What colour ought to Vitamin C Serum be?

Vitamin C is derived from oranges so it is smart that it will flip yellow, proper? In actuality, Vitamin C dissolved in water is completely clear. An orange-tinted serum is definitely not factor in any respect!

In a 2018 interview with picture.ie dermatologist Dr. Rosemary Coleman mentioned:

“Vitamin C has quite a complicated chemistry, and because it’s a water-soluble vitamin, it becomes very unstable in water solutions.

Will utilizing a discolored serum damage my pores and skin?

However in the event you bought unfortunate and have a transparent bottle, make sure that that is stored in a drawer away from daylight. You would additionally cowl the glass with a sticker or tape, however I do know I personally don’t wish to mess up the producer label in case I wish to verify one thing sooner or later.
