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.

La Roche-Posay
Smooth, elegant texture

Users praise the lightweight, quick-absorbing texture. The silicone base and alcohol give it a matte, non-sticky finish that layers well under makeup.

Alcohol causes dryness for some

Users with dry or sensitive skin report dryness and irritation, likely from the denatured alcohol. This is the most common negative feedback.

Effective brightening

Users who tolerate the formula report visible brightening and improved skin tone within 3-4 weeks. The 10% concentration works well for most.

Oxidation over time

Like all L-ascorbic acid serums, users report color change within weeks. Some note it darkens faster than competitors.
