So I used retinA for the last 2 years now acne is very minimal and sporadic. started to use triluma combined with retin A .1 in Sept 2017 and heard that triluma is only supposed to be used for 2 months? i have been using about 5 nights/week for the last 4 months. My nose gets red if I pinch it im Black with relatively dark skin so im concerned this red nose thing is a sign of thinning skin I am not sure what the long term effects of either cream is so im a bit concerned
