Once the palm prints are formed, they will basically not change, but the subtle skin texture will undergo some changes.
Palmprints are a type of skin pattern, which are composed of raised skin ridges and concave skin grooves arranged regularly. Dermatoglyphs mainly exist on the palms of the hands, soles of the feet, as well as the fingers and toes. They are individual specific and lifelong. Once the palmar lines are formed, they will basically not change.
In fact, although the palm prints are basically fixed, the subtle skin texture does undergo some changes. However, this change is not directly related to internal diseases of the body, but is caused by aging of the skin surface or local changes. Changes in moisture and oil cause problems such as deepening of skin texture, wrinkles, dryness, and chapped skin.
Endocrine changes in the body, skin diseases (such as hand eczema, contact dermatitis, palmar and plantar psoriasis), etc. will affect the skin quality of the palms, the effects of smoking, drugs and diet, as well as climate change, skin care products Application, long-term sun exposure, environmental pollution, excessive washing or exposure to dust and other allergic substances will also have some effects.

The formation of human palm prints:
In the early stages of embryonic development, the skin lines of the palms have gradually formed. The production of striae begins in the 10th week of pregnancy and evolves from a primitive structure in the embryo called the palm pad. The pattern of striae begins to be visible on the fetal skin surface at 19 weeks of pregnancy, and thereafter the pattern of striae will no longer change.
There are currently three hypotheses to explain the formation of fingerprints: the mechanical hypothesis represented by the folding hypothesis, the neural hypothesis and the fibroblast hypothesis. How striae form is still unclear, but according to current research findings, genetic, developmental and environmental factors jointly create individual-specific striae.
