Should I continue using retinol A & a brightening complex, even if this irritates my skin & I ended up with more dark spots?

I started using a brightening complex twice daily & retinol A 0.5% 2xper week for dark spots & melasma 3 months ago. I have very sensitive skin & maybe rosacea. I would get the redness on my nose & cheeks & rashes on my face. I ended up with more dark spots, the previous dark spots darker, rough skin & flaking. Should I continue or stop? I still do not see any positive results, except the redness, bumps & more dark areas on my face & bluish dark area on my forehead !
