Glandular functional and structural issues in ichthyosis

An Analysis of Structural Discontinuities and Glandular Dysfunction in Ichthyosis

From a Western medical perspective, ichthyosis is a hereditary skin disorder caused by genetic defects that lead to abnormal differentiation of epidermal keratinocytes. Clinically, it is characterized primarily by abnormal keratin proliferation; patients suffer from chronic dryness and recurrent scaling across the entire body. These scales vary in appearance, ranging from white, bran-like flakes to grayish-brown, snake-skin-like patches, or even thick, rough, lichenified plaques.

The pathological changes associated with ichthyosis center on two main issues: structural abnormalities and functional impairments. Normal skin epidermis consists of four distinct layers—the stratum corneum, stratum granulosum, stratum spinosum, and stratum basale—maintaining a stable metabolic cycle. In contrast, the epidermis of most ichthyosis patients develops only two layers: the stratum corneum and the stratum basale. The absence of the intermediate stratum granulosum and stratum spinosum disrupts the cycle of keratinocyte growth and shedding, severely compromises the skin barrier, and reduces moisture retention and resilience; consequently, the condition typically worsens in winter and improves in summer.

Regarding functional impairment, patients commonly exhibit developmental defects and dysfunction in three key structures: sebaceous glands, sweat glands, and hair follicles. Sebaceous glands fail to adequately moisturize the skin, sweat gland excretion is obstructed, and hair follicle metabolism is impeded. This leads to chronic dryness, roughness, and pigment accumulation, ultimately resulting in the characteristic "fish-scale" skin appearance—marked by thick scales, distinct fish scale lines, and a coarse texture.

Zhangjian Therapy utilizes a patented herbal bath powder fumigation technique, following a comprehensive "Scale Removal – Gland Unblocking – Skin Nourishment" protocol. First, it gently metabolizes accumulated scales on the skin's surface; it focuses on unclogging blocked sebaceous glands, sweat glands, and hair follicles, enhancing skin metabolism; finally, it nourishes cells to repair skin structure, helping the skin rebuild normal secretion, absorption, and metabolic functions.
