## What is Serum?

Serum organises the skincare you already own.

Tell it what is on your shelf and it works out the order, the timing, and what should never share a night. Retinoid on Monday, acid on Thursday, and four gentle evenings in between. No guessing, no starting again every time you buy something.

WHAT IT ACTUALLY DOES

Builds your week. Every product goes to morning, evening, or both, capped at the frequencies its ingredients are usually used at. Retinoids three nights, AHAs two. Everything is spaced so nothing collides.

Runs the routine. One step at a time, in the right order, with a timer that paces you rather than rushes you. A soft chime marks each step while you are watching. Add or take off five seconds and Serum keeps that pace for every step like it from then on.

Carries on when you put the phone down. Lock your screen mid-routine and the ritual follows you: a notification at the end of every step, and a live countdown on your lock screen and Dynamic Island. A fifteen minute mask becomes fifteen minutes of doing something else.

Watches your bottles. Serum estimates what is left from how often you actually use each product, and tells you before something runs out mid-week.

Pauses for treatments. Had a peel or a laser session? Log it and Serum holds back your retinoids and acids while your skin recovers, then eases them back in. Your sunscreen stays, because resurfaced skin needs it more.

Remembers. Photos, notes, and a timeline of what your skin has actually been doing, which is the only way to tell whether something is working.

WHAT IT IS NOT

Serum does not rank products or tell you what your skin needs. It does not diagnose anything. It arranges what you have already chosen and keeps the strong steps apart.

FREE, AND WHAT IS NOT

Free forever: adding products, building your regimen, conflict detection, the routine player, reminders, streaks, five recent journal entries, and logging a professional treatment. Building your schedule is a safety calculation, so it is never paywalled. Neither is the recovery pause after a treatment.

Serum Premium adds your whole shelf scheduled rather than five products, guided home spa sessions and a monthly nudge to take one, milestones as you reach them, the products you used in any finished routine, full history, before and after comparison, trends, suggestions for what is missing from your shelf, steps you can switch off, rotation that leans on your own journal notes, and multiple rituals: a shorter week for travel, a gentle one for a flare-up, and weeks you build and name yourself.

PRIVACY

Your photos never leave your phone. There is no account, no server holding your shelf, and nothing we can look at. Serum shares usage information about the kinds of products people own, not tied to your name or email, which you can switch off on the first screen or any time afterwards.

Serum is not medical advice. Patch test anything new, follow the instructions on the bottle, and see a dermatologist for anything persistent.

### How does Serum handle privacy?

## Version history (last 5 releases)

### 1.4 — 2026-09-24

Swap a product for today, and a routine with room to breathe.

NEW
• Swap for this session. Own more than one moisturiser, serum or cleanser? With Serum Premium, tap the swap icon on a step in Today to use a different one this time. Serum only offers what is safe alongside the rest of your routine, and your week carries on exactly as planned.

IMPROVED
• More time on every step. Each step now allows an extra 20 seconds, so there is time for a product to settle before you reach for the next.

• Day and night products stay where they belong. A day cream is no longer offered at night, nor a night serum in the morning.

• Three firm pulses when a step ends, so you feel it with your phone on silent.

• Clay is now a texture you can choose when adding a product.

### 1.3 — 2026-09-21

Meet Smart Scan: add a product just by pointing your camera at it.

NEW
• Smart Scan. On Add product, tap Smart Scan and hold the front of the bottle in frame. Serum recognises the product, already knows what is in it, and adds it to your shelf in one tap. No typing, no ticking ingredients, and your week is spaced properly from the very first night.

• Smart when it is stumped, too. If Serum has not met the product yet, it still reads the brand and the name off the bottle and fills them in for you.

• Private by design. The label is read on your phone. Nothing is photographed.

• A catalogue six times the size. More than 800 products from almost 150 brands, from the pharmacy shelf to the beauty counter, and many can now be found under more than one name.

FIXED
• A product with several strong actives in one bottle, such as a retinoid with vitamin C, or a peel pad with more than one acid, could be left out of your week entirely. It now gets an evening to itself.

• Benzoyl peroxide washes are now recognised, and kept off your retinoid nights.

### 1.2 — 2026-09-17

Serum Pro is now Serum Premium. Same subscription, same price, new name.
One new feature with it, a tidier Milestones screen, and five fixes from the first
days of real use.

NEW
• See what you used. Open any finished routine on your Progress timeline and it
  shows every product that was in it, including the ones you skipped. Serum Premium.

• Your milestones now sit in a row you can swipe through, with the one you are
  closest to first. They no longer push the rest of your progress down the screen. Serum Premium.

FIXED
• The Shelf scrolls properly. A gentle swipe starting on a product card used to do
  nothing, which made a long shelf hard to move through.

• Your routine always shows all six steps. A step that is empty now says why
  instead of quietly disappearing, so the shape of your routine stays the same
  whatever is filling it that day.

• Anything on your shelf that is not in this week's plan says so, rather than
  going missing without explanation.

• A step that is waiting for later in the day now says so. It used to say it was
  not happening tonight even when it was.

• On the free plan, the five products Serum schedules are now chosen to cover your
  routine rather than by category order. Two cleansers no longer crowd out your
  serum.

### 1.1 — 2026-09-16

A smarter routine, and a good number of features people asked for.

YOUR ROUTINE IS NOW SIX STEPS
Cleanse, tone, essence, serum, moisturise, and then sunscreen in the morning or eye
cream at night. Your products still rotate through those steps across the week, and
a treatment, an oil cleanser or a face oil fills the step it belongs to rather than
adding another one. Sunday evening adds an exfoliant or a mask.

NEW
• Milestones. Every streak, home spa and stretch of good skin you have kept up,
  with the date you reached it. On the Progress tab.
• Switch a step off before you start a routine, and any step you do not own yet is
  skipped for you.
• Smarter product rotation. When your notes say your skin has been dry, Serum leans on your more hydrating
  products. Nothing is added and nothing is taken away.
• A quiet nudge when it has been a month without a home spa.
• Missing a step? Serum says so on Today, and helps you find one.
• Suggest a feature, under the lock icon on Today. We read all of them.

FIXED
• The Ulta reorder link led to a dead page. It works again.
• The shelf would not scroll if your finger started on a product card.
• An evening with something running low sent one notification instead of two, so
  the routine reminder went missing.
• "Add a product" moved to the top of the shelf, where a long list cannot bury it.
• "Not sure which one? Check the label" now sits above the ingredient list rather
  than under it.
• The Pro sparkles shimmer instead of pulsing, and the app icon holds its shape in
  glass and tinted modes.
