Cosmetology and Beauty Therapy

Mild redness and swelling (erythema and edema) are normal, temporary responses to the heat or chemical destruction of the hair follicle during electrolysis.

Hair follicle shape determines the texture of the hair shaft. A round follicle produces straight hair, while oval or flatter follicles result in wavy or curly hair.

An ulcer is an open sore on the skin or mucous membrane. Keloids and cicatrix are types of scar tissue, and urticaria refers to hives.

An ingrown hair is typically a minor mechanical issue. Freeing the hair allows it to grow normally and the skin to heal without further intervention.

During menopause, hormonal shifts often lead to terminal hair growth in androgen-sensitive areas, most commonly the chin and upper lip.

Scleroderma is a chronic disease characterized by the hardening and thickening of the skin and connective tissues.

Terminal hair growth in women is primarily driven by androgens. An excess of these hormones can lead to hirsutism.

A scale is an accumulation of epidermal flakes, often seen in conditions like psoriasis or dry skin.

Insulated probes are designed to protect the surface of the skin from thermal damage by concentrating the heat at the tip of the probe, thus reducing trauma to the epidermis.

A naevus (or nevus) is the technical term for a birthmark or a mole, which is a localized malformation of skin tissue.

Erythema (redness) is a normal, temporary inflammatory response to treatment. While hyperpigmentation and hypopigmentation are significant concerns for darker skin, erythema is expected and of least concern.

Using a needle that is too large for the follicle can cause mechanical trauma, leading to bruising (ecchymosis) or other skin damage.

Changes in color (black/slate) and irregular shapes are classic warning signs of melanoma, a serious form of skin cancer.

The dermis contains collagen and elastin fibers, which are responsible for the skin's strength and elasticity.

Moist skin can be problematic because it can cause the current to spread or short-circuit, potentially leading to discomfort or ineffective treatment. Excessive moisture on the skin surface can interfere with the precision of the electrical current.
