Seborrheic keratosis is a skin condition whose origin is found in the keratinocytes. The keratinocytes are cells within the epidermis of the skin which are responsible for providing a physical barrier against viruses, bacteria, fungi and parasites. When the skin is infected these cells secrete chemicals that direct the body’s leucocytes to the regions of infection. A variety of biologically active compounds obtained from the Aloe Vera plant have been shown to exhibit anti-fungal and anti-properties, which allow them to inhibit skin mycosis. In this sense Aloe Vera extracts can help the keratinocytes in carrying out their function when its extracts are applied as topical creams.
The seborrheic keratosis skin condition arises when the keratinocytes can no longer carry out their function due to degeneration caused by old age. The condition is characterized by the formation of circular or oval brown spots on the skin. As the condition progresses the brown lesions harden and turn dark. The wart-like scabs exhibit a paste on appearance. The spots caused by the condition are harmless and are more common with old people. This is why they are sometimes referred to as the old age barnacles.
Other common names that refer to the condition include senile warts, brown warts or basal cell papilloma. In a variant of the condition referred to as seborrheic dermatitis the brownish lesions are found on the face, scalp, chest and upper back. In another variant known as solar lentigines brown lesions are found only on parts of the body normally exposed to the sun. Another variant of the condition is characterized by lesions on the face, neck and chest.
Aloe Vera has shown to be quite effective in alleviating symptoms in the seborrheic dermatitis variant of Seborrheic keratosis. This is because the condition affects regions of the body with an abundance of oil glands such as the face, scalp, groin and chest. With age this oil glands fail to function properly which leads to dry skin. A subsequent result is the formation of the reddish brown lesions.
Aloe Vera extracts help to keep the skip moisturized as well as in keeping the pores of the oil glands open. In a clinical trial report released in March 1999, Aloe Vera extracts were shown to offer significant symptomatic relief on areas affected by seborrheic dermatitis. This was mainly due to it ability to keep skin moisturized alleviating scaliness. In 58% of the total number of participants marked improvement in their condition was noted. The Aloe Vera used in the clinical study was applied as a topical cream.
Additional benefits of Aloe Vera on the skin include treatment of psoriasis in which the skin becomes so dry that it cracks and starts to bleed. Aloe Vera extracts are also known to add shine to skin by helping to maintain pH levels. It helps skin to regenerate faster allowing for a firmer healthy look.
