20% Vitamin C Face Serum - 20ml

What you need to know

This is a serum from Derma Co priced at ₹899.

Key ingredients

This serum prominently features 20% Vitamin C, which is a potent antioxidant known for brightening skin, reducing hyperpigmentation, and boosting collagen production. However, vitamin C, especially L-ascorbic acid at high concentrations, can be unstable and easily oxidize, losing its efficacy and potentially causing irritation. Without a full INCI list, it's impossible to tell if stabilizing ingredients like ferulic acid or vitamin E are included, which are crucial for maintaining its potency and extending shelf life. High concentrations of vitamin C can also go wrong by causing redness, stinging, and dryness, particularly for those new to the ingredient or with sensitive skin.

Who should use this

Individuals with established vitamin C tolerance and persistent pigmentation concerns might consider this, provided their skin is not sensitive. It could be suitable for normal to oily skin types looking for a strong brightening agent. Those specifically targeting stubborn dark spots or an overall dull complexion could find it appealing.

Who should skip this

Anyone with sensitive skin, rosacea, or a compromised skin barrier should absolutely skip this high concentration. Pregnant women should consult their doctor before using any active, and if approved, should opt for a 100% mineral sunscreen when using any vitamin C product. New users to vitamin C should start with much lower concentrations, typically 5-10%, to avoid irritation. Individuals with acne prone skin, as described in the Reddit snippet, might find this exacerbates breakouts or causes purging due to its potency.

How to use

Apply 2-3 drops to clean, dry skin in the morning after cleansing and before moisturizing. Follow immediately with a broad-spectrum sunscreen. Do not layer with other active ingredients like AHAs, BHAs, or retinoids in the same routine, as this can lead to over-exfoliation and irritation. Use once daily, preferably in the morning.

What users say

With 34,619 reviews on Nykaa, the general sentiment points towards users seeking a 'glow that makes heads turn.' However, the average score is not available. A Reddit user with normal, dehydrated, and acne-prone skin reported developing pimples and blackheads after use, indicating potential irritation or an unsuitable formulation for their skin type.

Price context

At Rs899, this serum is positioned as an affordable option for a 20% vitamin C product. However, the lack of a full INCI makes it difficult to compare its true value against other brands. Alternatives in this price range often have lower concentrations or use more stable vitamin C derivatives. While the price is attractive, the potential for instability and irritation at this concentration means users might not get the full benefit or could experience adverse reactions, making it less of a value proposition if it doesn't work out.

Final take

This 20% Vitamin C serum from Derma Co is a potent, budget-friendly option, but its high concentration and opaque ingredient list are significant drawbacks. We would only recommend this for those with resilient skin already accustomed to high strength actives. For most, starting with a lower concentration and a fully disclosed INCI list would be a much safer and more effective approach.
