Retinol vs Vitamin C: Which Should You Buy?
Retinol and Vitamin C address different concerns rather than competing head-to-head. Retinol: vitamin a derivative — cell turnover and fine lines. Vitamin C: antioxidant — environmental defence and brightening.

Where Retinol wins
- • Retinol works by encouraging skin cell turnover, which is why it is associated with smoother-looking texture and a reduction in the visible appearance of fine lines with sustained use over weeks and months. It is converted by the skin into its active form in stages, which is part of why it tends to be gentler, if slower-acting, than stronger prescription retinoids. Results build gradually rather than immediately, and consistent use matters more than concentration.
Where Vitamin C wins
- • As an antioxidant, vitamin C helps neutralise free radicals generated by everyday environmental exposure such as UV and pollution, which is why it is commonly paired with — never as a substitute for — daily sunscreen. It is also widely used for its role in supporting a more even, brighter-looking skin tone over time. Because it oxidises readily, a vitamin C serum that has turned yellow, orange or brown has likely lost much of its effectiveness and is past its useful life.
Who should choose which
Retinol
Retinol is generally used by people wanting to address the visible signs of ageing or uneven texture, and is typically introduced slowly — for example, a couple of evenings a week — regardless of skin type. It is usually not recommended during pregnancy or while breastfeeding, and sensitive or very dry skin often needs a lower strength and a slower introduction to avoid excessive dryness or flaking.
Vitamin C
Vitamin C tends to suit people looking to support skin brightness and address environmental dullness, and is often used across normal, oily and combination skin. Sensitive skin can sometimes find L-ascorbic acid, the most common and potent form, irritating, in which case a gentler derivative such as sodium ascorbyl phosphate is often better tolerated.

Frequently asked questions
- Should I use retinol in the morning or evening?
- In the evening. Retinol degrades in sunlight and increases the skin's sensitivity to UV, so it is applied at night and always followed by sunscreen the next morning, without exception.
- Why is my skin flaking after starting retinol?
- Some initial dryness, redness or flaking is common as skin adjusts, particularly in the first few weeks. Using it less frequently, applying a moisturiser afterwards, and building up gradually usually settles this. Persistent or severe irritation is a reason to pause and seek advice.
- Can I use retinol while pregnant?
- It is generally advised against during pregnancy and breastfeeding as a precaution. Anyone who is pregnant, trying to conceive, or breastfeeding should speak to a doctor or midwife about which skincare actives are appropriate rather than relying on product packaging.
- When should I apply vitamin C in my routine?
- Most commonly in the morning, after cleansing and before moisturiser and sunscreen, since its antioxidant role is often framed around supporting the skin through the day's environmental exposure. Some people prefer an evening routine instead — either can work.
