The application of L-arginine and its derivatives to the skin causes beneficial effects of wound healing, increasing erectile function and increased growth of hair when applied in sufficient quantity to the skin. A hostile biophysical agent may be combined with the L-arginine to increase its absorption into the skin. The desired concentrations of the hostile biophysical agent is increased when concentration of L-arginine is less than 20% of the concentration of the substance applied to maximize its effect.

I claim: 1. A method of increasing localized blood flow in tissues comprising the steps of: applying topically to the skin a delivery vehicle comprising L-arginine hydrochloride at a concentration of 0.25% to 25% by weight, wherein the L-arginine hydrochloride is contained in a package selected from the group consisting of liposomes, emulsions of collagen, collagen peptides and combinations thereof, wherein the delivery vehicle further comprises an ion donor selected from the group consisting of sodium chloride, choline chloride, potassium chloride, lithium chloride and magnesium chloride and mixtures thereof, and said ion donor is present in an amount sufficient to create a high ionic strength environment able to cause the L-arginine hydrochloride to migrate from the delivery vehicle to the skin where the delivery vehicle is applied, wherein (i) said ion donor concentration in the delivery vehicle is 10% to 90% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 0.25% to below 5% by weight, (ii) said ion donor concentration in the delivery vehicle is 5% to 80% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 5% to 15% by weight, and (iii) said ion donor concentration in the delivery vehicle is 5% to 50% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is greater than 15% to 25% by weight. 2. A topical delivery vehicle for application to the skin comprising: L-arginine hydrochloride at a concentration of 0.25% to 25% by weight, wherein the L-arginine hydrochloride is contained in a package selected from the group consisting of liposomes, emulsions of collagen, collagen peptides and combinations thereof, wherein the delivery vehicle further comprises an ion donor selected from the group consisting of sodium chloride, choline chloride, potassium chloride, lithium chloride and magnesium chloride and mixtures thereof, and said ion donor is present in an amount sufficient to create a high ionic strength environment able to cause the L-arginine hydrochloride to migrate from the delivery vehicle to the skin where the delivery vehicle is applied, wherein (i) said ion donor concentration in the delivery vehicle is 10% to 90% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 0.25% to below 5% by weight, (ii) said ion donor concentration in the delivery vehicle is 5% to 80% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 5% to 15% by weight, and (iii) said ion donor concentration in the delivery vehicle is 5% to 50% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is greater than 15% to 25% by weight. 3. A method of treating erectile dysfunction in a male comprising topically applying to the penis of a male with erectile dysfunction a delivery vehicle comprising L-arginine hydrochloride at a concentration of 0.25% to 25% by weight, wherein the L-arginine hydrochloride is contained in a package selected from the group consisting of liposomes, emulsions of collagen, collagen peptides and combinations thereof, wherein the delivery vehicle further comprises an ion donor selected from the group consisting of sodium chloride, choline chloride, potassium chloride, lithium chloride and magnesium chloride and mixtures thereof, and said ion donor is present in an amount sufficient to create a high ionic strength environment able to cause the L-arginine hydrochloride to migrate from the delivery vehicle to the skin where the delivery vehicle is applied, wherein (i) said ion donor concentration in the delivery vehicle is 10% to 90% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 0.25% to below 5% by weight, (ii) said ion donor concentration in the delivery vehicle is 5% to 80% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 5% to 15% by weight, and (iii) said ion donor concentration in the delivery vehicle is 5% to 50% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is greater than 15% to 25% by weight. 4. A method of promoting hair growth comprising: Delivering L-arginine hydrochloride to a selected area of the skin where hair growth is desired by topically applying to the selected area of skin where hair growth is desired a delivery vehicle comprising the L-arginine hydrochloride at a concentration of 0.25% to 25% by weight, wherein the L-arginine hydrochloride is contained in a package selected from the group consisting of liposomes, emulsions of collagen, collagen peptides and combinations thereof, wherein the delivery vehicle further comprises an ion donor selected from the group consisting of sodium chloride, choline chloride, potassium chloride, lithium chloride and magnesium chloride and mixtures thereof, and said ion donor is present in an amount sufficient to create a high ionic strength environment able to cause the L-arginine hydrochloride to migrate from the delivery vehicle to the skin where the delivery vehicle is applied, wherein (i) said ion donor concentration in the delivery vehicle is 10% to 90% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 0.25% to below 5% by weight, (ii) said ion donor concentration in the delivery vehicle is 5% to 80% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is 5% to 15% by weight, and (iii) said ion donor concentration in the delivery vehicle is 5% to 50% by weight when the concentration of L-arginine hydrochloride in the delivery vehicle is greater than 15% to 25% by weight.
