Help me: Neck posture, hair, skin

[zxsKHHV]

I don't really like the area of my forehead. In my last post, some people recommended that I let my hair grow out to get dreads/locs, what would be the best haircut to let it grow out? Currently I get a low taper fade, but I think my barber isn't that good, so I'm going to use a beanie and let it grow for a while without cutting it until I find a better one. I have quite a lot of acne and my skin looks kind of saggy for someone my age, and then people also told me to use 0.025% tretinoin, which can help with acne, but what is the way to use it? How many times a week? The posture of my neck is also terrible, how do I fix this and give it a better appearance? If you can answer my questions I'd really appreciate it, thank you very much.View attachment IMG_20260808_142935.jpgView attachment rn_image_picker_lib_temp_6b39aa0e-19ab-4641-ab2f-c4e9657afacc.jpg
