User Feedback Patterns
Multiple reviewers note the serum feels very thin and watery. Some appreciate the lightness for layering; others feel it lacks substance on its own.
Users who report positive outcomes typically note improvements in skin hydration and firmness after 1 to 4 weeks of consistent use.
Several users complain that the dropper releases very small amounts, making application tedious for face and neck coverage.
Positive reviews praise hydration and glow. Negative reviews report feeling no difference, questioning whether the NAD+ and peptides deliver visible results at the concentrations used.
Users consistently praise the lightweight oily texture that absorbs well and sits beautifully under makeup. The application experience is rated higher than most L-ascorbic acid serums.
The orange scent is frequently mentioned as a positive. Users who enjoy scented skincare rate this highly. However, fragrance-sensitive users avoid it.
Users appreciate that the golden color remains consistent throughout the product's life. No anxiety about darkening or wasting product due to oxidation.
Brightening results are described as gradual but visible over 4-8 weeks. Some users expecting the immediate 'glow' of L-ascorbic acid find the results slower.
Which Should You Buy?
EQQUALBERRY NAD+ Peptide Boosting Serum offers great value at a lower price point. Sunday Riley C.E.O. 15% Vitamin C Brightening Serum may be worth the premium if you want 15% Tetrahexyldecyl Ascorbate (THD Ascorbate).
