The science of micronutrients (MN) remains at the stage of amassing factual material. Hair is a reliable and non-invasive source of information about the MN content in the body, for its metabolism is slow and only long-term disturbances in the concentration of nutrients can be reflected in it. The attention of many researchers has been drawn to the hypothesis of the influence of exogenous and endogenous factors on the hair functional status, especially with regard to essential and toxic MN. Today a tendency towards an increase in the number of paediatric patients with hair diseases ranging from excessive hair loss to various clinical forms of alopecia is observed.
Objectives. The study was aimed to identify the MN imbalance, manifested through the condition and appearance of hair, to follow structural changes in hair and to assess the influence of internal organ pathologies. 

It has been established that patients with psoriasis, which were under observation, had the skin microbial landscape of the lesions formed mainly of S. aureus, S. epidermidis, S. saprophyticus, Bacillus and Micrococcus genera. The clearest microbial contamination of the lesions has been observed in psoriatic erythroderma, slightly less accentuated skin microbial contamination has been found in patients with the widespread form of dermatitis and the presence of arthropathy, and the least number of microorganisms have been found in patients with common psoriasis without complicated phenomena.

Squamous-hyperkeratotic mycosis of feet is the most prevalent dermatological condition in type 2 diabetes patients. The cutaneous symptoms develop slowly, starting with the formation of painless blistering and hyperkeratosis in areas exposed to pressure. The fungal infection adherence is promoted by poor circulation and traumatisation of the feet skin. The selection of a suitable product containing components with distinct keratolytic and hydrating effects is one part of the problem solution.

Найбільш розповсюдженими дерматологічними захворюваннями у хворих на діабет типу 2 є сквамозно-гіперкератотична форма мікозу ступней. Шкірна симптоматика розвивається повільно, починаючи з утворення неболючих змозолілостей та гіперкератозу в ділянках, що зазнавали тиску. Приєднанню грибкової інфекції сприяє порушення кровообігу та травматизація шкіри стоп. Однією з ланок вирішення проблеми є підбір необхідного препарату, який містить компоненти с вираженими кератолітичними та гідратуючими властивостями. Метою дослідження стало вивчення клінічної ефективності бальзаму для ніг від змозолілостей та гіперкератозу з протигриб- ковим ефектом.

Laser therapy is a complex of hardware procedures that involve exposure of the skin to light energy and allows getting rid of a number of skin imperfections. The results of the therapy using the Nordlys device, the principle of operation of which is based on the theory of selective photothermolysis, were analyzed and presented. We observed 118 patients (42 men and 76 women aged 18 to 65 years) with different dermatological problems. The Dermatology Life Quality Index (DLQI) was used to determine the effectiveness of the treatment.
