Vitamin C: Common Mistakes When Choosing Cosmetics

Sure! Here’s the translation:

In the realm of cosmetics, vitamin C stands out as a fundamental component due to its multiple skin benefits. Experts in the field, such as Patricia Garín, dermocosmetic director of Boutijour, emphasize its important role as an antioxidant, which not only protects the skin but also promotes the production of collagen and elastin, contributing to firmness and reducing signs of aging. However, it is essential to consider certain aspects when choosing products that contain this active ingredient.

One of the most critical factors is the percentage of vitamin C in the product. Mireia Fernández, dermocosmetic director of Perricone MD, warns that concentrations below 10% may not be effective, as they fail to penetrate cells adequately. Additionally, if vitamin C appears near the end of the ingredient list, its effect may be minimal, serving more as a preservative than an active ingredient.

The form in which the product is presented is also crucial. Vitamin C is sensitive to light and air, which can compromise its efficacy. Estefanía Nieto, dermocosmetic director of Medik8, highlights the importance of choosing packaging that provides an airtight seal to prevent oxygen and bacteria from entering. Similarly, Raquel González, a cosmetologist and creator of Byoode, mentions that the color of the product can indicate its condition; any noticeable change in hue can be a sign of oxidation.

Analyzing the ingredient list is another vital point when selecting a cosmetic. The exclusive presence of ‘Ascorbic Acid’ may indicate an unstable product. In contrast, derivatives such as Magnesium Ascorbyl Phosphate and Sodium Ascorbyl Phosphate are recommended as they are more stable and less irritating for the skin.

The choice of where to buy should also be considered carefully. Experts advise purchasing products from official or authorized retail points, as excessively low prices may be related to products nearing their expiration date.

Finally, while social media might popularize tests to evaluate the effectiveness of vitamin C—such as the reaction with Betadine—experts caution that these methods are not reliable indicators of product quality.

For those seeking recommended options, some of the standout products include Brightening Sprouts Ecstasy from Byoode, which blends several stable derivatives; Photo-Brightening Moisturizer from Perricone MD, enriched with antioxidants and anti-aging ingredients; and C-Tetra Advanced from Medik8, which contains 20% stabilized vitamin C, clinically proven and designed to brighten the skin without compromising its health. These alternatives promise not only visible results but also help protect the skin from premature aging.
