treatment is defined as a cosmetic treatment. The term
‘cosmetic’ generally describes personal hygiene and beauty care. Thereby, it is focused on the preservation and the improvement of wellness and beauty of the human body. In this context, it should be mentioned that cosmetic products in accordance to the Cosmetic Regulation 1223/2009/EC can be applied on itchy skin for cosmetic purposes, for example in atopic dermatitis or psoriasis. Cosmetic creams with moisturizing and soothing ingredients can help to restore the barrier function of the skin. In this way one can prevent penetration of harmful

germs and bacteria and prevent inflammation. The microneedling treatment of healthy skin for the purpose of accelerated skin renewal (anti-aging) is generally considered a cosmetic treatment. Manufacturers determine the intended use of their
devices. Therefore, it is standard practice in Europe that technically identical devices with a medical intended use to cure diseases or relieve pain according to the Medical Device Directive (MDD) (93/42/EEC) and devices without any medical intended use according to the machinery directive 2006/42/EC can be simultaneously placed on the market. For both types of equipment, conformity tests shall be carried out, which shall be verified to ensure patient safety and customer safety, respectively.
Types of microneedling Regarding the degree of invasiveness, referring to the extent of the integrity violation of the skin (depth and intensity of needle penetration), three different types of microneedling can be distinguished: Non-invasive microneedling treatment Minimally-invasive microneedling treatment Invasive microneedling treatment.3
Mode of action of non-invasive microneedling The non-invasive microneedling treatment is primarily understood to be an innovative application method for applying compounds onto the skin. These compounds can be cosmetic products, such as anti-aging lotions, as well as medical or medicinal products, including pain- relief ointments. The non-invasive microneedling treatment of the epidermal barrier improves the absorbability of the skin for the topically applied compounds. Simplified, one could say, the compound is effectively massaged into the skin by the non-invasive
