## Description

desertcart.com: Gelish Foundation Flex UV/LED Soak-Off Rubber Base Gel Nail – Light Pink, 15mL : Beauty & Personal Care

Review: Does it’s job exactly as expected - Would recommend - There’s absolutely nothing wrong with this flexible rubber base for gel nails. I bought this, because I had already been using a rubber base plus fiber glass to add strength to my fine brittle nails. Unfortunately, that other product was so difficult to remove. I figured getting one without fiberglass would make for easier removal, and I was right. This flexible base coat does provide more strength than plain gel polishes, but it’s not nearly as strong as the other rubber plus fiberglass product. This foundation flex performed well. I would recommend this brand if your nails aren’t as brittle as mine; the flexibility allows for some minor bending and easier removal. No weird texture. Suitable stickiness. Perfectly clear. Good product.
Review: Lovlier Than I Imagined - It was very easy to apply. It acted just like the normal foundation coat, but with the beautiful tint to it (I chose Nude), I didn't have to add color. I applied a coat, used the gel light, then applied the second coat. Then, I just applied clear top coat -gel light-(two coats for extra strength) and after a week my nails still look really nice. They havent broken at the "corners", chipped, or broken off. I do try to wear gloves or dishes and yard work, but I'm still kind of hard on my nails. I've been happily using all Gelish items for the ten years I've been doing my nails, and this is a step up for me for a foundation coat. I'm glad I got the larger bottle because this will be my go-to nail polish during the summer when I want a polished look but without the stronger color.

### ⭐⭐⭐⭐⭐ Easy to use, and looks beautiful on its own
*by R***N on February 27, 2026*

I love the ease of use and simplicity of this Foundation Flex because no additional base coat is required. There is no odor. The brush is small and straight, so I found it easier to work around the base and sidewalls of my nails without the need to use a liner brush to get in close enough. I flip my hand over just before putting it in the lamp to let gravity do its job. That ensures a nice level and balanced result. It was very easy to work with. I used two coats on my nails and after curing each layer in my nail lamp I wiped the inhibition (sticky residue) layer off the top with 99 percent ISO (Isopropyl alcohol) *because I was not topping it with another gel product, and then used one coat of regular lacquer topcoat. *NOTE*If you are doing a full gel manicure on top of the Foundation Flex coats, don't wipe the inhibition layer on the Foundation Flex. That layer serves as the surface for whatever gel you use on top of it. Once you complete your gel manicure you would only need to wipe the top coat layer if it isn't a non-wipe gel. Many gel top coats are non-wipe. Always read the product labels and directions. I bought the Light Pink and the Light Nude. Both are pink tones. The Light Pink is a cooler slightly deeper shade and it has a beautiful milky look after two coats. The Light Nude is a softer/lighter pink. Both colors look clean and natural. Both are perfect for French manicures. I included pictures of both products to help with color visualization. I love the finished look. I also love that I can use regular lacquer polishes over it when I want to change the color. As long as you use non acetone remover you can take the regular lacquer off and change it as much as you want. If you use full strength acetone it will slowly eat away at the product so that's obviously not a good idea. The finished products look really beautiful.
