Retinol Serum

Retinol Serum is a fast-absorbing retinol for deep lines, rough texture, visible pores and age spots. It supports the skin’s natural renewal for a smoother, more refined and even-looking complexion.

Applied at night only, starting two to three nights a week and built up gradually — always with SPF the next day.

Key benefits
Renews and refines

Fades age spots

Helps even the look of age spots and uneven tone over time.

Comfortable, gradual formula

Designed to be introduced slowly so skin can build tolerance.

What to expect

With consistent evening use, introduced gradually, most people notice:

  • A smoother, more refined surface
  • Softened deep lines over time
  • A more even-looking tone
  • Skin that looks fresher and renewed

Descriptive of the typical experience with consistent use. Individual results vary.

Loved & recommended

Retinol is the most-studied anti-ageing active there is; the mistake people make is going too hard, too fast. This is formulated to be introduced gradually, which is exactly the right advice. Slow and consistent, with SPF the next day, and it delivers on texture and tone over time.

The science behind the formula

Retinol is one of the most-studied anti-ageing actives, working by supporting the skin's natural renewal. The key is introducing it gradually — start two to three nights a week, always follow with SPF the next day, and build up as your skin adjusts.

FAQs
How do I start with retinol?

Two to three nights a week to begin, on clean dry skin, then build up as your skin adjusts. Always wear SPF the next day.

Morning or night?

Night only. Retinol makes skin more sun-sensitive, so daytime SPF is essential.

Can I use it with vitamin C?

Yes — many people use vitamin C in the morning and retinol at night.

My skin feels dry at first — is that normal?

Some dryness or flaking is common as skin adjusts. Reduce frequency if needed and always moisturise.

Can I use it with exfoliating acids?

Introduce one at a time and avoid using strong acids on the same night as retinol until your skin is well adjusted.

How much should I use?

A pea-sized amount for the whole face, on dry skin, followed by moisturiser.

Is it safe during pregnancy or breastfeeding?

No — avoid retinol during pregnancy and breastfeeding, and speak to your doctor about a pregnancy-safe alternative.

Is it suitable for sensitive skin?

Start slowly — once or twice a week — and buffer it with moisturiser. Stop if irritation persists.

How should I store it?

Keep it somewhere cool and out of direct sunlight with the cap closed, so the actives stay stable.

How is it shipped, and can I return it?

Shipping is free on every order with no minimum, and there is a 30-day, no-questions-asked return guarantee if it is not right for you.

Still getting use to using the serum. I used the R and R lotion before. This has made my skin smoother but I have sometimes spilt it on myself. I find lotion easier to apply.

Retinol Serum

Wow! I added this to my daily facial care along with the anti-aging serum and I can’t believe how quickly it has improved my skin even more. I didn’t think my skin could get any better than it has with the ant-aging serum because it already looked great, but it has improved the texture and blurred my fine lines even more. Highly recommend this product.
