Is Microblading Safe? What to Know Before You Book in London
Updated: 2 days ago
Microblading is one of the most popular semi-permanent beauty treatments in London — but it's also one that raises a lot of questions before booking. Is it safe? Does it damage your skin? Can anything go wrong?
These are sensible questions to ask before any cosmetic procedure, and they deserve straight answers rather than reassuring marketing copy.
The short answer: Yes, microblading is generally safe when it is done by a trained, experienced artist in a licensed, hygienic studio, on a suitable client. It does break the skin, so it carries the same kinds of risk as any cosmetic tattooing: infection, allergic reaction, uneven healing and, rarely, scarring. Most of these risks are reduced by the studio you choose and by following aftercare.
At a glance
What it is: a form of cosmetic tattooing that places pigment in the upper layers of the skin.
Healing: about two weeks for the skin to settle, with colour continuing to evolve for several weeks after.
Main risks: infection, pigment allergy, uneven healing, colour change and scarring. All are uncommon with a skilled artist.
Who should wait or avoid it: pregnancy, breastfeeding, active skin conditions in the brow area, and some medical conditions, assessed case by case.
How long it lasts: typically 12–24 months, depending on skin type and lifestyle.
What happens during microblading?
Microblading uses a fine, manual hand tool to create small incisions in the upper layers of the skin, into which pigment is deposited to create hair-like strokes. It is a form of cosmetic tattooing — which means it does break the skin, and all the hygiene and safety standards that apply to tattooing apply here too.
Understanding this is important. Microblading is not a surface-level treatment like tinting or lamination. It requires sterile equipment, proper training, a clean studio environment, and a thorough pre-treatment consultation.
Is Microblading Regulated in the UK?
Microblading uses a fine manual tool to make tiny strokes in the top layers of the skin and deposit pigment in a hair-like pattern. Because it breaks the skin, it is a tattooing procedure, and it needs the same standards as one: sterile single-use equipment, a clean environment and a proper consultation first.
This is why it differs from brow tinting or lamination, which stay on the surface of the skin.
Is microblading regulated in the UK?
Rules in England are set locally, not nationally. Councils license or register businesses that insert semi-permanent colour into the skin, and requirements vary by area. London boroughs use their own London-specific legislation to do this.
In practice, you should look for a studio that:
is licensed or registered with its local council, and can show you its certificate
employs an artist with formal training and recognised accreditation, such as PhiBrows
takes a full medical history before treatment
uses sterile, single-use equipment as standard
Brow Master London is a licensed studio in Notting Hill. Anna is PhiBrows-accredited with over 10 years’ experience and 5,000+ clients.
What Are the Risks of Microblading?
Risk | What it is | How it’s reduced |
Infection | Possible whenever the skin is broken. Warning signs are redness, warmth, swelling or discharge that gets worse after day 3. | Sterile single-use equipment and following aftercare. See your artist and your GP if you’re concerned. |
Allergic reaction | Rare, but pigment can trigger one. | A patch test for new clients. A negative result can’t rule out a reaction in the future. |
Uneven healing | Pigment can hold unevenly in places. | A complimentary touch-up within 4 weeks if required, where the artist fills gaps and refines the shape. |
Colour change | Pigment placed too deeply can drift towards blue, grey or red over time. | Artist skill and quality pigments. |
Scarring | Rare. Most likely with heavy-handed technique or a tendency to keloid scarring. | A thorough consultation and an experienced artist. |
Another risk is simply disappointing results. Mistakes can be hard to correct, which is why the choice of artist matters more than the choice of technique.
Who shouldn’t have microblading?
Microblading isn’t right for everyone. We take a full medical history at every consultation and will tell you honestly if it isn’t suitable. We may advise against it, or suggest an alternative, if you:
are pregnant or breastfeeding
have a history of keloid scarring
have an active skin condition in the brow area, such as eczema, psoriasis or rosacea
have diabetes, a blood disorder or take blood-thinning medication, as these can affect healing and are assessed individually
are undergoing cancer treatment
have very thin or compromised skin, or heavy older brow tattooing that hasn’t faded
have sunburned or recently tanned skin in the treatment area
Please also tell us about any medication you take, including acne treatments, so we can advise on timing. This list isn’t exhaustive, and a consultation is the only way to be sure.
Is Nano Blading Safer Than Microblading?
Not inherently, but they can suit some skin better. Nano hairstrokes use a digital machine with an ultra-fine needle instead of a manual blade. The machine tends to cause less mechanical trauma and deposits pigment more consistently, which can mean more predictable healing on oily, mature or sensitive skin.

How to choose a safe microblading studio in London
The safety of microblading depends more on the artist and studio than on the technique itself. Here's what to check before booking anywhere:
Ask to see the licence. Studios must display their council registration.
Check the artist’s credentials. Look for recognised accreditation, ongoing training and a track record such as competition results.
Look at healed results. Fresh brows always look sharp. Healed photos show the real outcome.
Expect a proper consultation. Skin type, medical history and previous brow work should all be discussed.
Watch hygiene practices. Blades and needle cartridges should be sterile, single-use and opened in front of you.
Be wary of very low prices. Correcting poor work often costs more than doing it well the first time.

Frequently Asked Questions
Is microblading safe? Yes, when performed by a trained artist in a licensed studio on a suitable client. Risks such as infection or allergic reaction are uncommon and mostly preventable.
Does microblading damage your skin? Done at the right depth by an experienced artist, it doesn’t cause lasting damage. Overly aggressive technique, or treating the same area too often, can cause problems.
Can microblading cause scarring? It’s rare, but possible with heavy-handed technique or in people prone to keloid scarring. A good consultation helps identify that risk beforehand.
Is microblading safe during pregnancy? We don’t perform microblading on clients who are pregnant or breastfeeding.
Can I have microblading with sensitive skin? Often yes, but it needs a thorough consultation and a patch test. Nano hairstrokes may be gentler for very sensitive skin.
How do I know if a studio is hygienic? Look for a visible council licence, sterile single-use equipment opened in front of you, a clean setting and an artist who happily explains their protocols.
