Vitamin C and Retinol: Your Skincare Day and Night

Vitamin C and Retinol: Your Skincare Day and Night

What’s the “Morning C, Nighttime A” skincare routine?
As the name suggests, using a vitamin C product in the morning and a product containing retinol – or other vitamin A derivatives – at night is a great anti-aging skincare method.

With the purpose of daytime protection plus nighttime repair, using these two active ingredients in tandem can stimulate collagen production and achieve the multiple benefits of brightening, pore care, and anti-aging care in just one routine.


Morning C: Vitamin C Serums
A powerful antioxidant, vitamin C offers terrific defense for your skin against free radicals, external stimulants and sun damage (photodamage) during the day.

Not only do high-quality vitamin C serums help to encourage the product of collagen for smoother skin, but they can also repair skin damage, soothe inflammation, and prevent hyperpigmentation.

The experts agree. “Vitamin C is perhaps the most potent topical antioxidant we have,” says dermatologist Joshua Zeichner, M.D. “It neutralizes free radical damage and protects the skin against UV light and other environmental aggressors, as well as blocking abnormal production of pigmentation to even skin tone and fade dark spots.”

Nighttime A: Vitamin A Serums
Once they enter the skin, Vitamin A derivatives (retinol, retinal, retinyl palmitate) transform into retinoic acid and deliver pore-tightening and anti-aging effects.

Nighttime is also the prime time for your skin’s repair and recovery from sun damage during the day, which is why it’s important to double down on potent skincare ingredients like vitamin A.
