The Plum Calendula & 10% Vitamin C Barrier Boosting + Glow Serum is a dual-action face serum that works to brighten the complexion and strengthen the skin barrier simultaneously. It addresses multiple concerns including dullness, pigmentation, dark spots, uneven skin tone, dry skin, and enlarged pores in a single product. It earned an AI Score of 87/100 based on 139 verified reviews across 5 platforms, with standout scores in Glow & Brightness (90) and Texture & Absorption (88), reflecting strong reviewer consensus on its core promises.
The active ingredient list includes 3-O-Ethyl Ascorbic Acid, a stable Vitamin C derivative that targets brightening and pigmentation, alongside Calendula Officinalis Flower Extract for its calming and skin-soothing properties. Niacinamide targets uneven skin tone and pore appearance. The Ceramide Complex and Ceramide AS work together to repair and reinforce the skin barrier. The formula is alcohol-free, which lowers the risk of irritation and dryness. It comes in a dropper bottle that supports precise application and limits air exposure to the Vitamin C actives. The serum is dermatologist-tested and carries a shelf life of 19 months.
This serum suits most skin types and works best for those dealing with dullness, pigmentation, or a weakened skin barrier. Reviewers with combination and oily skin appreciate the lightweight, non-greasy texture that absorbs quickly and layers well under moisturiser. That said, not all users see dramatic results, and a portion of community feedback flags potential for breakouts. The dropper has drawn criticism for being difficult to operate consistently. If you have acne-prone skin, introduce the serum gradually and track your skin's response over the first few weeks. Some users have raised concerns about batch consistency, so buy from a verified seller.
At ₹198 to ₹550 across 14 sellers, this serum offers a strong ingredient stack for its price. The combination of a stable Vitamin C form, barrier-repairing ceramides, Niacinamide, and calming Calendula in a dermatologist-tested, alcohol-free formula is competitive at the lower end of that range. Review sentiment skews positive, with brightening as the most consistently reported outcome. Source it at or near ₹198 from a verified seller and it delivers clear value for a multi-concern brightening and barrier serum.

Apply 3 to 4 drops to clean, dry skin before your moisturiser. Since the formula contains Vitamin C, morning application paired with sunscreen helps protect against UV-triggered pigmentation. You can use it once or twice daily, adjusting based on how your skin responds in the first week.
Yes. The specs list all skin types as suitable, and reviewers with combination and oily skin specifically note the serum absorbs quickly without leaving a greasy finish. It layers well under sunscreen and moisturiser and does not cause heaviness or congestion for most users.
3-O-Ethyl Ascorbic Acid is a stable derivative of Vitamin C and a key listed ingredient in this serum. Regular ascorbic acid is highly prone to oxidation when it contacts air and light, which reduces its efficacy quickly. The derivative form resists degradation more effectively, helping maintain brightening and pigmentation-targeting activity over the serum's 19-month shelf life.
Some users report noticing a brighter complexion after as few as three uses. For concerns like dark spots and pigmentation, consistent daily use over several weeks delivers more meaningful results. Reviews from users who tracked their skin over four or more weeks carry the most reliable signal on long-term outcomes.
The serum is dermatologist-tested, alcohol-free, and listed as suitable for all skin types in the specs. Reviewers note the formula leaves out parabens and sulphates, which reduces irritation risk. A small number of users did report breakouts, so if your skin reacts easily, patch test on the inner arm for a few days before full-face use.
This formula adds a Ceramide Complex, Ceramide AS, and Calendula Officinalis Flower Extract alongside the Vitamin C and Niacinamide. The ceramides repair and reinforce the skin barrier, which most standalone Vitamin C serums do not address. This makes it a better fit for skin dealing with both brightening needs and a compromised or dehydrated barrier at the same time.
The serum is available from ₹198 to ₹550 across 14 sellers. To find the ₹198 price point, check major Indian retail platforms where multiple sellers list the product and compare. Always buy from a verified seller to reduce the risk of receiving a counterfeit or inconsistent batch, a concern some community members have flagged.
The serum has a lightweight, liquid texture that absorbs quickly without leaving a greasy or sticky residue, making it comfortable for daily use. Its listed scent is green tea, which reviewers describe as pleasant and refreshing. The non-heavy finish means it layers cleanly under moisturiser or sunscreen without pilling.
The serum uses 3-O-Ethyl Ascorbic Acid, a stable Vitamin C derivative, in an alcohol-free formula, which lowers the risk of stinging or dryness compared to more aggressive Vitamin C formats. The serum carries a dermatologist-tested certification. Pair it with a broad-spectrum sunscreen during morning use to protect skin and support the brightening action of the Vitamin C.
The dropper bottle format limits the amount of air that enters the container with each use compared to pump-top or wide-mouth bottles, which slows oxidation of the Vitamin C actives. Oxidation is the main reason Vitamin C serums lose potency over time. For best results, store the serum in a cool, dry spot away from direct sunlight and close the cap firmly after each use.
