Nail Optimizer, Extra Strong Strengthener Base Coat for Weak and Damaged Nails, Nail Growth & Prevents Nails from Peeling, Stops Slipts, Chips & Strengthens, 0.5 oz

Item arrived when expected. Trying it out for the first time. I like that it doesn't have any harsh smells. The package does say it contains formaldehyde - not sure how I feel about that as it is a cancer, causing agent. I'm hoping the amount is so little, but I'm still on the fence about that.

Works great

.

My nails peel, so too early to tell if it works yet. I'm hopeful!

I've used this for a few days and it works great!!!! My nails are not breaking for the first time in my life!!!!

I’ve been using this for three months now. My nails are still bendable/pliable and still break easily. But can’t give a full review until 6 months of use, when my nails have fully grown out.The first month, I used it exactly as the directions said, then started using it as my first coat under nail polish (this, then base, 2 coats of color and a top coat). My nails haven’t grown any faster then normal and, like I said, don’t seem any stronger.However, I still think it has its uses.So, how is it useful? It dries really fast, so I use it every other day over my polish to keep the tips from fading or the polish from chipping. I can put it on and know that it will be fully dry in less then ten minutes.Also, used it everyday for a month, then every other day for the last two months (again, not for nail strength, but to protect my polish) and I still have half a bottle, so it lasts a while.I wouldn’t use it alone as a base coat though. It is rather thin (hence why it dries fast) and won’t give a smooth surface for polish. So that’s why I use it first, then use a base coat on top of it.So, even though I am only giving it 3 stars now, since I know it doesn’t grow my nails faster, but don’t yet know if it has made my new growth stronger, I do plan on buying again, for the uses stated above.If, after the six month mark though, my nails are in the same condition as they are now, I will quit buying, as a $2 clear coat can do the same for me as this and I will knock my rating down to 1 star.If the new growth at the six month mark is noticeably different, I will put my rating up to 5 stars and continue buying.Time will tell.Edit to add: it’s been well over six months, more like 10, and I am still using this. My nails have healed, I don’t think they’re growing out any quicker, I am having to cut them down every couple weeks.I still use this as my basecoat, as well as my protective coat if I don’t have a color on, and I do use it still to protect if I do have a color on, So my nails last one week without any touchups. My favorite feature is still how quickly it dries! As well as how lightweight it is.

I searched for a Formaldehyde free base coat polish and this came up. I received it and it does contain Formaldehyde. And surprise.. non returnable.

Absolutely love this polish!! This was my 3rd and 4th bottles (one was for my MIL). I stopped getting acrylics on my nails and this stuff was great during the “grow out” stage. Highly recommend
