Tendency to keloid scarring: 

Scarring is a normal process that happens in our body as a result of a wound and subsequent regeneration of the cells involved, in this case the skin cells. When there is a problem in this healing process, a hypertrophic scar (thicker than normal) or a keloid scar (thicker, more raised, and that surpasses the edges of the wound) can occur. When a person is prone to this type of scarring, it is not recommended to perform permanent lip makeup with any technique, while eyebrows and eyelids are recommended only with manual techniques and with specific authorization by the client where there is evidence of that it is his or her decision to carry out this procedure. It is important to note that there may be some abnormal scarring after permanent makeup in people who have not had any previous scar and who did not know they had a tendency to it.

Diabetes: 

People who suffer this condition have had seizures (involuntary movements). An epilepsy attack can be triggered by the stress that this procedure generates, so this is a contraindication. 

HIV and AIDS: 

This is a question that I always ask to my students: Would you do a procedure to a person who is HIV positive? some say yes, others say no . Those who say no are more afraid of contagion. My opinion is that you can perform this procedure using all the necessary measures to avoid cross contamination and treat each of your clients like if they were HIV positive, this is the only way that you never get contaged. But ,the most important thing is the well-being of your client. An HIV positive client under treatment usually has adequate levels of defense and the chances of infection are lower than in a client who has developed what is called AIDS where the patient is already immunologically compromised and has a higher probability of infection, in the latter case, the procedure is contraindicated. 

Hepatitis B or C:

These conditions are not contraindications, you should only take them into account as a precaution and to remind you that you should treat all your clients as if they were positive. Remember that these diseases are transmitted via blood and that you may get infected if you improperly manipulate the elements containing your client’s blood and you get to prick with the needle that you are working on. Fever blisters on the lips (cold sores). People who have suffered from this condition will always be prone to developing it after the procedure of permanent make-up on the lips. To prevent this from happening, it is recommended that the client request a prescription of a Zovirax-type antiviral agent from his or her family doctor. The client must start the medication the day before the procedure and continue it for as long as the doctor recommends. 

Active disease:

This is a procedure that must be performed in a completely healthy person in order to avoid any type of complication, whether related to the generation of an infection after the procedure if the person has weak defenses or because the color pickup is modified due to increased immunological reaction. Even if your client presents a simple cold, you must abstain from doing permanent makeup.
