DMAE is the ingredient this cream is built around, and it is also the weak link. The evidence that it firms skin is thin and largely tied to the brand that promotes it, without strong independent support.
The "firming" people feel is a temporary tightening of the skin, not a lasting structural change. It is a real sensation, and it wears off. Nothing in the jar is rebuilding the skin's structure.
The rest of the formula is reasonable. Tetrahexyldecyl ascorbate is a stable, oil-soluble vitamin C derivative, and vitamin E and kukui nut oil are sensible emollients. The main questions are the price and the headline ingredient.

It is a perfectly pleasant moisturizer and people do report their skin looking tighter and smoother after using it. That effect is real, in the sense that they are not imagining it.
Tetrahexyldecyl ascorbate is a legitimate vitamin C derivative — oil-soluble, stable, and one of the better-evidenced of the derivatives.
Vitamin E and kukui nut oil are reasonable emollients and antioxidants.
The formula is not junk. The question is the price and the headline ingredient.
DMAE is the weak link, and it is the whole brand. The evidence that DMAE firms skin is thin, largely brand-associated, and lacks robust independent double-blind support. Dr. Perricone both promotes DMAE and sells it — that is not disqualifying, but it means the main voice vouching for the ingredient has a direct financial interest in it.
The "firming" people feel is a temporary tightening, not a structural change. It is a real sensation and it wears off. Nothing in this jar is rebuilding anything.
The $75 list price is undercut constantly. Ulta discounts it, Walmart sells it cheaper, and Costco has sold two for around $53. A price that the manufacturer's own retail partners routinely halve is not a real price.
It contains fragrance, in a product aimed at mature skin — which tends to be drier and more reactive.
There are three near-identical versions — the plain one, an SPF 30 version, and a tinted SPF 30. Check the box.
