DESPERATE FOR SKIN ADVICE : suggestion?

I'm a teenager (17) with super oily skin, and I'm desperate for help! I've been dealing with:

• Pimples, nodules, and cysts on my forehead, hairline
• Dark spots and post acne hyperpigmentation
• Excessive oiliness

I'm on a tight budget (using my savings) and can't afford much expensive skincare.

Please help me with: - Affordable skincare product recommendations - Simple, effective routines - Home remedies - Tips for reducing oil production - Advice on preventing dark spots Details:

• Skin type: Oily
• Skin tone: Dark
• Current skincare routine: using acnestar (but it doesn't seem to work), used moisoft before then clean &clear , purchased acmed facewash today, and i was prescribed keraglo shampoo as i went for both skin and hair problem.. she wrote me follifast tincture and folli hair tablets for hairfall so my budget is really tight)
