It all depends on your skin type really, as everyone's skin is different. These are a few options and steps you could take...
1. Go to your gp - they offer a wide range of products specific to you; the contraceptive pill, creams, face wash etc.
2. Stick to a routine with your skincare, however, do not over complicate it - make sure to wash, tone and moisturise (even if you have oily skin, make sure to moisturise!!!)
3. Wash your face morning and night with warm water, and make sure to wash off all of the product, then use cold water (or even an ice cube to rub on your face) to make your skin feel smoother; this can minimize the small bumps and reduce inflammation.
4. You can also use natural remedies to target blemishes - tea tree oil, witch hazel are great.. apply these directly onto your spots as otherwise they can be extremely drying on the skin.
5. Minimize your use of makeup if you wear it. This is something I have found so hard, but it really makes the biggest difference for me.
Everyone is different, experiment a bit and I am sure you will find something that works for you! Hope this helps
