Microblading Step-by-Step: What Really Happens During Your Session
If you’ve decided microblading might be right for you, the next question is usually the same: what actually happens in the chair? Most online content either glosses over the details or shows graphic close-ups that put people off entirely. Neither helps you make an informed decision.
This guide walks you through a real microblading session from the moment you arrive at the studio to the moment you leave — and then through the four weeks of healing that follow. We’ll cover what each step feels like, how long it takes, what your artist is doing and why, and what you can do to get the best possible result.
By the end, you’ll know exactly what to expect when you book your first microblading appointment. No surprises, no marketing spin — just the full picture from a Knightsbridge studio that has completed hundreds of brow services.
Before We Begin — What Microblading Actually Is
Microblading is a manual permanent makeup technique that uses a hand-held tool with a row of tiny needles arranged in a fine blade. Your artist uses this blade to make precise, hair-thin cuts in the upper layers of the skin, depositing pigment into each stroke to create the appearance of natural brow hairs.
The result, done well, is brows that look fuller, more defined, and beautifully shaped — without looking “drawn on.” Microblading typically lasts 1–2 years before requiring a colour boost.
For broader context on how microblading compares to other techniques, see our complete guide to permanent makeup or our breakdown of microblading vs nano brows.
Step 1 — The Pre-Appointment Consultation (Days or Weeks Before)
Microblading should never begin on the day you first walk in. A proper consultation comes first — usually 1–2 weeks before your treatment.
During this 45–60 minute appointment, your artist will review your full medical history, assess your skin type (microblading suits normal-to-dry skin best), discuss the brow shape and style you’re hoping for, show you portfolio work that matches your goals, explain pigment colour options based on your hair and undertones, walk you through the full process, healing, and aftercare, and confirm pricing and book your session.
This is also when your artist screens for contraindications — pregnancy, blood thinners, certain skin conditions — that would mean microblading isn’t appropriate.
Tip: Bring photos of brows you love (and brows you don’t). It’s the fastest way to align expectations with your artist.
Step 2 — Pre-Appointment Preparation (1 Week Before)
A week before your appointment, you’ll need to start preparing your skin and body for the best possible result. Avoid blood thinners including aspirin, ibuprofen, fish oil, and high-dose vitamin E (with your doctor’s approval). Avoid alcohol for 48 hours before — it thins the blood and increases swelling. Avoid caffeine on the morning of your appointment for the same reason. No retinoids, AHAs, or chemical exfoliants on the brow area for 7–10 days. No brow tinting, waxing, or threading for 3–5 days before. Avoid sun exposure and tanning — sunburnt skin can’t be worked on.
Eat a proper meal before you come, stay hydrated, and arrive with clean skin and no makeup on your brows.
Step 3 — Arrival and Final Design Review (15 Minutes)
When you arrive at the studio, the first thing your artist will do is reconfirm everything you discussed at consultation. You’ll fill in a final consent form, your artist will photograph your natural brows, and you’ll have one more conversation about the shape and style.
This isn’t a formality — it’s your last chance to refine anything before mapping begins.
Step 4 — Eyebrow Mapping (20–30 Minutes)
This is the most important step in the entire process, and where great microblading separates from average microblading.
Your artist uses precise measurement techniques to find the most flattering brow shape for your face. This involves measuring the distance between your eyes, nose, and brows, identifying the start point, arch, and tail of each brow using facial proportions, drawing the proposed shape in cosmetic pencil so you can see and approve it, and adjusting symmetry — your face isn’t perfectly symmetrical, and neither are your natural brows, so the artist creates the appearance of symmetry rather than mechanical mirror-image.
You’ll be handed a mirror. You’ll discuss. You’ll adjust. No needles touch your skin until you’ve approved the shape.
For a deeper look at how this works, see our guide to eyebrow mapping.
Step 5 — Numbing (20 Minutes)
Once the shape is approved, your artist applies a topical anaesthetic to the brow area. This is a cream or gel containing lidocaine and other numbing agents, left in place for around 20 minutes to fully take effect.
Most clients describe the sensation during microblading after numbing as a light scratching or pressure — not painful, but noticeable. A second, stronger anaesthetic is often applied partway through the procedure to keep you comfortable.
Step 6 — Pigment Selection and Mixing (5–10 Minutes)
While the numbing takes effect, your artist mixes the pigment shade for your brows. This is a fine art — your pigment is matched to your natural brow hair colour, your skin undertone (warm, cool, or neutral), how the pigment will heal (most pigments lighten 30–50% during healing), and your hair colour and overall colouring.
Cheap PMU often uses one or two off-the-shelf shades. Quality work involves custom-blending two to four pigments for every client.
Step 7 — The First Pass: Outline and Shape (20–30 Minutes)
Now the actual microblading begins. Your artist uses the manual blade to create the first set of hair strokes, following the mapped shape. The first pass focuses on defining the outline of the brow, establishing the direction and pattern of hair strokes, and creating the base layer of pigment.
You’ll hear a faint scratching sound. You may feel light pressure. The numbing handles the discomfort for nearly all clients — though everyone’s pain threshold is different.
This pass usually takes 20–30 minutes per brow.
Step 8 — The Second Pass: Density and Refinement (20–30 Minutes)
After the first pass, your artist cleans the area and applies a second numbing layer. Then comes the second pass — adding more strokes, building density, and refining the shape based on how the first pass settled into your skin.
Some clients need a third pass; some don’t. Your artist works to your skin’s response rather than to a fixed formula.
Step 9 — Final Review and Photography (10 Minutes)
Once the strokes are complete, your artist will clean your brows thoroughly, apply a final layer of pigment to saturate the strokes, and let you see the finished result.
Important to know: Your brows will look significantly darker and more defined immediately after treatment than they will once healed. This is normal. The pigment will lighten by 30–50% over the next four weeks as your skin heals.
Your artist will take “after” photos, walk you through aftercare instructions, and book your 6–8 week touch-up.
Step 10 — Aftercare (Days 1–30)
The work doesn’t end when you leave the studio. How you care for your brows over the next 30 days has a major impact on how well they heal and how long they last.
A brief overview of the healing timeline: Days 1–3, brows look dark, sharp, and slightly swollen. Days 4–7, light scabbing forms; brows start to look “crusty” (do not pick). Days 8–14, scabs flake off naturally; brows look very pale or patchy — this is the “ghosting” phase and is completely normal. Days 15–30, true colour gradually returns as pigment settles into the dermis. Week 6–8, touch-up appointment to refine and lock in results.
Key aftercare rules: keep brows dry for the first 7–10 days, no makeup on the area, no swimming or saunas, no picking or scratching, and apply the healing balm your artist provides exactly as directed.

Step 11 — The Touch-Up (6–8 Weeks Later)
The touch-up is not optional — it’s part of the treatment. At this appointment, your artist assesses how your skin held the pigment, fills any areas that healed unevenly, refines the shape now that the first session has settled, adjusts colour if any tones shifted during healing, and photographs the final result.
After the touch-up, your microblading is considered “set” — and you can expect 1–2 years of beautiful, low-maintenance brows.
How Long Does the Whole Microblading Session Take?
End to end, your microblading appointment will take 2.5–3 hours: 15 min arrival and final review, 20–30 min mapping and design approval, 20 min numbing, 5–10 min pigment mixing, 60–90 min microblading (two passes), 10 min final review and photography, and 15 min aftercare briefing.
Allow yourself the full afternoon. Don’t book anything stressful afterwards.
Common Questions About the Microblading Process
Does microblading hurt? Most clients rate the discomfort 2–4 out of 10 thanks to the numbing. Sensitivity varies, but it’s far less intense than people expect.
Can I drive home afterwards? Yes — there’s no sedation, just topical numbing.
Will I look strange immediately after? Your brows will look darker and more defined than they’ll heal — but they’ll look intentional, not shocking. Most clients go straight out for coffee afterwards.
What if I don’t like the result? Microblading is adjustable at your touch-up. A good artist will refine until you’re delighted. This is why choosing the right artist matters — see our guide to choosing the best microblading artist in London.
