Your skin seems to be in very good condition and has no problems apart from the scars.
This routine is targeted to acne scars.
.5mm dermaroller - roll twice or three times a week.
1.5mm dermastamp - stamp densely every three weeks.
TriReduction Copper Peptides by Skin biology - you can apply it after rolling with a 0.5 mm roller, however first start applying it without dermarolling. The skin has to get used to it. Do not apply it on the same days as vit. C.
Glycolic 70% Acid Peel – it exfoliates the skin. Dermarolling with a 0.5 mm roller is more than enough to exfoliate. Using the A-Ret is also more than enough. Using yet another exfoliation is excessive.
Skin Eraser Cream (30% Glycolic + Lactic + Ascorbic + Other Ingredients) by ZenMed – the same as above.
100% Emu Oil - if your skin likes Emu Oil, apply a little after rolling with a 0.5 mm dermaroller but let other substances/creams penetrate the skin first (in case you use any).
Hyaluronic Acid - you can apply it after dermarolling with a 0.5 mm roller. It is not going to improve scars though. You seem to be young; you have enough of your own hyaluronic acid.
Vitamin C Powder and bottle to make you own serum – apply for three consecutive days prior to stamping. For the rest, apply twice or three times a week. Once a week you can apply it right after rolling with a 0.5 mm but only if it doesn’t irritate your skin too much.
Infadolan - apply a little after using a 1.5 mm dermastamp. If it doesn’t make you break out, apply a little for several more days after stamping.
Retin-A 0.05% Cream – in your case, apply only twice a week. Apply without dermarolling.
Clean & Clear 3-in-1 Exfoliating Cleanser (5% Benzoyl Peroxide) - apply only if you have acne. Apply without dermarolling. Do not apply two days after stamping.
Clean & Clear Dual Action Moisturizer (2% Salicylic Acid) - apply if you have acne or blackheads/whiteheads. Apply without dermarolling.
To make it easy and doable for you, apply Copper peptides twice a week, vit. C twice a week and Tretinoin twice a week.
BTW, you may be interested in the method of "hair replication":

I hope you are not angry with me or offended, When I saw the nice shape of your head I just thought this method would look really good on you.
This highly talented tattoo artist specializes in creating a very realistic "recently shaven head" look. (The technical term is "hair replication"). I have nothing to do with them, I do not know them. I think it looks good.
For anybody interested: Do not have this done by just anybody. It can end up looking terrible if they are inexperienced in making the dots look natural or use unsuitable ink and/or methods.
