Scar Treatment Geelong
What are Scars?
A scar is a mark left on the skin after the healing of a wound or a burn. The word scar originates from the Greek word eskhara, which means scab.
A scar is devoid of skin markings and appendages such as hair follicles and sweat glands and may be skin coloured, hypo pigmented or hyper pigmented.
How do scars form?
A scar reflects how wounded skin heals. Wound healing is a dynamic process that involves the three overlapping phases of inflammation, granulation tissue formation and remodelling. The relative importance of these steps depends on the depth of tissue loss.
Partial thickness wounds which involve only the epidermis and superficial dermis without damage to skin appendages such as hair follicles, sweat glands and sebaceous glands tend to heal with minimal or no scarring although pigment changes sometimes occur.
Full thickness wounds which involve the deep dermis heal with scarring. Initially there is clot formation to halt bleeding from damaged blood vessels followed by inflammation and granulation. Contraction allows the edges of the wound to come together with scar tissue forming to replace the tissue loss.
Types of Scars
Any injury that extends into the deep dermis will result in a scar. Early scars are formed in 7 – 10 days after injury at which time they have only about 5 – 10% of the original skin strength. Over the next 6 – 12 months the wound continues to undergo remodelling to form a mature scar which eventually has about 80% of the original skin strength.
Skin wounds sometimes heal with excessive scarring to form hypertrophic scars or keloid scars. The reason for abnormal scarring is not fully known but factors involved are numerous and include skin type, genetics, site and size of wound, presence of tension on healing site, secondary infection, foreign material and hormonal status.
Can Lasers Treat Scarring?
The appearance of scars can often be reduced or modified by medical lasers. Lasers such as the Pulse Dye Laser have been used successfully for several years especially for red raised scars. Recently the result from laser treatment of scars, particularly depressed scars such as found with acne scarring, have improved significantly with the advent of fractional lasers such as the FRAXEL.
The FRAXEL laser treats the skin in a pixel like fashion and penetrates into the skin down into its deeper layers to produce more collagen and blend scars better into surrounding normal skin. A series of treatments is required with results increasing for several months afterwards.
The two commonest scar conditions that we treat at the Cosmetic and Laser Medical Centre are either acne scarring or surgical scars.
