Therapeutic compositions for enhanced healing of wounds and scars
The subject invention provides topical therapeutic compositions and methods of their use for enhanced healing of wounds, including burns, and scars of the skin. Specifically, in one embodiment, the subject invention provides materials and methods for reducing the healing time of skin wounds and for reducing the appearance of scars. The subject invention utilizes topical compositions comprising microbial growth by-products and, optionally, a topically-acceptable carrier. In specific embodiments, the microbial growth by-products are biosurfactants.
1. A topical therapeutic composition for treating and/or preventing a skin condition, the composition comprising a therapeutically-effective amount of a sophorolipid (SLP) biosurfactant, a mannosylerythritol lipid (MEL) biosurfactant, cellular components of Starmerella bombicola , cellular components of Pseudozyma aphidis , lactoferrin and a dermatologically-acceptable carrier.
2. The composition of claim 1 , further comprising one or more skin active substances selected from anesthetics, keratolytic agents, desquamating agents, keratinocyte proliferation enhancers, collagenase inhibitors, elastase inhibitors, depigmenting agents, anti-inflammatory agents, steroids, anti-acne agents, and advanced glycation end-product (AGE) inhibitors.
3. The composition of claim 1 , further comprising Aloe vera extract.
4. A wound dressing comprising a dermatologically-acceptable dressing material that has been impregnated with a composition comprising a therapeutically-effective amount of a SLP biosurfactant, a MEL biosurfactant, lactoferrin, and, optionally, dried for storage, cellular components of Starmerella bombicola , and cellular components of Pseudozyma aphidis.
5. A method for promoting the healing of a skin condition, wherein said method comprises applying a composition comprising a therapeutically-effective amount of a SLP biosurfactant, a MEL biosurfactant, lactoferrin and a dermatologically-acceptable carrier to an area of the subject's skin where such a condition exists, cellular components of Starmerella bombicola , and cellular components of Pseudozyma aphidis.
6. The method of claim 5 , which further comprises applying Aloe vera gel to said area of the subject's skin.
7. The method of claim 5 , wherein the skin condition is a wound or a scar.
8. The method of claim 7 , wherein the wound is a burn.
9. The method of claim 7 , used to prevent a wound from scarring.
10. The method of claim 7 , used to reduce the appearance of a scar.
11. The method of claim 5 , comprising applying one or more amphiphile-producing microorganisms in a live or inactive form.
12. The method of claim 5 , comprising covering the area of skin where the skin condition exists with a wound dressing that has been impregnated with the composition.
13. The composition of claim 1 , further comprising a broth resulting from cultivation of a Bacillus coagulans, Bacillus subtilis or Bacillus amyloliquefaciens bacterium.
14. The wound dressing of claim 4 , wherein the composition with which the wound dressing is impregnated further comprises a broth resulting from cultivation of a Bacillus coagulans, Bacillus subtilis or Bacillus amyloliquefaciens bacterium.
15. The method of claim 5 , wherein the composition applied to the subject's skin further comprises a broth resulting from cultivation of a Bacillus coagulans, Bacillus subtilis or Bacillus amyloliquefaciens bacterium.
