Some treatments for oily and acne-prone skin that you can do at home are: 1. Keep your skincare essentials at home such as tea tree oil, neem, aloe vera, etc. Do not apply garlic. It can cause burning sensations. 2. Go for Multani Mitti as an alternative to salicylic acid. 3. To reduce swelling, apply ice on your face. 4. Do not mix too many ingredients. Be careful while mixing it. Do not over-wash your face. It can remove the oil layer from your skin and make it dry and irritation may happen. At the same time, your face will start secreting more oil.
