A set of professionally operated nail polish can usually last for 2 to 3 weeks, during which there will be no obvious collapse or peeling. The actual maintenance time of many DIY players is often only 7 to 10 days. The gap depends on these hard indicators: whether the early cleaning is fine enough, the power of UV/LED lamp is stable, and your brushing method. To solve the problem of premature “rollover” of nail polish, you must completely remove dead skin on the nail surface, take away excess grease with balancing liquid or primer, and remember that whether it is primer or sealing layer, you must “wrap” your fingertips “. As long as you strictly implement these steps and ensure that each layer of thin paint is thoroughly dried, DIY manicure can completely reach the “gold standard” of 21 days, and the effect is definitely not lost to professional salons.

Salon Class vs. Home DIY

The gap between professional stores and home operations is often due to environmental and product details. The reason why salon manicures are stronger is that the manicurist will deal with the tiny details that are difficult to see with the naked eye, thus preventing the nail polish from sticking up. If you find that your DIY manicure starts to fall off in less than a week, it is usually not the quality of the glue itself. Most of it has fallen into the pit of the “long-term pillar” I will talk about next.

Pillar 1: Meticulous Pre-Treatment

Nail polish requires a completely clean, dry and oil-free surface to bond tightly to the real nail.

• Dead skin cleaning: Any nail polish that sticks to the skin or covers the dead skin will sooner or later become warped as the nail grows. You have to use a push stick or dead skin softener to completely remove the invisible “dermis” on the surface of the nail to ensure that the glue is only caught on the hard deck.
• Dehydration and primer: Natural oils are the natural enemies of nail polish adhesive. It is essential to use professional-grade dehydrating agents or pH-balancing primers, which absorb moisture and grease, create a slightly sticky surface and lock the primer in place.

Pillar 2: The Key Role Of UV/LED Lamp Power

Everyone should understand that the light is a chemical reaction process, not a simple “drying”. How long the nail polish can last depends directly on the degree of polymerization of the molecules. It is important to ensure sufficient lighting time:

Many DIY players are prone to make the mistake of using small lamps with extremely low power. The result is only that the surface is “fake dry” and the bottom layer is actually soft. Be sure to check the wattage of your lamps and strictly abide by the time recommended by the manufacturer-LED lights usually take 30-60 seconds, UV lights take 2 minutes, and each layer must be illuminated for enough time.

Pillar 3: Professional Grade Brushing Technique

The way you apply glue determines whether your manicure can only last 10 days or 21 days.

• Thin coating is the king’s way: too thick coating will lead to opaque, but also easy to shrink glue. I ‘d rather have you brush three layers of color glue as thin as cicada wings than challenge two layers of thick glue.
• Fingertip edging: This may be the most central step to prevent collapse. When brushing the primer, color glue and sealing layer, be sure to use the brush head to gently sweep the front end of the nail (ie, the leading edge). This step is like sealing the nail with a layer of film, which can effectively prevent moisture and debris from drilling into the adhesive layer.

Why Does My Polish Always Get Warped Early?

If your manicure lasted less than three weeks, there is a high probability of early peeling. This usually means that the bond between the nail surface and the glue layer is broken. In addition to operating steps, some external factors cannot be ignored, such as frequent soaking in hot water, or habitually using nails as tools such as “can openers”, which will destroy the edge. As long as you stick to the principle of “fingertip edging” and put the preliminary treatment in place, you will basically block most of the possibilities of failure.
