Most people can't jump straight to nightly retinal — the honest schedule is two to three nights a week to start, building toward more frequent use over several weeks as your skin adjusts. And one thing up front: retinal is not for use during pregnancy or breastfeeding without your GP's advice, full stop.
General information, not medical advice — always check with your GP, midwife or pharmacist about your own skin and any product you're unsure of.
The pregnancy and breastfeeding rule, stated plainly
Retinal is a vitamin A derivative, and vitamin A derivatives (retinal, retinol, tretinoin) are the one category of skincare where the advice is consistently cautious: don't use them while pregnant or breastfeeding unless your GP or midwife has specifically told you it's fine for your situation. This isn't K-beauty-specific — it applies to any brand, anywhere. If you're pregnant or breastfeeding and want a similar "skin looks firmer" effect, the honest swap is PDRN, which we cover in our piece on what actually rebuilds elasticity.
Why "every night" isn't the starting point
Retinal works by speeding up cell turnover, which is exactly why it can also cause redness, flaking and sensitivity if you go in too hard too fast. Going nightly from day one is the most common reason people quit retinal altogether — not because it doesn't work, but because their skin revolted in week one. A slower build gets you to the same place with a lot less drama.
A realistic build-up schedule
Weeks one and two: two nights a week, always followed by moisturiser to buffer it. Weeks three and four: three nights a week if skin is coping well. From week five, most people can move to every second night, and nightly is genuinely only necessary for some skin types — plenty of people get excellent results staying at three or four nights a week indefinitely. A product like the CELIMAX Vita-A Retinal Shot ($27) is a reasonable place to start this build-up.
What to pair it with (and what to skip)
On retinal nights, keep the rest of the routine simple — cleanser, retinal, moisturiser. Skip other strong actives like high-strength exfoliants on the same night. On off-nights, this is where an overnight recovery step earns its keep; we go through the full logic in Retinal vs Retinol: Which One, and When to Start After Breastfeeding. Sunscreen the next morning isn't optional — retinal use makes skin more sun-sensitive.
Questions mums ask
Can I use retinal while breastfeeding once my baby is on solids?
Vitamin A derivatives are still generally advised against during breastfeeding regardless of your baby's age or feeding pattern — check with your GP before starting, rather than assuming it becomes fine at a certain stage.
Is retinal the same as retinol?
No — retinal converts to the active form of vitamin A in fewer steps than retinol, so it tends to work faster but can also be more noticeable on sensitive skin. We break this down fully in the article linked above.
Do I need to stop niacinamide on retinal nights?
No, niacinamide and retinal generally get along fine and niacinamide can actually help buffer some of the sensitivity — no need to separate them.
Where to start
Once you're cleared to use retinal (i.e. not pregnant or breastfeeding), The Bounce-Back Ritual ($168) is built for exactly this slow-build approach. If you're after the recovery side without retinal, The Overnight Recovery Kit ($144) is the gentler alternative. Have a look through the full range at alinabeauty.com.au.
