Your makeup face chart, drawn on your own selfie

Hey, it's Cindy 🌱 A face chart is what a makeup artist sketches before they touch your face, and this gets you yours from one selfie.

before you paste anything

Take the right selfie

The whole thing runs on this one photo, and it is the only part you can really get wrong. It takes a minute.

  1. Stand facing a window. Daylight on your face, no overhead light, no ring light. Overhead light invents shadows that are not yours, and the chart will place contour around them.
  2. Bare face, or as close as you can get. Foundation hides your real undertone, which is the thing you actually want it to read.
  3. Hair fully off your face. Pull it back. It needs your hairline and your jaw to work out face shape.
  4. Straight on, neutral expression, eyes open. No tilt, no angle, no smile. A relaxed face is what makeup gets applied to.
  5. Take three and pick the flattest one. Not the prettiest. The most evenly lit, straightest one.
Any plan works. ChatGPT Images is available on all tiers, so you can do this on the free plan. You upload an existing photo and describe the change you want, which is exactly what this prompt does.

The face chart prompt

Attach your selfie first, then paste this. It runs in three parts: a written read of your features, then the chart, then the finished look on you.

💄 the full face chart
Act as a professional makeup artist and create a personalised face chart from my selfie.

Step 1, in a few short lines: tell me my face shape, eye shape, lip shape and skin undertone (warm, cool or neutral), and what in the photo told you each one.

Step 2: create one image, a clean beauty-board infographic, 4:5. On the left, my original photo with thin labelled lines and soft coloured zones showing exactly where to place contour, blush, highlighter, brow shape (start, arch and tail points), eyeshadow, eyeliner shape and lip liner. On the right, a swatch column with 3 shade families per category that suit my undertone, labelled in plain words like "soft rosy mauve", not brand names.

Step 3: create a second image of me wearing the finished look, split into two halves labelled "everyday" (soft and skin-like) and "going out" (defined eyes, deeper lip).

Rules: keep my face, features, skin tone, skin texture and proportions exactly the same. Do not slim, reshape, lighten or smooth my face. Only add makeup.

Finish with a numbered application order I can follow in 10 minutes.
If steps 2 and 3 come back as one image. It happens. Reply with "now do step 3 as a separate image" and it will. This is not a sign the prompt failed, models just combine image steps sometimes.

what you get back

How to actually read the chart

A face chart looks like a diagram at first. Here is what each part is telling you to do.

The contour and blush zones These are placement, not shape-changing. Blush placed higher reads youthful and awake, placed lower and outward reads softer. The chart picks based on where your cheekbone actually sits.
The three brow points Start, arch, tail. These are the only three measurements that matter, and they are set by your eye spacing and your brow bone, which is why a brow shape that suits one person looks odd on another.
The liner shape The line's angle and where it thickens is driven by your eye shape: hooded, downturned, almond, round. Same product, completely different result.
The swatch column Three shade families per category rather than one, because your skin changes through the year. Plain words rather than brand names so you can match them at any counter.

Make it useful, not just pretty

The chart is the fun part. These are the ones that save you money.

1. Shop from what you already own. Send this straight after the chart, in the same chat.

🧺 use my existing makeup bag
Here is a photo of everything currently in my makeup bag. Using the face chart and undertone you just worked out for me, go through what I own and sort it into three groups: what already suits me and should be in my daily routine, what suits me but I am probably using in the wrong place, and what genuinely does not work with my undertone.

For anything in the middle group, tell me exactly where to move it to based on my chart, for example a blush I am placing too low or a bronzer I should be using as an eyeshadow instead.

Then give me a short list of what is actually missing from my kit to complete the everyday look, described as shade families rather than products, and tell me roughly what each one usually costs so I know what I am walking into.

2. Practise before the event. Give it an occasion and it adjusts the whole plan for the lighting and the photos.

🥂 the occasion version
Using my face chart and undertone, adapt the look for a specific occasion: [describe it, for example an evening wedding indoors with a lot of flash photography, or a daytime job interview under office lighting].

Tell me what changes and why, covering base finish, blush placement and intensity, eye definition, and lip depth. Be specific about the lighting, for example whether flash photography will flatten my features and what that means for how much contour and highlighter I should use.

Then create one image of me wearing that adapted look so I can see it before I commit, keeping my face, features, skin tone, skin texture and proportions exactly as they are.

Finish with a timing plan: what to do the night before, what to do an hour before, and the two things most likely to slide by hour four so I know what to carry with me.

3. Turn it into a ten-minute routine you will actually do.

⏱ the ten-minute version
Strip my everyday look down to the shortest version that still looks intentional, assuming I have ten minutes and I am not wearing glasses or false lashes.

Give me an ordered list of no more than six steps, each with the product type, where it goes on my face according to my chart, and one sentence on the technique that makes the difference for my features specifically.

Then tell me which single step I should never skip if I am down to five minutes, and which one is the most forgiving if my hands are unsteady. Explain both choices in one line each so I understand the logic rather than just following instructions.

when it misbehaves

The four fixes

  1. 🫥 It changed your face. The rules paragraph is there to stop this, but it slips sometimes. Reply "you changed my face, regenerate keeping my exact features, jaw width, nose and skin texture, only adding makeup" and it will correct.
  2. 🔤 The labels are unreadable. Common on the swatch column. Ask for "the swatch column only, as its own image, larger text, 4:5" and use that version.
  3. 🤷 The undertone reading feels wrong. Usually the lighting. Retake in daylight and try again, and tell it what colour your veins look like at your wrist and whether silver or gold jewellery suits you better. Both are real signals and it will use them.
  4. 🎨 The chart is generic. If the placement looks like every face chart you have ever seen, push back: "explain why you placed the blush and the brow arch there for my face specifically, and redo the chart if the reasoning does not hold". Making it justify itself usually produces a better second attempt.

the honest bit

What this is and what it is not

This is a placement guide. It tells you where things go on your particular face and which shade families sit well against your undertone, and it is genuinely good at that, because placement is geometry and geometry is something a model can read from a photo.

It is not a verdict on how you look, and it is not a substitute for actually swatching in person. Screens lie about colour, so treat the shade families as a shortlist to test rather than a shopping list to buy. And the rendered "finished look" images are a preview, not a promise: your own hands, your own products and your own skin will land somewhere near it, not exactly on it.

One thing worth doing. Save the step 1 text answer somewhere, not just the images. Your face shape, eye shape and undertone do not change, so that paragraph is the reusable part. Every future makeup question you ask can start with pasting it back in.
