Personalized skin-specific topical formulations containing conditioned medium obtained from cultures of fibroblasts has been developed. Unlike other topical formulations, these formulations are specific for the recipient-skin type specific, and conditioned medium is obtained from a subject with desired skin characteristics. For example, since African American skin is known to wrinkle less and later than Caucasian skin, conditioned medium may be obtained from African American skin for application to pale skin. In another embodiment, the fibroblasts are obtained from young skin for administration to older skin. In still another embodiment, the fibroblasts are obtained from skin that does not suffer from acne or discoloration, for application to skin that is prone to acne or discoloration. Examples of skin donor selection criteria include delayed wrinkling, small pores, resistance to sunburn, resistance to acne, uniform coloration or lack of blotching or age spots and good moisture retention.

Methods and formulations are provided to reduce pigmentation in skin, using an array of compounds selected from benzimidazoles, phenylthioureas, phenyltiols, phenylamines, bi- and multicyclic phenols, thiopheneamines, and benzothiamides. The compounds preferably inhibit pigment systhesis in melanocytes through the tyrosinase pathway. The methods can be used for lightening skin, and for treating uneven skin complexions which result from hyperpigmentation-related medical conditions such as melasma, age spots, freckles, ochronosis, and lentigo. The compounds can be used medically or cosmetically.

The present invention describes compositions and methods for treating, preventing and improving hyperpigmentation, or other unwanted pigmentation of the skin, or other unwanted skin condition, such as age spots, aged skin, skin discoloration, etc., wherein the compositions include siRNA-gene silencing oligomers specific for tyrosinase. The compositions are used to treat a broad variety of pigmentation conditions, and are preferably applied to the skin, or are delivered by directed means to a site in need thereof.

A composition, a method, and a kit are provided for chemical skin peeling, based on nano-structured thixotropic inorganic gels, which have a higher potency and are less irritant of the conventional peeling formulations. The gels of the invention can easily be applied on the skin, where they form a stable, uniform layer, that doesn't strain. The kit comprises by a defatting gel, different types of peeling gels and a neutralizing gel. The defatting gel is characterized by a markedly enhanced defatting capacity in comparison to the conventional products, because the sebum solubilized by the solvent is strongly adsorbed on the huge surface of the nano-structured material of the gel. The peeling gels are based on conventional peeling compounds, such as glycolic acid, trichloroacetic acid, pyruvic acid, salicylic acid, Jessner solution, but the presence of nano-structured material strongly increases the peeling effect, allowing the use of lower concentrations of peeling compound, with only minimal skin irritation for the user. The neutralizing gel is characterized by a colour change that allows the operator to verify in real time the neutralization of the peeling agent on the treated skin surface. All the gels of the invention can be easily removed from the skin after the treatment. The thixotropic gels of the invention can be used in chemical skin peeling for the treatment of various cosmetic conditions and dermatological disorders, including dry skin, acne, dandruff, keratoses, age spots, wrinkles and disturbed keratinisation.

Disclosed is a method for modelling age-related traits of a face, from a picture of the face, wherein the age-related traits are either wrinkles or age spots, the method including: for each age-related trait of the face of the same nature, generating a vector including parameters of shape and appearance of the trait; and generating, from the generated vectors, a single representation vector modeling the age-related traits of the same nature in the face. The single representation vector stores information regarding the number of traits in the face and joint probabilities, over the face, of the shape and appearance features of the traits.

The invention discloses application of epicatechin to antagonistic beta amyloid protein aggregation, cognition and memory ability improvement and age pigment reduction. AD (Alzheimer's disease) belongs to a neurodegenerative disease using nerve cell fiber entanglement, beta amyloid protein (A beta) plaque deposition and cognitive function reduction as pathological features, wherein the A beta protein extracellular toxicity accumulation is regarded as one of the major link of the occurrence of the AD. The effect that the epicatechin can obviously inhibit the fiber formation through the beta amyloid protein aggregation, inhibit the formation of a beta secondary structure, improve the space memory study capability of AD mice, and obviously clear the amyloid plaque in the APP/PS1 dual transgenic AD model mouse brain tissue is discovered. The result shows that the epicatechin can be applied to the treatment of AD and relevant medicine research and development.
