1. Skin scars
Scars : are areas of fibrous tissue (fibrosis) that replace normal skin after injury. A scar results from the biological process of wound repair in the skin and other tissues of the body. Thus, scarring is a natural part of the healing process

2. Types of scars
Acne scars:
there are many types of acne scars, ranging from deep pits to scars that are angular or wavelike in appearance. Treatment options depends on the type of acne scar.

3. Types of scars Keloid scars :
they result from aggressive healing process. They extend beyond the original injury. Treatments include surgery to remove the scar, steroid injections, or silicone sheets to flatten the scar.

4. Types of scars Hypertrophic scars:
these are raised, red scars that are similar to keloids but do not go beyond the boundary of injury. Treatment include injections of steroids to reduce inflammation or silicone sheets, which flatten the scar.

5. Scar types Contracture scars:
results from burns, these scars tighten the skin, which can impair your ability to move, contracture scars may also go deeper, affecting muscles and nerves

6. Treatment of Scars
1.Collagen induction therapy: involves repeatedly puncturing the skin with tiny, sterile needles. 2. chemical peels: used in treatment of superficial acne scars. 3. filler injections: filler injection of collagen to raise the level of the scars to the level of the surrounding tissue. 4. laser treatment 5. surgery 6. steroids: helps to flatten and soften the appearance of keloid or hypertrophic scars. 7. radiotherapy 8. vitamins 9. creams and ointments

7. Anti scar creams
Mebo: is a Chinese herbal compound that contains: sesame oil and bees wax it’s very oily and has a strong odor the use of mebo reduces scaring and redness it should be applied every 4-6 hours to exposed wounds hours to covered wounds also reduces infection risk and decreases treatment time, helps return elasticity to damaged skin.
Used for: acne scars, scars caused by surgery, burns, dermatitis.
It also contains cactus extract which are rich in linoleic acid, vitamin E, and tyramine.

8. Mechanism of action
The exact mechanism of action of MEBO has not been fully elucidated, but it is thought that this oil-based ointment provides a moist environment for epithelial regeneration to occur with the added anti-inflammatory effects of beta-sitosterol and antimicrobial effects of berberine.

9. solcoseryl
Solcoseryl is a tissue metabolism activator, chemically and biologically standardized - deproteinised, non antigenic and apyrogenic hemodialized extract form the blood of healthy young calf. It contains large amounts of natural low molecular weight substances like glycolipids, nucleosides, nucleotides, amino acids, oligopeptides, irreplaceable microelements, electrolytes, intervening products of carbohydrate and fat metabolism.
It stimulates cellular oxygen consumption, especially in cases of hypoxia, normalizes metabolism, glucose transport, stimulates ATP synthesis, accelerates regeneration in reversible cell and tissue damage. Stimulates angiogenesis, promotes revascularization of ischemic tissue, creation of conditions for collagen synthesis and growth of new granulation tissue, accelerates revitalization and wound coverage. Possesses membrane-stabilizing and cell-protecting properties. Indications: burns, ulcers and venous insufficiency.

15. Phenytoin 10%
Topical phenytoin is a powerful wounds healing, phenytoin showed better therapeutic and cosmetic results by healing faster with more intense epithelization in wounds in comparison with cream (control) phenytoin application resulted in a smaller area and a shorter healing time also the intesnsity of exudates, bleeding. and the epithelization were more intense in phenytoin treated wounds, it stimulates collagen deposition, fibroblast proliferation, glucocorticoids antagonism and has anti bacterial activity.
