Definitions

  • Niacin also known as vitamin B3 is the common name for nicotinic acid.
  • the physiologically active form of niacin is niacinamide.
  • Niacin and niacinamide (nicotinamide or nicotinic acid amide) function in the body as a component of two coenzymes: nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP).
  • NAD nicotinamide adenine dinucleotide
  • NADP nicotinamide adenine dinucleotide phosphate
  • vitamin B3 compounds act by retarding melanin dispersion or distribution into the epidermis.
  • vitamin B3 compounds at concentrations above 10%, preferably above about 20%.
  • Stretch-marks also termed striae cutis distensae or other similar striae of the skin
  • Stretch-marks are basically defined as the slightly depressed lines on the skin that follow prolonged stretching of the skin. Stretch-marks typically arise from stretching caused by pregnancy, obesity, etc. Stretch-marks commonly appear on the abdomen, breasts, and thighs, although other body sites may be involved.
  • the present invention relates to methods of treating stretch-marks by administering a safe and effective amount of a skin care composition comprising: a), at least above about 10% of a stretch-mark fading agent selected from the group consisting of vitamin B3 compounds and mixtures thereof; and b). a dermatologically acceptable carrier for said vitamin B3 compound.
  • the present invention further relates to articles of manufacture comprising a skin care composition comprising from about 0.1% to about 40% of a vitamin B3 compound in a package for said skin care composition in association with the information about and/or instructions on the use of vitamin B3 compounds to treat stretch-marks.
  • safety and effective amount means an amount of a compound or composition sufficient to significantly induce a positive benefit, preferably a positive skin appearance or feel benefit, including independently the benefits disclosed herein, but low enough to avoid serious side effects, i.e., to provide a reasonable benefit to risk ratio, within the scope of sound judgment of the skilled artisan.
  • the skin moisturizing compositions used in the present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well any of the additional or optional ingredients, components, or limitations described herein.
  • compositions used in the present invention comprise a safe and effective amount of a natural or synthetic vitamin B3 compound.
  • the compositions used in the present invention preferably comprise from above 10% to about 50%, more preferably from about 12% to about 50%, even more preferably from about 20% to about 40% of the vitamin B3 compound.
  • vitamin B3 compound means a compound having the formula:
  • R is - CONH2 (i.e., niacinamide), - COOH (i.e., nicotinic acid) or - CH2OH (i.e., nicotinyl alcohol); derivatives thereof; and salts of any of the foregoing.
  • CONH2 i.e., niacinamide
  • COOH i.e., nicotinic acid
  • CH2OH i.e., nicotinyl alcohol
  • Exemplary derivatives of the foregoing vitamin B3 compounds include nicotinic acid esters, including non-vasodilating esters of nicotinic acid, nicotinyl amino acids, nicotinyl alcohol esters of carboxylic acids, nicotinic acid N-oxide and niacinamide N-oxide.
  • Suitable esters of nicotinic acid include nicotinic acid esters of C1-C22, preferably C1-C16, more preferably C1-C6 alcohols.
  • the alcohols are suitably straight-chain or branched chain, cyclic or acyclic, saturated or unsaturated (including aromatic), and substituted or unsubstituted.
  • the esters are preferably non- rubifacient.
  • non-rubifacient means that the ester does not commonly yield a visible flushing response after application to the skin in the subject compositions (the majority of the general population would not experience a visible flushing response, although such compounds may cause vasodilation not visible to the naked eye).
  • nicotinic acid material which is rubifacient at higher doses could be used at a lower dose to reduce the rubifacient effect.
  • Non-rubifacient esters of nicotinic acid include tocopherol nicotinate and inositol hexanicotinate; tocopherol nicotinate is preferred.
  • derivatives of the vitamin B3 compound are derivatives of niacinamide resulting from substitution of one or more of the amide group hydrogens.
  • Nonlimiting examples of derivatives of niacinamide useful herein include nicotinyl amino acids, derived, for example, from the reaction of an activated nicotinic acid compound (e.g., nicotinic acid azide or nicotinyl chloride) with an amino acid, and nicotinyl alcohol esters of organic carboxylic acids (e.g., Cl - C18).
  • Specific examples of such derivatives include nicotinuric acid and nicotinyl hydroxamic acid, which have the following chemical structures: nicotinuric acid: o o
