The skin is the largest organ and its hydration is essential to maintain its good condition .
The skin is made up of different layers:
Epidermis: the outer layer. In it we find the cells responsible for the sense of touch, immunity, others such as melanocytes, responsible for the production of melanin and also keratinocytes that produce keratin.
Dermis: The central layer. In it we find the blood vessels and also the sensory receptors that allow us to react to temperature, pain, pressure.
Hypodermis : the deepest layer. It protects muscle tissue, it stores blood and we also find adipocytes, fat cells that protect us from hot-cold.
The skin has its own biota and contains millions of microorganisms.
The skin barrier can suffer injuries, irritations caused by different factors such as cold, heat, sweat, solar radiation, radiotherapy, fabrics, insects, cosmetics (some ingredients such as alcohol, detergent perfumes).
Good hydration is essential to have skin well-being.
Skin hydration refers to the amount of water in it. When this water is lost from the epidermis, the outermost layer of the skin feels tight and rough and can even flake.
HOW CAN WE HYDRATE THE SKIN?
Hydration must be daily to care for the skin barrier.
The emulsions of cosmetic products usually have two types of emulsions depending on the skin type.
Ingredients can be categorized based on their mechanism of action as humectants, occlusives, and emollients.
Humectants their activity is to sequester water
Occlusives Maintain the water content of the skin layers.
Emollients Soften, soften and replace the skin's natural lipids.
Skin layer will need one type of emulsion and some or all of the ingredients.
It is important to know the state of the skin and the skin type in order to choose the right moisturizer and thus achieve the desired effect.
Formulation is creation, science and consciousness.
