Abstract

External factors such as prolonged exposure to solar radiation and environmental pollution accelerate the aging process of the skin, and this process is a challenge for pharmacological science. To counteract the effects of skin photoaging, the cosmetic industry has introduced natural topical products that have proved to be effective in reducing signs of age. In this sense, a statistical analysis was conducted on the changes in the properties of firmness and elasticity of the skin caused by cosmetic formulas (lotion and cream) elaborated with essential oils of Aristeguietia glutinosa (matico) and Ocotea quixos (ishpingo) in which the concentration of the oils in two cosmetic products (lotion and cream) varied to be tested in vivo, through the measurement of elasticity and firmness in three times T1 (0 day), T2 (28 days) and T3 (56 days), and in two age groups according to the Glogau scale (30 to 40 and 41 to 50 years). The results showed positive changes in the values of elasticity and firmness of the skin in the presentation of the lotion whose concentration was 20% Aristeguietia glutinosa (matico) and 80% Ocotea quixos (ishpingo), with a minimum application time of 28 days.

Highlights

UVB radiation causes DNA damage, allowing UVA rays to penetrate into the dermis, significantly increasing the production of reactive oxygen species (ROS) that cause long-term skin damage [1].The theory of aging considers, on the one hand, the genetic condition of each organism and, on the other, a non-genetic process that includes ROS [2].Living tissues have a control mechanism to keep ROS in balance, and many antioxidants are used [3] when they are generated in vivo
The objective of the research is to conduct a statistical analysis of changes in skin elasticity and firmness caused by cosmetic formulas elaborated with essential oils of Aristeguietia glutinosa and Ocotea quixos
The cosmetic formulas used for this study were a cream that consisted of a homogeneous oil/water (O/W) emulsion resulting from the mixture of two immiscible phases

Summary

Introduction

UVB radiation causes DNA damage, allowing UVA rays to penetrate into the dermis, significantly increasing the production of reactive oxygen species (ROS) that cause long-term skin damage [1].The theory of aging considers, on the one hand, the genetic condition of each organism and, on the other, a non-genetic process that includes ROS [2].Living tissues have a control mechanism to keep ROS in balance, and many antioxidants are used [3] when they are generated in vivo. UVB radiation causes DNA damage, allowing UVA rays to penetrate into the dermis, significantly increasing the production of reactive oxygen species (ROS) that cause long-term skin damage [1]. Antioxidants are used in the dermatological field to minimize the appearance of wrinkles or the hyperpigmentation, as they improve their appearance in a natural way [4]. In this sense, the cosmetic industry is increasingly prone to the development of natural botanical ingredients and polypeptides that give skin improvement properties with a successful effectiveness [5]. Cosmetics with natural ingredients, such as essential oils, are a personal care alternative with a growing trend for the coming years [6]
