One day, you notice these bluish streaks that crisscross your skin, more pronounced than before. Should we be concerned about it or is it a natural phenomenon? Let’s decipher the causes and implications of these ships that are gaining visibility.
Bluish veins under the skin: why they are often benign
Blue veins visible on one hand
Do you notice those blue streaks on your hands, especially after an active day? Rest assured: in most situations, this phenomenon is perfectly natural and does not hide any health problems.
The phototype influences their visibility
The lighter or finer the epidermis, the easier it is to guess the venous network. If you have diaphanous or naturally thin skin, don’t panic: this skin transparency simply accentuates the “geographical map” effect of your blood vessels.
The skin thickness involved
Over the years or in very thin people, the subcutaneous adipose tissue decreases. As a result, veins go from being discreet to particularly apparent. This change is common in older people or individuals with a low body fat index.
Physical activity changes their appearance
Bodybuilders or manual workers often notice an increased protrusion of their veins during exercise. This temporary manifestation results from the increased blood flow to the muscles used. Nothing abnormal: the venous network returns to its usual appearance at rest.
Pregnancy temporarily changes circulation
During gestation, blood volume can increase by up to 50%. This physiological adaptation often makes the veins more prominent, especially at the extremities. No worries: this situation gradually resolves after the arrival of the baby.
When should these visible veins be a warning sign?
Certain peculiarities may indicate a circulatory disorder requiring special attention. Be vigilant if your veins become abnormally dilated, painful, or accompanied by unusual sensations.
Protruding veins and discomfort?

A feeling of heaviness, persistent tingling or localized discomfort could indicate an underlying venous problem. In rare cases, these symptoms herald the appearance of varicose veins in the hands, although this manifestation remains uncommon compared to the lower limbs.
Deformed or too large veins?
If some of your veins take on a tortuous appearance, become nodular or appear abnormally bulging, a medical consultation is necessary. Even in the absence of pain, these changes merit professional evaluation.
