Detailed answer

Spot treatments can be effective in targeting specific acne or blemishes, but they may also have some potential side effects. Some common side effects include skin dryness, redness, and irritation. This can be due to the active ingredients in the spot treatment, such as benzoyl peroxide or salicylic acid, which can be harsh on the skin and cause sensitivity. It is important to follow the instructions carefully and use spot treatments in moderation. If you experience any severe or persistent side effects, it is recommended to discontinue use and consult with a skincare professional.
