Stretch marks
Stretch marks are scar-like streaky areas that appear in overstretched skin. Underlying tissue
expansion is the most common cause, so they develop most often during the growth spurt in
adolescence and on the expanding abdomen in the third trimester of pregnancy.
They can also occur in body builders, as a consequence of rapid weight gain, and in some medical
conditions where the skin is exposed to excess amounts of a hormone called cortisol. Early stretch
marks are usually red or purple. Over time, stretch marks lose their colour and become white or
silvery in appearance.
Structure of the skin
The visible layer of skin (epidermis) is made from several sheets of cells and functions as a barrier
for the underlying tissue. Epidermal cells born in the bottom sheet push up through the layers to
replace old, dead skin cells that are constantly being shed. The epidermis also contains melanin –
the pigment responsible for skin colour.
Beneath the epidermis is the dermis. This deeper layer contains sweat glands, sebaceous glands,
hair follicles, blood vessels and nerves. The dermis is made from two types of fibre, being collagen,
which gives the skin its strength, and elastin, which provides skin with its elasticity.
Development of a stretch mark
A stretch mark is formed when:
• The skin is stretched as a consequence of underlying tissue expansion.
• There is an inflammatory reaction in the skin that is responsible for the characteristic red or
purple colour.
• The inflammation eventually fades and is replaced by scar tissue. This produces a thinned
epidermis, loss of dermal elastin, and a replacement of the dermis by abnormally dense
collagen fibres.
• The scarring is characteristically white or silvery in appearance and permanent.
Prevention and treatment of stretch marks
Evidence suggests that the application of creams and lotions can't prevent stretch marks. However,
not all preventative treatments have been evaluated, and some treatments have shown promise in
individual studies.
Stretch marks naturally fade and usually become less conspicuous over time, so in many cases,
treatment may not be necessary. Various treatments have been used in the management of red,
purple or white stretch marks. While some creams may improve the appearance of early stretch
marks, lasers and IPL therapy may also be beneficial.

Stretch Marks
Stretch Marks are scar-like areas that appear in overstretched Streaky Skin. Underlying tissue
Expansion is the Most common Cause, so they develop Most often during the growth Spurt in
adolescence and on the expanding abdomen in the third trimester of Pregnancy.
They Can also occur in Body Builders, as a consequence of Rapid weight gain, and in. Some Medical
Skin is exposed to the conditions where excess amounts of a Called Hormone cortisol. Early stretch
Marks are usually Red or Purple. Over time, Lose their stretch Marks and Become Colour White or
silvery in appearance.
Structure of the Skin
The Skin of visible layer (epidermis) is Made from several Sheets of cells and functions as a Barrier
for the underlying tissue. Born in epidermal cells Push up the bottom Sheet Through the layers to
replace Old, Dead Skin cells that are constantly being Shed. The epidermis also contains melanin -
the pigment responsible for Skin Colour.
Beneath the epidermis is the dermis. This deeper layer contains Sweat glands, sebaceous glands,
Hair follicles, Blood vessels and nerves. The dermis is Made from Two types of Fibre, being Collagen,
which gives the Skin its strength, and elastin, which provides Skin with its elasticity.
Development of a stretch Mark
A stretch Mark is formed when:
• The Skin is stretched as a consequence. Expansion of underlying tissue.
• There is an inflammatory Reaction in the Skin that is responsible for the characteristic Red or
Purple Colour.
• The inflammation eventually fades and is replaced by scar tissue. This produces a thinned
epidermis, Loss of dermal elastin, and a Replacement of the dermis by Abnormally dense
Collagen Fibres.
• The scarring is characteristically White or silvery in appearance and Permanent.
Prevention and Treatment of stretch Marks
Evidence suggests that the Application of creams and. lotions can not prevent stretch marks. However,
not all preventative treatments have been evaluated, and Some treatments have shown Promise in
individual Studies.
Stretch Marks Fade naturally and usually less conspicuous Become over time, so in many Cases,
Treatment May not be necessary. Various treatments have been used in the Management of Red,
Purple or White stretch Marks. While Some creams May improve the appearance of Early stretch
Marks, lasers and IPL Therapy May also be beneficial.
