What do the experts say about C E Ferulic?
SkinCeuticals C E Ferulic carries a Guru Score of 79% from 28 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.
What do the experts say about Niacinamide 10% + Zinc 1%?
The Ordinary Niacinamide 10% + Zinc 1% carries a Guru Score of 66% from 21 independent experts. The gurus split sharply on this one. Those who favor it praise how it calms inflammation, regulates oil, and helps with acne and discoloration at an affordable price, though they note the 10% strength may irritate sensitive skin. However, several experts worry the 10% concentration is unnecessarily high and have seen it trigger irritation and contact dermatitis in practice, especially in younger or sensitive skin. The consensus among those cautious: niacinamide works best at 2-5%, and the ingredient is now common enough in other products that a dedicated serum may not be needed.
