What is Retinol?
Retinol is one of the most studied ingredients in skincare for smoothing fine lines, refining texture and helping skin look firmer. It is also the ingredient people are most nervous about, because using too much, too soon can leave skin dry and irritated.
The good news: with the right product and a slow start, almost anyone can enjoy retinol. This guide explains how it works, how to build it into your routine and which of our formulas to start with.

What is retinol?
Retinol belongs to a family of vitamin A ingredients called retinoids. When you apply it, your skin converts it into retinoic acid, the form that communicates with skin cells. In simple terms, it encourages skin to renew itself more quickly, so fresher, smoother-looking skin comes to the surface sooner.
Prescription retinoids are much stronger. Over-the-counter retinol is gentler and works more gradually, which makes it a better fit for most people's routines.
Retinol at a glance
| Format | Best for | Notes |
|---|---|---|
| Serum | Targeted treatment | Apply to clean, dry skin, then moisturize |
| Night cream | Beginners and dry skin | Retinol and moisturizer in one step, usually gentler |
| Encapsulated or "complex" retinol | Sensitive skin | Released more slowly for less irritation |
| Retinol alternatives (bakuchiol) | Very sensitive skin, pregnancy | See our bakuchiol guide |
Benefits of retinol for skin
Smoother-looking lines
By speeding up renewal and supporting collagen, retinol gradually softens the look of fine lines and wrinkles.
Refined texture
Rough, uneven skin starts to feel smoother as older surface cells are replaced more regularly.
Clearer-looking pores
Faster turnover helps keep pores from becoming congested, so they look smaller and breakouts become less frequent.
More even tone
Retinol helps fade the look of uneven pigmentation over time.
How to start retinol
The slow-start plan
- Weeks 1–2: twice a week, at night
- Weeks 3–4: every other night
- Week 5 onward: every night, if your skin is comfortable
Evening routine order
- Cleanser
- Retinol serum, on dry skin
- Hyaluronic acid serum (optional)
- Moisturizer, or use a retinol night cream as your moisturizer
Tip: Use a pea-sized amount for the whole face. More is not better with retinol. Keep it away from the corners of the nose, the eyelids and the lips.
What to pair with retinol (and what to avoid)
| Pairing | OK together? | Notes |
|---|---|---|
| + Hyaluronic acid | Yes, ideal | Offsets dryness. |
| + Peptides | Yes | Firming support with no added irritation. |
| + Niacinamide | Yes | Calms and supports the barrier. |
| + Vitamin C | Split AM/PM | Vitamin C in the morning, retinol at night. |
| + AHAs, BHAs, PHAs | Alternate nights | Using both on the same night can over-exfoliate. |
| + SPF | Essential | Retinol can make skin more sensitive to the sun. Wear SPF 30+ daily. |
Side effects and precautions
Mild dryness, flaking or redness is common in the first few weeks while skin adjusts. If it happens, cut back to every third night and use more moisturizer. Avoid retinol if you are pregnant, trying to conceive or breastfeeding, and stop using it a few days before waxing or other treatments. If you use prescription skincare, check with your dermatologist first.
How long until you see results?
| Timeline | What to expect |
|---|---|
| Week 1–4 | Skin adjusts; some may notice mild dryness |
| Week 4–8 | Smoother texture and a brighter look |
| Week 12+ | Visibly softer fine lines and firmer-looking skin with consistent use |
Frequently asked questions
At what age should I start retinol?
Many people start in their mid-20s to 30s for prevention, but it is never too late to begin.
Can I use retinol in the morning?
We recommend evening only, because retinol can break down in sunlight and make skin more sun-sensitive.
Is retinol safe during pregnancy?
No. Avoid retinol and other retinoids while pregnant or breastfeeding. Bakuchiol is a popular alternative; check with your doctor.
What is "retinol purging"?
Some people see a few extra breakouts in the first weeks as skin renewal speeds up. It usually settles within four to six weeks.
Can I use retinol around my eyes?
Use a formula designed for the eye area, and apply only on the orbital bone, never on the eyelids.
