Here we can see a case where somebody needs a black gel lamp, and because usually it's the thumbnail that has this problem, If we don't have a lamp, we can replace it, if we don't have a lamp, we can replace it. It is very important that you always put the thumbs in the UV lamp separately, put the thumbs in separately one by one, Because if you put in 5 UV, the thumb turns outwards and the side LED's or UV tubes sometimes come up short, And it can't properly absorb those dark colors. Then, if we have taken this into account, or this into account, so that the thumbs are correctly inserted in the lamp, our lamp is strong, very important, If the lamp is not worn out, it is still possible that the material is thickly smeared. The most common problem with beginner gel varnishers is that they put too much material on the surface, and by avoiding so much pigment, they actually If the lamp is not replaced, we should replace the lamp, but if it is, we should replace it. Unfortunately, the top appears to be cured, so it looks solid, but still, after only a few days, such a huge chunk starts to break out of the guest's nail. Well, that's why it happens, so if the guest comes back, then unfortunately we have to file it down or we have to remove it, and start again with the whole mitre joint, maybe keep the base and then apply a thin coat of black like this again, Two copper lamps can then be covered with a cover material, and it is very important to make sure that the lamp is well covered, don't just put it on the front of the UV lamp, put it full depth and use a strong lamp. It's important to always check your lamp, so if there's any kind of wrinkling or cracking, anything like that, then always check the UV lamps. If we know that we have been using it for a very long time, then it is worth replacing the tubes in it, or the whole lamp is worth replacing. In the case of LED lamps, let's see if the LEDs are not burnt out or if they are still under warranty, If there is no warranty, then get it fixed, if not, then just replace the lamp again.
