User Feedback Patterns

EQQUALBERRY
Lightweight, non-sticky texture

Users consistently praise the serum for being lightweight and non-sticky. Several reviewers specifically note it absorbs quickly, unlike typical vitamin C serums.

Visible brightening within weeks

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.

Small bottle size

At 30ml, several users note the bottle runs out quickly, especially with daily use on face, neck, and body as suggested by the brand.

Results vary by skin type

Some users report minimal visible change after several weeks. Most negative reviews cite underwhelming brightening results rather than irritation or breakouts.

Sunday Riley
Texture and absorption

Users frequently praise the lightweight, watery texture that absorbs quickly without stickiness. Layers well under other products and makeup.

Brightening over time

Consistent reports of improved radiance and brighter complexion with regular use, though dark spot fading varies by individual.

Oil control

Oily skin users report reduced shine and less sebum production throughout the day.

Packaging concerns

Some users note the dropper packaging can cause product to dry and crust around the lid. Others have reported the product arriving discolored.

Price sensitivity

Mixed opinions on value. Some feel the botanical complex justifies the premium; others find it overpriced compared to budget niacinamide options.

Which Should You Buy?

EQQUALBERRY Vitamin Illuminating Serum offers great value at a lower price point. Sunday Riley B3 Nice 10% Niacinamide Serum may be worth the premium if you want Niacinamide (10%).
