Hya! Im recently qualified and using The Gel Bottle inc products- non wipe top coat. On the last two sets,ive noticed that ive had a couple of dull spots appear... any ideas? I wondered if the IPA hadn't dried before i applied top coat, altho on one set I hadn't used alcohol as only did a base and shiny top? Cured for 60 secs in Sun LED lamp. I dont want this happening on real clients as it does spoil the look of the nails! Thanks in advance!
