What do the experts say about Multi-Peptide + Copper Peptides 1% Serum?
The Ordinary Multi-Peptide + Copper Peptides 1% Serum carries a Guru Score of 89% from 22 independent experts. The serum's texture and hydration earn consistent praise, it absorbs smoothly without greasiness and delivers noticeable moisture to dehydrated skin. Most gurus highlight the value of multiple peptide types (copper for repair, Matrixyl for signaling, Argireline for expression lines) at a low price, though a few note that the copper peptide concentration may not deliver the deep tightening effect some expect, and results tend toward hydration and subtle smoothing rather than dramatic firming. A small number found minimal visible change or mild irritation on their skin, so patch-testing makes sense if you have sensitive skin or use other active ingredients alongside it.
What do the experts say about C E Ferulic?
SkinCeuticals C E Ferulic carries a Guru Score of 76% from 34 independent experts. This serum has solid clinical backing and delivers results for those who tolerate L-ascorbic acid well, but experts genuinely split on whether the £165-185 price tag is justified now that the original patent has expired and affordable alternatives with similar formulas exist. Those with sensitive skin or darker skin tones may find the concentration irritating and should patch-test first, as L-ascorbic acid at this strength triggers redness in a significant portion of people. For normal to dry skin types who know they handle the active well, dermatologists note it remains reliable and worth keeping; for everyone else, gurus suggest exploring cheaper dupes with the same active form before committing to the premium price.
