20% Vitamin C + E Ferulic Acid Serum
The best high-potency alternative to luxury brands, utilizing an airless pump to solve the primary issue with Vitamin C: oxidation. It uses the same synergistic ingredients as the gold standard but at a significantly higher concentration and lower price.
Quality & Materials
Contains 20% L-Ascorbic Acid. Includes Panthenol (B5) for soothing, which helps mitigate the irritation often caused by high-concentration Vitamin C.
Evidence & Testing
Formulated based on the established research of the CE Ferulic ratio, though this specific 20% concentration product has fewer independent RCTs than SkinCeuticals.
Brand Transparency
Guaranteed fresh manufacturing; Timeless prints manufacture dates on boxes and uses opaque yellow packaging to block UV light.
Value Assessment
Exceptional value at under $30 for a 1oz bottle that matches the ingredient profile of $180+ serums.
Why Not Alternatives?
Unlike SkinCeuticals, it uses an airless pump which keeps the product clear and effective for much longer than dropper bottles. It outperforms budget competitors like The Ordinary by including Vitamin E and Ferulic acid for stability, which are often missing in cheaper formulations.
