The Hidden Costs of Vitamin C in Skincare

Vitamin C is one of the most popular ingredients in skincare products, renowned for its brightening and anti-aging benefits. However, the production and use of Vitamin C have some significant downsides that consumers should be aware of. This article delves into the hidden costs of Vitamin C, including its environmental impact and its effect on skin sensitivity.

Environmental Impact of Vitamin C Production

The production of Vitamin C (ascorbic acid) often involves synthetic chemical processes that are far from eco-friendly. The main industrial process, known as the Reichstein process, uses a significant amount of chemicals and energy, contributing to pollution and carbon emissions. This process involves the hydrogenation of D-glucose to D-sorbitol, followed by fermentation and chemical synthesis steps. Each stage requires specific chemicals and conditions that can be harmful to the environment. (Environmental Science & Technology).

Use of Non-Sustainable Resources

The raw materials for producing synthetic Vitamin C at an industrial scale typically come from non-renewable petroleum-based sources. This reliance on fossil fuels not only contributes to the depletion of these resources but also to the overall carbon footprint of the production process. Furthermore, the waste products generated during the synthesis of Vitamin C can be challenging to dispose of, often ending up in landfills or water bodies, leading to long-term environmental damage.

Increased Sun Sensitivity

One of the lesser-known effects of using Vitamin C in skincare is increased sensitivity to the sun. The articles that refute this have very small sample sizes and do not properly evaluate the effects. Vitamin C can make the skin more susceptible to UV damage, leading to sunburns and the development of sun marks (Journal of Clinical and Aesthetic Dermatology). This is particularly true when formulated at concentrations higher than 20% and without properly stabilizing ingredient. This necessitates the regular use of sunscreens, which may contain other harmful chemicals, thus counteracting the natural benefit of using Vitamin C.

Health Concerns

While Vitamin C itself is generally safe, the accompanying ingredients in formulations can be problematic. For example, some products may contain preservatives and synthetic stabilizers that can irritate the skin or cause allergic reactions. Additionally, overuse of Vitamin C can disrupt the skin's natural barrier, leading to dryness and sensitivity.

 As consumers become more aware of the impact of their skincare choices, it's crucial to look beyond the surface benefits of ingredients like Vitamin C. Opting for products that are sustainably sourced and produced can help mitigate some of these issues, ensuring that your skincare routine is both effective and environmentally responsible.
