Head to Head
Allies of Skin Multi Peptides & GF Serum vs Peter Thomas Roth Peptide Skinjection Serum
A 9 percent lifting complex plus growth factor against a fully itemised 19 percent expression complex: the step-up comparison, adjusted to the verified set.


Allies of Skin Multi Peptides & GF Advanced Lifting Serum
The step-up serum: a 9 percent lifting peptide complex plus a 3 percent growth factor complex, with every level printed on the bottle itself.

Peter Thomas Roth Peptide Skinjection Amplified Wrinkle-Fix Serum
The expression line specialist: a 19 percent peptide complex of amplified Matrixyl and Argireline solutions, in a refillable bottle.
Where They Differ
Lifting system against expression system
Allies pairs its lifting peptide complex with a growth factor complex, sh-Oligopeptide-1 at a printed 3 percent, plus MSM and Copper Lysinate, a system designed for skin that looks less firm overall. The Skinjection serum concentrates on movement lines: Matrixyl Morphomics at 2 percent, Argireline Amplified at 5 percent, Matrixyl Synthe'6 at 2 percent and Argirelox at 10 percent. Same category, different maps of the face. Read your own mirror and the choice usually makes itself.
How each brand documents its formula
Both print percentages, which is why they pair well here, but they document differently. Allies prints two system totals, 9 percent and 3 percent, on the bottle and box. Peter Thomas Roth itemises four components that sum to its 19 percent on the listing and the bottle front. Readers who want to know exactly how much of a named peptide they are buying get the fullest answer from Roth; readers who want the most concentrated overall system get it from Allies.
Tier, format and provenance
Allies sits at prestige tier and is sold on Amazon by Allies of Skin itself, ships from Amazon, the strongest provenance signal in this topic. The Roth serum sits a tier below, in a refillable bottle whose pods reduce repeat cost and waste. Both are unscented pumps at 30 ml, so the practical difference is commitment level and refill economics, not daily handling.

Questions, Answered
Why is the Drunk Elephant Protini serum not in this comparison?
Because it could not be verified. Repeated searches surfaced the brand's own site, Sephora and aggregator pages, but no official Amazon listing with a confirmable ASIN and brand channel signal, and this site only compares products it can verify on Amazon. Readers who want that serum should buy it from the brand or an authorised retailer. The Allies of Skin serum takes its place here as the verified step-up alternative.
Which of the two is better under makeup?
Both are unscented pumps that absorb cleanly. Owners of the Roth serum specifically praise its smooth, primer like finish, while Allies owners advise a brief pause before layering to avoid pilling. For a morning under makeup slot, Roth has the slight edge in owner commentary; for a night slot, the distinction disappears.
