Plum Mandarin & 15% Vitamin C Serum 20ml – Glow Boost | Fragrance-Free | Brightening & Antioxidant Serum for Radiant Skin
Plum has consistently occupied a unique space in the skincare market: high-efficacy, ingredient-led formulas that are also 100% vegan, fragrance-free, and cruelty-free. For consumers who want both performance and ethical clean-beauty credentials — without choosing between them — Plum delivers.
The Mandarin & 15% Vitamin C Serum is a perfect expression of that philosophy. At 15%, this serum sits firmly in the high-strength bracket of cosmetic Vitamin C serums — effective enough to deliver meaningful brightening and antioxidant results, while the addition of Mandarin extract adds a natural botanical dimension that complements the synthetic active beautifully.
🍊 15% Vitamin C — High-Strength, Clean-Beauty Brightening
At 15%, this serum’s Vitamin C concentration is meaningfully potent — above the 10% threshold where clinical efficacy becomes significant, and at a level that delivers real brightening, antioxidant, and collagen-support benefits with daily use.
Brightening: Vitamin C inhibits tyrosinase to progressively reduce the appearance of dark spots, hyperpigmentation, and the general uneven dullness that makes skin look tired and flat.
Antioxidant defense: at 15%, the antioxidant protection against UV-generated free radicals and pollution-related oxidative stress is substantial — contributing to both daily skin defence and long-term complexion quality.
Collagen support: Vitamin C is an essential co-factor in collagen synthesis — daily topical application provides local support for the skin’s own structural protein production, contributing to a firmer, more resilient complexion over time.
🍊 Mandarin Extract — Botanical Brightness
Mandarin (Citrus reticulata) extract brings a natural source of Vitamin C, bioflavonoids, and antioxidant polyphenols that complement the formula’s synthetic Vitamin C in a synergistic way. Bioflavonoids are known to enhance the stability and efficacy of Vitamin C — a pairing that makes the formula’s brightening action more durable and effective than either ingredient could achieve alone.
The Mandarin extract also contributes naturally occurring AHAs at trace levels — gently supporting surface cell turnover without the need for additional chemical exfoliants.
🌿 Fragrance-Free — Plum’s Non-Negotiable
Every Plum formula is fragrance-free — a principled decision that the brand has maintained consistently. In a Vitamin C serum at 15%, this matters particularly: fragrance in a high-concentration active serum significantly increases the risk of sensitization, irritation, and barrier disruption. By removing it entirely, Plum ensures that this serum is safe and comfortable for daily use across all skin types — including sensitive.

🧴 How to Use Plum Mandarin & 15% Vitamin C Serum
Apply in the morning after cleansing and toning. Dispense 3–4 drops onto fingertips and gently press into the face. Allow to absorb before applying moisturizer. Always follow with broad-spectrum SPF — Vitamin C increases UV sensitivity. Can also be used in the evening. Patch test before first use. Build up frequency gradually if new to high-concentration Vitamin C.
