Watermelon & 10% Glycolic Serum

What you need to know

This is a serum with Glycolic Acid. The smallest alpha-hydroxy acid (AHA). Exfoliates dead skin cells on the surface, improves texture, and stimulates collagen over time.

Who should use this: If your concern is rough texture, dull skin, fine lines, or mild hyperpigmentation, this ingredient addresses that directly. 5-10% for daily use, 20-30% for peels (use sparingly). In a cleanser, contact time is too short for the percentage to matter.

This is a serum with Tranexamic Acid. Originally a medication to control bleeding. In skincare, it inhibits melanin production through a different pathway than most brightening ingredients. Increasingly used for stubborn pigmentation.

Who should use this: If your concern is melasma, post-inflammatory hyperpigmentation, dark spots that haven't responded to other treatments, this ingredient addresses that directly. 2-5% is the most common topical range. Can be combined with niacinamide and vitamin C.

This is a serum with Hyaluronic Acid. A humectant that holds up to 1000x its weight in water. Draws moisture from the environment into your skin. Found naturally in your skin but declines with age.

Who should use this: If your concern is dehydrated skin, dry skin, fine lines from dehydration, or all skin types, this ingredient addresses that directly. 0.1-2%. Low molecular weight penetrates deeper. High molecular weight sits on top and plumps. Most products use a mix.

Key ingredients

The star active here is 10% Glycolic Acid, an alpha hydroxy acid (AHA) known for its exfoliating properties, helping to improve skin texture, reduce dullness, and manage excess oil. The INCI list also includes Tranexamic Acid and Kojic Acid, both recognized for their ability to address pigmentation concerns. While these are good ingredients on their own, their presence alongside a high concentration of glycolic acid means a higher chance of over-exfoliation or sensitivity, especially for those new to actives. The brand does not specify the concentration of these additional actives, making it difficult to assess their true impact or potential for irritation.

Who should use this

This serum is best suited for individuals with oily or combination skin struggling with dullness, uneven texture, or mild pigmentation. Those with resilient skin who have previously used chemical exfoliants and understand their skin's tolerance for AHAs may also find this beneficial. It can help manage excess oil and improve overall skin clarity.

Who should skip this

Anyone with sensitive skin, dry skin, or compromised skin barriers should avoid this product. Pregnant women should also skip this due to the high concentration of glycolic acid and the presence of multiple actives; mineral sunscreens are the only recommended sun protection for them. Additionally, if you are currently using other strong actives like retinoids or vitamin C, you should not introduce this serum into your routine, as stacking multiple actives can lead to irritation, redness, and a damaged skin barrier.

How to use

Apply a pea-sized amount to clean, dry skin in the evening, after cleansing. Start by using it 2-3 times a week, gradually increasing frequency if your skin tolerates it well. Always follow with a moisturizer. Sunscreen, preferably a broad-spectrum SPF 30 or higher, is non-negotiable every morning after using this product, even on cloudy days. Do not layer this with any other active ingredients.

What users say

With over 54,000 reviews on Nykaa, users generally praise this 10% glycolic acid serum for its strong exfoliation properties. Many report improvements in texture, pigmentation, and oil control. The common advice among users is to start slowly, given the potent 10% glycolic concentration, and to always use SPF the next day.

Price context

At Rs479, especially with the 20% discount from its MRP of Rs599, this serum offers good value for a high-concentration glycolic acid product in the Indian market. While there are other glycolic acid serums available, few offer 10% at this price point. However, the inclusion of multiple actives without clear concentration details makes it a less straightforward choice compared to a simpler, single-active glycolic serum from a brand like Minimalist, which might offer more predictable results for a similar price.

Final take

This Dot & Key serum is a decent option for those looking for a strong glycolic acid exfoliant at a budget-friendly price. However, the formulation with multiple actives makes it less ideal for beginners or those with sensitive skin. If you have resilient, oily skin and are careful with application, it could be a valuable addition to your routine for addressing texture and dullness.

Same ingredient, different brands

Dot & Key is not the only brand selling a serum with glycolic acid. Here is what else exists at what price. Same active, different formulations. The choice comes down to texture, price, and what your skin prefers.
