The raised capillaries on the hands may indicate a condition known as telangiectasia?

Hello, Dr.
Jiang.
I would like to ask why the pores on my hands are protruding, resembling chicken skin, about the size of a one-dollar coin.
There are about four or five pores that are raised, and this started after I returned from Kenting (after swimming/sunbathing).
Even when I scratched the raised pores, they would break the skin, and I've noticed this phenomenon only occurs in areas exposed to sunlight (on my arms).
It's very bothersome and unsightly.
What could be the cause of this? Previously, this only happened in winter, but it has been occurring for the past few days, and it's quite troubling.

If your skin is itchy, applying topical medication will quickly improve the condition.

More Info

The raised and bumpy appearance of your hand pores after sun exposure could be attributed to a few different factors, primarily related to skin reactions to UV radiation and environmental conditions. This phenomenon, often described as "chicken skin" or keratosis pilaris, can be exacerbated by sun exposure, especially if your skin is sensitive or has been previously damaged.

Possible Causes:
1. Keratosis Pilaris: This is a common skin condition characterized by small, raised bumps, often resembling goosebumps. It occurs when keratin, a protein in the skin, builds up and clogs hair follicles. Sun exposure can sometimes make these bumps more noticeable, particularly if the skin is dry or irritated.

2. Sunburn or UV Reaction: After sun exposure, your skin may react by becoming inflamed or irritated, leading to a raised texture. This is especially true if you have not adequately protected your skin with sunscreen. The UV rays can cause the skin to swell slightly, making pores appear more prominent.

3. Heat Rash: If you were in a hot environment or engaged in activities like swimming, you might have developed a heat rash. This condition occurs when sweat ducts become blocked, leading to small, raised bumps on the skin.

4. Allergic Reaction: Sometimes, exposure to certain substances while in the sun, such as lotions, sunscreens, or even chlorinated water from swimming pools, can cause an allergic reaction that manifests as raised bumps on the skin.

Recommendations:
1. Sun Protection: Always apply a broad-spectrum sunscreen with an SPF of at least 30 before sun exposure, even on cloudy days. Reapply every two hours, especially after swimming or sweating.

2. Moisturize: Use a good moisturizer after sun exposure to help soothe the skin and prevent dryness, which can exacerbate conditions like keratosis pilaris.

3. Gentle Exfoliation: Consider using a gentle exfoliating scrub or a product containing alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs) to help remove dead skin cells and prevent clogged pores.

4. Hydration: Keep your skin hydrated by drinking plenty of water and using hydrating lotions or creams.

5. Avoid Irritants: If you suspect that certain products are causing irritation, try to avoid them and see if your skin improves.

6. Consult a Dermatologist: If the condition persists or worsens, it would be wise to consult a dermatologist. They can provide a proper diagnosis and recommend treatments, which may include topical retinoids or other medications to help manage the condition.

Conclusion:
The raised and bumpy appearance of your pores after sun exposure is likely a reaction to environmental factors, including UV radiation and potential irritants. By taking preventive measures and caring for your skin, you can help minimize these effects. If the issue continues or causes you concern, seeking professional advice from a dermatologist is always a good step to ensure your skin health.
