NEVER take antibiotics for curing skin problems. Antibiotics make things worse. Also, skin products usually don’t work or just temporarily.
Acne and skin problems in general are a typical symptom of leaky gut syndrome (so, candida).
Do you have any other symptoms?
You could ask your doctor to do a stool or blood test.
In the meantime you can also try to eliminate all ‘suspicious’ food, which means only eating (raw) vegetables for a 3-4 days and see if your skin problems change. Since this is beneficial for everyone, you can try this anyway.
