Terms & Conditions

Our service

Eyelash Logic provides a service to those wishing to enhance their eyelashes. The treatment is prescription-only and is subject to approval and prescription by a medical doctor. The order process incorporates a medical questionnaire. If the doctor decides that it is not in your best interest to receive treatment then you will not be charged.


There are individuals for whom we will not prescribe treatment due to the following contraindications:

Active eye disease

Any active eye disease, including intraocular inflammation (uveitis), glaucoma and macular oedema. Anyone with previous serious eye disease is likely to not receive treatment.

Pregnancy or Breastfeeding

While there are no adequate studies for eyelash enhancing products in pregnant or nursing woman, it should not be administered during pregnancy due to unknown risks to the fetus. We would not offer treatment to breastfeeding mothers.


People with known hypersensitivity or allergy to benzalkonium chloride, sodium phosphate, citric acid, sodium chloride, purified water, sodium hydroxide or hydrochloric acid.

Contact Lenses

Contact lenses should be removed prior to application of solution and may only be reinserted 15 minutes after the treatment.

Risks and Side Effects

The possible side effects of this treatment include but are not limited to:


There is a risk of itching, vascular congestion in the eye, irritation, dry eyes, redness or allergic reaction. Redness and itching of the eye are the most common side effect, and have been demonstrated in less than 4% of patients.


Infection can occur whenever any product is used near the eye. In most cases this is easily treatable, but in theory an infection could cause permanent scarring. This has never been reported for this product but we cannot rule this out in the unlikely case of an infection occurring.


Increased iris pigmentation has occurred when the formulation was instilled directly onto the eye, although this is rare. You should be advised that the potential for increased brown iris pigmentation is likely to be permanent should this side effect occur. Iris color changes may not be noticeable for several years. 

Skin pigmentation may occur at the site of application. This is not thought to be permanent and is likely to subside with discontinuation of treatment. 


This product should be used exactly as directed to reduce the risk of complications and side effects. The bottle must be kept intact during use and the bottle tip should never be allowed to contact any surface. An applicator is used to apply a solution to the base of the upper eyelash only. Applicators should only be used once on each eye and then discarded. You should not use this treatment more than once per day. Additional application will not increase results and may increase the risk of possible complication and side effects. We do not recommend treatment on any other areas other than the eyelashes. Clients should maintain a good relationship with their GP and to relay any information regarding any treatments that they undertake to them.


Clinical trials have demonstrated an average outcome of 25% longer, 106% thicker and 18% darker eyelashes over a 16-week period. As with any medical or cosmetic treatment, there is a possibility of therapeutic failure and so we are unable to guarantee the results. Upon discontinuation, eyelash growth will return to its pre-use level.


Our treatment plans range from £129 for 3 months to £429 for 12 months at the standard rate. A parallel but reduced pricing structure may apply for those wishing to enroll in a treatment subscription, which will be subject to regular online consultation.

Alternative Treatments

Alternatives to treatment include no treatment, the use of eyelash extensions or fake eyelashes and tinting or colouring of the eyelashes.


We will normally process your order within 48 hours. Delivery may take 5 working days from dispatch, although most orders are delivered within 3 working days.


If for any reason you are unsatisfied with the product you must notify Eyelash Logic within 30 days of receipt. We will then provide instructions for returning the product and, once returned, we will issue a full refund. We cannot guarantee the efficacy of any treatment, and so returns will not be permitted outside of this 30-day period.
