I had a small papule / cyst on my upper lip line that was excised (without my permission, but that's beside the point here). This happened one month ago. The first picture shows the current scar. The second picture was taken on the day of excision. The third picture shows what the papule / cyst looked like before the excision.
Now, I have an oval-shaped indented surgical scar that is ~0.5cm wide in diameter.
I have dry, East Asian skin. Are there any products / ingredients that I should try? So far, I have alternated between exfoliating acids and tretinoin, and I religiously apply sunscreen. I'm not sure if silicone sheets / gels work for indented scars?
I have been researching growth factors like the ingredients in SkinMedica TNS Advanced+ Serum, for example. Growth factors seem controversial (could trigger cancerous growth). Has anyone used growth factors for indented scars successfully?
I've also been considering Non-Ablative Fractional Lasers as a potential treatment. Is this recommended? I'm not sure if lasers will cause pigmentation issues for my skin type, which is a Type 3-4 on the Fitzpatrick scale.
Thanks for reading! Any tips or suggestions would be much appreciated 
I'd say don't waste your money on topicals. They don't do much at all. Omega-3s, like 5-6 fish oil pills per day, helps with healing, but you're already a month out, so I don't think much of anything is going to make a big difference at this point.
I agree to wait a few months and then you can see what a scar revision specialist can do for you at that point.
Non-ablative lasers probably won't cause problems by the way. They're, well, non-ablative, so they don't affect the skin strongly. You could always try that now and see if it helps. If you get hyperpigmentation easily, ask questions and be careful no matter what you do though.
Keep us posted.
