Why do I have dry, itchy patch on eyelid?

This is a safe approach if you include orange peel paste in your skin care regime once per week. However, one must be aware that it could irritate or sensitize the skin in some cases. Be sure to do a patch test with the orange peel paste before using it along side salicylic acid cleanser and niacinamide serumand if any adverse reaction occurs, then stop its use.

I recommend that you see a dermatologist for this issue. The scar tissue that resulted from the surgery might have injured the hair follicles, thus depriving them of any regrowth. Unfortunately, there is no scientifically based treatment to re-grow hair in scar tissue except by means of a transplant. Some topical treatments may be prescribed by a dermatologist

The fine lines and dullness can occur due to the aging process and sun exposure. The under-eye bumps may be milia or small cysts. Dark circles can be caused by lack of sleep or genetics. Open pores are usually associated with oily skin. You can use gentle exfoliants, retinol creams, eye creams, and skin-tightening serums to help these issues. 

When certain allergies occur, body parts tend to swell. This might have been caused by contact with something like a plant or chemical that does not agree with you. Ensure the affected area is washed properly. To reduce the swelling, you can use an antihistamine. Seek immediate medical attention if things get worse or if you find it hard to breathe.

You might be dealing with a common issue called acne. The back can easily get acne due to things like friction from clothes, sweating, or clogged hair follicles. To treat these spots, keep the area clean and dry, wear loose clothing, and use over-the-counter acne treatments with benzoyl peroxide or salicylic acid.

Without a physical examination, it is difficult to understand your problem and the cause of it. I advise you to visit a dermatologist for proper diagnosis of your condition. Based on that, he may recommend the right treatment for your problem which can include antibiotic or anti-inflammatory creams.
