So this idea of AFTERCARE came up in another thread. And thanks to @beautifulambition and others for the encouragement to start this thread. Anyway, there appears to be a lot of posters in recent months who have confessed to getting their scars sliced (subcision), poked (microneedling), zapped (laser), or poked and zapped (Infini) as well as burned (all things acid). There's endless debate about what treatment is considered optimal for what types of scar. However, there's not enough dialogue about what should be done after you get these treatments. Here, I'm not talking about staying out of the sun and other silly advices. For those, you can read elsewhere on the web. No, I'm more interested in the healing process, like "what stuff" is good (eg. useful)--not only to speed up recovery but actually help enhance the stimulation of collagen? After all, collagen remodeling is what we are seeking (dude, like what?).
You're welcome to get down and dirty, and dole out any sage advice on what you think others are missing out on. Just don't make us any dumber than we already are. 
** I will edit my posting here at a latter time as this is a rather large subject. 90% of healing is how your body heals which is uncontrollable, the rest deals with infection, nutrition, stress, and giving the body proper time to heal (not rushing it).
This is from the FAQ to start:
Q: Is there anything I can do to optimize my healing responses following invasive scar procedures?
A: Yes. Through a healthy diet (no sugar, processed carbs - corn, wheat rice, bread, pasta, candy and cakes, highly processed foods, lots of fruit, veggies, and greens, lean fat meats, low salt).
Topicals: Biafine (has aspirin a anti- inflammatory) or Vaseline - keep it moist until scabs fall off, don't pick it, vinegar soaks with diluted vinegar water, Vitamin K /Arnica Montana for the bruising and red, sunscreen all the time, hydroquinone (can be used for 2 weeks to deal with red) for bleaching and hyperpigmentation issues. Do not take blood thinning products (i.e. Ibuprofen / Motrin...take Tylenol instead, vitamin E).
Spices that thin the blood: cayenne pepper, onion, ginger, paprika, peppermint, thyme, cinnamon, dill, oregano, turmeric, garlic, chocolate, fish oil. ginkgo biloba, ginseng, magnesium, taurine energy drinks. You may take these once your body has healed from the initial surgery (a few days , to a week).
Makeup: can cause infection if the skin is not healed fully.
Drinking, smoking, and sugar hinder healing.
Make sure to get plenty of rest during recovery, & drink lots of water.
Supplementation: collagen/Gelatin, vitamin c, Bromelain (pineapple), pure HA serum.
Anti-inflammatory (supplements, foods) are your friends, they help the body heal quicker. Green tea, Vitamin K makes bruises go away, Vitamin C
Laser: keep the skin moist, use vinegar (white) to pat the area daily and reapply biafine, or Aquaphor, or Vaseline. Do not touch your face, and change the pillow daily (use a towel).
Filler: ice / ice / ice to get swelling to go down, take a antihistamine like Benadryl. Do not do any physical activities (like the gym) for 24- hrs after, do not drink 24 hrs afterwards, and do not have your teeth cleaned or worked on for a week before and after filler, released bacteria can be attracted to the filler in the blood stream. No makeup for 24 -hrs. Don't sleep on your face (where filler is) or push the filler out of where it was placed for 24 to 48 hrs.

Q: Can Guys Do Anything to Cover Their spots and Help with Self Esteem?
A: Guys you can be as manly as you want and wear makeup (the ladies have had this tool for some time).
Hear me out. Movie stars, news anchors, models, musicians, Youtubers, and even politicians wear makeup. Buy a concealer for just your acne scars and spots (spot treat them). You want it to match exactly your skin color and not be shiny ("matte"). My favorite is sold at Sephora (they color match you) Makeup Forever Camouflage Concealer, this looks extremely natural on the spots. Dermablend is sold at Macy's and Nordstrom. This is used for medical scars and to cover tattoos (they match your color) and it's very thickly pigmented. Ben Nye Cover All Wheel and Bill Nye Concealer Wheel sold on Amazon and Ebay (it has various shades), this is used in the theater.
You can wear Benefit Porefessional With or Without Makeup (Guys and Girls):
It's a blurring and pore filling cream

Okay, I believe the first sane question that should come to mind for those who just had their face treated is whether they should moisturize their face or not. If yes, for how long? I think the following thread (damn, it was written eons ago but still a good one) will serve as a good pointer for the newbies in that regard.
A Word On Tca Cross Post-Care: Dry Scab Versus Wet Wound
I just wanted to start a topic that can definitively answer a common question people have about TCA Cross: Should I let the wound scab or keep it moist? I've seen arguments on the board for both sides, but after trying both ways, I can pretty confidently say that moist healing is the way to go....
Here's one that has recently been discovered: make sure that you do your treatments during the daytime (8am - 8pm) and not at night. Wounds heal better and faster when they occur during the day as opposed to during the evening or night, and the difference is significant. They heal up to twice (!) as fast.
Here's a link to the abstract: http://stm.sciencemag.org/content/9/415/eaal2774
And here it is explained in an article: https://www.newscientist.com/article/2152754-daytime-injuries-heal-twice-as-fast-as-wounds-sustained-at-night/
1. Depends on the technique used. NOKOR vs traditional vs PRP vs filler vs multi-level Cannular vs Multi level Cannular with saline or PRP or with Cannular vs autologous blood, vs RF subcision with or without HAs or NS. Plus your history- do you keep reattaching, vs the thickness of your dermis and amount of scarring. Prevention of infection plays a HUGE ROLE, additionally any adjunctive procedures- microneedling, RF, CO2, NA laser, ....diet plays an important role- nutrients for collagen remodelling. Many other variables. Your specialist will guide you. 2 major issues, others just minor 1. Don't get a haematoma 2. Don't get an infection. Everything else can be easily sorted. If you do get side effects, good specialist will sort out asap to reduce fibrosis and reattachments- lumps. The later should NEVER be an issue if treated correctly.
