How do you remove moles?
Common Mole Removal Methods:
Surgical Excision – The doctor numbs the area, cuts out the mole with a scalpel, and stitches the skin. Best for larger or deeper moles.
Shave Removal – The doctor numbs the area and shaves off the mole with a surgical blade. No stitches needed. Best for raised moles.
Laser Removal – A laser light targets the mole and breaks it down. Best for small, flat, and pigmented moles.
Cryotherapy (Freezing) – Liquid nitrogen freezes the mole, causing it to fall off. Best for small, non-cancerous moles.
Which Method is Best?
If the mole is suspicious or changing, doctors prefer excision for lab testing.
If the mole is small and harmless, laser or shaving may be used.
For safe mole removal and expert advice, visit Irvine Skin.

Which method is best for facial hair removal?
Best Hair Removal Methods:
Laser Hair Removal – Reduces hair growth over time. Works best on dark hair and light skin but newer lasers work for all skin tones. Takes multiple sessions.

Waxing – Removes hair from the root and lasts 3-4 weeks. Can be painful and may irritate sensitive skin.
Threading – Great for shaping eyebrows and removing upper lip hair. More precise than waxing but may cause slight discomfort.
Hair Removal Creams – Quick and painless, but some people may get skin irritation.
Which One is Best?
For permanent results: Laser
For smooth skin: Dermaplaning
For shaping eyebrows or upper lip: Threading

Potential effects of unknowingly long term contact with allergen?
Possible Effects of Long-Term Allergen Exposure:
Skin Reactions – Redness, itching, scaling, or rashes (as seen on your legs).
Respiratory Issues – Throat tightness, irritation, difficulty breathing, or a choking sensation.
Neurological Symptoms – Lightheadedness or headaches due to immune response.
Could Polyester Be the Cause?
If you have a sensitivity to polyester, wearing it regularly may be triggering chronic low-level inflammation, leading to throat swelling. While rare, textile allergies can cause more than just skin irritation—especially if fibers break down over time, releasing chemicals or particles that trigger an immune response.
What You Can Do:
Eliminate Polyester – Switch to 100% cotton clothing, bedsheets, and underwear for a few weeks and see if symptoms improve.
Patch Test at Home – Wear polyester fabric on a small patch of skin for a day and check for reactions.
Try an Antihistamine – If your symptoms improve with antihistamines, it could indicate an allergic response.
Keep Pushing for Testing – A dermatologist or allergist may help confirm the allergy with patch testing.
Since appointments take time, avoiding polyester in the meantime is a smart move. If symptoms persist or worsen, consider seeing an ENT or allergist to rule out other possible causes.

Are these stretch marks?
Stretch marks (striae) are usually painless, thin, and don’t blister.
Blistering and pain suggest something else, like:
Skin irritation or allergy (reaction to workouts, sweat, or skincare products).
Skin infection (if the blisters fill with fluid, pop, or get worse).
Blood vessel issues (since birth control can sometimes affect circulation).
Erythema ab igne (if you’ve used heating pads or hot showers often).
Rare conditions like connective tissue disorders (less likely but possible).
What you can do:
Avoid scratching or rubbing the area.
Keep the skin clean and dry to prevent infection.
Stop using cocoa butter & vitamin E (some people react to them).
Try a mild moisturizer like aloe vera or fragrance-free lotion.
See a doctor or dermatologist if blisters spread, become painful, or don’t heal.
Since the marks on your right leg improved but left leg worsened, a doctor can check for infections, allergies, or other skin conditions.

Rash on legs?
Liver-related skin problems – Cirrhosis can cause red spots, rashes, or tiny blood vessels showing on the skin.
Swelling in the legs – This can make the skin irritated and itchy.
Poor blood flow – The liver helps with circulation, and when it’s damaged, the skin can react.
Infection – Cirrhosis weakens the immune system, so infections are more likely.
Allergy – It could be a reaction to medicines, food, or something touching the skin.
What to do:
Moisturize the skin to stop dryness and itching.
Don’t scratch to avoid infection.
Check for infection (warm, painful, pus-filled rash).
See a doctor soon if the rash gets worse, spreads, or if he has swelling, yellow skin, or confusion (these could be serious).
