The Plum 15% Vitamin C Face Serum is a daily treatment that targets dull skin, dark spots, hyperpigmentation, and uneven skin tone. It uses a stable Vitamin C derivative alongside antioxidant-rich botanicals and suits both morning and evening use. Flash AI scores this serum 78 out of 100, based on 5,876 verified reviews across 5 platforms. It scores 85 for Glow and Radiance and 80 for Hyperpigmentation and Tone, with reviewers frequently noting visible improvement in skin radiance after three weeks of consistent, twice-daily use.
The active core is ethyl ascorbic acid, a stable and gentle Vitamin C derivative that reviewers with sensitive skin find less irritating than conventional forms. Kakadu Plum, one of the richest natural sources of Vitamin C, adds antioxidant support to help fight free radical damage in the skin. Japanese Mandarin supports skin firmness. Collagen also appears in the formulation as an active ingredient. The formula is fragrance-free and paraben-free, with a lightweight texture that absorbs quickly without residue. The serum comes in a dark bottle that protects the photosensitive Vitamin C from light and oxidation, preserving its efficacy over time.
This serum suits all skin types including oily, dry, combination, sensitive, and acne-prone. It carries dermatologist-tested and cruelty-free certifications and is vegan and made in India. Reviewers targeting dark spots and dull skin report consistent improvement with twice-daily use over three weeks or more. That said, some users question whether the stated 15% concentration is accurate, noting the product may lean more toward a mandarin-based formula rather than a potent Vitamin C serum. A few buyers also note texture variation between batches, with a second purchase feeling more oily and less effective compared to an earlier version. If you are new to Vitamin C serums, start with once-daily use before progressing to twice daily.
This serum sells for between ₹354 and ₹660 across 12 sellers, offering solid value at the lower end of the range. For everyday glow maintenance, dark spot fading, and a stable Vitamin C entry point, it earns its Flash AI score. The lightweight, fragrance-free formula and broad skin type compatibility make it easy to integrate into any routine without disruption. Buy from a trusted seller at ₹354 to maximise value, and store the bottle away from direct light to protect the Vitamin C from oxidation.

This serum contains 15% Vitamin C, formulated as ethyl ascorbic acid, a stable and gentle derivative. Reviewers with sensitive skin find it non-irritating and report it effective for daily use. Some users have questioned whether the concentration delivers full potency, noting the formula may lean more toward a mandarin-based serum. Consistent twice-daily use over three weeks or more is the appropriate period to assess results for your skin.
Apply this serum after cleansing and toning, before heavier moisturisers or sunscreen, following the thinnest-to-thickest layering principle. The specs confirm it is suitable for both morning and evening use. Since the formula is lightweight and quick-absorbing, it sits comfortably under creams and SPF. If you use other treatment products, introduce them one at a time and observe your skin's response before layering multiple actives.
Yes. The specs confirm this serum is suitable for AM and PM use, and the brand recommends twice-daily application. In the morning, apply it before sunscreen for daytime antioxidant support. In the evening, use it as part of your nighttime treatment step. Most reviewers who reported visible results applied it twice daily consistently over several weeks.
Yes. The specs list sensitive, acne-prone, dry, oily, and combination skin types as suitable. The serum uses ethyl ascorbic acid, a gentler Vitamin C derivative, and reviewers with sensitive skin report finding it non-irritating. It is also fragrance-free and carries a dermatologist-tested certification. If you have reactive skin, starting with once-daily use for the first week before moving to twice daily is a sensible approach.
Reviewers report noticeable improvement in skin radiance and texture after approximately three weeks of consistent use. Results for dark spots and hyperpigmentation take longer and vary between individuals. Reviewers who used the serum twice daily for four or more weeks reported more consistent outcomes. Short-term impressions from under two weeks of use are not a reliable way to judge a treatment serum like this.
Most reviewers, including those with sensitive skin, report no irritation, which is consistent with the ethyl ascorbic acid formulation and fragrance-free profile. No widespread irritation concerns appear in the review analysis. The dermatologist-tested certification further supports its use on reactive skin. If you are new to Vitamin C actives, starting with once-daily application and monitoring your skin for the first one to two weeks is advisable before increasing frequency.
This serum is available from 12 sellers, with prices ranging from ₹354 to ₹660. To get it at ₹354, compare current listings across major Indian retail platforms at the time of purchase. Prices vary with promotions and seller stock, so checking multiple sources before buying is the most reliable way to secure the lowest price.
The serum has a lightweight, quick-absorbing texture that reviewers describe as comfortable and non-greasy, leaving no oily residue after application. Most users find it easy to layer under a moisturiser or sunscreen. A few reviewers noted that a second purchase felt more oily compared to their first, pointing to some batch-to-batch variation in texture. For most users, the finish is clean and suitable for daily use across all skin types.
Store the serum away from direct light and heat. The dark bottle packaging specifically helps protect the photosensitive Vitamin C from light-induced oxidation, and reviewers note this as a practical design choice. Keep it in a cool, dry place away from direct sunlight to maintain the formula's effectiveness throughout its use. Avoid storing it in warm or brightly lit spots such as bathroom windowsills.
The specs do not state a specific period-after-opening timeline for this serum. With Vitamin C formulations, using the product within a reasonable period after opening is advisable to get the best results from the active ingredient. The dark packaging helps slow oxidation and preserves potency for longer. If you notice a significant change in colour or consistency, that may indicate the formula has started to degrade.
