![The two brands' own sunscreen product photographs side by side - Dot & Key's Watermelon Cooling Sunscreen body spray and Mamaearth's Ultra Light Indian Sunscreen tube - for this per-millilitre price comparison in August 2026]()
We read Dot & Key's and Mamaearth's own product feeds on 18 August 2026 - 206 priced variants and 250 - and found something neither brand advertises: neither publishes a compare-at price on anything. Zero of 206, zero of 250. No struck-through figures, no percentage badges.
Which leaves one honest comparison: what a millilitre costs. Dot & Key is cheaper on face wash and serum; Mamaearth on moisturiser and shampoo; sunscreen is close. And on both stores, buying the multi-pack rather than the single bottle is worth about half the per-unit rate.

Neither Brand Publishes an MRP. That Changes How You Compare Them
We read both catalogues from the brands' own product feeds on 18 August 2026: 150 products and 206 priced variants at Dot & Key, 250 and 250 at Mamaearth. The first thing worth reporting is an absence. Neither brand carries a compare-at price on a single variant - zero of 206 at Dot & Key, zero of 250 at Mamaearth. There is no struck-through number and no percentage badge anywhere on either store's own feed.
That is the reverse of every marketplace shelf, where the badge is the loudest thing on the card and usually the least informative. Here the price is simply the price. So the only comparison available is also the only one worth making: what a millilitre or a gram costs, with multi-packs multiplied out.
| Category | Dot & Key | D&K median | Mamaearth | Mamaearth median | Cheaper per unit |
|---|
| Sunscreen | 19 SKUs, Rs. 5.41–29.75 | Rs. 8.90 | 14 SKUs, Rs. 3.00–10.98 | Rs. 7.98 | Mamaearth, narrowly |
| Face wash | 13 SKUs, Rs. 2.14–3.69 | Rs. 2.49 | 28 SKUs, Rs. 2.33–4.95 | Rs. 2.85 | Dot & Key |
| Serum | 13 SKUs, Rs. 18.33–24.95 | Rs. 19.97 | 6 SKUs, Rs. 16.63–99.80 | see note | Dot & Key, on consistency |
| Moisturiser | 11 SKUs, Rs. 3.42–8.25 | Rs. 8.25 | 16 SKUs, Rs. 2.25–4.99 | Rs. 2.75 | Mamaearth, clearly |
| Shampoo | 1 SKUs, Rs. 1.98 | Rs. 1.98 | 13 SKUs, Rs. 1.25–4.95 | Rs. 1.33 | Mamaearth, by catalogue |
The short version. Dot & Key is cheaper and far more consistent on face wash and serum. Mamaearth is cheaper on moisturiser, shampoo and - narrowly - sunscreen, and it is the only one of the two with a full body-and-hair range. If you buy face actives, Dot & Key. If you buy everything for a household, Mamaearth.
Serum Is Where the Two Brands Diverge Most
Dot & Key's serum shelf is 13 SKUs priced between Rs. 18.33 and Rs. 24.95 a millilitre - a spread of about 36 per cent from cheapest to dearest, which is unusually tight. Its cheapest is a 30 ml Cica and salicylic acid serum at Rs. 550, and its dearest a 20 ml vitamin C serum at Rs. 499. Whatever you pick, you are paying roughly the same rate.
Mamaearth's serum shelf is six SKUs and the rate swings by a factor of six, from Rs. 16.63 a millilitre for a two-pack of the Vitamin C Daily Glow serum at Rs. 998 for 60 ml, to Rs. 99.80 for a 5 ml Glow Serum Blush at Rs. 499 - which is a makeup product wearing the word serum rather than a treatment serum, and we are flagging it as such rather than letting it distort a median. Excluding it, Mamaearth's serums run about Rs. 16.63 to Rs. 43.80 a millilitre.
| The cheapest of each thing we priced | Product | Price | Per ml or g |
|---|
| Cheapest sunscreen per gram | Mamaearth Mineral Based Sunscreen, 50 ml x 3 | Rs. 450 for 150 ml | Rs. 3.00 |
| Cheapest face wash per ml | Dot & Key Watermelon Gel Face Wash, 175 ml | Rs. 375 | Rs. 2.14 |
| Cheapest serum per ml | Mamaearth Vitamin C Daily Glow Serum, 30 ml x 2 | Rs. 998 for 60 ml | Rs. 16.63 |
| Cheapest moisturiser per gram | Mamaearth Cocoa Rich Moisturizer, 200 g | Rs. 449 | Rs. 2.25 |
| Cheapest shampoo per ml | Mamaearth Rosemary / Onion Shampoo, 180 ml | Rs. 225 | Rs. 1.25 |
| Dearest thing we priced | Mamaearth Glow Serum Blush, 5 ml | Rs. 499 | Rs. 99.80 |
Multi-packs do most of the work. Four of the six cheapest rates above come from packs rather than single bottles - Mamaearth's Rs. 450 three-pack of 50 ml sunscreens is Rs. 3.00 a gram against Rs. 6.24 for the single 80 g tube, and its Rs. 998 two-pack serum is Rs. 16.63 a millilitre against Rs. 33.27 for the single. On both these stores the pack size, not the brand, is usually the bigger lever on what you spend.
What Each Brand Actually Sells
The catalogues are shaped differently, and that matters more than any single price. Dot & Key is a face-skincare specialist: 33 sunscreen variants, 13 serums, 14 moisturisers, 13 face washes - and exactly one shampoo in the whole feed. Sixty-eight of its 206 variants are combos.
Mamaearth is a full-range family brand. The same feed carries 26 face cleansers, 23 body lotions, 20 moisturisers, 17 shampoos, 27 lipsticks and a baby range, alongside 44 combos. Its entry prices are also far lower - it sells 10 g and 20 ml minis from Rs. 49 to Rs. 99, where Dot & Key's face skincare effectively starts at Rs. 249. Those minis are the most expensive way to buy Mamaearth per unit, but they are the cheapest way to try it.

How we read this, and what we cannot tell you
Both catalogues were read on 18 August 2026 from the brands' own Shopify feeds at /products.json: 150 products and 206 priced variants from dotandkey.com, 250 and 250 from mamaearth.in. Volumes are taken from each product's own title - '175 ml', '80 g', '(Pack of 2)' - and multi-packs are multiplied out, so a Rs. 998 listing described as 30 ml Pack of 2 is priced here as 60 ml. Every per-millilitre and per-gram figure is our arithmetic on those two stated numbers. Products whose titles state no volume, and every combo, are excluded from the per-unit tables because we cannot compute a rate for them honestly.
What we cannot tell you: whether either brand's prices differ on Nykaa, Amazon or its own app, which they often do; whether any product is in stock; what a coupon code does to these totals, which we did not test at checkout; and anything at all about formulation, efficacy, irritation or suitability for your skin. Comparing Rs. 2.49 a millilitre of one face wash against Rs. 2.85 of another tells you about price and nothing about what is in the bottle - ingredient lists, SPF ratings and concentration claims quoted here are the brands' own. We have not bought, used or tested any product on this page, and nothing here is dermatological advice.
Which Brand Should You Buy From?
- Face wash and serum: Dot & Key. Its face washes run Rs. 2.14 to Rs. 3.69 a millilitre against Mamaearth's Rs. 2.33 to Rs. 4.95, and its 13 serums sit in a 36 per cent band where Mamaearth's six span a factor of six.
- Moisturiser and shampoo: Mamaearth. Rs. 2.25 to Rs. 4.99 a gram on moisturiser against Dot & Key's Rs. 3.42 to Rs. 8.25, and 17 shampoos against one.
- Sunscreen: close, so buy on format. Medians are Rs. 7.98 and Rs. 8.90 a gram. What separates them is packaging - Dot & Key's Rs. 595 20 g stick is Rs. 29.75 a gram, the most expensive sunscreen either brand sells.
- Buy the multi-pack if you already know the product. Mamaearth's three-pack sunscreen halves the per-gram rate against its own single tube; its two-pack serum halves the per-millilitre rate.
- Use the Rs. 49 to Rs. 99 minis to try, not to save. They are the dearest units in Mamaearth's catalogue and the cheapest entry into it - both things at once.
- Check the coupon page before checkout on either. With no MRP and no badge on either store, a store code is the only discount available on these prices.
Zoutons Verdict
These two are not really competing for the same basket, and the per-unit prices say so. Dot & Key is a face-skincare specialist that prices tightly and predictably - 13 serums inside a 36 per cent band, face washes from Rs. 2.14 a millilitre - and sells exactly one shampoo. Mamaearth is a household range with 17 shampoos, 23 body lotions, a baby line and 27 lipsticks, and it is cheaper per unit on moisturiser and hair.
The thing both do well, and that almost nothing else we read this month does, is publish a price without a fake number beside it. Zero of 206 Dot & Key variants and zero of 250 Mamaearth variants carry a compare-at price. There is no badge to decode here - which means the only way to spend less is to buy the bigger pack, and on both stores that is worth roughly half the per-unit rate.
Frequently Asked Questions
Is Dot & Key cheaper than Mamaearth?
It depends entirely on the category, and we compared them per millilitre and per gram from both brands' own product feeds on 18 August 2026. Dot & Key is cheaper on face wash, with 13 SKUs from Rs. 2.14 to Rs. 3.69 a millilitre against Mamaearth's 28 SKUs from Rs. 2.33 to Rs. 4.95, and it is more consistent on serum, where its 13 SKUs sit between Rs. 18.33 and Rs. 24.95 a millilitre. Mamaearth is cheaper on moisturiser, at Rs. 2.25 to Rs. 4.99 a gram against Dot & Key's Rs. 3.42 to Rs. 8.25, and on shampoo, where it has 17 SKUs from Rs. 1.25 a millilitre against Dot & Key's single shampoo at Rs. 1.98. On sunscreen the two are close - medians of Rs. 7.98 and Rs. 8.90 a gram. Prices on direct-to-consumer stores change without notice.
Why do Dot & Key and Mamaearth not show any discount?
Because neither publishes a compare-at price on its own store. In the feeds we read on 18 August 2026, zero of Dot & Key's 206 priced variants and zero of Mamaearth's 250 carried a struck-through figure above the selling price. That is genuinely unusual: on marketplace shelves and on most other direct-to-consumer beauty sites we read, the great majority of listings sit permanently below a stated MRP. The practical consequence is that there is no badge to decode and no 'sale' to wait for on either store's own site - the price is the price. It also means the two levers that do lower your bill are pack size, which on both stores is worth roughly half the per-unit rate, and a store coupon code where one is live.
Which is the cheapest sunscreen from Dot & Key or Mamaearth?
Per gram, Mamaearth's Mineral Based Sunscreen sold as 50 ml packs of two or three - Rs. 300 for 100 ml or Rs. 450 for 150 ml, which is Rs. 3.00 a millilitre either way. Its single 80 g Vitamin C Daily Glow tube at Rs. 499 is Rs. 6.24 a gram, so the pack halves the rate. On the Dot & Key side the cheapest is the Watermelon Cooling Sunscreen Body Spray at Rs. 595 for 110 ml, or Rs. 5.41 a millilitre, followed by its 80 g face sunscreens at Rs. 595, or Rs. 7.44 a gram. The most expensive sunscreen either brand sells is Dot & Key's 20 g Strawberry Sunscreen Stick at Rs. 595, which works out to Rs. 29.75 a gram - nearly ten times the cheapest option here, for a format you can carry in a pocket.
Are the Rs. 49 Mamaearth minis good value?
They are the cheapest way into the brand and the most expensive way to buy it. A 10 g sunscreen mini at Rs. 49 works out to Rs. 4.90 a gram, which is more than the Rs. 3.00 a gram you pay on the three-pack, and a 20 ml face wash at Rs. 99 is Rs. 4.95 a millilitre against Rs. 2.40 for the 250 ml bottle - roughly double in both cases. That is the normal trade for a trial size and it is not a criticism: spending Rs. 49 to find out whether a sunscreen suits your skin is obviously better than spending Rs. 499 to find out the same thing. Just do not buy several minis believing you are economising. Once you know the product, the large size or the multi-pack is where the saving is.
Which brand is better for a full skincare routine?
For a face-only routine, Dot & Key covers it more completely and prices it more predictably: 33 sunscreen variants, 13 serums, 14 moisturisers and 13 face washes in the feed we read, with tight per-unit bands in each. For a household - hair, body, baby, and colour cosmetics alongside face - Mamaearth is the only one of the two that covers it at all, with 17 shampoos, 23 body lotions, 26 face cleansers, a baby range and 27 lipstick variants, against Dot & Key's single shampoo and no colour range in this feed. Neither of those observations is about which products work better, which no price feed can tell you and which this page does not claim to judge - it is about which catalogue can fill your basket without a second order.
Prices & codes last verified: 18 August 2026
Every price on this page was read on 18 August 2026 from each brand's own Shopify product feed at /products.json: 150 products and 206 priced variants from dotandkey.com, 250 products and 250 priced variants from mamaearth.in. The statement that neither brand publishes a compare-at price is what those feeds returned on that date and applies to the brands' own storefronts only - prices and promotions on Nykaa, Amazon, a brand app or in physical retail may differ, and we have not checked those. Volumes are taken from each product's own title and multi-packs are multiplied out; every per-millilitre and per-gram figure is our arithmetic on those two stated numbers rather than a figure either brand publishes. Products whose titles state no volume, and all combos, are excluded from the per-unit tables because no honest rate can be computed for them. Category counts are our own classification of each brand's product titles and product types. This page compares published prices only. It makes no claim about formulation, efficacy, SPF performance, irritation, ingredient quality or suitability for any skin type; ingredient and SPF descriptions are the brands' own wording, reported and not endorsed; and nothing here is dermatological or medical advice. We have not purchased, used or tested any product mentioned. Prices on direct-to-consumer stores change without notice - check the product page before you pay. Zoutons may earn a commission if you buy through links on this page; it does not change what you pay, and nothing here was reviewed or approved by Dot & Key or Mamaearth.
