Frequently Asked Questions about Powerful-Strength Vitamin C Serum:
Ingredients and Benefits
Q: What are the main ingredients of this serum? What are its benefits?
A: The main ingredient is a high concentration of vitamin C (ascorbic acid), which is usually around 10% - 15%, and the specific content may vary slightly depending on the product version. Vitamin C is a powerful antioxidant that can neutralize free radicals and reduce damage to the skin caused by environmental factors (such as UV rays and pollution), thereby preventing and improving signs of aging such as wrinkles and fine lines. At the same time, it can also inhibit the production of melanin, brighten the skin tone, reduce spots and dullness, and make the skin brighter and more even. In addition, the product may also contain moisturizing ingredients such as hyaluronic acid to help keep the skin hydrated.
How to use
Q: How to use this vitamin C serum correctly?
A: It is recommended to use after cleansing and toning. Take 3 - 4 drops of serum on the palm of your hand and gently apply to the face and neck, avoiding the skin around the eyes. You can use your fingertips to gently massage the skin to help it absorb until the essence is completely absorbed by the skin, and then proceed with the subsequent moisturizing steps of lotion or cream. It is generally recommended to use it every morning, because the skin is more vulnerable to free radicals during the day, and vitamin C can play an antioxidant role.
Q: Can it be used at night?
A: Yes. It can also play its antioxidant and brightening effects at night. However, since vitamin C may become unstable under light, you need to take sun protection measures after using it during the day to ensure its effect. When used at night, it may better cooperate with the skin's self-repair process at night.
Applicable skin types
Q: What skin types is this essence suitable for?
A: It is suitable for a variety of skin types, including dry, oily and combination skin types. For dry skin types, the moisturizing ingredients in the essence can help relieve dry skin; oily skin types can benefit from its antioxidant and brightening effects, and the product texture is usually refreshing and will not increase oiliness; combination skin types can also improve skin problems through local use when the T zone is oily and the cheeks are dry. However, sensitive skin may need to use it with caution, as high concentrations of vitamin C may cause irritation.
Stability and Storage
Q: Vitamin C is very easy to oxidize, how does this essence maintain its stability?
A: Brands often use special packaging techniques, such as dark glass bottles, to block light and reduce the oxidation of vitamin C. In addition, other ingredients in the formula may also play a role in stabilizing vitamin C, such as adding some antioxidants to work together, or using special packaging techniques to wrap vitamin C so that it is released only after contact with the skin, thereby improving its stability.
Q: How should this essence be stored?
A: It is best to store it in a cool, dry place away from direct sunlight. Make sure the bottle cap is tightly closed after each use to prevent air from entering and causing the essence to oxidize. If the color of the essence is found to darken, this may be a sign of vitamin C oxidation, which will affect its effectiveness. It is recommended to stop using it.
