No – not with full PlasmaPen treatment anyway (for rejuvenation only skin treatment – where the skin is not fully broken and the fibroblasts are not targeted – we can actually treat any skin type). For full PlasmaPen treatment, we only treat skin types 1 to 3 on the Fitzpatrick scale. Your technician will be able to determine precisely what skin type you are and will likely use one of our professional Skin Type Sensors. Treating anyone with darker skin than this with full treatment is putting clients at risk of pigmentation. The reason for this is that people with darker skins have melanocytes capable of making large amounts of melanin. When black skin is injured, for example, the melanocytes will usually either hyperpigment or hypopigment. Dark skinned people have a greater risk of forming keloid and hypertrophic scars too. As will be discussed in your consultation, certain skin types heal at different rates. For example, oily-skinned clients may take longer to heal. Our technicians give a great deal of consideration to clients who are contraindicated and/or who may have sensitivities. This will be discussed with you prior to any treatment and you should be completely honest and transparent in your responses. Clients with compromised immune systems may also take longer to heal and may not always achieve the results they expect due to their lymphatic system not working properly. Without a fully functioning lymphatic system, the cells responsible for the 4 phases of our procedures healing process (coagulation, inflammation, cell regeneration and tissue maturation) cannot always fully do their job properly and the rejuvenation, lifting and tightening of the skin may thus not then give the same level of results that are usually common with our PlasmaPen treatment.
