US 11,141,374 B2 · Natural skin care compositions and methods for treating oxidative stress and restoring skin health

Abstract

The present disclosure is directed to a composition intended for application onto human skin suffering from oxidative stress, the composition comprising: (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; (3) a dermatologically acceptable carrier; and (4) a film former, wherein (a)-(f) are employed in amounts sufficient to neutralize existing free radicals present in the skin, while proactively priming the skin in order to enhance its ability to protect itself against free radical aggression caused by exposome-induced oxidative stress and dry skin-inducing water loss, wherein the composition is natural and free of a skin sensitizing-effective amount of an essential oil.

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;
(3) a dermatologically acceptable carrier;
and
(4) a film former;
wherein (a)-(f) synergistically neutralize existing free radicals present in the skin, while proactively priming the skin in order to enhance the skin's ability to defend itself against free radical aggression caused by exposome-induced oxidative stress and dry skin-inducing water loss, thereby improving its health and appearance;
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.

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 in order to enhance its ability to defend itself against free radical aggression caused by exposome-induced oxidative stress and dry skin-inducing water loss;
(3) an emulsifier;
(4) a dermatologically acceptable carrier;
and
(5) a film former;
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.

and
wherein the composition is natural, free of a skin sensitizing-effective amount of an essential oil, and has a pH of from about 4.5 to about 5.5.
