The Foxtale Eternal Light Gluta-Vit C Advanced Brightening Serum is a daily-use gel-cream formulated to address dullness, uneven tone, pigmentation, melasma, and early signs of ageing. On Flash AI, it earns an AI Score of 92 out of 100, supported by 52 verified reviews across 5 platforms. Users report a visible glow and improved skin tone within 2 to 3 days of starting the serum, making it one of the faster-acting brightening options available at this price point.
The formula centres on two key actives: Vitamin C and Glutathione. Vitamin C is a well-established antioxidant recognised for supporting collagen synthesis and helping to reduce melanin production, which directly addresses pigmentation, uneven tone, and early ageing. Glutathione works in tandem as an antioxidant, contributing to skin brightening and offering protection against free radical damage from environmental stressors. The gel-cream texture absorbs quickly and leaves no sticky residue, making it easy to layer under a moisturiser or sunscreen. The formula is cruelty-free and vegan.
This serum suits dry, normal, combination, and all skin types, and is formulated for both men and women. Reviewers with dry or irritated skin specifically note that it moisturises and soothes while delivering brightening results, which makes it useful beyond just pigmentation correction. Those targeting dark spots, acne marks, melasma, or general dullness report the most consistent improvement. That said, not every user experiences dramatic results. One reviewer noted no significant change after continued use, which is a genuine consideration: individual responses to Vitamin C and Glutathione formulations can vary, and those with deeper or persistent pigmentation may need additional targeted treatments alongside this serum.
Priced between ₹437 and ₹615 across 12 sellers, this serum competes strongly in the budget Vitamin C segment. Review sentiment points to repeat purchases driven by visible glow results and a texture that users rate highly for daily comfort. Reviewers consistently describe it as comparable to or better than more expensive brightening serums. Flash AI recommends this for anyone starting with a Vitamin C serum or looking for a lightweight daily option that targets dullness and pigmentation without a heavy finish. Apply morning and night as directed, follow with sunscreen each morning, and give it a consistent four-week run before drawing conclusions on results.

Apply a small amount to clean, dry skin twice daily, in the morning and at night. Use it after cleansing and before your moisturiser. In the morning, always follow with a broad-spectrum sunscreen, as Vitamin C can increase skin sensitivity to UV exposure.
The serum is listed as suitable for dry, normal, combination, and all skin types. It targets dullness, uneven tone, pigmentation, melasma, and ageing. Reviewers with dry and irritated skin also note that it soothes and moisturises the skin while brightening, which extends its usefulness across a range of concerns.
Glutathione is an antioxidant that works to brighten the complexion and help protect skin from free radical damage caused by environmental stressors. Paired with Vitamin C in this formula, it supports a more even skin tone and reinforces the overall brightening effect of the serum.
Reviewers report seeing an initial glow and reduction in dullness within 2 to 3 days of starting use. More visible fading of dark spots and acne marks tends to appear after a few weeks of consistent daily application. Results can vary depending on your skin type and the severity of your concern.
Reviewers note that the serum soothes dry and irritated skin, suggesting it is relatively gentle in application. However, Vitamin C actives can cause sensitivity in some users. If you have reactive skin, patch test on a small area before applying it to your full face, and start with once-daily use to assess your tolerance before moving to twice daily.
A serum delivers a more concentrated dose of active ingredients than a standard moisturiser. The Foxtale Eternal Light Serum uses Vitamin C and Glutathione to specifically target pigmentation, melasma, and dullness, concerns that a basic moisturiser typically does not address at this level of focus.
This serum is available across 12 sellers online, with prices starting from ₹437. The price range goes up to ₹615 depending on the seller. Comparing current listings across major Indian online platforms will help you find the best available price at the time of purchase.
Reviewers consistently describe the texture as lightweight, non-sticky, and quick-absorbing. It leaves the skin feeling fresh and healthy rather than greasy or heavy. This makes it comfortable for daily use both morning and night, and it sits well under sunscreen or moisturiser without pilling.
Vitamin C is a well-tolerated antioxidant active in skincare, and the specs for this product recommend daily morning and night use. If you are new to Vitamin C serums, starting with once-daily application and observing your skin's response before moving to twice daily is a sensible approach to building tolerance.
The serum lists preventing ageing as a key benefit and uses Vitamin C, which supports collagen synthesis to help keep skin firmer and more youthful-looking over time. Glutathione adds antioxidant protection that helps shield skin from the environmental stressors known to contribute to visible ageing.
