The first time I tried retinol, I used it every night from day one. By the end of the week my chin was peeling, my cheeks stung when I applied moisturiser, and I gave up. The second time, I went slowly. It's now the one active I'd never give up.
This is the plan I wish I'd followed the first time. It's not medical advice. If you're pregnant, breastfeeding, or using prescription acne treatment, speak to your doctor or pharmacist before starting.
Start low
Choose a gentle, low-strength retinol rather than the strongest product on the shelf. Strength matters far less than consistency. A low-strength product used for a year will do more for you than a strong one you abandon after a week.
The 12-week schedule
Weeks 1–2: twice a week. Use it on two non-consecutive evenings, such as Monday and Thursday. On the other nights, use only a gentle cleanser and moisturiser.
Weeks 3–4: three times a week. Add a third evening if your skin feels comfortable. If you're seeing redness or flaking, stay at twice a week for another fortnight.
Weeks 5–8: every other night. Most people can get here comfortably by the second month.
Weeks 9–12: decide. Some people move to nightly use. Plenty of people, including me, stay at every other night forever. That's absolutely fine.
"If your skin is stinging, you're not doing it better. You're doing it too fast."
The sandwich method
If your skin is sensitive, apply a thin layer of moisturiser first, wait a minute, apply a pea-sized amount of retinol for your whole face, then another thin layer of moisturiser. This buffers the retinol so it's less likely to irritate. I did this for my first two months.
What to pause while you start
While your skin adjusts, take a break from other strong actives in the evening, especially exfoliating acids and scrubs. Keep things simple: a gentle cleanser, the retinol, and a barrier-supporting moisturiser or serum. The Calm Barrier Serum is what I use on my non-retinol nights.
SPF is not optional
Retinol can make your skin more sensitive to the sun. Wear a broad-spectrum SPF 30 or higher every morning, including cloudy Irish mornings. If you won't wear sunscreen daily, wait to start retinol until you're ready to.
Purging vs. irritation
Some people get a few extra breakouts in the first weeks, often in areas where they usually break out. That's generally expected and settles within a few weeks. Stinging, burning, a rash, or breakouts in brand new places are different, and a sign to stop and seek advice.
What to expect, and when
Don't judge retinol in the first month. I noticed smoother texture at around eight weeks and more even tone by about four months. It's slow, but it's one of the few things in skincare that keeps rewarding patience.
