Good Morning!! 🙌 Hivers, As my beautiful mother says: "There is no Saturday without sunshine, no Sunday without love". On this most beautiful Sunday on the eve of Christmas🎊🌲🎅, I invite you to stop and immerse yourself in a few minutes of educational and technical reading to understand ourselves a little more and to be able to give more love; yes, of course love of the good kind, but for ourselves❤️.
1. Piel y generalidades
1. Skin and generalities
La piel del hombre actual no es, ni remotamente igual a la piel de los primates antropoides más antiguos, de hace 15 millones de años. Nuestros más antigüos ascendientes tenían la piel oscura y cubierta de tupidos pelos. El hábitat y las condiciones que tenían para conseguir a alimentos(Fenómeno que se produjo por la necesidad de cazar presas de rápidos movimientos), condicionó a que la densidad del pelo disminuyó, y el número de glándulas sudoríparas aumentó notablemente; y así, lograr un sistema de control rápido y eficiente de la temperatura corporal.
La piel es un verdadero vestido fisiológico con importante secreciones internas y externas. En el hombre adulto la piel tiene una extensión promedio de 1.85 m2 y un peso de 4.22 kg. Es el órgano más pesado del organismo. Cada individuo nace con un tipo de piel que lo acompañará toda la vida. Ella revela su tipo étnico: blanco, amarillo, negro, mestizo, afroamericanos, mulatos, etc. En los niños es muy hidratada y en el anciano seca y poco elástica.
The skin of today's man is not even remotely like the skin of the oldest anthropoid primates of 15 million years ago. Our most ancient ancestors had dark skin covered with dense hairs. The habitat and the conditions they had to obtain food (a phenomenon that was produced by the need to hunt fast moving prey), conditioned that the density of hair decreased, and the number of sweat glands increased significantly; and thus, to achieve a fast and efficient control system of body temperature.
The skin is a real physiological garment with important internal and external secretions. In the adult male, the skin has an average extension of 1.85 m2 and a weight of 4.22 kg. It is the heaviest organ of the organism. Each individual is born with a skin type that will accompany him all his life. It reveals its ethnic type: white, yellow, black, mestizo, African-American, mulatto, etc. In children it is very hydrated and in the elderly it is dry and not very elastic.
2. Biotipos Cutáneos
The classification of skin biotypes is made according to the secretion of the sebaceous and sweat glands. These secretions form in the skin the HYDROLIPID MANTLE which constitutes an emulsified layer that in equilibrium provides the skin with lubrication and regulated humidification.
Se clasifican en 4 tipos diferentes:
- Piel Eudermica o normal.
- Piel Grasa.
- Piel Alipica o seca.
- Piel Sensible.
They are classified into 4 different types:
- Eudermic or normal skin.
- Oily skin.
- Alipic or dry skin.
- Sensitive skin.
Eudermic or Normal Skin
CHARACTERISTICS:
- Perfect secretory balance sebaceous and sweat.
- Smooth surface, soft to the touch.
- Uniform color.
- Moderate shine.
- Little visible pores.
- Absence of unsightly aspects.
- Tolerates soaps well, does not flake and resists extreme temperatures.
- The hydration of this skin is perfect and is regulated by the biological activity of the basal layer.
Oily Skin
CHARACTERISTICS:
- Coarse textured skin.
- Dilated pilosebaceous follicles.
- Oily to the touch.
- Little tendency to form wrinkles.
- Resist action of external agents by the permanence of sebaceous secretion.
- Seborrhea is located in the scalp, facial center (T zone), central thoracic and interscapular zones.
- Sebaceous secretion may vary in greater or lesser intensity.
Alipic or Dry Skin
CHARACTERISTICS:
Thin, tight skin .
Reactive to external stimuli .
Imperceptible pores.
Not very flexible.
Dull color.
Fine desquamation.
Predisposition to form wrinkles.
Poor tolerance to soaps.
Sensitive Skin
CHARACTERISTICS:
- Reacts faster or more intensely than normal skin.
- Burning, itching, peeling and reddening reactions are frequent.
- Predominates in lighter skin tones.
3.Fototipos Cutáneos
3.Skin Phototype
The Fitzpatrick skin phototype scale provides information on skin sensitivity to ultraviolet light. Fitzpatrick proposed it in 1975 based on a personal interview exploring the history of sunburn and the ability to tan, looking for an estimated approximation of skin tolerance to UV light.
Fitzpatrick classification:
- Phototype I: The hair is red or orange, and the skin, very light or milky. They burn very easily.
- Phototype II: The hair is blond and the skin is light. It burns easily, and tans minimally.
- Phototype III: The hair is blond-brown and the skin is light-dark. It burns minimally and tans with difficulty.
- Phototype IV: Light-brown hair, tanned skin. Burns minimally and tans well.
- Phototype V: Dark skin, almost never burns and tans quickly.
- Phototype VI: Black skin. Never burns and tans deeply.
Como en el campo de la medicina clínica, será ideal diagnosticar personalmente las características propias de nuestra piel. Así poder seleccionar en base a esos conocimientos los productos y técnicas más adecuadas para nuestra salud.
