How long have your scars been there, and roughly how deep do they go?
That's actually pretty important info, because depending on the type of scar, totally different approaches make sense. If they're more like indentations (atrophic scars), then building up collagen works well. But there are also raised scars or scars with pigmentation issues, where that won't necessarily get you anywhere.
What I think matters: a lot of people underestimate how long it actually takes and that you'll have pretty red/irritated skin for a while afterward. If you're still out and about noticeably in the summer (I'm out a lot right now), that gets uncomfortable. You really need solid UV protection afterward, otherwise you risk ending up with hyperpigmentation instead of improvement. That's why some people do these treatments more in fall/winter.
Besides microneedling, chemical peels or laser treatments in more serious cases could also be relevant - it really depends on the scar structure. Best thing is to have someone with actual expertise take a look, not just a beauty clinic that wants to sell you everything.

For about 15 years now, pretty shallow indents. Thanks for the detailed answer, especially about UV protection and timing during the year.
Microneedling really worked wonders in my friend group, especially when you do multiple sessions - it stimulates your body's own collagen production and flattens out the scars noticeably.
Depending on how deep the scars are, laser therapies (fractional laser) or chemical peels can help too, but honestly you should talk to a dermatologist about which method works best for your scars.
Using retinol as part of your daily routine helps as well, but that's more of a long-term thing and as support, not as a miracle cure.
What's important is being patient - acne scars from years ago won't disappear in a couple of weeks, but with the right treatments you'll see really noticeable improvements after a while.
Laser treatments like fractional CO2 or Erbium are often more effective than microneedling alone, especially for deeper scars - they actively destroy scar tissue and stimulate collagen production at the same time. But it takes longer to fully heal and it's more intense on your skin.
Something to keep in mind: with certain scar types (like hypertrophic, meaning raised scars), you might need something completely different like steroid injections or chemical peels. And honestly, with older scars the success rate tends to be better because the skin is more stable and responds better to treatment. Younger scars are sometimes still "active" and can confuse your skin even more.
Best thing is to get a consultation with a dermatologist - they can accurately assess what type of scar you have and give you realistic expectations. Nobody's going to magically make them disappear 100%, but "noticeably less visible" is definitely achievable with most approaches, especially if you do multiple sessions and stick with it.
