When to Use Vitamin C: Morning or Night?
Last updated 28 June 2026 · 8 min read
Wondering when to use vitamin C, in the morning or at night? It is one of the most common skincare questions, and the short answer is that morning is ideal for most people, with night a perfectly good option too. This guide explains why, how to layer vitamin C with your other products, the different forms to look for, and a few clean Australian-made picks. For the benefits themselves, see what vitamin C does for your skin.
KEY TAKEAWAYS
- Morning is ideal for most people: vitamin C is an antioxidant that helps defend skin against daytime stressors, and it sits beautifully under SPF.
- Night works too, especially for sensitive skin, or if you alternate evenings with a retinol.
- Layer it early: after cleansing, before heavier creams and oils. Always finish the morning with sunscreen.
- Gentler, stable forms (like THD ascorbate and Kakadu Plum) suit daily use and sensitive skin.

QUICK ANSWER
For most people, morning is the best time to use vitamin C: as an antioxidant it helps defend skin against daytime stressors like pollution and UV-induced free radicals, and it layers well under sunscreen. Night is also fine, and can suit sensitive skin or routines that alternate with retinol. Apply it early in your routine, after cleansing, and always finish the morning with SPF.
Vitamin C: AM or PM?
Both work, so the right choice comes down to your skin and your routine.
Why morning works best
During the day your skin meets UV and pollution, two of the biggest sources of oxidative stress. As an antioxidant, vitamin C helps defend against those free radicals, so a morning application gives you that support through the day, and it works nicely alongside (never instead of) your sunscreen.
When night makes sense
Night-time vitamin C is a great option if morning use feels like too much for sensitive skin, or if you would rather keep your mornings simple. Some people alternate evenings, vitamin C one night, a retinol or retinol alternative the next, so each active has room to work. A vitamin C facial oil is a lovely way to use it at night.
How to Layer Vitamin C
Vitamin C goes on early, after cleansing and any toner or mist, so it sits close to the skin. A simple order:
Morning
- Cleanse (or refresh with a mist)
- Vitamin C serum
- Hydrating serum or moisturiser
- SPF, always, as your final step
Night
- Cleanse
- Vitamin C serum or oil
- A richer moisturiser or night cream to seal
A few pairing notes: vitamin C and hyaluronic acid are a lovely match, apply vitamin C first, then hyaluronic acid on slightly damp skin. Vitamin C and niacinamide work fine together for most people. And if you use a retinol, many prefer vitamin C in the morning and retinol at night, or alternating evenings. For the full order of everything, see how to layer skincare products.
If you would rather keep things to one step, a vitamin C day cream is the easiest way in.
The Different Forms of Vitamin C
"Vitamin C" covers several forms, which behave differently:
- L-ascorbic acid: the purest, most potent form, but less stable and best suited to skin that tolerates actives well.
- THD ascorbate (tetrahexyldecyl ascorbate): an oil-soluble, stable, gentle form that suits daily use and sensitive skin.
- Sodium and magnesium ascorbyl phosphate: gentle, stable forms, good for reactive skin.
- Kakadu Plum: a native Australian fruit and one of the richest natural sources of vitamin C, used across much of the LAMAV range.
If your skin is sensitive, start with a gentler form and build up.
Tips for Using Vitamin C
- Start slow: every other day to begin with, then build to daily.
- Store it well: keep vitamin C in a cool, dark spot, as light and air can degrade it over time.
- Be consistent: vitamin C rewards regular use more than occasional use.
- Patch test anything new, especially if your skin is reactive.
Always Wear SPF With Vitamin C
This is the golden rule. Vitamin C helps defend against daytime stressors, but it does not replace sunscreen, the two work together. Finish every morning with a broad-spectrum SPF, and reapply every two hours when you are outdoors. Browse the mineral sunscreen collection, or see our guide to mineral sunblock for sensitive skin.

Frequently Asked Questions
Should you use vitamin C in the morning or at night?
Morning is ideal for most people, as vitamin C's antioxidant support is most useful through the day and it layers well under SPF. Night is also fine, and can be gentler for sensitive skin or easier if you keep mornings simple.
Can you use vitamin C twice a day?
Many people can, once skin is used to it. If you are new to vitamin C or have sensitive skin, start once a day (or every other day) and build up.
Can you use vitamin C and retinol together?
It is usually easier to separate them: vitamin C in the morning and retinol at night, or on alternating evenings. That gives each active room to work and is gentler on the skin.
Can you use vitamin C and niacinamide together?
Yes, for most people the two layer happily in the same routine. If your skin is reactive, you can also use one in the morning and the other at night.
Do you need sunscreen with vitamin C?
Always. Vitamin C supports your skin against daytime stressors but does not replace sunscreen. Finish every morning with a broad-spectrum SPF.
