Skin Freckle

Skin Freckle

Skin Freckle: Features/ sign of skin freckles are: small size, few mm at most flat and smooth texture brown marks discoloration pigmentation disorder arising on the face and other sun exposed areas, such as back, arm, leg, especially for sunbather They are most often seen in fair skinned people, especially those with red hair, the Caucasian, fairer Asian but also, they are an inherited characteristic that sometimes affects darker skin types as well.

Terminology

The medical term for this type of freckle is ephilis (plural ephilides). The colour is due to pigment accumulating in the skin cells, called the keratinocytes.

 

 

 

 

Melanin pigment production variation during different seasons

Freckle Lentigines
The melanocyte don’t produce much melanin when there is low amount of sun ray, especially during the winter months, or when people do not go outside due to cold. Lentigines tend to persist for long periods and don’t disappear in the winter (though they may fade).

Pigment cell behavior

  • The melanin, is the pigment, is made by cells called melanocytes. The melanocyte don’t produce much melanin when there is low amount of sun ray, especially during the winter months, or when people do not go outside due to cold.
  • but produce more when exposed to the sun, abundant during the summer, where every one goes for sunbath. Alternatively, people getting more sun unintentionally despite using all the protection during summer.

 

 

Skin Freckle: Melanin diffusion/location, in keratinocyte, not melanocyte The melanin is diffused into the surrounding skin cells, called keratinocytes. The colour of ephilides is due to localised accumulation of melanin inside the keratinocytes, NOT in the melanocyte as in lentigines.

Dark Freckle:
Melanin diffusion/location, in keratinocyte, not melanocyte
The melanin is diffused into the surrounding skin cells, called keratinocytes.
The colour of ephilides is due to localised accumulation of melanin inside the keratinocytes, NOT in the melanocyte as in lentigines.

 

 

Melanin diffusion/location, in keratinocyte, not melanocyte

  • The melanin is diffused into the surrounding skin cells, called keratinocytes.
  • The colour of ephilides is due to localised accumulation of melanin inside the keratinocytes, NOT in the melanocyte as in lentigines.

 

Melanin pigment particles location in different situation

Freckle Lentigines
Melanin is dispersed inside keratinocytes cell, which is located at the most surface layer of epidermis. Melanin is contained inside deeper sited melanocyte cell, at deepest part of epidermis

 

 

 

 

Dark Freckle: Seasonal variation of pigment intensity Ephilides are more prominent in summer but fade considerably or disappear in winter as the keratinocytes are replaced by new cells. As the person ages this type of freckle generally become less noticeable. Apart from sun protection, no particular treatment is necessary.

Dark Freckle.
Seasonal variation of pigment intensity;
1. Ephilides are more prominent in summer but fade considerably or disappear in winter as the keratinocytes are replaced by new cells.
2. As the person ages this type of freckle generally become less noticeable.
Apart from sun protection, no particular treatment is necessary. NOTE: Freckle is found commonly in exposed part like the limb. trunk, face. 

Seasonal variation of pigment intensity

  • Ephilides are more prominent in summer but fade considerably or disappear in winter as the keratinocytes are replaced by new cells.
  • As the person ages this type of freckle generally become less noticeable. Apart from sun protection, no particular treatment is necessary.
