SkinMedica vs SkinCeuticals: TNS, HA5, Retinol and Price Compared

SkinMedica vs SkinCeuticals: the short answer

Pick SkinCeuticals if you want stated active percentages, studies with published sample sizes, or a flagship serum that costs $110 less. Pick SkinMedica if you want labels with no fragrance and no denatured alcohol, or a dedicated neck cream.

SkinMedica and SkinCeuticals both sell anti-aging skincare, priced from $80 to $295 across the eight products compared here, four per brand. This is a label-and-data comparison, not a hands-on test. Every price, ingredient list, and result below comes from each brand's US site.

The biggest gap is disclosure. SkinCeuticals prints concentrations such as 15% L-ascorbic acid and 0.5% retinol. SkinMedica publishes none for TNS Advanced+, HA5, or Retinol Complex 0.5, and its clinical statements cite data on file. The labels flip that picture: none of the four SkinMedica products lists fragrance or denatured alcohol, while three of the four SkinCeuticals products list one or the other.

Choose this if

• Choose SkinCeuticals if you want to know how much of each active you are paying for. C E Ferulic lists 15% L-ascorbic acid, 1% vitamin E, and 0.5% ferulic acid, and Retinol 0.5 states 0.5% pure retinol.
• Choose SkinMedica if fragrance or denatured alcohol bothers your skin. None of its four products here lists either one.
• Choose SkinMedica for the neck and chest. Neck Correct Neck and Décolleté Cream is the only neck product among the eight.

TNS Advanced+ vs C E Ferulic: which flagship serum?

SkinMedica TNS Advanced+ and SkinCeuticals C E Ferulic do different jobs, and C E Ferulic costs $110 less for the same 1 fl oz. TNS Advanced+ is a growth factor and peptide serum for the look of wrinkles and sagging, used morning and evening. C E Ferulic is a vitamin C antioxidant serum for the morning, under sunscreen.

TNS Advanced+ pairs two formulas: TNS-MR, a growth factor blend with a peptide complex, and RSC Advanced, a mix of botanicals, marine extracts, and peptides. You take one pump from each chamber and mix them in your hand. The growth factors come from human fibroblast conditioned media. Growth factors have some published research, such as a 2003 pilot study of topical growth factors, but that research cannot tell you what this serum does.

C E Ferulic's current bottle is an enhanced formula: the classic 15% vitamin C, 1% vitamin E, and 0.5% ferulic acid, plus carnosine and dandelion root extract. A 2005 study reported that ferulic acid stabilizes a solution of vitamins C and E and doubles its photoprotection of skin. That supports the base combination for photoprotection. It is not a wrinkle study, and it predates the current formula.

What each brand's own testing reports

Both brands report their own results, and those results mix two kinds of testing. Clinical or instrumental results are measured or graded by researchers. Consumer self-assessments are people rating their own skin, which shows how users felt, not how much their skin changed.

SkinMedica says TNS Advanced+ is clinically proven to address sagging skin at week 4, reports improvements in the appearance of sagging at 8 weeks, and says results keep improving through 24 weeks. On a psychometric scale, patients felt they looked up to 6 years younger after 12 weeks. That one is a self-assessment. Every figure cites data on file, with no sample sizes.

For C E Ferulic, SkinCeuticals lists a 32% reduction in the appearance of wrinkles, 31% more firmness, and 42% more even tone. Those numbers come from a 16-week clinical study of 50 Caucasian men and women ages 40 to 60, run in 2013 on an earlier version of the serum. Neither brand's figures are independent, but SkinCeuticals prints the study size, ages, and length.

HA5 vs H.A. Intensifier: which hyaluronic acid serum?

SkinMedica HA5 is cheaper per ounce and lists no denatured alcohol. SkinCeuticals H.A. Intensifier costs less at checkout, states its hyaluronic acid percentage, and has a clinical study behind it.

Both are current versions. SkinMedica calls HA5 Hydra Collagen Hydrator the modernized HA5 Rejuvenating Hydrator, and SkinCeuticals lists the original H.A. Intensifier as discontinued.

SkinMedica says HA5 holds twice the hyaluronic acid of its previous formula and hydrates for up to 48 hours. Its percentage results are self-assessments from 29 people at 12 weeks: 90% said their skin looked dewy and healthy, and 83% said it looked visibly plumper.

SkinCeuticals ran a 12-week clinical study of 81 women ages 35 to 65, Fitzpatrick skin types I to VI, and reports fine lines visibly filled by 24%. A 3D volume analysis of 74 of those women measured 0.69cc and 0.84cc of volume improvement in the left and right cheeks, which the brand markets as equivalent to 1cc of hyaluronic acid. That is an instrumental measurement. A serum still does not do what an injection does.

Retinol Complex 0.5 vs Retinol 0.5: which retinol?

SkinMedica Retinol Complex 0.5 costs $10 less than SkinCeuticals Retinol 0.5 and lists no denatured alcohol, but only SkinCeuticals states the retinol percentage.

SkinMedica does not list the retinol percentage. "0.5" appears only in the product name, so the matching names do not tell you the two share a strength. Both are step-up products: SkinMedica says Retinol Complex 0.5 is for skin already conditioned with Retinol Complex 0.25 or another retinoid, and SkinCeuticals says Retinol 0.5 suits skin preconditioned with Retinol 0.3.

Both brands tell beginners to start at no more than twice a week, wear sunscreen, and avoid use during pregnancy. SkinMedica says mild redness, peeling, and irritation are expected. SkinCeuticals says visible results typically start after 12 to 24 weeks.

Retinol as an ingredient has independent support, including a 2007 study on improvement of naturally aged skin with vitamin A (retinol). That is ingredient research, not a test of either product. Our retinol guide covers how to start.

Which is better for anti-aging and firming, SkinMedica or SkinCeuticals?

SkinCeuticals has the more detailed wrinkle evidence, and SkinMedica has the only product here made for the neck. TNS Advanced+ makes the sagging claims covered above, without sample sizes.

A.G.E. Interrupter Advanced Cream

A.G.E. Interrupter Advanced Cream is a rich face cream at $185 for 48 ml, with 18% Proxylane, 4.25% wild fruit flavonoids, 3% HEPES, and 1% niacinamide. SkinCeuticals tested it for 12 weeks on 77 women ages 35 to 75, Fitzpatrick types I to VI, who used it twice daily with sunscreen. Reported results:

• 14% reduction in global fine lines
• 11.5% reduction in forehead wrinkles
• 11% reduction in nasolabial folds
• 7% reduction in marionette and glabellar wrinkles, and 7% for crow's feet lines

The figures are modest, but they are measured, and the protocol is on the page. The page also cites results from pairing the cream with in-office procedures, one of them alongside another SkinCeuticals serum, so those figures do not describe the cream alone. The cream contains fragrance, listed 32nd, plus limonene, coumarin, and linalool.

Neck Correct Neck and Décolleté Cream

Neck Correct Neck and Décolleté Cream costs $135 for 50 ml. Dimethicone is its second ingredient. SkinMedica highlights green microalgae, shiitake extract, rice protein, lemon balm, peptides (the label lists acetyl tetrapeptide-2), and paracress extract, which it credits with reducing the appearance of platysma bands. The brand calls the cream clinically proven to visibly lift, firm, and smooth skin, but publishes no sample size or study length. Our guide to neck wrinkles covers the rest of a neck routine.

No cream lifts skin the way a procedure does. Our lifting vs firming cream guide explains what those label words can mean.

Are SkinMedica and SkinCeuticals the same company?

No. SkinMedica, founded in Carlsbad, California, is owned by Allergan Aesthetics, an AbbVie company. SkinCeuticals is owned by L'Oréal, which acquired it in 2005.

Which is cheaper, SkinMedica or SkinCeuticals?

SkinCeuticals is far cheaper for the flagship serum, while SkinMedica is cheaper per ounce for hyaluronic acid and retinol. HA5 costs $72 more than H.A. Intensifier at checkout but holds 20 ml more, so it comes out lower per ounce.

Prices were read from skinmedica.com and skinceuticals.com on September 17, 2026. SkinMedica offered 10% off through Subscribe and Save, and SkinCeuticals offered 5% off with a subscription. Sales and sets change these numbers.

Which is better for sensitive skin, SkinMedica or SkinCeuticals?

SkinMedica, going by the labels: none of its four products lists fragrance or denatured alcohol, while three of the four SkinCeuticals products list one or the other.

On the SkinCeuticals side, C E Ferulic lists no fragrance, no named fragrance allergens, and no denatured alcohol, and the brand includes sensitive skin among its suitable types. Retinol 0.5 lists dry, normal, oily, and combination skin, not sensitive. Patch-test either brand, and start any retinol slowly.
