The dermatologist diagnoses and treats a range of skin, hair and nail diseases and lesions. Among the most frequent are acne, rosacea, pigmentation problems, eczema, psoriasis, hair loss, nail fungus, moles, warts etc.
Acne affects not only adolescents but adults too. It is characterised by the presence of comedones (blackheads) and microcysts (whiteheads) caused by blocked sebaceous glands. These lesions can become inflamed and infected, evolving into papules and pustules. Acne treatment must be adapted according to the different types of lesions present and often requires a combination of treatments.Read more
Sometimes if there are deep acne scars, this will require skin resurfacing treatments, either by laser or by fractional radiofrequency microneedling, until the skin is smooth again. After several sessions, this makes it possible to erase the superficial scars and greatly reduce the deeper scars.
Rosacea is a skin disorder which manifests itself through redness on an adult’s face. It takes on different forms:Read more
- couperose, a vascular form characterised by redness and dilated blood vessels (telangiectasis), especially on the cheeks, nose and chin;
- papular or papulopustular which shows up as “pimples” on a red surface.
These “pimples” are sometimes mistaken for acne pimples but do not have the same origin. Unlike acne, rosacea favourises increased colonisation of the pores by a small skin parasite called the demodex mite. Rosacea is often wrongly viewed as a sign of excessive alcohol consumption, which can have a strong psychological impact on those suffering from it.
The treatment depends on the clinical type: redness and telangiectasis are treated by laser, while for papular or papulopustular rosacea, medical treatment is added.
Melasma or the “mask of pregnancy” is a skin disease recognisable by the gradual appearance of dark (pigmented) patches on the face, especially on the cheeks, forehead and upper lip.Read more
Treatment for melasma consists of applying sunscreen lotion with a high SPF, combined with depigmenting creams (hydroquinone-based, to name just one). Monitoring this condition must be done over the longer term, since recurrences are frequent, making this disorder especially psychologically stressful.
Where topical treatment is not successful or if there is a recurrence, therapeutic options include chemical peels or laser treatments: carbon peel, laser toning (skin smoothing laser) or micro ablative laser to increase the penetration of depigmenting agents.
Solar lentigos are brown spots that appear with age on areas exposed to the sun (face, cleavage and the backs of the hands).Read more
Vitiligo appears as white spots, caused by depigmentation of the skin, most commonly on face and hands, but can affect other parts of the body (armpits, knees, genitals, etc.).Read more
The success of the treatment depends in part on the age and location of the lesions. Recent patches limited to the facial area usually respond well to topical medications (corticosteroids, vitamin D). Faced with more persistent or generalised forms, phototherapy provides a potential response. Unfortunately, the patient does not always achieve complete repigmentation. Specialised cosmetics can compensate for the loss.
Eczema is an inflammatory skin disease that manifests itself by redness (which sometimes ooze) and flaking of the skin. Its causes are multiple, sometimes combined: genetic factors, irritation of the skin, allergies etc.Read more
Psoriasis is a skin disease that manifests itself as red, scaly patches, most often on the elbows, knees, legs, back and scalp. Quite common, but not contagious, it affects the quality of life of those affected.Read more
Hair loss (or alopecia) presents in different types: diffuse alopecia, androgenetic alopecia and alopecia areata.Read more
Androgenetic alopecia is genetically determined, linked to the action of androgens (male hormones): this is what we call male pattern baldness. It is not a disease, but a natural evolution of the life of the hair. It affects 15% of men at age 20 and up to 50% of men at age 50. Medical treatments exist to slow this development and good results can be obtained if the problem is treated early enough, when the loss is not too serious.
In women, this form of hair loss is less common and rarely occurs before the age of 40, with a greater or lesser aesthetic impairment depending on the degree of loss of capillary density. Apart from anti-androgen treatments, the injection of PRP into the scalp – a treatment used only recently in this field – is particularly effective.
Nail disorders. Among the most common, nail fungus, traumatic onycholysis and nail psoriasis show very similar clinical signs. Diagnosis helps avoid unnecessary treatments.
