The Gel Bottle not curing properly

TGB recommend thick coats of application. I'm using SUNUV4 48 UV LED Lamp
Omg!! I think it could be the LAMP!! I have this exact lamp and I just cannot get it to cure! Even when I cute for 2 mins also when I put the top coat on, colour from the gel I have just applied comes on my topcoat brush!

BUT I bought a Mylee lamp at the Beautyshow last week and it’s fab! Was only £30 compared to £65 for my SunUV and it CURES
 
I agree 100 per cent. Every company tell you to use there lamp. Nail products cost us technicians tons already. Most of us are small business they are self employed and work mobile or from home and do not have 100s of pounds to spend on a lamp. But I don’t see nothing wrong in anyone using these lamps like myself.

Lou,
I understand why you and many others say this, but you don't have the knowledge to make an informed decision:

Some scientists in the USA visited nail salons, and did some measurements on their UV lamps. Most of these were the traditional 9W bulb based lamps, but the principle is the same for LED-UV lamps. The numbers on top of the bars are the Watts/number of bulbs. Notice most of these are 36W lamps.

The diagram shows the amount of UV Illuminance (like brightness) measured in 5 different positions in each lamp. So when you look at a bar, the top is the brightest position and the bottom is the least bright. The bigger the bar - the more different in maximum and minimum brightness.

Less imagine that a gel requires an UB Illuminance of 10 mW/cm3 to cure correctly. Which UV lamps would do this? UV lamps 3, 6, 9, 12 are all below this line! But UV lamps 1, 3 4, 5, 13, 14, 15, 16, 17 - will only provide a correct cure at the brightest positions in these lamps. At other positions they will under cure. Only lamps 7, 8 and 11 are bright enough in every position.

Remember, under curing not only means less reliable nails, it also produces under cured gel dust that causes allergies. And it the smallest invisible dust that floats in the air, that can land on any exposed skin - which is why people get reactions under their eyes and on their neck. E-files produce a lot of this micro dust.

Now as far as these nail salons are concerned, they think their UV lamps "work" because the gel / GP becomes hard. But gels become hard enough to file when only cured 50%. So it is impossible for know if a UV lamp correctly cures a gel, unless it is tested in a scientific laboratory. How many brands that simply buy product from factories and slap on labels, understand this or have access to a scientific lab and a chemist....?

Why is it that very few nail schools teach this critical safety information?

What all of this means is that the UV lamp has to be matched to the gels, or the gels matched to the UV lamp. This process of testing and matching is time consuming and expensive - this is why serious companies only sell one UV lamp.

I'm a manufacturer, so I can understand if some people (who don't know me), doubt what I say. So here is a link to an article published in Scratch.

Here is what the President of the British Society of Cutaneous Allergies had to say:

“The lamps provided with kits are very specific to the individual gel-polish system, so when they buy polishes from different systems the lamps don’t work as well and they’re at much greater risk.”

I.e. UV lamps and gels must be matched.

I am a nail technician not a scientist. Company’s need to change less then so that small home business can afford to buy the lamp. I myself have never had any trouble with any products with my lamps.
 
Whoever told you that is talking nonsense, sorry. Either they are being deliberately dishonest to sell their gels to anyone regardless of the UV lamps they use or they don't understand basic gel chemistry and never properly tested their products. Using the incorrect UV lamp is the#1 cause of nail product allergies according to the British Association of Dermatologists.

Hello
Itis not the brand of the lamp what matters. It is its wattage. 48 is the most powerful. If only one client has come back, something is odd with her. I do wipe also underneath. I would do on this client, fast underneath cure of 15 seconds.

The more watts the better.
 
I guess we have different parameters as to what constitutes a professional brand.

Sun Uv pride themselves on being the market leader on aliexpress. Their focus is quantity and they are not aiming for the professional market. They manufacture an economy line of consumer lamps which, to me, have no place in a salon.

Yes, they also manufacture for others. So do bluesky.
Funny this because the gel bottles lamp is actually sun uv
