@Cold_Cherry24 hrs after microneedling or the next day if you sleep on it you can do sunscreen.

Be very careful you have ethnic skin and we don't want to PIH or hyperpigment. Use tretinorin or differin / retin a at nights when your not healing from the microneedling, Hydroquinone is also a good treatment, you can do this a few weeks prior to microneedling.

Care for microneeding is not to put anything until the channels heal up. Pure ha serum is fine prior to microneedling. After do not exfoliate until your fully healed. You can use a Korean / Chinese Face mask with actives 24- hrs after if you wish. Other than that there is no aftercare other than healing.

How do I judge the healing of the micro-needle channel?

@Cold_Cherry24 hrs after needling they should be sealed up and products won't go to deeply into the skin. Aloe vera is very soothing and emu oil.

I have only Vaseline around me. Can I use Vaseline and Retinoic Acid alone?

@@Cold_CherryVaseline is fine if you wish but really nothing is needed with microneedling. You can use your mosturizer, sunscreen, sheet masks, retinoic acid all that 24-hrs after.

thanks for your advice
Retino-A are now used every night, hoping it will help produce collagen.
