And I just want to clarify what I and many others have said several times that all of these products are only as good as the base they are applied to.
A nail in good condition does not need buffing for any of them if the application is accurate. A nail that does not have a good surface may need a light buffing for ALL the different brands, even Shellac! Eg a nail that has delamination will not successfully hold on to anything.
You need to use your skills and knowledge and do what is right for each client and each nail. I don't know why light buffing is such an issue! No one worries about glossing a natural nail!
Don't buff if you don't need to and save time. If the surface is not good then give it a light buff.
