Seborrheic Dermatitis

Seborrheic dermatitis is an Inflammatory chronic condition characterized by erythema, flaking and itching papulo-squamous lesions, and in some cases, hair loss. Skin areas characterized by a high presence of sebaceous glands are the most typical locations of this pathology: scalp, back of the ears, nose, eyebrows, and chest. Seborrheic dermatitis is considered one of the most common skin disorders and can affect to every human group regardless of their age: enfants, children, teenagers, and adulthood, affecting more men than women. Its incidence peaks during three age periods: in the first three months of life, during puberty, and in adulthood with an apex at 40 to 60 years of age. Seborrheic dermatitis affects approximately 3% of the general population and up to 42% of infants in the first three months of life may have the condition. The cause is certainly complex but a central role is played by an alteration in the skin sebum, the microbiota and in the immune response. This alteration of the microbiome contributes to the formation of the inflammatory framework causing itching, redness and desquamation, classical symptomatology of seborrheic dermatitis. The inclusion of adjuvants that help balance the skin’s microbiome is recommended.
