Skin Types


Hello bello, my fabulous reader! How are you? Enjoying this lovely Fri-yay? So, a few days ago, I borrowed a book called The World Of Skin Care by Dr John Gray. It's such an useful book, I mean there's a lot of information and it's pretty awesome! So, I thought I'd write blog post(s) about it, the first one (this one) is about human skin types, let's get started:

Normal Skin 

The Characteristics of 'normal' skin can be summarized as follows:
  • A clear appearance 
  • An even color 
  • Feels neither tight nor greasy 
  • Soft and supple to the touch 
  • A high degree of elasticity 
Normal skin may be said to have nothing obviously wrong with it, and no sensations of discomfort. It results from a balance of the normal skin functions (including new skin cells being formed and old ones being lost, together with well-controlled water loss, sebum secretion and sweating). This creates a balanced state of suppleness, elasticity, color and hue which is often characteristic of pre-adolescents.
Normal skin can quite quickly become 'abnormal', however. Failure to look after it, or abuse by sun, wind or cold, may lead to dry and damaged skin and ultimately the risk of premature development of lines and wrinkles. 

Dry Skin 

Dry skin: 
  • Feels tight and irritable 
  • Often looks flaky 
  • Often develops fine lines around the eyes 
  • Tightens after washing with soaps or detergents or prolonged exposure to low humidity. 
Dry skin is characterized most of all by this sensation of tightness, with the skin feeling rough and scaly and visible lines developing. At its worst it may look cracked. The problem lies in poor epidermal function and damage to the water/lipid barrier film, shown by an increase in the rate of transepidermal water loss (TEWL)
Patches of dry skin may arise from apparently normal skin, or sometimes even greasy skin, that has been temporarily dried out, whether by sunburn, or by exposure to extremes of climate (cold, heat, wind or dryness) or to chemicals such as detergents and solvents or to air conditioning. In young people the main problem of dry skin is a reduced production of sebum. 
Dryness is a significant problem associated with mature skin as hydration ability progressively decreases and the skin's mechanical properties deteriorate, with loss of suppleness and flexibility. 

Greasy (oily) skin 

Greasy skin (sometimes called seborrhoeic skin) generally appears at puberty although in a few people it starts much earlier, from the age of six upwards. It is rare after the age of 35. It involves only the upper part of the body, where greater numbers of sebaceous glands are found.
This type of skin is particularly common in adolescents and young adults. At this age there is in both sexes a dramatic increase in sebum production under the influence of the male sex hormones. The extra sebum gives the skin a shiny appearance, especially on the nose and forehead. The epidermis tends to thicken, due to increased keratin production, and the pores dilate. As a result the skin feels rough and irregular. 

Mixed skin 

Mixed skin (often called combination skin) is characterized on the face by thickened, shiny skin associated with patches of dry skin. 

Sensitive skin 

In addition to these recognized types of skin, many people believe that they have 'sensitive skin'. 
Doctors and scientists are not completely agreed about what 'sensitive skin' is, but it may generally be considered as skin which is easily irritated. It is more commonly associated with people with type I skin, and probably has a genetic element. 
Some people with this condition cannot tolerate contact with any cosmetic products, however well-formulated they may be. Sensitive skin can be associated with a medical condition called atopy, where people have an inherited predisposition to eczema, hay fever and asthma.
Truly sensitive or atopic skin may: 
  • Feel very tight after washing. 
  • Have a naturally high TEWL rate.
  • React to many external stimuli by becoming red and blotchy. 
  •  Be prone to developing dry flaky patches.

So, that's all for today! I hope that you guys enjoyed reading it and always remember, no matter what skin type you have, you are perfect! See you 'write to you' next Fri-yay!
