Microagulhamento e reposição oral de colágeno como estratégias de rejuvenescimento cutâneo

Abstract

Background: Skin aging is caused by a combination of intrinsic and extrinsic factors. The main clinical manifestations of photoaging are: the presence of wrinkles, dilated pores, the xerosis, the roughness, the changes in pigmentation and sagging. The existing therapeutic options for photoaging treatment vary from topical agents, chemical peels, laser, dermabrasion and microneedling. Microneedling consists of a physical stimulation performed through micropunctures in the skin, capable of inducing inflammatory response, and that results in the production of new collagen, organized in a structured way, improving the appearance of the skin. Oral supplementation of hydrolyzed collagen to improve skin conditions has been studied. Aims: To evaluate the microneedling technique associated with the oral supplementation of hydrolyzed collagen as skin rejuvenation strategies. Methods: Tirty volunteers were divided into 2 groups: one (received two microneedling sessions associated with oral replacement of collagen for 6 months) and group 2 (received two microneedling sessions). Were used as evaluation methods: application of a self-perception questionnaire at 30 and 180 days and multispectral analysis of at 0, 30, 60 and 180 days. Results: Self-perception referred to as "significant improvement" was attributed by the majority of the participants, in greater number in group 1. Group 1 showed superior improvement of wrinkles compared to group 2 (p = 0.032) and also of texture (p= 0.446). There was no improvement of the other parameters (spots, pores, porphyrins and red areas).. Conclusion: The microneedling associated with oral collagen replacement can be considered an effective strategy in the treatment of cutaneous aging.
