Skin's Cosmetic Properties

Skin’s Roles

The skin is the largest organ of the human body and is often exposed to the outer environment.

It acts as the main barrier that protects us from various external factors preventing our organism from water loss and blocking the noxious impact of dust, pollution, wind, sun, and infectious microorganisms.

We rarely realize, but the skin has also a very important social role. The appearance of the skin influences our self-esteem, self-confidence, and even our social behavior.

To get the social advantages coming from younger and better-looking skin, we use a variety of cosmetic products, often combined in complex skin care procedures. They are all about one thing – to feel more comfortable and to improve our confidence and social expression by taking care of the good appearance of our skin.

Skin’s Structure

The skin consists of two principal layers:

  1. The derma, where the blood vessels, nerves, and sweat glands are situated. It plays an important part in the skin’s hydration levels and elasticity.
  2. The epidermis is the visual layer of the skin and has a major barrier and cosmetic role.

The basic function of skin care products is to improve the structure and appearance of the epidermis.

The epidermis combines two main layers that have cosmetic importance:

stratum granuslosum (SG) that consists of live cells and contains about 70% water

stratum corneum (SC) that consists of dead cells and a lipid matrix, plays a major barrier role and contains 15-30% water.

It is by the state of the epidermis that we reveal the cosmetic condition of our skin: whether it is dehydrated, oily, dry, sensitive or other.

Skin Care Regulations

Skincare products are targeting the outer skin layer – the epidermis known as the cosmetic layer. According to the EU regulation they are not supposed to penetrate the lower skin layers and alter skin cells’ normal metabolism. Otherwise, they should be considered pharmaceutical products.

The epidermis is the visual layer of the skin and its appearance depends on the skincare products and routines. The way a product is affecting the skin determines if it is cosmetic or pharmaceutical. Also, it shows, if a procedure is cosmetic, performed in a cosmetic studio or medical, made in a dermatological clinic.

Anyway, by default, skincare products are used to improve the skin’s visual appearance.

Skin Care’s Role

The epidermis thickness is variable and its capacity to obtain and preserve water differs a lot as does its ability to produce skin lipids (sebum).

It is this variation that creates the different skin types and is responsible for many skin conditions that we determine as cosmetic conditions.

One of the most important roles of cosmetic products is to keep the epidermis clean and well hydrated.

Using appropriate cleansing and moisturizing skincare products, according to the skin type and the cosmetic conditions, give optimal results in skin’s health and appearance.

Skin Types and Conditions

Skin Types

To give your skin the best possible care, it is important to understand the difference between skin types and skin conditions.
Your skin type is predetermined by your genes – it is the skin you are born with, and the one that is with you for life.

There are three main skin types: oily, normal and dry.

Some people may have more than one skin type, which is often referred to as combination skin.

Skin Conditions

When we talk about skin conditions, we mean those regarded as cosmetic skin conditions and not clinical (like dermatitis for example).
Skin conditions are determined by the lifestyle and the external factors such as dry or humid weather, hot or cold wing, sun damage, and so on.

Only five principal skin conditions are considered cosmetic: aging skin, dehydrated skin, sensitive skin, skin pigmentation, blemished skin (clogged pores).
