Best Face Serum 2026: 10 Formulas We'd Actually Repurchase

$185 for 30ml in the US; £169 list at LookFantastic in the UK, where it was 20% off on the day we checked. The formula is 15% L-ascorbic acid with 1% alpha tocopherol and 0.5% ferulic acid, the exact combination shown in Duke University research to multiply photoprotection versus vitamin C alone. It is the serum for someone who wants the version of an ingredient that the studies were actually run on: visible improvement in tone and fine lines over 8 to 12 weeks, worn under sunscreen every morning. The drawback is obvious and double: the price works out to about $6.17 per ml, and the smell, which reviewers on Reddit's skincare boards persistently compare to hot dog water, is real and lingers a minute. If $185 is not happening, we compared the credible cheaper formulas in our SkinCeuticals C E Ferulic dupes breakdown.

$27.95 for 1oz direct from Timeless. Same actives trio as C E Ferulic (L-ascorbic acid, vitamin E, ferulic acid) at a higher 20% concentration of C, in an airless pump that slows oxidation. In the Reddit-sourced rankings at NextBest, this is the community's most-liked C E Ferulic alternative. It is the pick for anyone who wants results-per-dollar rather than the reference formula. Two honest caveats: 20% L-ascorbic acid stings more than 15%, especially over freshly exfoliated skin, and once opened the serum still ambers within roughly three months, so buy the 1oz and use it up rather than stockpiling.

$87 for 30ml at Dermstore in the US; £69 direct from Medik8 in the UK. This uses stabilized retinaldehyde at 0.06%, which converts to retinoic acid in one step instead of retinol's two, so results show faster at a similar irritation level. A widely shared six-month comparison at Well Rested Skincare landed where most long-term users do: a retinoid you tolerate nightly beats a stronger one you can only face twice a week. It suits anyone past retinol basics who does not want a tretinoin prescription. The drawback is the ladder pricing: Medik8 wants you to climb from Crystal Retinal 1 through 24, and UK prices climb with you, from £45 at the bottom strength to £114 at the top, each 30ml bottle a separate decision.

$21.99 list for 1oz at Ulta, on sale at $16.49 when we checked; £23.50 at LookFantastic in the UK, where a 20% code was running the same day. Encapsulated retinol buffered with ceramides, niacinamide, and licorice root extract, aimed at post-acne marks and visible pores rather than deep wrinkles. It is the retinol for beginners and for acne-prone skin in its 20s and 30s. The real drawback: CeraVe does not disclose the retinol percentage, so you cannot know how it compares milligram-for-milligram with competitors, and experienced retinoid users will likely find it too gentle to notice.

$65 for 1oz at Dermstore. A disclosed 1% retinol, the top of the over-the-counter range, cushioned with peptides and licorice extract. This is the strongest honest retinol on this list, for skin that has already adapted to lower strengths and wants prescription-adjacent results without the appointment. Do not start here: at 1%, dryness and flaking in the first month are the norm, not a malfunction, and sensitive skin may never fully settle into it. Buffer it with moisturizer and keep it to two or three nights a week at first.

$39.99 for 30ml at Dermstore. Two weights of hyaluronic acid plus vitamin B5 and madecassoside, the centella-derived soother, in a texture that sensitive and retinoid-irritated skin accepts without protest. This is the hydrator for skin that is both dry and reactive, and it layers cleanly under the retinoids above. The drawback is arithmetic: you are paying four times The Ordinary's price largely for the madecassoside and the elegant texture, and if your skin is not sensitive, that premium buys comfort rather than visibly different results.

$9.90 for 30ml in the US; £8.80 at Boots and theordinary.com. The current formula runs five forms of hyaluronic acid plus ceramides and pro-vitamin B5, a genuine upgrade on the original two-ingredient version. Applied to damp skin and sealed with moisturizer, it plumps fine dehydration lines within days. It is the cheapest competent answer to tight, flaky skin. The mechanism is also the drawback: humectants pull water from wherever it is available, so in dry climates or heated winter rooms, skipping the moisturizer on top can leave skin drier than before. This is a two-step product sold as one step.

$6 for 30ml in the US; £5 in the UK. The best budget serum on this page, full stop. Niacinamide at 10% with zinc PCA regulates oil and fades post-blemish marks over four to six weeks, and NextBest's aggregation of 194 Reddit verdicts shows the pattern clearly: users with oily skin report less shine and less obvious pores within about a month, while a solid minority with sensitive skin get stinging, redness, or dry patches from the 10% dose, which is above the 3 to 5% used in most published niacinamide studies. Start three nights a week. If your skin objects, the concentration, not niacinamide itself, is usually the problem.

$17 for 1oz at naturium.com, Target, and Ulta. Higher doses than The Ordinary (12% niacinamide, 2% zinc PCA) in a noticeably more cosmetically pleasant base with hyaluronic acid, so it sits better under makeup and does not pill. Worth the extra $11 if you wear foundation daily over your serum or found The Ordinary's texture gluey. The drawback follows from the numbers: 12% is the highest niacinamide concentration on this list, and if 10% already stung, this will too. Nobody needs both this and The Ordinary; pick by texture preference.

$135 for 1.7oz at Sephora; £89 list for 50ml at Boots, on offer at £62.30 when we checked. The formula leads with bifida ferment lysate and adds a tripeptide and hyaluronic acid; it will not out-resurface a retinoid, but as a barrier-supporting night layer it delivers the smoother, less puffy morning skin its decades of repeat buyers describe. It suits skin over 35 that finds nightly retinoids too much, or anyone alternating it with retinal nights. Two caveats: the headline ingredient's strongest evidence is brand-funded, and the price per ml is steep enough that Lauder's constant gift-set season is the sane time to buy. We also priced the credible imitators in our Advanced Night Repair dupes comparison.
