The present invention describes systems and methods for treating disorders and / or conditions associated with the dermal level of the skin. Such disorders include acne, hyperhidrosis, bromhidrosis, chromhidrosis, rosacea, hair loss, dermal infection, and / or actinic keratosis. Methods generally involve administering nanoemulsions (e.g., nanoparticle compositions) comprising at least one therapeutic agent, such as botulinum toxin. In some embodiments, nanoemulsions are prepared, e.g., by high pressure microfluidization, and comprise a particle size distribution exclusively between 10 nm and 300 nm.

A non-invasive tool for skin disease diagnosis would be a useful clinical adjunct. The purpose of this study was to determine whether visible / near-infrared spectroscopy can be used to non-invasively characterize skin diseases. In-vivo visible- and near-infrared spectra (400-2500 nm) of skin neoplasms (actinic keratoses, basal cell carcinomata, banal common acquired melanocytic nevi, dysplastic melanocytic nevi, actinic lentigines and seborrheic keratoses) were collected by placing a fiber optic probe on the skin. Paired t-tests, repeated measures analysis of variance and linear discriminant analysis were used to determine whether significant spectral differences existed and whether spectra could be classified according to lesion type. Paired t-tests showed significant differences (p<0.05) between normal skin and skin lesions in several areas of the visible / near-infrared spectrum. In addition, significant differences were found between the lesion groups by analysis of variance. Linear discriminant analysis classified spectra from benign lesions compared to pre-malignant or malignant lesions with high accuracy. Visible / near-infrared spectroscopy is a promising non-invasive technique for the screening of skin diseases.

In a method for non-therapeutic or therapeutic photodynamic treatment of a skin target area, a photosensitizer fluid incorporating a photosensitizing agent or a precursor for a photosensitizing agent is delivered to the target area, the photosensitizing agent having at least one absorption wavelength in a wavelength range higher than 400 nm. The target area is then exposed to light energy in a range of wavelengths comprising at least one absorption wavelength of the photosensitizing agent, the light energy being supplied to the target area in the form of at least one light pulse producing in the target area an accumulated energy density sufficient for photodynamic activation of the photosensitizing agent. The photosensitizing agent or precursor is incorporated in the photosensitizer fluid with a concentration in the range from 0.1 to 2.0% preferably from 0.1 to 0.9%, and the photosensitizer fluid is delivered to the target area in the form of a number of repeated spray doses during an overall delivery time ranging from 0.25 to 8 hours. The method can be applied to cosmetic treatments for skin rejuvenation, reduction of wrinkles, treatment of telangiectasia or removal of hair as wells a medical treatment of dermatologic diseases such as acne vulgaris, acne scars, rosacea, psorieasis, actinic keratoses, basal cell carcinoma, Bowen's disease or eczema.
