Peptides

A broad peptide serum for around fifteen dollars, with hydration built in. The catch is disclosure: none of the peptide levels are stated, so you take the doses on trust. As a low-cost, low-risk entry into peptides, it is still good value.

The value benchmark of the category: multiple studied peptides at a disclosed copper level for roughly the price of a lunch. It is the obvious first serum to compare everything else against, even if you re-cap it fast.

The packaging is excellent and the price matches it. The growth-factor evidence is real but modest and largely brand-led, and on proven actives per dollar it is very hard to justify over options a tenth of the cost. You are paying for the science story and the bottle.

A polished, comfortable peptide serum from a serious brand, but the evidence and the pricing do not line up. The headline peptides carry limited support, the doses are undisclosed, and you pay a lot for the count on the label. Pleasant to use, hard to justify over cheaper multi-peptide options.

An expensive serum that asks you to buy a proprietary complex on faith while its disclosed actives are present at supporting levels. The ingredients that are named are fine and well-tolerated, but nothing here justifies the price on evidence. You are paying for the brand story and the texture.

An elegant hydrator wrapped around a preliminary-evidence growth factor at a prestige price. The HA base delivers the appearance of hydration reliably; the EGF story is early, undosed and hard to protect in a dropper. You are buying the science pitch, not settled results.

A solid mid-tier pick with a broad peptide lineup. You pay a premium over the budget benchmark for formulation polish rather than for more proven actives.

The packaging respects how delicate the active is, and the underlying idea is interesting. The problem is the evidence: exosome skincare is preliminary, there is no studied use level, and the price is firmly prestige. Promising to watch, hard to recommend at this cost today.
