Usage of Stabilized Vitamin C (Natural-C Glycol™) Serum

Regarding the Stabilized Vitamin C (Natural-C Glycol™) Serum, it can be used both in the morning and at night.

Vitamin C itself does not make your skin more sensitive to light. However, exposure to sunlight can counteract the brightening effects of Vitamin C.

Typical fluorescent lighting found in offices does not emit significant amounts of UV radiation, so you generally do not need to worry about this type of light affecting your serum's performance or requiring high SPF sunscreen specifically for it.

It is always recommended to use sunscreen when you are exposed to actual sunlight to protect your skin and maintain the benefits of your skincare routine.
