Biopolymers are compounds prepared by using various living organisms, including plants. These are composed of repeated units of the same or similar structure (monomers) linked together. Rubber, starch, cellulose, proteins and DNA, RNA, chitin, and peptides are some of the examples of natural biopolymers. Biopolymers are a diverse and remarkably versatile class of materials that are either produced by biological systems or synthesize from biological sources. Biopolymers are used in pharmaceutical industry and also in food industry.Naturally derived polymers are also used for conditioning benefits in hair and skin care. Biopolymers have various applications in medicine, food, packaging, and petroleum industries. This review article is focused on various aspects of biopolymers with a special emphasis on role of biopolymers in green nanotechnology and agriculture.

Microscopic prokaryotic and eukaryotic algae (microalgae), which can be effectively grown in mass cultures, are gaining increasing interest in cosmetics. Up to now, the main attention was on aquatic algae, while species from aeroterrestrial and extreme environments remained underestimated. In these habitats, algae accumulate high amounts of some chemical substances or develop specific compounds, which cause them to thrive in inimical conditions. Among such biologically active molecules is a large family of lipids, which are significant constituents in living organisms and valuable ingredients in cosmetic formulations. Therefore, natural sources of lipids are increasingly in demand in the modern cosmetic industry and its innovative technologies. Among novelties in skin care products is the use of lipid nanoparticles as carriers of dermatologically active ingredients, which enhance their penetration and release in the skin strata. This review is an attempt to comprehensively cover the available literature on the high-value lipids from microalgae, which inhabit aeroterrestrial and extreme habitats (AEM). Data on different compounds of 87 species, subspecies and varieties from 53 genera (represented by more than 141 strains) from five phyla are provided and, despite some gaps in the current knowledge, demonstrate the promising potential of AEM as sources of valuable lipids for novel skin care products.

The article provides information about the features of the structure, development and differentiated approach to the appointment of dexapanthenol preparations used for the prevention and complex treatment of skin diseases in children of wounded age. Regular use of leave-on cosmetic products including body creams and lotions is very high among children aged 0–4 years. However, in most cases, recommendations for the use of topical baby skin care medicinal products and/or cosmetic products are based not on scientific evidence, but on common sense, expert opinions, advertising, personal preferences of parents, pharmacists, dermatologists and/or pediatricians. For example, adsorbing properties of baby powders are insufficient, and after absorbing moisture, they actually turn to “urine compresses” that aggravate the epidermis injury. After swelling, the starch-containing powders represent an excellent growth media for pathogenic and opportunistic microflora. It is noted that only proper skin care for young children allows you to preserve its integrity and functional state. Special attention is paid to the preparations of the Bepanten® series in the form of cream and ointment, which meet all the criteria for topical products, and can be used for the prevention and treatment of skin diseases in young children, effectively protecting the skin from irritants, promoting its healing and recovery, having an anti-inflammatory effect, increasing its elasticity, elasticity and are recommended for use as a means of basic care. Their effectiveness has been repeatedly confirmed in the numerous domestic and foreign randomized controlled studies in new-born populations at different gestational ages, which provided the scientific justification for their common use in the ‘real-life’ practice of pediatricians, dermatologists and allergists.

Learning outcomes are a learning carried out by someone after  going through the process of learning activities, which uses an assessment tool prepared by the teacher, such as an evaluation test that includes cognitive, affective and psychomotor aspects. This study aims to determine the relationship between student interest in the use of Google Classroom with learning outcomes of facial skin care with technology. This research is a quantitative research with a survey method with a sample of 65 students of the Cosmetology Education study program batch 2020. The data for the X variable (student interest in using Google Classroom) was obtained by distributing questionnaires with a Likert scale. Meanwhile, the Y variable data (Learning Results of Facial Skin Care with Technology) was obtained from Form 06. The results of the analysis with product moment correlation showed that there was no positive and significant relationship between students' interest in learning outcomes of facial skin care with technology. Based on the calculations obtained a significance value of 0.274 which means it is greater than 0.05. So it can be concluded that Ho which reads: "Students' Interest in Using Google Classroom does not have a positive effect on Learning Outcomes of Facial Skin Care with Technology" is accepted. On the other hand, "Students' Interest in Using Google Classroom has a positive effect on Learning Outcomes of Facial Skin Care with Technology" is rejected. The effective contribution was obtained by 1.9% and the remaining 98.1% was not examined in this study.
