Does using a vitamin C serum have side effects?Updated a year ago
One of the best things about vitamin C serum is that, if it’s properly formulated, it's safe for all skin types and rarely causes irritation.
That said, before you introduce new products into your routine, we always recommend spot testing, especially if you have sensitive skin. Apply the product to a small area of your skin to see how it reacts before applying it to your entire face. You can also introduce vitamin C into your skin gradually, only using it every other day, and then slowly increase frequency as your skin adjusts to it.
