Compare Products: Vitamin Illuminating Serum vs Super C Serum
Ingredient Analysis
EQQUALBERRY Vitamin Illuminating Serum is a hydration-focused formula with five hyaluronic acid forms, ceramide, and barrier actives. Vibriance Super C Serum targets brightening with vitamin C and hexylresorcinol in a silicone base. The better pick depends on your primary skin concern.
EQQUALBERRY Vitamin Illuminating Serum contains ceramide, five hyaluronic acid forms, squalane, and shea butter. Vibriance Super C Serum offers only one hyaluronic acid form.

User Feedback Patterns
Users consistently praise the serum for being lightweight and non-sticky. Several reviewers specifically note it absorbs quickly, unlike typical vitamin C serums.
Many users report improved skin tone and reduced dark spots within 2 to 4 weeks of consistent use. The brand cites an Intertek study showing 57.49% melanin area reduction in one week, though the full study methodology is not publicly available.
At 30ml, several users note the bottle runs out quickly, especially with daily use on face, neck, and body as suggested by the brand.
Some users report minimal visible change after several weeks. Most negative reviews cite underwhelming brightening results rather than irritation or breakouts.
Users consistently highlight the lightweight, non-sticky feel. The silicone base absorbs quickly and works well under makeup. This is the most consistently positive aspect across reviews.
Some users report fading of dark spots after 4-8 weeks of use. Others report no visible improvement after months. Expectations set by the brand's marketing may exceed what a 2% vitamin C derivative can deliver.
Multiple long-term users report no wrinkle reduction. The formula does not contain retinoids, peptides, or other ingredients with strong evidence for wrinkle improvement. Hydration from hyaluronic acid may temporarily plump fine lines.
The brand specifically targets women over 50 and this demographic represents the core user base. Reviews from this group are generally more positive, noting the serum as gentle and pleasant to use daily.
Which Should You Buy?
EQQUALBERRY Vitamin Illuminating Serum offers great value at a lower price point. Vibriance Super C Serum may be worth the premium if you want 3-O-Ethyl Ascorbic Acid (2%).
