Tea tree oil is one of my favourites for clearing acne, being dubbed as "natures antiseptic". Studies have shown it is as effective as 5% benzoyl peroxide in controlling those nasty spots! It's also super cheap: available at supermarkets and drug stores from as little as £2.99 as an oil (Tesco, Superdrug, Boots), or if you're perhaps looking for something a little more portable and on the go there's the Tisserand Tea Tree+ Anti Blemish Stick at £4.50. The great news is, tea tree not only helps acne, but has multiple uses: curing athletes foot, head lice, viruses, and coughs, giving it holy grail status in my eyes.
Another at home remedy... baking soda really is the perfect exfoliant. The only thing also needed to help you get rid of that nasty dry skin is some water, and it becomes the perfect paste. I also find it leaves your skin feeling soft and nourished, unlike many others. Another fab property of baking soda is it's slightly bleaching. Now, I don't mean for people of colour trying to lighten their skin, I mean for people who have had poor skin and want to try and minimise the scaring... it really does work!
I also find that mixing orange juice and baking soda together to create a smooth paste (there's no real ratio, just trial and error) to place on your face as a mask is a great way to reduce sore cysts and hyperpigmentation.
Baking soda is also pretty cheap, starting at £1.49 in supermarkets, it'll be the most affordable scrub you've ever had!
If by any chance you don't have the others stocked in your cupboards, you will have this! All you need is a basin, a towel and boiled water. Placing your face over some hot water with a towel over the back, can do wonders to your pores: after they're open, go in with some tissue covering your nails, and get rid of your black heads with your nails. I don't know if people really realise what a transformation in your skin, once you have gotten rid of blocked pores, as there's generally a focus on whiteheads and cysts. It really can be amazing.
If you want an extra kick, add a drop of some tea tree oil for its antiseptic properties! Remember, get some ice or toner afterwards on those pores, otherwise they will become blocked again sooner.
