If you use sunscreen and have a minimal amount of skin damage, you\u0026#39;ll probably see results faster. Other factors that determine how soon you\u0026#39;ll notice a change include your age, the concentration of the serum you use and how consistent you are with application. A poor diet, excessive alcohol, smoking or using narcotics slows the process.

Oxidation of the product causes it to expire faster, so avoid putting it in direct sunlight or exposing it to air or humidity. If you are unsure of how fast you\u0026#39;ll use a bottle, choose the smallest size first. This way, you can judge how fast you run out of the product and whether you should purchase a larger bottle next time.Does Vitamin C Serum Have Any Negative Side Effects?If you have sensitive or dry skin, the L-ascorbic acid in the serum can cause redness and irritation.
