The 100 points
We split ELASTIderm Neck and Décolleté Lifting Concentrate into 5 standout parts. Each bar shows what the build earns.
The signature: copper and zinc salts with malonic acid, shown in biopsies to boost new elastin in photoaged skin.
No close retail equivalent: we credit at most 50% of these points.
A gentle vitamin A ester for lines and smoother texture.
Fades the look of sun spots on the chest.
Evens tone and supports the barrier.
Glycerin is the first ingredient and keeps thin neck skin comfortable.
Optional
73 / 100. We have not found a shelf product that closes more of the gap yet.
83 is our ceiling. Bi-Mineral Contour Complex (copper, zinc, malonate) has no close retail equivalent, so we cap it at 50% credit.

One bottle instead of a build. Sorted by match score; scores use the same standouts as above.
CeraVe
No close match yet — we show the nearest formulas.
Why it is close. Covers the retinoid and niacinamide parts. Retinol is stronger than Obagi's retinyl palmitate, so start slowly on the thin neck skin. It has no mineral complex or arbutin.
Naturium
Why it is close. Shares niacinamide and the exact same retinoid ester, plus vitamin C. It also has salicylic acid, so test it on the neck before daily use.
Not an affiliate link.
The Ordinary
Why it is close. Covers the spot-fading part with a stated 2% alpha-arbutin for about $12. It does nothing for firmness or lines on its own.
The Ordinary
Why it is close. The nearest retail copper source for the firming part. It is a different copper form, so it earns partial credit, and it has none of the brightening or retinoid actives.
