- Start with a low-strength, buffered retinoid every other night; the AAD advises the least intense formula you can find.
- CeraVe Resurfacing Retinol Serum suits post-acne marks, INKEY Starter Retinol suits sensitive skin, and The Ordinary Granactive Retinoid 2% Emulsion is the cheapest gentle option.
- Olay Retinol24 Night Serum is fragrance-free and hydrating but costs the most; most brands don't disclose retinoid percentages.
- Save The Ordinary Retinol 1% for after a few comfortable months, and skip retinoids during pregnancy.
The best retinol serum for beginners is a low-strength, buffered formula you can use every other night without peeling. Good starter picks are CeraVe Resurfacing Retinol Serum for post-acne marks, The INKEY List Starter Retinol Serum for sensitive skin, The Ordinary Granactive Retinoid 2% Emulsion on a tight budget, and Olay Retinol24 Night Serum for fragrance-free hydration. Save The Ordinary Retinol 1% for later.
Whichever you shortlist, you can check its ingredient list against your own skin type by scanning the barcode or label with the ingredient scanner in Pori.
Below is a side-by-side table, how we chose, a short take on each product, and when to move up. We picked on three things: strength, delivery and buffering. This is an ingredient-and-evidence comparison based on each brand's published formula and dermatology sources; we didn't test the products on skin. For how to actually start a retinoid night by night, see our retinol for beginners guide.

How did we pick these retinol serums?
We looked for gentle strength, a delivery system meant to reduce irritation, and soothing or barrier ingredients alongside the retinoid. The AAD's advice for newcomers is to use the least intense retinoid formula you can find, every other night at first, so we left out high-strength products for now.
- Strength: lower is better at the start. The catch is that the AAD notes there's no standard requirement for over-the-counter products to disclose their retinol percentage. When a brand doesn't say, the ingredient list helps a little: under FDA rules, ingredients at 1% or less may be listed in any order after those above 1%, so a retinoid far down the list is usually present in small amounts.
- Delivery: brands use encapsulated, slow-release or newer retinoid forms to make retinoids easier to tolerate; The INKEY List, for example, says its slow-release complex introduces retinoids while minimizing the risk of irritation. Independent proof of these claims is limited. A lab study of 12 commercial products found most retinoids degraded noticeably over six months, while hydroxypinacolone retinoate (HPR) was the most stable, which is one reason HPR shows up in several picks.
- Buffering: ingredients like niacinamide, ceramides, glycerin and soothing agents don't make a retinoid weaker, but they can make the experience more comfortable. The AAD says starting slowly and using moisturizer helps reduce irritation, which matters more for darker skin, where irritation can trigger dark marks.
What are the best retinol serums for beginners?
1. CeraVe Resurfacing Retinol Serum: best for post-acne marks
CeraVe made this one for post-acne skin. Its product page says it helps reduce the look of post-acne marks, refine pores and smooth texture, with encapsulated retinol, niacinamide, licorice root, three ceramides and hyaluronic acid. It's free of added fragrance and labeled non-comedogenic. CeraVe doesn't give a retinol percentage, but retinol sits 19th of 33 ingredients, after the thickeners, a sign of a small dose. CeraVe's directions say to use it daily at night and to space out applications if your skin feels uncomfortable.
Why pick it: the most barrier support of the group, and a clear focus on flat dark marks. Watch out for: it won't help dented acne scars, and you can't tell how strong it is. Read our full CeraVe Resurfacing Retinol Serum review.
2. The INKEY List Starter Retinol Serum: best for sensitive skin
This is the only pick here that discloses its retinoid strengths. The INKEY List says it uses a slow-release dual-retinoid complex of 1% Granactive Retinoid Pro Plus and 0.01% retinal, plus 0.2% SymRelief 100 to help soothe skin. The brand describes it as designed for first-time retinol users, including those with sensitive skin, and recommends starting two to three nights a week and increasing gradually.
Why pick it: disclosed strengths, a gentle start schedule written into the directions, and a low price at $15. Watch out for: the formula also contains a tiny amount of retinal, a different retinoid from retinol; see retinal vs retinol for how the two compare. The brand also mentions rosacea-prone skin, but if you have rosacea, ask a dermatologist before starting any retinoid.
3. The Ordinary Granactive Retinoid 2% Emulsion: best budget pick
At $12.10, this is the cheapest of the gentle options. The Ordinary describes it as a creamy serum for all skin types built on hydroxypinacolone retinoate, and its own entry-level retinol page suggests people prone to sensitivity may prefer this emulsion. Two caveats: the brand doesn't explain what the "2%" measures, and retinol appears in the ingredient list even though the product is marketed as a retinol alternative. The page claims results comparable to retinol with less irritation but cites no study for it.
Why pick it: low cost, comfortable texture, stable active. Watch out for: thin human evidence for HPR alone, and the brand asks you to refrigerate it after opening and finish it within three months. See our Granactive Retinoid 2% Emulsion review.
4. Olay Retinol24 Night Smoothing Serum: best for dry skin and fine lines
Olay's serum pairs a "Retinoid Complex" of retinol and retinyl propionate with niacinamide and a peptide, according to its product page. Olay says it's fragrance- and dye-free, suits normal, sensitive, dry and oily skin, hydrates for 24 hours, and visibly improves fine lines after 28 days of daily use. It doesn't disclose a retinoid percentage, and retinol and retinyl propionate are listed right after water, dimethicone and glycerin.
Why pick it: a silky, hydrating feel and niacinamide in a fragrance-free formula. Watch out for: it's the priciest pick at $39.99 on olay.com, and an early spot on the ingredient list means you shouldn't assume it's the weakest option. Start every other night like any other retinoid.
5. The Ordinary Retinol 1% in Squalane: for later, not first
This is a straightforward 1% retinol in a water-free squalane base for $9.90. The Ordinary calls the formula "expert-level" and suggests working up from its 0.2% and 0.5% versions first. The brand also warns that irritation, redness and peeling can occur early on, especially around the eyes and mouth.
Why it's here: it's a cheap, disclosed-strength next step once a starter product feels easy. If you want a first step from the same brand, the Retinol 0.2% in Squalane ($8.10) is its entry-level version.
Which one should you choose?
Match the product to your skin and your main goal:
- Flat dark marks after breakouts, oily or combination skin: CeraVe Resurfacing Retinol Serum.
- Sensitive skin, or you want to know exactly what's in it: The INKEY List Starter Retinol Serum.
- Smallest budget, dry or easily irritated skin: The Ordinary Granactive Retinoid 2% Emulsion.
- Dry skin and early fine lines, happy to pay more: Olay Retinol24 Night Smoothing Serum.
- Already comfortable on a starter retinoid for a few months: The Ordinary Retinol 0.5% or 1% in Squalane.
If you have active moderate or cystic acne, a cosmetic retinol is unlikely to be enough on its own. Cleveland Clinic notes that topical retinol doesn't always work on severe acne scars that are sunken or raised, and a dermatologist can offer prescription retinoids or other treatments.
How do you start a new retinol serum safely?
Go slow, use it at night, and protect your skin from the sun. These steps apply to every pick above:
- Patch test first. The AAD suggests applying a product to a small test spot twice daily for seven to 10 days and stopping if you get redness, itching or swelling.
- Use it every other night for the first couple of weeks, as Cleveland Clinic suggests, then build up gradually.
- Apply to dry skin, then moisturizer.
- Wear broad-spectrum sunscreen every morning, because retinol makes skin more sensitive to sunlight.
- Use one retinoid at a time. The Ordinary, for example, says not to combine its retinoids with other retinoids, direct acids or direct vitamin C. Our guide to skincare ingredients not to mix explains the common clashes.
Expect results to take a while. Cleveland Clinic says it takes several weeks before skin looks and feels better, and DermNet notes that for acne it may take 12 weeks or longer to see improvement with topical retinoids.
Who shouldn't use a retinol serum?
Skip retinoids if you're pregnant. The AAD says retinoids should not be used during pregnancy, and The Ordinary advises avoiding its retinoid products while pregnant or breastfeeding. People with eczema should be cautious too: DermNet notes topical retinoids can make eczema worse because of their drying effect. If you have rosacea, perioral dermatitis or very reactive skin, talk to a dermatologist before starting, and see one for any reaction that doesn't settle once you stop the product.
