Melanin
Melanin
is a broad term for a group of natural pigments found in most organisms. It is
produced by oxidation of the amino acid tyrosine, followed by polymerization.
The pigment is produced in a specialized group of cells known as melanocytes.
There are three types:

Melanin
is the most common having two types brown and black eumelanin. In the skin
melanogenesis occurs after exposure to ultra violet (uv) radiation causing the

Melanin
absorbs light effectively because of this property it is a said to protect skin
cell from UVB radiation damage. Reducing cancer risk like malignant melanoma.

Carotene
They are
brightly colored substances found in some fruits and animal (egg yolk). It is
yellow-orange in color and is a powerful antioxidants that helps to prevent
skin cells from oxidation damage. It is transform in the body into vitamin A,
which is essential for vision and skin.

·
Excess of
beta carotene is rare but may cause a yellow residue to appear around the nose
and eye as sebaceous secretion are used to excrete the unneeded substance.
Carotene can cause jaundice and liver dysfunction due to low presentation and
circulation.

Carotene
gives color to skin (natural color) it is found in terms and combine with
hemoglobin and melanin to produce pigmentation of all surface tissue including
the skin, mucous membrane, concentration of these substance can cause
distinctive color change in the skin or other visible body tissue. Excess can
cause crack in skin and change in color.

Poor
blood circulation can effect the skin very much reducing the out looks of the
skin e.g. in anemia patient causing the skin to look white and pale. But
moderate blood circulation will help maintain healthy skin

hemoglobin is lack in the blood (oxygen) the skin loses its pigmentation
(colors) as a result of poor blood capacity

Blood
help in supplying some organ realizing waste from the body to function well but
if not supplied might be stressed and unable to eliminate the toxins which will
pressure the lymph system (node) and become sluggish which will then be
excreted through the skin causing acne.

might be impossible and it will lead to sufficient nutrient present for skin
maintenance which can cause wrinkles and dry dead skin.

Collagen
Collagen
is a protein present in all the body organs and tissues and it provide matrix
that sustains the body structure. Its main function is to sustain tendons, skin
and cartilage. It provides integrity, firmness and elasticity to their
structure, maximizing collagen levels will keep skin supple. Collagen is
responsible for skin strength and elasticity and decrease in level might result
to wrinkles, decreasing smoothness and suppleness of skin. It can not be
absorbed by skin but through supplement. Collagen with other pigment helps in
the structure and maintenance of the skin and its nature.
