Hey, try applying tretinoin on lips, lactic acid 12% an hour before applying tretinoin.
This can be irritating, but it worked for me.
After doing this , if you can, then apply HQ 4%.
Strong sun protection on lips daily is a must while doing this

 

I dont think I can get hq 4%, will 2% work fine? Also whats the routine, do I apply hq at night and for how long ?

 

Do lemon lip scrubs at least twice a day. Tretinoin will be too strong but you can try it 1-2x a week. It will still make a difference.
The other tips mentioned by the user is also good. Just be careful. I'd leave more than an hour after lactic acid peel to apply tretinoin, maybe 3 days.
You can even incorporate vitamin C serum in the AM, this does help.

Yes vitamin C is very much helpful
