Obagi ELASTIderm Advanced Filler Concentrate Review

Obagi ELASTIderm Advanced Filler Concentrate is a 20ml targeted treatment built around the peptide Acetyl Hexapeptide-1, delivered via a precision-tip applicator for spot-treating specific lines rather than covering the whole face. It's positioned as a topical, non-injectable option for focusing product on particular areas — forehead lines, brow furrows, crow's feet, laugh lines and fine lines around the lips.

What is Obagi ELASTIderm Advanced Filler Concentrate?

This is a lightweight, silky-textured concentrate packaged with a precision-tip applicator, which is the main thing that sets it apart from Obagi's other ELASTIderm serums — it's built for dabbing onto individual lines and creases rather than smoothing over the whole face. The formula is fragrance-free and described by Obagi as suitable for all skin types, including sensitive skin. Data gap: Obagi's own product copy quotes specific percentage improvements from in-house clinical and usage testing (described as "data on file at Obagi Cosmeceuticals LLC"), but with no independently published study or methodology attached. Per our house policy on unsourced clinical statistics, those figures aren't repeated here — see the ingredients section below for what we can confirm from the published formula.

Key ingredients

The headline active is Acetyl Hexapeptide-1, a synthetic peptide included for its role in supporting the skin's own elasticity-related processes and helping improve the appearance of fine lines where they're applied. Alongside it, Glycerin acts as a humectant to draw and hold moisture in the skin, while Shea Butter (Butyrospermum Parkii) contributes emollient, nourishing properties to help soften the treated area.

The rest of the formula is built for texture and glide rather than active benefit: Dimethicone gives the concentrate its lightweight, non-greasy finish and helps it sit comfortably under makeup, Diglycerin and Pentylene Glycol support hydration and absorption, and Beta-Glucan is included for its skin-soothing and barrier-supporting properties. Full published INCI: Aqua/Water/Eau, Dimethicone, Glycerin, Coco-Caprylate/Caprate, Pentylene Glycol, Diglycerin, Glyceryl Stearate SE, Microcrystalline Cellulose, Dimethicone/Vinyl Dimethicone Crosspolymer, Butyrospermum Parkii (Shea) Butter, C10-18 Triglycerides, Hydrogenated Olive Oil Stearyl Esters, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Cetearyl Alcohol, Chlorphenesin, Carbomer, Trisodium Ethylenediamine Disuccinate, Beta-Glucan, Caprylyl Glycol, Sodium Hydroxide, Polysorbate 60, Sorbitan Isostearate, Acetyl Hexapeptide-1.

Who it's for

• Anyone wanting to spot-treat specific expression lines — forehead, brow furrows, crow's feet, laugh lines or lip lines — rather than a full-face serum
• People who prefer a topical, non-invasive option to sit alongside (not replace) their regular anti-ageing routine
• Sensitive skin, since the formula is fragrance-free and described as hypoallergenic by Obagi
• Those already using a broader ELASTIderm or retinol product who want a targeted top-up for one or two stubborn areas

It's a less obvious fit for anyone looking for a single all-over anti-ageing serum — the precision applicator is built for small areas, not full-face coverage. For that job, the wider-coverage ELASTIderm Facial Serum is the better starting point.

How to use it

Apply a small amount directly to the targeted line or area using the precision-tip applicator, gently patting it in with an upward motion, twice daily after cleansing and toning. Obagi recommends allowing it to dry for around a minute before applying makeup. For fuller-face coverage, Obagi suggests pairing it with the ELASTIderm Lift Up & Sculpt Facial Moisturiser as part of a wider routine. As with any new active-containing product, a 48-hour patch test on the inner arm before first use is worth doing.

Frequently asked questions

What does Acetyl Hexapeptide-1 do?

It's a synthetic peptide included in this formula to help improve the appearance of fine lines and support the skin's elasticity-related processes where it's applied — it isn't a resurfacing or exfoliating ingredient like a retinoid or acid.

Can I use it under makeup?

Yes. The lightweight, silicone-based texture is designed to absorb without residue; Obagi recommends letting it dry for around a minute before applying foundation or other cosmetics.

How is this different from the ELASTIderm Facial Serum?

This concentrate is built for spot-treating individual lines via a precision-tip applicator, while the ELASTIderm Facial Serum is a pump-dispensed serum designed for broader face, neck and décolletage coverage using Obagi's Bi-Mineral Contour Complex. They use different technologies and are better thought of as complementary than interchangeable.

Safety, sensitivity and pregnancy

The formula is fragrance-free and formulated to be hypoallergenic, but it does contain Cetearyl Alcohol (a fatty alcohol, generally well tolerated) — a patch test before full use is still recommended, particularly for reactive skin. Keep away from the eyes and discontinue use if irritation develops. If you're pregnant or breastfeeding, please contact our team for advice before use.
