I want to start with something that nobody in this space says directly: most people buying face serums in India right now do not actually need half of what they are using. They buy niacinamide because they saw it on Instagram, layer it with vitamin C because someone on YouTube said glowing skin, add a hyaluronic acid serum because it was Rs 400 on Nykaa and sounded like a good idea, and then wonder why their skin looks the same three months later.
The serum category has exploded in the last four years. Every brand from Minimalist to Mamaearth to imported Korean brands is fighting for shelf space. And the problem is not that the ingredients are bad. Most of them are genuinely effective. The problem is that people are buying without knowing what they actually need, and the brands are not going out of their way to educate customers because educated customers buy less product. So let me break this down properly.
What Each Ingredient Actually Does
Niacinamide
This is Vitamin B3, and it is probably the most forgiving active ingredient available right now. It helps control oil production, reduces the appearance of large pores, evens skin tone, and strengthens the skin barrier. It also has anti-inflammatory properties that calm redness and irritation, and it gradually fades dark spots caused by post-acne marks and sun exposure.
Who actually needs it: anyone with oily skin, large pores, post-acne marks, or uneven tone from the Indian sun. Which is most of us.
The thing about niacinamide that nobody stresses enough is that it is safe for daily use, morning and night, across almost all skin types. It does not cause purging, it does not make you photosensitive, and it stacks well with almost everything else. If you are a total beginner to serums and want one place to start, start here.
Vitamin C
Vitamin C is a potent antioxidant that fights free radical damage caused by sun exposure and pollution, while also brightening the skin and supporting collagen synthesis. For people living in Indian cities with high UV exposure and pollution, this is genuinely useful, not just marketing. The thing that trips people up is that Vitamin C comes in multiple forms. Pure ascorbic acid (L-Ascorbic Acid) is the most studied and most effective, but it is also the least stable. It oxidizes quickly when exposed to light and air, which is why properly formulated Vitamin C serums come in dark glass or opaque packaging. If you buy a Vitamin C serum in a clear bottle and leave it near a window, it will oxidize and turn orange, and an oxidized Vitamin C serum is not just useless, it can cause irritation.
Derivatives like Ethyl Ascorbic Acid and Ascorbyl Glucoside are gentler and more stable, which makes them better for beginners or sensitive skin, but slightly less potent. Use Vitamin C in the morning, not at night. It works best as a protective layer before sunscreen, not as a repair ingredient.
Hyaluronic Acid
This one has been oversold more than any other ingredient. Hyaluronic acid is a humectant. It draws moisture from the environment into your skin. It does not add moisture from within, it pulls it from outside. It attracts moisture to the skin, and consistent use reduces the appearance of fine lines and makes skin feel plump. The problem is that in dry or low-humidity environments, hyaluronic acid can actually pull moisture from the deeper layers of your skin if there is no moisture in the air to pull from. This is why you apply it on damp skin and always seal it with a moisturizer immediately after. Most people skip the moisturizer and then wonder why their skin feels drier after using an HA serum.
For genuinely dry skin, HA is useful. For oily or combination skin in humid Indian summers, you probably do not need a separate HA serum. Your moisturizer likely already contains it.
Retinol
This is the one ingredient that actually has decades of clinical research behind it. Retinol is a derivative of Vitamin A and remains the most scientifically proven ingredient for anti-aging. It increases cell turnover, stimulates collagen production, and helps fade pigmentation and fine lines. It also has the most potential for going wrong in the hands of a beginner.
Starting with high concentrations or using it daily can overwhelm the skin. Combining retinol with exfoliating acids or benzoyl peroxide increases irritation significantly. And because retinoids increase photosensitivity, your skin becomes more vulnerable to UV damage when using them. Start with a low concentration, 0.25% or 0.5%, and use it only 2 to 3 nights per week initially. Increase frequency only after 4 to 6 weeks as your skin adjusts. Results appear in 6 to 12 weeks with consistent use.
One thing that throws people off is purging. Retinol does not create acne. It simply brings what was already under the skin to the surface faster. Purging is more common if you already had clogged pores and is temporary, typically resolving in 2 to 6 weeks. But if you start getting breakouts in areas where you never normally break out, that is not purging, that is irritation, and you need to stop or reduce frequency. Retinol is exclusively a night-time ingredient. No exceptions.
The Brands
Minimalist
Minimalist was founded in 2020 in Jaipur and focused on active-led formulations specifically for Indian skin.
My honest take: Minimalist built genuine credibility by being transparent about concentrations, keeping packaging simple, and pricing fairly. Their niacinamide 10% + zinc serum at around ₹599 for 30ml is probably the best-value niacinamide product available in India right now. Their retinol range is beginner-friendly because they offer 0.3% as an entry point, which is sensible. The concern going forward is the HUL acquisition. HUL is a massive FMCG company, and FMCG companies optimize for margin and scale. The formulations may not change immediately, but it is worth watching whether the price-to-ingredient-quality ratio shifts in the next couple of years. For now, Minimalist is still a reliable, no-nonsense buy.
The Ordinary
The Ordinary was founded in 2016 in Canada, disrupted global skincare with transparent labeling and low prices, and is now part of Estée Lauder Companies.
The Ordinary is the brand that started the clinical skincare movement that Minimalist essentially adapted for India. Their prices look very low in USD or GBP, but in India, after import duties and shipping, the price-to-value comparison narrows compared to Minimalist. Their Vitamin C products use multiple forms including pure L-Ascorbic Acid at high percentages like 23%, which can be irritating for beginners. For normal or oily skin with tolerance, The Ordinary offers strong potency at reasonable price. For sensitive skin, Minimalist’s more gentle derivatives are the better choice.
One real advantage The Ordinary has is the range. They have products for almost every specific concern, and if you know what you need at a specific concentration, you can find it. The disadvantage is that the range can overwhelm people into buying more than they need.
Deconstruct
A relatively newer Indian brand that has positioned itself on the same transparency-first platform as Minimalist, but with more mid-tier pricing and somewhat more approachable marketing. Their products are decent. The niacinamide serum is well-formulated. However, they are not doing anything that Minimalist is not already doing, at a higher price point. I have not seen a compelling reason to choose Deconstruct over Minimalist for most people, unless a specific product on their range addresses something Minimalist does not cover.
Plum
Plum is better positioned for gentle daily use and reactive skin types, and wins on sustainability and ethical beauty commitments. Their Vitamin C serums are genuinely good for first-time users because they use stable Vitamin C derivatives rather than pure ascorbic acid, which means less irritation risk. Where Plum falls short is on heavy-duty actives. If you want aggressive treatment for pigmentation or texture, Plum is not where I would look. If you want something your girlfriend or mother who has never used actives can start with safely, Plum works well.
Dot and Key
This is a brand I have complicated feelings about. The products are not bad. The niacinamide and alpha arbutin serum in their range does what it claims. But Dot and Key has leaned heavily into packaging and marketing aesthetics in a way that inflates the price beyond what the formulations justify. Dot and Key leads with more dermatology-grade actives compared to Plum and positions itself as the more treatment-focused option. That claim is somewhat true on paper. But you pay a premium for the aesthetic, the packaging, and the brand positioning, more than you pay for ingredient quality that is meaningfully better than Minimalist at half the price. For the same niacinamide concentration, Minimalist costs less and is just as effective.
Dr. Sheth’s
This is one of the more credible Indian brands in the serious skincare space. The founders have a dermatology background and the formulations show it. Their Cica and Ceramide range is genuinely good for people with a compromised skin barrier, which is a real concern for anyone who has been overusing actives. If you have been using retinol or acids too aggressively and your skin is sensitive, irritated, and reacting to everything, Dr. Sheth’s is the brand I would go to for barrier repair products before going back to any active ingredient. That is a specific use case, but a real one.
Mamaearth: Just Say No
I am going to be direct here. Mamaearth sells products with plant-based and toxin-free claims that function as marketing language rather than meaningful standards. Both Dot and Key and Plum are more ingredient-honest than Mamaearth, which is itself a low bar in some product categories. Their vitamin C serum is one of the most purchased face serums on Flipkart, primarily because of price and marketing spend, not because of formulation quality. The concentration of active ingredients is often not disclosed clearly, the packaging for their Vitamin C serum is not UV-protective, and the fragrance in some products can irritate sensitive skin. If you are already a Mamaearth user and happy, that is your call. But I would not recommend starting here when Minimalist exists at similar prices.
The serum market in India will keep growing, more brands will launch, and more ingredients will trend. The way to cut through all of it is simple. Pick one concern, one ingredient that addresses it, use it consistently for 8 weeks, and assess the result before adding anything else. Every brand listed above will try to sell you a 3-step routine of their own products. You almost certainly do not need three serums from the same brand.
