Foxtale's 10% Vitamin C + Glutathione serum offers a well-formulated brightening experience with a stable Vitamin C, but its bold, rapid-result claims outrun the publicly visible finished-product evidence, requiring consumers to manage their expectations.
₹449 • Analysed 18 July 2026
Actives like this can raise sun sensitivity, which India's high year-round UV makes significant, so pairing with a daytime SPF is important; the lighter the vehicle, the better it tends to wear in heat and humidity. The product's MRP is consistent across major platforms at Rs.645 for 30ml. However, significant discounts are frequently available, with quick commerce platforms like Zepto and Blinkit offering the lowest prices, making it considerably more affordable than its stated MRP. This suggests a common pricing strategy of high MRPs with frequent, deep discounts. 1 marketing claim could draw ASCI scrutiny under India's advertising code; the ingredient list is the more reliable guide.
Independent and free. The Clean Sheet takes no money from brands to review, rank, or approve a product. This is a web evidence review, not a Clean Sheet certification. We checked the ingredient list, publicly available test reports, marketing claims, and formula logic using only public information available at the time of review.
The brand states 'clinically tested for glowing, radiant skin' and mentions dermatologists reviewing it positively, with some noting 'visible difference in just three days'. However, specific details of the '8 ways' or the clinical study methodology (sample size, duration, endpoints) are not publicly disclosed. The 10% Vitamin C (Ethyl Ascorbic Acid) is a known brightening agent, but Glutathione and Undecylenoyl Phenylalanine are likely at lower concentrations (below 1% line).
Supported by the general 'clinically tested' claim and dermatologist reviews noting 'brighter tone' and 'acne marks looked lighter'. Ingredient-level research supports Ethyl Ascorbic Acid and Undecylenoyl Phenylalanine for brightening and reducing pigmentation.
A strong time-bound claim. While dermatologists noted 'visible difference in just three days', this is anecdotal evidence from reviewers, not a published clinical study with a stated methodology for this specific 5-day claim. The brand also claims 'visibly get a brighter skin in just 3 days' on quick commerce platforms.
Dermatologist reviews mention 'gentleness, a solid 5/5' and 'No irritation, no purging, just calm, clear progress'. The INCI lists 'Allergen-Free Fragrance' at the end, which supports the sensitive skin claim, though fragrance can still be a concern for some.
Ethyl Ascorbic Acid (Vitamin C) is known to boost collagen production. However, this is ingredient-level evidence, not finished product evidence for this specific claim. No clinical study on the finished product for collagen boosting is publicly visible.
The INCI lists multiple humectants (Propanediol, Propylene Glycol, Betaine, Glycerin, Glyceryl Glucoside) and Squalane, which are known for hydration. The gel-cream texture also supports this claim. Dermatologist reviews also noted 'intense hydration'.
Ethyl Ascorbic Acid (Vitamin C) and Tocopherol (Vitamin E) are well-known antioxidants. Glutathione is also a natural antioxidant. This is strong ingredient-level evidence, but no finished product test for 'shielding against oxidative stress' is publicly visible.
Ethyl Ascorbic Acid inhibits tyrosinase and brightens skin. Undecylenoyl Phenylalanine hinders pigmentation and has in-vitro/in-vivo tests showing efficacy against age spots and melasma. Glutathione also slows tyrosinase. This is strong ingredient-level evidence, but specific finished product clinical data for this claim is not publicly visible.

Mentioned only
Glutathione is a known antioxidant and brightening agent. However, it is listed after Phenoxyethanol in the INCI, suggesting a concentration likely below 1%. The efficacy of topical glutathione for significant brightening is still considered to have 'thin' evidence in human trials.
