I’d say the second day it started to peel a tad bit. Definitely within the first week my feet were peeling in much larger pieces. Was gross but satisfying to see that dead skin come off. When applied it did tingle a little but not bad. I didn’t have any reaction either. My feet don’t have the really thick dry pieces anymore and look like “normal feet” again. On the sides or my heels and big toes where previously was extremely dry and rough are tougher feeling there than the rest of my feet. But they aren’t dry looking or anything. I used both packs of masks and I waited two weeks in between. It was worth it!Vender was fine, product arrived in a timely matter. It would have been better if the instructions on the package had been with the Amazon ad. The product takes 5-7 days before user sees results. I applied it as soon as it arrived and I'm still waiting to see if it worksAt first I didnt think these worked as well as others I've tried. It did take a bit longer to show results but it worked great after the wait. Would buy againIt came quickly but there was also a 1000 piece puzzle in the package as well.Me lo puse el minimo que indica que son 50 minutos. Al dia siguiente se me empezo a caer la piel d la planta de los pies, increible. Pero !!! Me quemo la parte superior de los pies, tengo como mini burbujas y me pican y arden mucho. Es muy fuerte para mi piel y no tengo una piel delicada.I tried 1 set. It doesn't work the way it says. It did nothing for my feet. Waste of money. False advertisement. No sent of lavender and just made my feet wet and stickyLove! Have tried a few other brands. This one says it takes a week to start peeling. I run it in thoroughly after leaving on for 75 minutes. My feet started to peel 2 days later and now they are soft until I need them again. Highly recommendDon't use it My feet are broke out with red bumps all over my feet and they are swollen and itchy don't use itOk, so side note - I work in a foot fetish club so I have used these kind of things A LOT in the past. Plus lockdown/no access to pedicures, I needed something to keep on top of the money makers!!I read the reviews of people saying the socks were too harsh so here's what I did:I popped the socks on and covered them with cotton sock for 45mins ONLY. Wiggle your toes, massage your feet, make sure they're covered.After 45mins, wash your feet for about 5/10mins - take a shower, a bath... whatever, just get it off your skin.Dry your tootsies and cover them in an oil based moisturiser of your choice and pop some clean cotton socks on.In about 3/4days your soles will start to peel - I'm a picker, so I did have some great satisfaction with pulling the skin at this point. But always make sure your feet are drowned in oil/cotton socks.At about day 5/6 I got a bowl of hot water and soaked my feet for about 2hrs, topping the water up whenever it got cool.The rest of the dead skin can be rubbed off at this point but keep moisturising!Get an exfoliator mit to get those last little bits and you will now have beautifully soft feet :)So I gave it 4*s because it does work, if you completely ignore the instructions!Hope this helps you all :)Leí un montón de opiniones antes de comprar estos calcetines. Tengo tendencia a tener durezas y grietas en los talones y tenía los pies bastante mal (foto 1), con lo que decidí dejarme puestos los calcetines 90 minutos, para que fueran realmente eficaces. A la hora, me empezaron a molestar (una sensación de calor, no muy agradable) por lo que decidí quitármelos. Una vez lavados los pies, la sensación que tenía en algunas partes era la de haber pasado un día en la playa sin protección y haberme quemado. Después de secarme los pies no pude evitar darme crema hidratante. Durante dos días no noté absolutamente nada. Al tercer día (foto 2), se me empezaron a pelar los pies. El cuarto día mis pies daban asco (foto3), los dejé a remojo en agua tibia y los lavé con jabón exfoliante. Así tres días por lo menos. Al cabo de 8 días mis pies parecen nuevos, hace años que no los tengo tan bien. Eso sí, el ver despellejarse los pies no es muy agradable, en algunas zonas pierden varias capas, por lo que da la sensación de que no se va a terminar nunca. Para no ceder a la tentación y retirar las pieles, yo he usado crema de pies después de lavar y secar e inmediatamente después me he puesto calcetines de algodón.Absolutely horrendous!!! I used this last night my feet feel tight, swollen and unbelievably itchy. I'm in so much discomfort i could cry I've taken an antihistamine but I've still scratched my toes so much they're bleeding. I can't imagine something that makes you so uncomfortable is good for you I won't use the other two in the pack they'll go straight in the bin. Awful!!!I disliked the “ usage” instructions as the punctuation and grammar is absolutely atrocious, although it was written by somebody with broken English, I am now concerned on whether to actually use this product?I am doing this review on behalf of my girlfriend as I had purchased these for her. She did the patch test as normal and had no problem with it. Then, almost immediately after removing the foot masks her feet were starting to swell and became really itchy. She washed of the residue as she thought she was having an allergic reaction. About a day later a razor burn type looking rash had appeared on her feet and she said it was quite painful. It has now been a couple weeks since she has used them and there has been no improvements. No amount of sudocrem or rash cream has been able to get rid of it, we are now concerned that this may be a permanent thing as her feet now look like she has chemical burns on them. I wish to get a response from someone that works for this company as something has to be done about this!
