antioxidant activity is one part of the story
Vitamin C acts as an antioxidant. Research on that activity includes laboratory work as well as human studies, so a biological mechanism alone cannot tell you what change to expect from a skincare product. Pullar and colleagues — skin-health review, 2017.
Keep sun protection in your daily routine: shade, clothing, a hat and sunscreen used as directed work together. Healthdirect — Sun protection.
3. Pigmentation needs more than an ingredient choice
Topical vitamin C has been studied for pigmentation, but delivery into skin and differences between formulations complicate interpretation. The review does not establish that every vitamin C product gives the same result. Pullar and colleagues — skin-health review, 2017.
Start with our pigmentation guide. A new or changing spot needs a medical assessment before cosmetic treatment. Cancer Council — Melanoma.
4. Food and topical products are different choices
Capsicum, oranges, kiwifruit and broccoli provide vitamin C. The Australian recommended dietary intake for adults is 45 mg a day; pregnancy and breastfeeding have different requirements. This is a nutrition reference, not a supplement dose. Healthdirect — Vitamin C; Australian nutrient reference values.
A varied diet is a practical starting point. Discuss supplements with your doctor or dietitian if you are concerned about intake or absorption. Healthdirect — Vitamin C.
Questions to bring along
What would you like to understand about your skin? Which products do you already use? Has a clinician assessed the marks you are concerned about?
You can ask about advanced skin analysis or the dietary review included in an initial naturopathy consultation. Both are on the current menu. Melbourne Wellness — Services.
If products tend to sting, our sensitive-skin moisturiser article offers questions to start that conversation.
Discuss suitability at a consultation.
