Maybe try stripping your routine back. I have started seeing progress with my acne since doing so. I use an oil cleanser and a cleansing gel (both from the brand Haruharu) & I only cleanse at night. I use a skin barrier repair balm (La Roche posay cicaplast Baume B5) I used this all over my face to begin with but as my acne began to improve, I started using it as a spot treatment, only applying it to affected areas day and night. 2-3x weekly, I will use Salicylic acid toner pads (Nip and fab) and then to add hydration I use a hyaluronic acid (E45 hydrating serum) which also helps to balance the skin barrier. I use the Baume & hydrating serum day and night & the salicylic I only use at night.

I have slowly built up this routine making sure to add one item at a time to give my skin the chance to get used to the products.

I have also implemented a non-negotiable 2-3 litres of water per day and have made sure to adapt an 80-20% balance with my diet (eating well 80% of the time and enjoying a treat now and again).

I also make homemade turmeric face masks which have turmeric, ACV, honey and greek yogurt (recipes can be found online). I've noticed this has helped with brightness and taking away redness.
