A cosmetic method for modulating pigmentation in a subject includes administering a modulator of angiotensin-converting enzyme 2 (ACE2 modulator) to the subject. The ACE2 modulator can be an inhibitor of angiotensin-converting enzyme 2 (ACE2 inhibitor), in which case, the ACE2 inhibitor can be administered to increase pigmentation in the subject. The ACE2 modulator can also be an activator of angiotensin-converting enzyme 2 (ACE2 activator), in which case the ACE2 activator can be administered to decrease pigmentation in the subject. The treatment of inflammatory skin disease can also be achieved by inhibition of angiotensin-converting enzyme 2.

The invention relates to functionalized polymers, a process for producing functionalized polymers and the use of functionalized polymers, especially in the field of personal care.

One variation of a method includes: accessing a skin type of a user; predicting a first set of locations occupied by the user during a first future time interval; based on historical ultraviolet irradiance data and the first future time interval, calculating a first predicted unprotected ultraviolet radiation exposure of the user during the first future time interval; calculating a maximum allowable ultraviolet radiation exposure for periods within the first future time interval based on the skin type of the user; calculating a first minimum sun protection factor predicted to reduce the first predicted unprotected ultraviolet radiation exposure to less than the maximum allowable ultraviolet radiation exposure; selecting a first sunscreen formula characterized by a first sun protection factor greater than the first minimum sun protection factor; and shipping the first volume of the first sunscreen formula to the user prior to the first future time interval.

The disclosure relates generally to insect repellent compositions and methods for using the same.

A topically applicable chemical peel composition for home use having from about 4% to about 13%, by weight, of alpha hydroxy acid, from about 0.1% to about 2.0%, by weight, of salicylic acid, from about 0.1% to about 2.0%, by weight, of phenylethyl resorcinol and balance essentially dermatologically acceptable liquid solvent comprising water and ethanol, the ethanol present from about 10 to about 90 wt %. In addition, a chemical skin peel regime or regimen including topical application onto the skin is also disclosed.

Described are compositions containing quinones that show activity in enhance DNA repair and/or prevent damage to DNA. The quinones are thymoquinone, lapachol, myrtucommulone C, or mixtures thereof, and can be formulated into cosmetic compositions for topical administration to a subject in need thereof. The cosmetic compositions can also include sunscreens, surfactants, sunless tanning agents, desquamation agents, antiperspirants, colorants, preservatives and mixtures; and a cosmetically acceptable carrier. The compositions should find use in methods for treating the signs of ageing in mammals via topical application to the skin or hair of the mammals.

The application provides compositions, in particular dermatological compositions comprising extracts from argan tree for the treatment and prevention of dermatological conditions. More particularly, a composition comprising argan oil (AO), argan leaf extract (AL) and argan stem cells (ASC) is provided. Further provided is a method for reducing photoaging of the skin of a subject due to exposure to UV radiation which comprises applying the composition of the invention to the subject prior to exposure to UV radiation.

Compounds, compositions, and methods for modulating skin pigmentation and treating or preventing UV-induced skin damage, erythema, aging of the skin, sunburn, and hyperpigmentation in a subject. Malassezia-derived compounds and/or chemical analogs thereof, compositions that comprise such compounds, and methods of treating by administering the compounds and compositions, including methods of inducing melanocyte apoptosis, and modulating arylhydrocarbon receptor (AhR) activity, melanogenesis, and melanin concentration.

The present invention relates to a mixture comprising (i) one or a plurality of 1,2-alkane diols with 5 through 8 carbon atoms and (ii) one or a plurality of ammonium-, sodium- or potassium-R.sup.alk-sarcosinates, wherein the structural element R.sup.alk represents alkanoyl, alkenoyl or alkadienoyl with 12 through 22 carbon atoms, and optionally (iii) one or a plurality of sodium- or potassium-C10-C16-alkyl-sulfoacetates. The invention further relates to particular compositions and cosmetic preparations, in particular body care products, containing said mixture or composition and methods of production thereof. The present invention further relates to the use of said mixture as solubilizer and for increasing the transparency or decreasing the turbidity of a preparation containing one or a plurality of further organic substances.

An injectable hyaluronic acid composition including a hyaluronic acid; a local anesthetic selected from the group of amide and ester type local anesthetics or a combination thereof; and an ascorbic acid derivative in an amount which prevents or reduces the effect on the viscosity and/or elastic modulus G of the composition caused by the local anesthetic upon sterilization by heat. Further, the medical and non-medical, such as cosmetic, use of such a composition, and to a method of manufacturing such a composition.
