Can You Use Retinol and Vitamin C Together? A Dermatology-Informed Guide

June 11, 2026

Vitamin C and retinol are two of the most evidence-backed ingredients in skincare. You can use both. The main question is not whether, but when and how.

What vitamin C is good at

Vitamin C is a daytime favourite for good reason. A review in Nutrients highlights its antioxidant role in defending skin against UV-induced free radical damage, alongside its support for collagen synthesis (Pullar et al., 2017, PMID 28805671). Pairing an antioxidant with sunscreen in the morning is a sensible daytime strategy.

What retinol is good at

Retinol belongs to the retinoid family, the most studied group of ingredients for visible skin ageing. A review in Clinical Interventions in Aging notes that while prescription tretinoin is the most investigated, gentler retinoids such as retinaldehyde and retinol are considerably less irritating, which makes them more practical for everyday use (Mukherjee et al., 2006, PMID 18046911). Retinoids are typically used at night.

Why many people split them by time of day

Using vitamin C in the morning and retinol at night is a common, low-fuss approach. It puts antioxidant support where it is most useful during daylight, keeps your retinoid in its preferred evening slot, and reduces the chance of irritation from layering two strong actives at once. This is a matter of comfort and routine rather than a hard rule.

If you want to use both in one routine

Introduce one active first and let your skin adjust before adding the second.
Start retinol two or three nights a week and build up slowly.
Buffer with moisturiser if you notice dryness, and never skip daytime SPF, since retinoids can make skin more sensitive to sun.

At Verdo we stock Medik8 C-Tetra vitamin C for mornings and the Medik8 Crystal Retinal range for evenings, which lets you start gentle and step up over time. Our Parnell team can help you choose a strength to begin with.

Frequently asked questions

Can you use retinol and vitamin C together?

Yes. Many people simply use vitamin C in the morning and retinol at night, which suits each ingredient's strengths and lowers the chance of irritation. They can also be layered in one routine if your skin tolerates it.

Why is vitamin C used in the morning and retinol at night?

Vitamin C offers antioxidant support that is most useful during daylight alongside sunscreen (Pullar et al., 2017), while retinoids are traditionally applied in the evening. The split is about comfort and routine, not a strict rule.

Will using both irritate my skin?

It can if you start too fast. Introduce one active at a time, begin retinol a few nights a week, buffer with moisturiser if needed, and always use SPF during the day.

Which is better for fine lines, retinol or vitamin C?

Retinoids are the most studied ingredients for visible ageing, with gentler forms like retinaldehyde and retinol being less irritating than prescription options (Mukherjee et al., 2006). Vitamin C complements this with antioxidant and collagen support. Many routines use both.
