First off I'll say definitely try what chado said. No need to do more than necessary, and it's good to start with a baseline to see how your skin does naturally.
If that doesn't improve, feel free to try out what I did. I struggled with acne for ages and ages, now I very rarely have acne. So here are all the things that have worked for me personally:
1. Never ever ever touching my face - Even now, if I touch my face I can more or less guarantee I'll have a zit there the next day. I'm pretty sure this is from the oil on fingertips.
2. Eating well/keeping stress to a minimum - If I eat like absolute shit one day (especially oily foods), I sometimes have a zit the next day. Same goes for if I had a ridiculously stressful day and didn't take time to calm myself down.
3. Go to a store for skin care or the skin care section of any department store. (I went to The Body Shop since my friend worked there.) Talk with the employees working there about your skin type (oily/dry/combination/etc.) Start using cleanser, toner, moisterizer they recommend for your skin type (I use the Seaweed product line, which is for oily/combination skin). And FYI, it took my skin a few days to adjust to this - got a little worse before it got better.
4. Use Benzoyl Peroxide. This has definitely helped me the most. I use this (https://www.cvs.com/shop/cvs-health-acne-treatment-gel-1-oz-prodid-1015802). And again, it took my skin a few days to adjust to this. Once it did and I started using this consistently, my skin really cleared up.
5. Use one of those products if you've been sweating. I usually use the cleanser/toner/moisterizer every morning in the shower, then the benzoyl peroxide RIGHT after a workout. Or if I haven't worked out but my face feels a little oily, I'll just give it a wash before bed.
6. If you still have acne issues after this, see a dermatologist. They'll know best and will be able to recommend next steps. I believe the last thing they'll recommend is accutane (which is the nuclear option, but supposedly it works great).
Keep in mind that most likely you'll always get acne from time to time. I still get a zit every month or so, but they're rare and gone quick.
And as a last note, try working out more. I'm not 100% about this, but once I started working out consistently and getting into good shape it seemed like acne became less common (as long as I washed my face ASAP after I was sweating).
