This is the base gel I copied from the salon!! It's famous, right? Gisele haha. Whenever I do it myself, the durability is always so poor, so I was trying to figure out why. The salon told me that the base is much more important than I thought and recommended this one, so I bought it. It definitely lasts longer than regular base gel. However, even though I bought it, doing my nails myself is such a difficult task for someone with clumsy hands like me, so I'm still going to the salon lol. I'm so jealous of people who are good at doing their nails themselves. I realized just how much more convenient it is to go to a salon... Long live capitalism...
