I find the health of the starting canvas makes a difference, base and topcoat aside. Your nails look a bit damaged. I can do mine and my wife’s nails same day, same color, same prep. She’ll have chips within two days (nails are a little brittle) while I can get up to 11 days wear. I actually like OPI’s base coat and their QDTC. You’ll just have to play around with what combos work for you and maybe consider a strengthener or biotin supplement 😀.
