Detailed answer

Spot treatments can be effective for treating acne on the chest and shoulders. These treatments usually contain ingredients like benzoyl peroxide, salicylic acid, or sulfur. They work by penetrating the skin to unclog pores, reduce inflammation, and kill acne-causing bacteria. When using spot treatments, it is important to follow the instructions and only apply the product directly on the affected areas. It is also recommended to avoid excessive use, as it can cause dryness or irritation. Additionally, spot treatments should be used in conjunction with a consistent skincare routine that includes gentle cleansing, exfoliation, and moisturizing to effectively manage and prevent acne.
