Pairs a copper peptide with bakuchiol, which is commonly chosen as a gentler stand-in for retinol. Useful if you would rather get a peptide and a resurfacing-style active in one step than layer two products with competing pH requirements.
States a liposomal 2% GHK-Cu on the label, which is the commercially available answer to the permeation problem. Encapsulation is the delivery route with the most published characterisation behind it, though head-to-head human data against a plain serum is still missing.
Names GHK-Cu directly on the label rather than listing only copper tripeptide-1, and ships as a two-pack, so it covers a long enough run to judge tolerance before committing to one expensive bottle.
An oral capsule format. Worth knowing before you buy that the published GHK-Cu research is topical, injected or in animal models, with no human trial supporting swallowing it. Treat this as a category that exists rather than one the evidence backs.
Delivers the peptide in a beef tallow base rather than a water-thin serum, which suits drier skin and occlusive-last routines. The trade-off is that a heavy anhydrous base is harder to layer under other actives.
A liquid oral format. The same caveat applies as with capsules: the human evidence on GHK-Cu is topical, and oral dosing is not supported by published trials.
