Razređivači su važan pomoćnik svakoj lakoholičarki, ali i bilo kojoj drugoj korisnici lakova za nokte, a kod nas nisu dovoljno poznati kao vrsta proizvoda. Kao što im ime kaže, razređivači služe da razrede zgusnuti lak, bazu, nadlak. Oni nadomešćuju supstance koje su izvetrile i na taj način vraćaju svežinu laku. Za razređivanje ne treba koristiti aceton ili druge skidače laka jer je njihova funkcija razgrađivanje laka. Sigurno ste primetile ako ste koristile aceton ili skidač da razredite lak da je lak trenutno možda osvežen, ali kasnije da je u gorem stanju nego što je bio pre "razređivanja". Posebno ako skidač sadrži ulja. Zato nemojte to raditi. U zavisnosti od toga koliko vam se lak zgusnuo treba da dodate manje ili više razređivača, ali uvek je bolje dodavati malo po malo uz mućkanje u međuvremenu dok ne dostignete željenu gustinu laka. Na ovaj način je moguće ne samo u potpunosti iskoristiti lak, već možete oživeti onaj davno osušeni omiljeni lak koji čuvate jer ne možete da mu nađete zamenu.
Nail polish thinner is important helper to every polishaholic, but also to any other polish user, and at least in Serbia they aren't well known sort of product. As the name implies, nail polish thinners are used to thin out thickened polishes, base and top coats. They replace ingredients that have evaporated from polish and make it usable again. Acetone or other polish removers shouldn't be used for this purpose because they are used to break down polish. You may have noticed if you've put nail polish remover in nail polish that the polish may be more manageable at that moment, but later it becomes worse than it was. Especially if your remover contains oils. So don't do it. Depending on how thick your polish is, you should add more or less thinner into it, but it is always a good choice to start small, adding a few drops at a time and mixing in the meantime until you reach desired consistency. This way you can not only use up the polish, but you can revive that long dried up polish you love and keep because you can't find a dupe.
