The Plum 15% Vitamin C Face Serum with Mandarin is a brightening treatment built to target dark spots, hyperpigmentation, and dull skin tone through consistent daily use. It holds a Flash AI Score of 82/100, drawn from 5881 reviews across 5 platforms, with brightness and gentleness each scoring 85. These scores reflect consistent satisfaction across a large and diverse buyer base. The serum suits all skin types, including sensitive and acne-prone, and carries dermatologist-tested and cruelty-free certifications.
Plum builds this serum around Vitamin C as its primary active, with the brand's own product description specifying the form as 15% Ethyl Ascorbic Acid, a stable derivative the brand describes as clinically proven. Japanese Mandarin and Kakadu Plum also feature as active ingredients, reinforcing the brightening focus of the formula. Collagen appears in the active ingredient list as well. The formulation is fragrance-free, paraben-free, and vegan, and the dropper bottle format enables controlled, precise application. Reviewers with sensitive skin consistently note no irritation or breakouts, pointing to the gentleness of the Vitamin C form used here.
Reviewers praise the lightweight, quick-absorbing texture that leaves no oily residue. The serum layers well under moisturiser and sunscreen and does not pill under makeup, making it a strong choice for both morning and evening routines. Consistent buyers report noticeable improvement in skin brightness and a more even complexion over time. That said, some buyers question whether the full 15% concentration delivers its stated potency in practice. A subset found limited impact on acne scars or deep blemishes, and a small number reported mild stickiness or allergic reactions. A patch test before full application is advisable, especially for oily or reactive skin types. Some users also noted a difference in performance between trial packs and larger bottles.
At ₹140 at its lowest price point across 11 sellers, this serum delivers strong value for a stable, dermatologist-tested Vitamin C formula. The 5881-review base across 5 platforms reflects sustained real-world use over time, lending weight to the reported brightening and tone-evening benefits. Flash AI recommends this serum if your primary goal is reducing dark spots from sun exposure, improving overall radiance, or building a consistent Vitamin C step into your skincare routine on a measured budget. If acne scarring or deep pigmentation is your core concern, this serum may not serve as a standalone treatment. At its upper price of ₹672, it remains competitively placed in the Vitamin C serum segment. Buy from a verified seller to reduce the quality inconsistency some reviewers noted between pack formats.

Plum recommends using this serum both in the morning and at night. Apply it after cleansing and toning, before your moisturiser. If you use it in the morning, follow with a broad-spectrum sunscreen to protect the results and prevent further pigmentation from forming.
The product specs list compatibility with all skin types, including oily, dry, combination, sensitive, and acne-prone. Reviewers with sensitive skin report no irritation or breakouts with regular use. The lightweight, non-greasy texture makes it practical for oily skin too. A patch test is advisable if you have a history of allergic reactions to skincare actives.
Ethyl Ascorbic Acid is the specific form of Vitamin C used in this serum, as stated in the brand's own product description. Plum positions this as a super stable formulation, which addresses the common problem of Vitamin C becoming unstable or losing potency over time. Reviewers confirm the serum causes no irritation, which aligns with the gentle profile this form is known for.
Reviewer feedback points to noticeable improvement in skin brightness and radiance with consistent daily use, though exact timelines vary by skin type and concern. Users report receiving compliments on their skin's appearance after incorporating this serum into a regular routine, suggesting meaningful results emerge over several weeks rather than after a few applications.
A small number of reviewers have reported mild stickiness or allergic reactions after use. The formula carries a dermatologist-tested certification and scores 85 for gentleness on the Flash AI scale, but individual skin responses vary. A patch test on a small area before full-face application is advisable, particularly for reactive or oily skin types.
This serum uses Vitamin C at 15%, placing it in the mid-to-high range for over-the-counter brightening serums.

Plum formulates it with Ethyl Ascorbic Acid, a stable and gentle form, and the product carries a dermatologist-tested certification.

This serum targets dark spots and hyperpigmentation through its 15% Vitamin C formulation, which the brand describes as clinically proven for reducing pigmentation. Consistent use helps fade stubborn dark spots and even out skin tone, both of which are common results of prolonged sun exposure. Pairing it with a broad-spectrum sunscreen in your morning routine supports the results and helps prevent new sun-induced pigmentation from forming.
