Abstract

Compositions intended for application onto human skin damaged by oxidative stress can include (1) a mixture of at least: (a) a leaf extract of Aristotelia chilensis; (b) a leaf extract of Buddleja globosa; (c) a leaf extract of Ugni molinae; (d) optionally, a bark/seed extract of Entada phaseoloides; (e) optionally, a blend of Pfaffia paniculata, Ptychopetalum olacoides, and Lilium candidum extracts; and (f) at least one humectant; (2) an emulsifier; and (3) a dermatologically acceptable carrier, wherein (a)-(f) are employed in amounts sufficient to synergistically neutralize existing free radicals present in the skin, while proactively priming the skin by repairing and/or protecting its Stratum corneum without unduly impairing the Stratum corneum's acid mantle, and wherein the composition is natural, free of a skin-sensitizing amount of an essential oil, and has a pH ranging from about 4.5 to about 5.5.

Dependent claims

A composition for application onto human skin, the composition comprising:

(1) a mixture of at least:
(a) about 1 to about 10% by weight of a leaf extract of Aristotelia chilensis;
(b) about 0.5 to about 3% by weight of a leaf extract of Buddleja globosa;
(c) about 0.5 to about 3% by weight of a leaf extract of Ugni molinae;
(d) optionally, about 1 to about 5% by weight of a bark/seed extract of Entada phaseoloides;
(e) optionally, about 1 to about 5% by weight of a blend of Pfaffia paniculata, Ptychopetalum olacoides, and Lilium candidum extracts;
and
(f) about 1.0 to about 8.0% by weight of at least one humectant;
(2) an emulsifier;
and
(3) a dermatologically acceptable carrier,
wherein (a)-(f) synergistically neutralize existing free radicals present in the skin, while proactively priming the skin by repairing and/or protecting its stratum corneum without unduly impairing the Stratum corneum's acid mantle,
wherein the composition is natural, free of a skin-sensitizing amount of an essential oil, and has a pH ranging from about 4.5 to about 5.5 and
wherein the composition is in the form of a solution, suspension, lotion, cream, gel, spray, ointment, foam, serum, or combination thereof.

11 more elements

A composition intended for application onto human skin, the composition comprising:

(1) a preservative system comprising:
(a) from about 1 to about 5% by weight of a Lactobacillus ferment;
(b) from about 1 to about 5% by weight, of a Lactobacillus and Cocos nucifera fruit extract;
(c) up to about 0.5% by weight of salicylic acid;
(d) from about 0.1 to about 0.5% by weight of at least one salt of a weak acid;
and
(e) from about 1 to about 10% by weight of a petroleum-free 1,3-propanediol;
(2) a mixture of at least:
(f) about 1 to about 10% by weight of a leaf extract of Aristotelia chilensis;
(g) about 0.5 to about 3% by weight of a leaf extract of Buddleja globosa;
(h) about 0.5 to about 3% by weight of a leaf extract of Ugni molinae;
(i) optionally, about 1 to about 5% by weight of a bark/seed extract of Entada phaseoloides;
(j) optionally, about 1 to about 5% by weight of a blend of Pfaffia paniculata, Ptychopetalum olacoides, and Lilium candidum extracts;
and
(k) about 1.0 to about 8.0% by weight of at least one humectant, wherein (f) (k) synergistically neutralize existing free radicals present in the skin while proactively priming the skin by repairing and/or protecting its stratum corneum without unduly impairing the Stratum corneum's acid mantle;
(3) an emulsifier;
and
(4) a dermatologically acceptable carrier, wherein the composition is natural, free of a skin sensitizing-effective amount of an essential oil, and has a pH ranging from about 4.5 to about 5.5.
