How to reduce redness and swelling on injured finger?

There are many treatment options available to help address your concerns. You can choose from a basic skincare routine to more involved treatments such as laser treatments, chemical peels, light therapy, micro-needling, and laser treatments for acne scarring. These will work by stimulating new collagen in your skin, which can help reduce the appearance of scars. You can look into chemical peels, laser treatments, and light therapies for hyperpigmentation and uneven skin tone. These treatments can help to break down pigmented cells and stimulate new cell growth, which in turn can help reduce the appearance of hyperpigmentation. For dullness, you can look into facial treatments such as microdermabrasion, which can help to exfoliate your skin and reduce dullness. Cost of these treatments can vary widely, depending on the type of treatment you choose. It is best to consult with a dermatologist to get better treatment options.

Cold sores result from the herpes simplex virus spread by close contact such as kissing or sharing eating utensils. Nonetheless, passing herpes through sharing food or drinks is very unlikely.
