The application of matrix metalloproteinase (MMP) inhibitors to the skin inhibits the degradation of proteins found in the skin including collagen, elastin, and other basement membrane and extracellular matrix protein. MMP inhibitors may be used in both cosmetic compositions and pharmaceutical compositions for application to skin. MMP inhibitors are formulated with a cosmetically suitable vehicle or pharmaceutically acceptable excipient for application to the skin as creams, lotions, ointments, solutions, face masks, etc. As cosmetics, the inventive MMP inhibitor compositions are applied to the skin to prevent or reduce the appearance of wrinkles, pigmentation changes, loss of elasticity, or other effects associated with aging or sun damage. As pharmaceuticals, the inventive MMP inhibitor compositions may also be applied to the skin to treat or prevent a skin disease (e.g., proliferative disease, inflammatory disease).

The evolution of a skin condition over time can be useful in its assessment. In an illustrative arrangement, a user captures skin images at different times, using a smartphone. The images are co-registered, color-corrected, and presented to the user (or a clinician) for review, e.g., in a temporal sequence, or as one image presented as a ghosted overlay atop another. Image registration can employ nevi, hair follicles, wrinkles, pores, and pigmented regions as keypoints. With some imaging spectra, keypoints from below the outermost layer of skin can be used. Hair may be removed for image registration, and restored for image review. Transformations in addition to rotation and affine transforms can be employed. Diagnostic correlations with reference image sequences can be made, employing machine learning in some instances. A great variety of other features and arrangements are also detailed.

The invention provides unique and novel strains of microalgae that have been subjected to non-transgenic methods of mutation sufficient to reduce the coloration of biomass produced by the strains. Biomass produced from such strains can be used in the manufacture of baked goods, gluten free foods, beverages, high lipid algal flours, and other foods. Pigments such as carotenoids and chlorophyll can be undesirable for consumer acceptance when incorporated into foods such as mayonnaise, yogurt, and white sauces that are not traditionally associated with colors such as yellow, red, orange and green. Some pigments, such as chlorophyll, can also create undesirable taste profiles. Use of reduced pigment microalgal biomass expands the range of food products that can be manufactured with healthy lipid profiles. High protein containing biomass of the invention, also reduced in pigmentation, is also incorporated into products such as meat analogues, nutritional bars and meal replacement beverages. The reduced pigmentation microalgae also allow for incorporation of higher amounts of biomass into certain food products that could otherwise be achieved using highly pigmented microalgal biomass. Methods of generating novel reduced pigment microalgae are disclosed herein. The strains provided by the invention are also useful in the manufacture of healthy, neutral colored extracted triglyceride oils.

Methods and apparatus are described that provide the ability to estimate the diffuse reflection component of an image of tissue such as skin captured without cross-polarization. It is thereby possible to estimate skin pigmentation information from an image of skin captured conventionally, such as, for example, a total reflection image, obtained in a conventional manner by shining white light on the skin and capturing the reflected light. The image may also be a partially diffuse reflection image, such as a low quality cross-polarized image. The diffuse reflection component of a captured image can then be further processed to obtain Red and Brown pigmentation images, useful for indicating the distribution of hemoglobin and melanin, the primary chromophores of skin. Additionally, a standard captured image of skin can be analyzed to obtain an estimate of the surface reflection component of the reflected light. The surface reflection component can then be used to generate a surface reflection image, useful for showing the distribution of light on the skin and to highlight superficial features such as wrinkles, fine lines, folds, pores, texture, and visible spots.
