C-Glow

Clinically optimized Vitamin C formula with excellent stabilization strategy, but severely compromised by aggressive pH and short shelf-life instability. The 15% L-Ascorbic Acid at pH 3-3.4 with synergistic Ferulic Acid + Vitamin E represents textbook antioxidant formulation chemistry. However, the efficacy score is capped at 4.0 because: (1) Pure Ascorbic Acid at this pH is inherently unstable—the brand admits an 8-month shelf-life from production, with degradation beginning immediately; (2) By the time users receive it (2-4 weeks old), potency is already compromised; (3) The low pH makes this unsuitable for sensitive skin despite marketing claims of "all skin types"; (4) Dimethyl Isosorbide is an excellent solvent choice, but cannot fully overcome Vitamin C's notorious instability in aqueous solutions. This is a well-formulated product undermined by the fundamental chemistry of its active ingredient. If you're looking for vegan skincare, this is worth evaluating.

This is a fragrance free skincare formula, making it suitable as fragrance free skincare for sensitive skin. The Gold Standard active ingredients in Unknown C-Glow are L-Ascorbic Acid. Potential irritants detected: Phenoxyethanol.

Unknown C-Glow has a safety score of 4.1/5. It contains potential irritants including Phenoxyethanol. Patch testing is recommended. As a fragrance free moisturiser suitable for sensitive skin care, it avoids common triggers for reactivity.

Based on its formulation, Unknown C-Glow is best suited as a moisturizer for sensitive skin.
