Awesome product for strength and shine!
Attached is a pic of the mail hardener that I applied over Cherry 🍒 Cola Nail Veil. I’m sold! My nails aren’t splitting like they used to.

Great-looking protection for nails
Given my allergies generally to nail polish, I have to be careful about using it or my eyes can swell up like two golf balls. I’ve been very happy with this 2-in-1 product. No problems at all with my allergies. It’s 21+ free (doesn’t have 21 ingredients considered toxic, including formaldehyde, gluten, sulfates, and parabens). Also, my nails are less likely to chip and break when I’ve wearing it. In addition to using it as a basecoat I’ve begun to also wear it by itself. It has a wonderful sheen and protects my nails at times when I don’t want to wear a color. The product has antioxidants and vitamins intended to strengthen and enhance the healthiness of nails. Not essential, but plus for me: the maker of this product, Londontown, is a women-owned, family business that’s based in the U.S. (it started overseas). It professes a strong commitment to making its products as healthy and safe as possible. I’m giving it 4 stars rather than 5 because I wish it were a little less expensive. But other than price, it’s a 5 star product.

Really to early to tell but I’m optimistic!
My polish seems to be staying on longer, so hopefully something is happening behind the scenes!

Great product, best I have used!
This is the only base coat I will use. My nails are generally soft, so I need the hardener. It makes a big difference, and I highly recommend.
