![SPF 50 sunscreens from Minimalist, mCaffeine and Dot & Key, the three brands compared in this September 2026 price read, shown as the brands' own product photographs]()
Three Indian skincare brands, three own-brand stores, and three completely different answers to the question of what a discount is. We read all of them on 15 September 2026 — 470 in-stock variants between them — and recorded every selling price, listed price and pack size.
Minimalist discounts every single variant in its catalogue, almost all of them by exactly five percent. mCaffeine discounts a fifth of its shelf, at twenty to thirty. Dot & Key discounts thirteen items out of a hundred and eighty-one, twelve of which are lip balms. Then we divided each price by the number of millilitres or grams on the label, and the ranking those badges imply fell apart completely.
📊 Three catalogues read 15 September 2026
100% vs 19% vs 7% of variants discounted
And the deepest badges sit on the dearest serum per millilitre
📅 Update log:
15 Sep 2026 — first published. Every price, listed price and pack size on this page was read from beminimalist.co, mcaffeine.com and dotandkey.com on 15 September 2026, logged out, in India. D2C brands change prices and promotions frequently; we re-read these catalogues periodically and log what has changed here.
Three brands, three completely different meanings of 'on sale'
We read all three catalogues on 15 September 2026 — every in-stock variant, with its selling price, its listed price and its stated size — and the first thing that falls out is that the word discount is doing three different jobs.
Minimalist marks down everything. All 97 in-stock variants in the read carry a struck-through price, and 83 of them are at exactly 5 percent. A five percent cut that applies to the entire catalogue and never lifts is not really a sale; it is a list price written twice.
mCaffeine marks down a fifth of the shelf, and does it properly. Thirty-seven of 192 variants are discounted, at 20, 25 or 30 percent. Those are real reductions on the products that carry them — and 155 variants carry none.
Dot & Key barely discounts at all. Thirteen of 181 variants, all at 15 percent, and twelve of the thirteen are lip balms. Everything else on that store sells at the brand's own listed price.
| Brand | In-stock variants | Discounted | Share | What the badge says |
|---|
| Minimalist | 97 | 97 | 100% | 5% on 83 of them; 10% on five, 15% on seven |
| mCaffeine | 192 | 37 | 19% | 20% on 14, 25% on 11, 30% on five |
| Dot & Key | 181 | 13 | 7% | 15% on all thirteen — twelve lip balms, one moisturiser |
Why this matters: a shopper comparing these three by badge size would conclude that Minimalist is always on sale, mCaffeine sometimes has real deals, and Dot & Key never discounts. All three are true, and none of them tells you which brand is cheaper for the thing you are actually buying. For that you have to divide by the size on the label, which is what the rest of this page does.
SPF 50 face sunscreen: the same size, three prices
Sunscreen is the cleanest comparison of the three categories here, because all three brands sell an SPF 50 face product in a 50-unit size and all three publish the size on the label.
Minimalist's 50g is Rs. 379 after its standing 5 percent — Rs. 7.58 a gram. mCaffeine's 50ml Green Tea sunscreen is Rs. 399 with no discount, Rs. 7.98 a millilitre. Dot & Key's 50g tubes are Rs. 445, Rs. 8.90 a gram. The spread between cheapest and dearest is 17 percent, which is larger than any of the badges involved.
The bigger gap is the one inside each brand. Minimalist sells the same sunscreen in 30g, 50g and 100g, and the 100g at Rs. 664 works out at Rs. 6.64 a gram against Rs. 7.90 for the 30g — a 16 percent swing for choosing a size, on a product where the 5 percent badge is identical across all three. Dot & Key's 80g is Rs. 7.44 a gram against Rs. 8.90 for its 50g. Neither store describes the larger size as a saving anywhere.
| Sunscreen | Minimalist | mCaffeine | Dot & Key |
|---|
| SPF 50 face sunscreen, 50g or 50ml | Rs. 379 — Rs. 7.58 a gram | Rs. 399 — Rs. 7.98 a ml | Rs. 445 — Rs. 8.90 a gram |
| The largest face size each brand sells | 100g, Rs. 664 — Rs. 6.64 a gram | 50ml is the largest face tube, Rs. 399 | 80g, Rs. 595 — Rs. 7.44 a gram |
| The smallest size on the shelf | 30g, Rs. 237 — Rs. 7.90 a gram | 50ml, Rs. 399 — Rs. 7.98 a ml | 20g stick, Rs. 595 — Rs. 29.75 a gram |
⚠️ One honest caveat on this table. mCaffeine also sells a 200ml Brightening Sunscreen lotion at Rs. 549, which is Rs. 2.75 a millilitre and by far the cheapest sun protection per unit named on this page. It is a body-sized lotion rather than a 50ml face tube, so we have kept it out of the like-for-like row rather than letting it win a comparison it is not in. Dot & Key's 110ml body spray at Rs. 5.41 a millilitre sits in the same category. If you are covering arms and legs, both are far better value than any face tube here.
Face serum: the badge and the price point in different directions
All three brands sell 30ml face serums, which makes this the second clean comparison. Minimalist's cheapest is Rs. 522 (Rs. 17.40 a millilitre), Dot & Key's is Rs. 550 (Rs. 18.33) and mCaffeine's only 30ml face serum is Rs. 699 (Rs. 23.30).
That last number is the one worth sitting with. mCaffeine runs the deepest badges of the three brands — 20 to 30 percent where it discounts — and its face serum is the most expensive per millilitre on this page, at full price. A brand's discount policy and its price level are separate decisions, and shoppers routinely read the first as evidence about the second.
Depth of range differs too. Dot & Key lists eight 30ml face serums in this read and Minimalist six; mCaffeine lists one. If you want to choose between actives rather than between brands, that is a more useful fact than any percentage.
| Serum | Minimalist | mCaffeine | Dot & Key |
|---|
| Cheapest 30ml face serum | Alpha Arbutin 2%, Rs. 522 — Rs. 17.40 a ml | Green Tea & 15% Vitamin C, Rs. 699 — Rs. 23.30 a ml | Cica + 2% Salicylic, Rs. 550 — Rs. 18.33 a ml |
| The brand's vitamin C serum, 30ml | Vitamin C 10%, Rs. 664 — Rs. 22.13 a ml | Green Tea & 15% Vitamin C, Rs. 699 — Rs. 23.30 a ml | 10% Vitamin C + E, Rs. 695 — Rs. 23.17 a ml |
| Number of 30ml face serums in the read | Six | One | Eight |
Face wash, moisturiser and shampoo: the no-discount brand wins two
Here the pattern inverts. Dot & Key, which discounts almost nothing, has both the cheapest face wash and the cheapest face moisturiser per unit on this page — five gel washes at Rs. 249 for 100ml (Rs. 2.49 a millilitre, or Rs. 2.14 if you take the 175ml) and a Barrier Repair moisturiser at Rs. 3.42 a gram in its 175g size.
mCaffeine's cheapest 100ml face wash is Rs. 299, and its cheapest face moisturiser is a 50ml jar at Rs. 7.98 a millilitre — more than twice Dot & Key's rate for a comparable job, on a brand whose badges are the deepest here. Minimalist publishes no 100ml face wash in this read at all, so it sits out of that row rather than losing it.
And then shampoo goes the other way again: mCaffeine's 250ml Caffexil shampoo at Rs. 349 is Rs. 1.40 a millilitre, the cheapest per-unit rate in this entire read, against Rs. 1.98 for Dot & Key's 200ml and Rs. 2.00 for Minimalist's 250ml. No brand here is cheapest at everything, and no brand's badge policy predicts where it will win.
| Category | Minimalist | mCaffeine | Dot & Key |
|---|
| Cheapest 100ml face wash | No 100ml face wash in this read | 2% Salicylic + Niacinamide, Rs. 299 — Rs. 2.99 a ml | Five at Rs. 249 — Rs. 2.49 a ml |
| Cheapest face moisturiser per unit | Vitamin B5 10%, 100g Rs. 569 — Rs. 5.69 a gram | Green Tea oil-free, 50ml Rs. 399 — Rs. 7.98 a ml | Barrier Repair, 175g Rs. 599 — Rs. 3.42 a gram |
| Shampoo, 200–250ml | Bond Repair 3.5%, 250ml Rs. 499 — Rs. 2.00 a ml | Caffexil, 250ml Rs. 349 — Rs. 1.40 a ml | Moringa & Argan, 200ml Rs. 395 — Rs. 1.98 a ml |
Four ways a skincare discount can mean nothing
Everything above reduces to one habit: convert the price to a rate before you compare anything. These are the four shapes that most often defeat a quick glance, all four of them drawn from these three catalogues on the day we read them.
| The trap | What it looks like | What the arithmetic says |
|---|
| A permanent five percent | Every Minimalist variant in this read shows a struck-through price | A discount that never comes off is a list price with two numbers on it |
| A pack of two | Dot & Key sells Pack of 2 bundles across the catalogue | Every one we checked is exactly twice the single; the lip balm pack is Rs. 498 against Rs. 424 for two singles |
| A deep badge on a small jar | mCaffeine's 20–30% badges | A 25% cut on a 50ml jar can still cost more per ml than an undiscounted 100g tub |
| The size you did not compare | Two sizes of one product, one price each | Minimalist's sunscreen is Rs. 7.90 a gram at 30g and Rs. 6.64 at 100g — a 16% swing inside one product |
How we read the three catalogues, and what we left out
Each brand publishes its full product list at a public /products.json endpoint on its own Shopify store. We read all pages of each on 15 September 2026 as a logged-out visitor in India, kept only in-stock variants with a price above zero, and recorded the selling price, the listed (compare-at) price and the size stated on the variant or product title.
Per-unit rates are ours: selling price divided by the stated millilitres or grams. Where a product states no size we have no rate for it and have not estimated one. Combo listings, kits, free-gift sachets and multi-packs are excluded from the category tables because a bundle price is not comparable with a single product, though the Dot & Key pack arithmetic is described in the traps table above. Grams and millilitres are not interchangeable and we have not converted between them; where a comparison crosses the two units the table says so.
We did not buy, open or test anything. SPF and PA ratings, percentage actives, ingredient claims and any statement about skin-type suitability are each brand's own. Marketplace listings for the same products — on Nykaa, Amazon, Flipkart or Myntra — carry different prices, different sellers and different offers, and none of them is covered here.
So which of the three should you buy from?
On this read, and only on price per unit: Dot & Key for face wash and face moisturiser, Minimalist for sunscreen and serum, mCaffeine for shampoo and for body-sized sun protection. Nobody wins the aisle.
The more portable conclusion is about the badge. The brand that discounts every single product is cheapest at two of six categories; the brand that discounts almost nothing is cheapest at two others; and the brand with the deepest badges is the dearest per millilitre in the category most shoppers buy first. If you take one habit from this page, make it the division: price divided by the number on the label, before anything else.
Frequently Asked Questions
Is Minimalist always on sale?
Effectively, yes — and that is the point. All 97 in-stock variants we read on 15 September 2026 carried a struck-through price, and 83 of them were at exactly 5 percent. Seven were at 15 percent and five at 10. A discount that applies to the entire catalogue at a uniform rate is closer to a pricing convention than to a sale, and it should not be read as evidence that a product is temporarily cheap. What matters is the rate after the cut: Minimalist's 100g SPF 50 sunscreen at Rs. 664 is Rs. 6.64 a gram, the cheapest face sunscreen per unit in this read.
Which is cheaper, Dot & Key or mCaffeine?
It depends entirely on the category, and the discount badges point the wrong way. Dot & Key is cheaper on face wash (Rs. 2.49 a ml against Rs. 2.99), on face moisturiser (Rs. 3.42 a gram against Rs. 7.98 a ml) and on 30ml face serum (Rs. 18.33 a ml against Rs. 23.30), despite discounting almost nothing. mCaffeine is cheaper on shampoo (Rs. 1.40 a ml against Rs. 1.98) and sells a 200ml sunscreen lotion at Rs. 2.75 a millilitre that has no equivalent in Dot & Key's face range.
Which brand has the cheapest SPF 50 sunscreen?
Of the face sunscreens we could match like for like, Minimalist: Rs. 379 for 50g, or Rs. 7.58 a gram, against mCaffeine's Rs. 399 for 50ml (Rs. 7.98) and Dot & Key's Rs. 445 for 50g (Rs. 8.90). Take Minimalist's 100g at Rs. 664 and the rate drops to Rs. 6.64 a gram, the cheapest face sunscreen in this read. Note that grams and millilitres are not the same unit and we have not converted between them. If you want sun protection for arms and legs rather than the face, mCaffeine's 200ml lotion at Rs. 2.75 a millilitre is far cheaper than any face tube here.
Are the pack-of-two bundles worth buying?
Not on Dot & Key, on the day we read it. Every Pack of 2 we checked is priced at exactly twice the single — face wash Rs. 498 for two Rs. 249 bottles, sunscreen Rs. 890 for two Rs. 445 tubes, serum Rs. 1,390 for two Rs. 695 bottles. On lip balms it is worse than neutral: the Pack of 2 is Rs. 498 while two discounted singles cost Rs. 424, so the bundle is Rs. 74 dearer for the same two balms. The saving that does exist on all three stores is the larger size of a single product, which is never labelled as a saving.
Do these prices match Nykaa, Amazon or Myntra?
Not necessarily, and this page does not claim they do. Everything here was read from each brand's own store on 15 September 2026. Marketplace listings for the same products are sold by different sellers, carry their own discounts, bank offers and delivery charges, and frequently price the same SKU differently — sometimes below the brand's own site, sometimes above it. If you are buying one product rather than a basket, it is worth checking both; if you are buying several, the brand's own store is usually the simpler comparison because every price on it is set by one seller.
Prices & codes last verified: September 15, 2026
Every selling price, listed price, discount percentage and stated pack size on this page was read on 15 September 2026 from the public product catalogues published by beminimalist.co, www.mcaffeine.com and www.dotandkey.com, as served to a logged-out visitor in India, with nothing purchased and no account used on any of the three sites. The per-millilitre and per-gram rates, the counts of discounted and undiscounted variants, the category comparisons and the characterisation of each brand's discount pattern are our own arithmetic and description applied to those published figures. Per-unit rates are calculated from the size each brand states on its own variant or product title; grams and millilitres are different units and have not been converted between, so a comparison that crosses them is indicative rather than exact and is labelled as such in the tables. Combination packs, kits, free-gift sachets and multi-packs are excluded from the category comparisons because a bundle price is not comparable with a single product. SPF numbers, PA ratings, 'broad spectrum' and 'in-vivo tested' claims, percentage concentrations of actives, ingredient lists and any statement about suitability for a skin type or condition are each brand's own published claims and were not verified by us; nothing on this page was purchased, opened, applied, assayed or tested, no product was compared for efficacy, texture, finish or tolerance, and nothing here is a test result or a clinical finding. Nothing on this page is medical or dermatological advice; sunscreen, retinoid and acid products should be chosen with professional guidance where you have a skin condition. Describing a brand's discounting as uniform, shallow or absent reports the prices displayed on one day and alleges no wrongdoing by Minimalist, mCaffeine, Dot & Key or any other brand named; none of the three was contacted for comment and none has endorsed this comparison. Prices on marketplaces such as Nykaa, Amazon, Flipkart and Myntra are set by their own sellers, differ from the prices reported here and are outside the scope of this page. Prices, sizes, formulations, promotions and stock change without notice, and readers should confirm the current price and size on the brand's own product page before buying. Zoutons may earn a commission if you buy through links on this page; it does not change what you pay and does not affect what is reported here.
