This one is pretty standard, but it needs to be said! Drink a large amount of water every single day, around 2-3 litres. Personally, I’m not the best at doing this and often don’t drink as much as I should, however I’m trying to improve and you really do see the benefits of doing this. Another thing is to eat healthily. I’m not saying you should have a salad for every meal, but have a balanced diet from all the different food groups: carbohydrates, protein, dairy, fruit and veg and fats and sugars.
Clean your makeup brushes. When you're repeatedly using the same makeup brush on your face it picks up bacteria and eventually starts affecting you. You wouldn't use a toothbrush again and again without using toothpaste and running it under the tap. It's the same with a makeup brush, you need to wash it regularly.
Invest in a good cleanser. There are a few things you need to consider when buying a cleanser. Whether you have dry skin, oily skin or combination skin. You can get a cleanser accordingly as there are oil free cleansers (Neutrogena does a good one) and extra moisturizing ones (Aveeno is a good brand for them). The cleanser that I use is the Biore blemish fighting ice cleanser. I feel it isn't for people with lots of blemishes but it does help prevent them and is great for skin with a few spots.
Moisturize! Even if your skin is oily, you still need to moisturize it. This is because if you don't your skin will compensate for that loss by producing to much oil, leading to more breakouts.
If all else fails, go to see your doctor. Your GP will be able to tell you if your face is fine, ok or if your spots are a serious problem. At the end of the appointment you may even be prescribed medical treatment for your spots which will hopefully clear them.
