By Wishtrend Pure Vitamin C SerumBy Wishtrend Pure Vitamin C 15% with Ferulic Acid
Q. Are the By Wishtrend pure vitamin C serums dermatologist-approved?
Q. I heard that vitamin C becomes less stable and potent when paired with water. Are the By Wishtrend vitamin C serums formulated with water, and if so, does this make them less effective?
Q. My By Wishtrend Pure Vitamin C 15% with Ferulic Acid came with a loose cap. Did I receive a faulty product?
Q. I read that the ideal pH for vitamin C serums ranges from 2 - 3.5. Does the By Wishtrend Pure Vitamin C serums have a pH level higher than this?
Q. Is the Pure Vitamin C 15% with Ferulic Acid formulated with L-ascorbic acid or a vitamin C derivative?
Q. What precautions should I take into consideration before using the Pure Vitamin C 21.5% Advanced Serum?
Application: Avoid sensitive areas surrounding the eyes and mouth, as well as open wounds. If you’re a first time user, you may experience a slight tingling sensation which is a natural phenomenon caused by the pH difference in the skin and vitamin C.
Ingredients to Use/ Avoid: Should you choose to use the serum during the morning, make sure to follow up with a sunscreen with an SPF of 15 or higher before leaving the house. Because vitamin C possesses mild exfoliative properties, we recommend avoiding using both physical and chemical exfoliators on the same day as the vitamin C serum,
Storage: Vitamin C naturally oxidizes over time and is especially sensitive to air, light and temperature change. As this product contains high concentrations of pure Vitamin C, it’s best when used immediately after purchase for maximum effectiveness.
Q. I thought 20% is the maximum percentage that vitamin C is effective. Why does the By Wishtrend Pure Vitamin C 21.5% Advanced Serum contain more than 20% vitamin C?
