Dermarollers with 0.2mm and 0.3mm microneedle lengths have been designed for personal, cosmetic use at home, as part of the skin care regimen. Their main purpose is to enhance the penetration of active ingredients from serums and creams into the deeper layers of the skin, which leads to an incredible increase in their efficacy. The minuscule skin “tunnels” created by the roller support the absorption of the active ingredients formulae dramatically, which helps to improve and maintain the healthy appearance of the skin. Dermaroller models are also recommended for use in between clinical or medical Skin Needling treatments, usually set 2-3 months apart, and after the closure of the clinical/medical treatment programmes, to sustain skin regeneration results. Downtime Due to minimal level of needle insertion, the Personal Dermaroller models are safe to use at home and are regarded as practically pain-free by the majority of users. The Personal Dermaroller models are associated with very little downtime when used vigorously and with none if used as per instructions.
