What is NOT considered a contraindication for certain treatments?

Chloasma, often referred to as melasma, is a skin condition characterized by brown or gray-brown patches on the skin, primarily affecting the face. It is commonly associated with hormonal changes, such as those occurring during pregnancy, but is generally not considered a contraindication for many cosmetic treatments. In the context of esthetics, while it may require special consideration for certain procedures, it does not typically pose the same level of risk or complications as inflammatory skin conditions like eczema, dermatitis, or psoriasis, which can actively flare up and cause irritation or adverse reactions during treatments.

Each of the other conditions listed represents inflammatory skin disorders, which may lead to heightened sensitivity or reactions if treated with particular methods. They often require adaptations in treatment protocols or even a complete avoidance of certain services to ensure the client's skin is not further aggravated. Thus, chloasma stands out as a condition that does not inherently restrict the use of many esthetic procedures.
