Sudden facial acne may be caused by excessive late nights or rest, poor sleep, overexertion, or large amounts of spicy and irritating foods, including raw onion, raw garlic, chili pepper, strong tea, etc. It may also be caused by large amounts of greasy diet and sweet foods. Before clinical treatment, the above mentioned triggers need to be avoided, while topical application of adapalene gel or retinoic acid ointment can be applied to combat keratinization of the hair follicle mouth. Oral medication can be applied with isotretinoin soft capsules or vincristine capsules and combined with Bacitracin Tagetes capsules. For physiotherapy, you can choose to treat with fire needle puncture, or with cosmetic needles to eliminate acne.
