The skin is the largest organ in the human body and performs several functions, such as regulating body temperature, protecting against external agents and absorbing nutrients. The skin is also an important indicator of health, as it reflects changes in the general state of the body.

Every day, our skin suffers from the aggressions of the environment and pollution, which causes premature aging. Fortunately, nature provides us with many ingredients that can be used to care for the skin and slow down the aging process.

One of the main characteristics of the skin is its ability to constantly renew itself. Approximately every 27 days, the skin completely renews itself. This cell renewal is responsible for the youthful and healthy appearance of the skin. Over the years, this ability to renew is reduced, which causes the appearance of fine lines, wrinkles and spots on the skin.

Maintaining young and healthy skin requires constant care, both internally and externally. Diet is an important factor in maintaining skin health and delaying the aging process. The consumption of fruits, vegetables, greens, whole grains and water are mainly essential to keep your skin hydrated and looking healthy. Unlike the cosmetic products we buy on the market, natural foods contain a wide variety of nutrients that directly benefit the health of the skin.

How does the skin renew itself?

Skin is our body's largest organ, and it constantly renews itself to stay healthy. Every 28 days, our skin completely renews itself. It's an incredible process that happens without us realizing it, but it's essential for our health.

During a human lifetime, your skin is renewed on average about 900 times! That's right, to stay healthy and beautiful, your skin goes through a lot of effort and goes through a lot of changes.

The skin renewal process is divided into three stages: the production of new cells, the elimination of old cells and the repair of damage.

The production of new cells begins in the deepest layers of the skin, where there is a tissue called the dermis. The dermis is made up of a network of collagen and elastin fibers, which give the skin its strength and elasticity. These fibers are produced by a special type of cell called a fibroblast.

Fibroblasts synthesize the collagen and elastin fibers that form the skin's support network. In addition, fibroblasts also produce other important substances for the skin, such as glycosaminoglycan (GAG), which is a connective tissue component that helps maintain skin hydration.

New dermal cells are produced from a layer of cells called keratinocytes. Keratinocytes are the cells responsible for forming the surface layer of the skin, called the epidermis.

The epidermis is a very thin layer that protects our body against attack by bacteria, viruses and other pathogens. Furthermore, the epidermis is also responsible for regulating body temperature and allowing perspiration to occur to keep our body cool.

Keratinocytes are produced in the lower part of the epidermis, in a layer called the stratum basale. These new epidermal cells gradually migrate to the surface of the skin, where they transform into more mature cells.

On the surface of the skin, epidermal cells are constantly exposed to the environment and suffer damage from the action of the sun, wind and other aggressive agents.

Therefore, it is important that there is a constant renewal of these cells so that the skin can remain healthy.

The elimination of old cells occurs in the superficial layer of the skin, called the stratum corneum. In this layer, the cells of the epidermis are surrounded by a substance called keratin, which is a fibrous protein.

Keratin is responsible for giving the cells of the epidermis their rigidity and impermeability. When epidermal cells are exposed to the environment, the keratin is damaged and deteriorates.

This causes the cells of the epidermis to lose their rigidity and impermeability, which makes them more vulnerable to damage from the environment.

Therefore, it is important that there is a constant renewal of these cells so that the skin can remain healthy.

Damage repair is an important process that takes place in the skin so that it can recover from damage caused by the environment. This process is done by a substance called collagen, which is produced by fibroblasts in the dermis.

Why is it important to take care of the skin?

The skin is the largest organ in our body, and it is constantly exposed to external aggressions, such as the sun, wind and pollution. Therefore, it is very important to take care of the skin to keep it healthy and beautiful.

The skin is renewed about 900 times during our lifetime, but from the age of 20 this renewal rate decreases. Therefore, it is important to carry out adequate treatment to keep the skin always healthy and beautiful with products such as moisturizers and serums.

What is the best product for my skin?

The skin is our body's largest organ, so it's important to take care of it to keep it healthy. One way to do this is to choose the right products for your skin type.

There are basically four skin types: normal, dry, oily and combination. Normal skin is balanced, with good hydration and elasticity. Dry skin has dehydration, loss of elasticity and may be flaky. Oily skin has excess sebum and tends to be more prone to acne. Mixed skin has characteristics of both dry and oily skin, usually in regions of the face such as the nose and chin.

To choose the best product for your skin, it is important to identify your skin type. After that, you can search for specific products to suit your needs.


Our skin is exposed to various factors throughout life, such as climate, pollution and UV rays. All this can affect how it renews itself. But according to studies, our skin renews itself about 900 times during our lives.

Taking care of your skin is essential with moisturizers, and especially UV protection with sunscreen.
