La Mer The NEW Rejuvenating Night Cream ingredients: is it worth it?
This is an ultra-luxurious but fundamentally conservative night cream: great barrier support and pleasant texture, but only moderate true anti-aging firepower despite the marketing hype.

The efficacy score sits around the mid–high range because the formula is built on a strong emollient/humectant base (shea butter, multiple oils and butters, glycerin, hyaluronate) plus a cluster of well-studied peptides and antioxidants, yet it lacks any gold-standard retinoid and relies on a mild vitamin C derivative and trace-positioned peptides and botanicals, which likely caps the real-world rejuvenation impact.

EXTERNAL CITATIONS
Palmitoyl Tripeptide-1: Topical application of palmitoyl tripeptide-1 has been shown to stimulate extracellular matrix components (collagen, fibronectin), improving signs of photoaging in clinical and ex vivo models.
Palmitoyl Tetrapeptide-7: Palmitoyl tetrapeptide-7 can reduce the production of pro-inflammatory cytokines such as interleukin-6, contributing to improved skin firmness and reduced wrinkle depth in peptide complexes.
Sodium Hyaluronate: Sodium hyaluronate is a well-established humectant that increases stratum corneum hydration and improves skin elasticity in multiple controlled clinical studies.
Magnesium Ascorbyl Phosphate: Magnesium ascorbyl phosphate is a stable vitamin C derivative that can provide antioxidant protection and modest brightening, though it is generally less potent than L-ascorbic acid at equivalent concentrations.
