Vitamin C Skincare: Your Top 10 Questions Answered

Vitamin C Skincare: Your Top 10 Questions Answered

Question 1: What are the benefits of using Vitamin C in skincare?


  1. Vitamin C is known for its antioxidant properties, which can help protect the skin from environmental damage caused by factors like UV rays and pollution. 
  2. Vitamin C plays a role in collagen synthesis, which can help improve skin's texture and firmness, thus reducing signs of aging.
  3. Vitamin C can help brighten the complexion, reduce the appearance of dark spots and hyperpigmentation, promote even skin tone, and provide a more youthful appearance.

Question 2: Do all vitamin C molecules have the same properties?

Answer: Not all vitamin C molecules possess identical properties. While all vitamin C molecules exhibit antioxidant traits, their effectiveness and anti-aging benefits can vary.

  1. Ascorbic Acid: The most effective form of Vitamin C, yet its instability can limit its effectiveness. To enhance stability and efficacy, Helwé combined Vitamin C with Vitamin E and Ferulic Acid in the Sérum Radieux
  2. Liposoluble Vitamin C (Tetrahexyl Ascorbate): A stable and liposoluble form of vitamin C highly effective in skin care. It can be used both during the day and at night, offering hydration benefits as well. This vitamin C is present in our Sérum Éclat.

Question 3: Does a higher concentration of vitamin C offer more benefits?

Answer: Not necessarily. Ascorbic acid (vitamin C) is highly effective within the concentration range of 10 to 15%. However, concentrations above 20% can lead to destabilization and a reduction in effectiveness.

At Helwé, our approach involves using a 10% concentration of ascorbic acid alongside 1% liposoluble vitamin C. In our Serum Éclat, we also use a 10% concentration of liposoluble vitamin C, which penetrates the skin twice as effectively as 20% ascorbic acid. As a result, Sérum Éclat is very effective and works for all types of skin. It can be seamlessly integrated with Hydrosoluble Serum Radieux during the evening.

Question 4: Is Topical Vitamin C Necessary for Your Skin?

Answer: Yes, incorporating topical vitamin C into your skincare routine is recommended, especially for individuals aged 28 and above. Unlike some vitamins, our bodies don't naturally produce vitamin C, making external application crucial. While dietary sources offer vitamin C, another approach involves a daily intake of 1000 mg orally. However, only about 30% of this oral vitamin C is effectively absorbed, and it may not reach the skin optimally. Hence, the use of a daily vitamin C serum is vital to ensure its direct skin benefits.

Question 5: Can Vitamin C be used in the morning?

Answer: Absolutely. Several studies indicate that Vitamin C functions as a defense against harmful UVA rays and enhances the skin's antioxidant defenses. Applying Vitamin C every morning before sunscreen (SPF) can amplify the effectiveness of the SPF itself, providing dual protection against UV damage and free radicals. Therefore, incorporating Vitamin C into your morning routine not only helps shield your skin but also boosts the benefits of your sunscreen.

Question 6: Can Vitamin C be used for all skin types, including sensitive skin?

Answer: Yes. The suitability of a Vitamin C serum depends on the specific formulation of the product it's included in. At Helwé, our serum blends ascorbic acid (Vitamin C) with soothing natural elements like aloe vera and carrot hydrosol. This formulation ensures compatibility with all skin types, promoting balance and comfort. Additionally, tetraethyl ascorbate, another form of Vitamin C, is notably beneficial for sensitive skin, catering to a wide range of skincare needs with its gentle yet effective properties.

Question 7: Is Vitamin C more effective when paired with other antioxidants?

Answer: Yes. Indeed, research reveals that synergizing Vitamin C with fellow antioxidants like Vitamin E, ferulic acid, and others leads to a notably potent effect on the skin's well-being and vitality. This harmonious blend of antioxidants is recognized for its exceptional efficacy.

Question 8: Can I use Vitamin C with other active ingredients?

Answer: Yes, Vitamin C can be used in combination with other skincare ingredients, but it's important to be cautious if you have sensitive skin. 

Question 9: Can Vitamin C reverse signs of aging?

Answer: Yes, Vitamin C can help reduce the appearance of fine lines and wrinkles by promoting collagen production  providing antioxidant protection. However, it's not a miracle cure and should be part of a skincare routine.

Question 10: How long does it take to see results with Vitamin C?

Results can vary from person to person, but many users report noticing brighter and more even skin tone within a few weeks to a couple of months of consistent use.
