Acne is a horrible soul destroying condition and the even more horrific truth is, THERE IS NO REAL CURE! You can try everything, spend your hard earned on products, consult with dermatologists, but your acne stays. Certainly acne is treatable, but you can never totally cure it.
Does this mean that you should just leave it well alone. No, of course not, acne is treatable and can be improved but it's also important to be aware of the fact that stressing out over your acne will only make the situation even worse.
Diet is a very important factor in improving your acne. Fruits, vegetables, fish and chicken are great for your skin and acne. A balanced diet not only helps you stay toned and fresh looking, it also sharpens your mental abilities and is great for your skin.
Shop around for products but don't fall for every product that's released. Different products have varied results on people and skin types. Make sure you purchase non oil based products so your pores can breath and remove dirt etc.
Be sure to use only non oil based products as the oil based products are terrible for clogging up your pores and not allowing your skin to breath.
Being a non-oil based product is a big selling point for vendors so you should have no problems finding non-oil based acne products.
When you have persistent acne, avoid trying to treat it yourself. Since acne is complicated, getting advice and treatment from a dermatologist is recommended.
There are tons of great treatments available. Some such as laser treatment are very expensive. So at least by visiting a dermatologist you will know whether its worth shelling out your hard earned on some advanced treatments.
