Clean allergen profile with a fragrance free formula.

No synthetic fragrance, no parabens, no EU Annex II banned substances. Diethylene Glycol Monoethyl Ether (Ethoxydiglycol) is a confirmed penetration enhancer used at a concentration suggesting meaningful presence in this formula. It increases how deeply all co-formulated actives absorb through the skin barrier. This is not a prohibited ingredient, but its use at this level in a daily leave-on facial serum represents a material safety consideration that is not communicated to consumers. Additionally, one ingredient is listed as 'Vegetable Oil', which is not a valid INCI name. Without knowing what oil it is, no safety, allergen, or comedogenicity assessment is possible for that ingredient.

The antioxidant combination is well-designed: the stable 3-O-Ethyl Ascorbic Acid derivative, Ferulic Acid, and Vitamin E work synergistically, with Ferulic Acid roughly doubling the photoprotective efficacy of the vitamin combination. Ascorbyl Tetraisopalmitate is an oil-compatible vitamin C form that can reach areas water-based actives miss. CoQ10 regenerates oxidised Vitamin E for sustained antioxidant cycling. Sodium Phytate protects the vitamin C from premature oxidation in the bottle. The Ethoxydiglycol penetration enhancement may increase vitamin C efficacy but also increases absorption of all co-formulated ingredients. 'Vegetable Oil' cannot be evaluated for formulation logic without knowing its identity.

The 10% vitamin C concentration is clearly stated on the label, which is a genuine transparency positive. The 'clinically tested' claim appears on the product but no study is linked or accessible. Ferulic Acid concentration is not disclosed. 'Vegetable Oil' cannot be assessed for claims purposes. No published clinical studies for this formula are accessible.

No clinical study, test report, or safety assessment is publicly accessible for this product despite the 'clinically tested' label claim. The brand states 10% Vitamin C concentration, which is a positive disclosure, but no supporting data is accessible.

The 10% vitamin C concentration is clearly communicated. Ethoxydiglycol's penetration-enhancing mechanism is not disclosed. 'Vegetable Oil' as an unlabelled ingredient fails basic consumer clarity standards, as its identity, comedogenicity, and allergen status cannot be determined.
