Who should not have laser IPL hair removal?

This really depends upon the type of machine used by a clinic and your skin and hair colour.
There is a wide variety of equipment promoted by around thirty manufacturers and distributors in China.
Some of the newer machines available claim that they can treat all skin types and hair colour, however other pieces of equipment may be more limited. As a result, some clinics may not be able to treat you for the following reasons:
if you have ginger hair which may respond poorly to the treatment. Blonde or white hairs sometimes hardly respond at all;
Mediterranean, Middle and Far Eastern skin types may need to be treated with care;
darker skin types than the groups listed above. They may not suitable for the stronger lasers because the skin pigment absorbs too much energy causing unwanted damage. Similarly, patients who have recent sun tans should wait until their tan fades.

General reasons of unsuitability not related to skin and hair type include:
1.any history of sensitivity to light based treatments;
2.an active infection at the site to be treated;
3.patients who have used the drug isotretinoin in the last year.
