Mylash offer clinically proven lash growth treatments under consultation. These are not typical cosmetic eyelash serums. They contain active ingredients such as bimatoprost 0.03%, a medically active ingredient that was first developed for glaucoma and later approved for eyelash growth.
The key to getting the best result is not using more product. It is using the right amount, in the right place, consistently over time.
This guide explains how treatments like bimatoprost are normally applied, why once-daily use is standard, what mistakes to avoid, and how MyLash provides clinically proven treatment through a UK doctor led service.

What Is BIMATOPROST?
Bimatoprost ophthalmic solution 0.03% is a well known and widely studied lash growth treatment. It is approved by the US Food and Drug Administration for eyelash hypotrichosis, which means inadequate or insufficient eyelashes. The FDA label states that the solution increases eyelash growth, including length, thickness and darkness.
In the UK the solution can only be prescribed under medical supervision. Mylash have offered lash growth consultations since 2007; bimatoprost is just one of the treatments we can offer. We are focused on safe, doctor-led eyelash and eyebrow growth.
How Often Should A TREATMENT Be Applied?
To be effective, it’s likely any lash treatment will need to be applied once daily. We usually recommend applying in the evening, to the skin of the eyelid margin at the base of the eyelashes. Treatments like bimatoprost are not intended to be applied directly into the eye or to the lower lash line.
This is important because many people assume that using more often will improve results. In reality, bimatoprost does not work like a moisturiser. It acts on the hair follicle growth cycle. Once the follicle has been exposed, applying extra product does not necessarily produce better growth, but it may increase the chance of irritation.
In practice, we recommend applying it to clean skin after you have removed any makeup. This allows for maximum absorption as any makeup or moisturisers can act as a barrier, preventing it from soaking into the hair root.
Bimatoprost is water based so it dries quickly. If you apply it then brush your teeth, you will find that it has completely absorbed. Afterwards you can then apply any night creams without interfering with its action.
Why Once Daily Is Enough
Bimatoprost works by prolonging the anagen phase which is the active growth phase of the eyelash cycle. Over time this allows lashes to grow longer, thicker and darker.
The effect is gradual. It depends on the normal biology of the follicle rather than an instant surface effect on the hair shaft. This is why consistency matters more than quantity.
Most users should think of treatment as a daily routine, like brushing teeth or applying a night cream. One careful application each evening is better than irregular, excessive use. It truly is a case of “less is more”.
Step by Step Application
Time needed: 2 minutes
- Apply before bed
For best results, application should be regular, precise and hygienic. We recommend applying last thing at night before bed.
- Cleanse
First, remove makeup and contact lenses. The eyelid skin should be clean and dry.
- Apply precisely
Apply a small amount of the solution to a precision applicator. Then draw the applicator carefully along the upper lash line, where eyeliner would normally be applied.
- Repeat
Repeat for the other eye.
- Lower lash line?
Blinking naturally distributes a tiny amount of product to the lower lash area and often this is enough. However, some people apply to the lower lashes if they feel that the bottom lash line is not growing as well. A small amount of fluid is required so make sure not to overload the tissue.
- Eyebrow application
There is usually a small amount left on the applicator that can be applied to any area of the eyebrow that you may wish to thicken.
- Remove excess
After application, blot away any excess fluid from surrounding skin. Focus on transferring as little liquid as possible to the applicator next time, so no liquid is wasted.
Common Application Mistakes
The most common mistake is using too much. The lash line only needs a very small amount of solution. If liquid is running onto the eyelid skin or into the eye, too much has been applied.
Stopping and starting. The best results come with consistent application. The first couple of weeks are the most difficult, but when you start to see the results you will be hooked!
Finally, some people stop too early. Lashes grow slowly, so early results can be subtle. Full results usually take several months.
Should I Use a treatment Once or Twice a Day?
You only need to apply once a day.
Twice daily use is not recommended. It does not give double the result but it may cause irritation. That can mean more redness, dryness or unwanted hair growth around the treated area.
With bimatoprost, more is not better. Better is consistent, accurate and hygienic.
Morning or Evening: Which Is Best?
Evening application is usually best. Applying at night has practical advantages. Makeup has usually been removed, the eyelid margin is clean, and there is less chance of the product being disturbed by mascara, eyeliner or cleansing. It also means that you have removed your contact lenses.
Apply the treatment first to clean skin and allow it to dry before applying anything else. It is water based and quick drying, and it is not known to interfere with any other eye creams or moisturisers.
What Happens If I Miss a treatment?
If you miss an evening application, do not double the next dose or apply extra. Simply restart the following evening using the normal amount.
Occasional missed doses are unlikely to ruin progress, but frequent inconsistency will slow results. The best results come from steady, once daily use.
What Happens If I Stop Using It?
If you stop using bimatoprost the treated lashes gradually return to their natural baseline. This usually happens over several months as the normal eyelash growth cycle resumes.
Some believe that the follicle is permanently enlarged when using the treatment, leaving a larger hair, but there is no independent evidence proving this.
There is no rebound effect or shedding. The follicles are simply no longer being encouraged to remain in the growth phase for longer than usual, so their original size returns.
Who Should Be Careful Before Using Lash growth treatments?
Some of the treatments we offer are prescription only and are not suitable for everyone.
You should always disclose if you are pregnant, breastfeeding, have an eye condition, have had recent eyelid surgery, use glaucoma medication, or have previously reacted to any eye drops.
Bimatoprost was first used in ophthalmology for lowering intraocular pressure as a glaucoma treatment, and UK product information for bimatoprost eye drops includes cautions around eye irritation and contact lenses.
This is why MyLash uses a medical questionnaire reviewed by UK doctors before any treatment is approved. If you have a complex medical history then we often arrange a short phone call to discuss the treatment and ask questions to make sure that it is right for you.
We are almost always able to offer alternative treatments, if a specific treatment is not suited.

The Key Takeaway
For best results with, the correct approach is simple:
Use a small amount, once daily, on the upper lash line, with a clean disposable applicator, and keep going consistently for at least 16 weeks.
The result comes from biology, not excess. Accurate application and medical supervision are what make treatment safer, more effective and more predictable.

Frequently asked questions
Treatments are normally applied once daily in the evening to the lash line.
No. From our experience, twice daily use will not improve results and may increase the risk of irritation for no benefit. Using the smallest amount possible once a day will stimulate growth. Less is more.
Most people notice early changes within 3 to 4 weeks, but the full results take 16 weeks for all the eyelashes to complete a full growth cycle.
Do not apply extra. Simply restart your normal once daily application the following evening.
Yes. Bimatoprost is a prescription-only medicine in the UK and should be supplied through a doctor led service. Mylash are the experts and the longest established service; we offer an online consultation after which we will suggest an appropriate treatment or alternative product.
We recommend applying at night before bed. Remove all makeup and apply to bare skin. It dries quickly and you will be able to apply any night creams or moisturisers after 2 minutes or so.
