Retinol is the most researched ingredient for the visible signs of ageing, and also the one most people start too fast. A slow, patient start is the difference between skin that adapts comfortably and skin that peels, stings and gives up in the first month.
What retinol does
Retinol is a form of vitamin A. In the skin it's converted into a more active form that supports cell renewal. Over time and with consistent use, clinical studies have shown improvements in the appearance of fine lines and the overall appearance of naturally aged skin. It can also help refine texture and make tone look more even.
Retinol versus other retinoids
"Retinoids" is the family name. Prescription retinoids are stronger and are prescribed by doctors for specific conditions. Cosmetic retinol is gentler, which makes it suitable for everyday routines, but it still needs a thoughtful introduction.
When to start
Many people introduce retinol in their late twenties or thirties, but there's no strict age. What matters more is that your skin barrier is healthy when you begin. If your skin is currently irritated or sensitised, repair the barrier first.
How to start: the slow method
- Weeks 1–2: two evenings a week, on clean, fully dry skin, followed by moisturiser.
- Weeks 3–4: three evenings a week if your skin feels comfortable.
- After that: build up gradually to every other night, or as your skin tolerates.
Use a small amount for the whole face. Avoid the eye contour and the corners of the nose and mouth, where skin is thinner.
The "sandwich" method for sensitive skin
If your skin is sensitive, apply a thin layer of moisturiser, then retinol, then more moisturiser. It softens the effect while your skin adapts.
What to expect
Some dryness, flaking or mild sensitivity in the first few weeks is common. If it happens, reduce frequency and moisturise more; don't push through burning or significant irritation. Visible changes usually take several weeks to months of consistent use. There is no guaranteed timeline.
Sunscreen is non-negotiable
Retinol is used at night, but daily broad-spectrum sunscreen the next morning is essential. It protects the skin while it renews and prevents undoing your progress.
What not to combine
- Don't use two retinoid products at the same time.
- Keep exfoliating acids on different nights.
- Skip retinol on clay-mask nights and after procedures, unless your dermatologist advises otherwise.

Who should be careful
- If you're pregnant or breastfeeding, retinoids are generally not recommended. Speak to your doctor.
- If you use prescribed skin treatment, including prescription retinoids, don't add retinol without your doctor's advice.
- If your skin is very sensitive or reactive, start with the sandwich method and a lower frequency.
Where SW Vitality fits
SW Vitality is an antioxidant-rich phyto-extract formulation enriched with niacin, retinol, vitamin C and tocopherol. Because it contains retinol, use it in the evening, start slowly, and use it instead of, not as well as, any other retinoid product.
When to see a dermatologist
If you develop persistent burning, swelling, significant peeling or irritation that doesn't settle when you reduce use, stop and seek advice.

Good to know
Can I use retinol every night?
Some people build up to nightly use, but many get good results every other night. Let your skin's comfort guide you.
Do I need sunscreen with retinol?
Yes. Daily broad-spectrum sunscreen is essential when using retinol, and a good habit regardless.
