Facial telangiectasias are a common condition where small blood vessels just beneath the skin widen, becoming visible as tiny red threads. These often concentrate around the nose wings, cheeks, or chin. Some cases, present since childhood, are considered congenital telangiectasias. Beyond cosmetic concerns, this condition can also make the skin prone to redness and more sensitive to sun exposure, weather changes, or environmental irritants.

In your case, congenital telangiectasias can be improved with laser technology. The Nd:YAG 1064 nm long-pulsed laser is a widely used method for treating small, superficial vascular lesions on the skin.

The laser's mechanism relies on the principle of selective photothermolysis. Laser energy is absorbed by hemoglobin, a main component in red blood cells and blood vessels. Upon absorbing this energy, the dilated blood vessels undergo controlled heating, gradually shrinking and regressing over time. The body then naturally eliminates these treated vascular structures.

For congenital telangiectasias on the nose wings or cheeks, many people may see improvement from the first treatment sessions if their vascular system is small and responds well. However, the effectiveness also depends on the extent of the lesion, vessel size, and individual body response. Larger or long-standing blood vessels often require more treatment sessions to achieve optimal results.

Typically, treatment sessions are spaced about 2-4 weeks apart. Most cases require around 3-4 sessions to significantly improve telangiectasias. After treatment, the recurrence rate for congenital telangiectasias is relatively low if the patient maintains proper skin care and limits factors that damage blood vessels.

Many individuals with telangiectasias also experience persistent skin redness, especially on the cheeks. Their skin often appears flushed, similar to sun exposure, or blushes easily with temperature changes. Doctors can use the Nd:YAG 1064 nm long-pulsed laser in an appropriate mode to target small blood vessels under the skin, reducing congestion and improving skin tone uniformity. However, individuals with sensitive skin or prolonged redness often need longer treatment times than those with only simple telangiectasias. The course may extend to about 4-6 sessions or more, depending on the response.

Beyond laser treatment, patients should use gentle skincare products, prioritizing adequate daily moisturizing and sun protection. Avoid overusing unverified cosmetics or products that can cause irritation, as these factors may exacerbate skin redness and vascular dilation.

If numerous tiny blood vessels appear on the nose wings, cheeks, or if prolonged redness causes self-consciousness, patients should visit a hospital with a Dermatology - Aesthetic Dermatology department for examination and assessment of the lesion's extent. Choosing the correct technology, treatment parameters, and developing a suitable regimen helps effectively improve telangiectasias and limit the risk of recurrence.
