Cosmetic ingredient: It is prepared to be applied to different external parts of the human body such as the epidermis, nails, hairs, hair, lips and external genitalia, teeth and oral mucosa, with the sole or main purpose of cleaning these parts, giving scent, changing their appearance and/or correcting body odors and/or Any preparation or substance whose purpose is to preserve or keep in good condition.

So how well do we know these chemicals to which we expose our bodies? Let's learn together.

Cosmetics has become one of the fastest growing areas of the personal care industry, and many individuals today devote a significant amount of time and money to selecting and applying cosmetic products with the appropriate formulation; The cosmetics industry continues to grow in this way [1].

The use of biotechnology to meet the needs of this growing industry is becoming increasingly important for cosmetology. Biotechnological developments in recent years have helped develop more effective and efficient methods for the production of a number of raw materials that play an important role in cosmetic formulations [1]. In our new article series, we will focus on the introduction/investigation of formulations containing active substances with various functions, which are produced by biotechnological methods and suitable for cosmetic use, together with their design and intended use.

Cosmetics and Cosmeceutical

Cosmetology, derived from the word kosmein, which means to decorate, is a science that systematically examines the human body related to cosmetic preparations and these preparations.

Mankind has always wanted to look beautiful and be attractive. For this reason, developments in the field of cosmetology have been continuing increasingly from the first ages to the present [2]. Researchers working on cosmetology have searched for new product ideas that can be produced by methods such as biotechnology and plant cell culture technology to meet the needs of the rapidly growing cosmetics industry and the consumer. Thanks to this search, the role of biotechnology in cosmetic formulations has gradually increased.

The cosmetics industry has fields of study including anti-aging, anti-hyperpigmentation, moisturizer, sunscreen products and perfumes, which include preparations with wide usage areas for skin, body and hair [1]. However, with the expansion and diversification of the cosmetics industry, the expected effect from the products has deepened. In order to achieve this effect, cosmetic substances have been started to be prepared in carrier systems such as microcapsules, liposomes and nanoparticles by making use of biotechnology.

In addition, some substances that accelerate the regeneration of cells, nourish the skin, increase blood circulation, and prevent the harmful effects of the sun are added to these cosmetics and their positive effects on the structure and functions of the skin are utilized. In order for these substances to have the desired effect on the skin, they are absorbed into the living epidermis or dermis layers of the skin (Figure 1). Thus, they began to show their effects in the deeper layers of the skin. Therefore, these modern cosmetics of today do not comply with the definition of classical cosmetics and are considered as a new group between medicine and cosmetics. cosmeceuticals or active cosmetics constitute [2].

Cosmetics are agents used to enhance the beauty of the skin or improve the appearance of the skin. Safety and efficacy of these products may not need to be presented prior to sale and marketing. In contrast, drugs aim at the treatment or prevention of diseases. For this reason, ensuring the safety and effectiveness of these products is essential for the sales and marketing of these products to progress [1].

Cosmeceutical, on the other hand, is derived from the words "cosmetic and pharmaceutical". It aims to describe skin care products that fall between these two categories. Cosmeceuticals are cosmetic products containing drug-like active substances that protect or improve the appearance of the human body, have anti-aging and moisturizing properties [1].

Cosmeceuticals form a bridge between cosmetics and drugs; It helps to change the structure and functions of the skin and skin-related formations such as hair, nails and bristles to a certain extent and change it positively.

Thanks to these effects, cosmeceuticals have become the fastest growing area of ​​the cosmetics industry. Among the most used cosmeceutical products, there are anti-wrinkle products, anti-aging products, skin whiteners, antioxidants and cell regenerators [1].

cosmeceuticals; They contain active ingredients such as vitamins, phytochemicals, polysaccharides, enzymes, antioxidants and essential oils. The profound effect and ability of cosmeceuticals to heal the skin depends on the formulation of the active ingredient in appropriate amounts in a carrier that can preserve its integrity and deliver its biologically active form to the target area.

Biotechnological advances in recent years have helped develop more effective and efficient methods for the production of a number of raw materials that play an important role in comeceutical formulations. While recombinant proteins, growth factors, and cytokines may seem like components of a drug development strategy, each is an investment by biotech companies to fulfill society's desire to look young and beautiful.
represents the approach [1].

In our next article, we will begin to get to know these approaches more closely. Until then, stay healthy and beautiful.
