Excellent gentle creamy light foaming non-active cleanser - better than PC!
Size: 5 Fl Oz (Pack of 1)
Oh my goodness I LOVE this cleanser! I already have and use Remedy deep moisturizing cream in the white bottle- it is an excellent basic, no actives, hydrating moisturizer that is perfect for post laser or if you have any flare ups and cannot use actives. Oily skin will not like it, it is too moisturizing and it will not absorb fast enough for you. Their lighter version will be better for you. My HG lip balm is remedy- it is like lip silk, stays nicely balmy and last for about an hour then dries down and my lips are still moisturized and I am not searching for my lip balm to rehydrate—- exactly what I want in a lip balm, especially after wearing a lip color that dried me out. My other HG lip balm is Mario b and perlier. For reference I greatly dislike Sara h and lanege. Ok so now you know what I like and what I do not like so you can better understand what I think of the product and how this might work out for you. This cleanser is perfect for both oily and dry because of how it goes from a cream to LIGHTLY foaming. I use PC ultra hydrating cream cleanser for years because it so creamy and leaves my skin soft, but I do need to cleanse 2x if I wore heavier makeup and/or sunscreen that day because it does not foam at all—- which is a very good thing for those with dry skin. The foaming agent can be too drying for many w/ dry skin. That cleanser has also went sky high in price to nearly double what it was 5 years ago. Here comes this new remedy cleanser, my new HG! Remedy has somehow found a happy sweet spot with just enough foam to get at the sunscreen and mascara, but is still nice and creamy that leaves my skin soft! It is also half the price of PC, which it should be because there aren’t any expensive actives in this to drive up the price! This is a GOOD thing in your cleanser. You do not need actives in your cleanser unless you are going to leave the cleanser on your skin for at least 10-15 min. Very rarely do I have time for that- I gotta get in and get moving. I’ll spend that time on my post shower skincare and hair are and maybe a quiet cup of coffee. This is hands down one of the best cleanser I have ever used. Someone mentioned they used the remedy cleaning balm first and then this cleanser it was fantastic together—- ty for that tip! I will be trying that!

Amazing Product and amazing price.
Size: 12 Fl Oz (Pack of 1)
Remedy has done it again. This is an amazing face wash. I have all the remedy products now. I would highly advise if you are wanting to try Remedy but worry about cost. This product is a great start. It’s a very large bottle and feels so silky and smooth yet cleans and leaves your face ready for whatever you have planned!

Very hydrating
Size: 12 Fl Oz (Pack of 1)
I never liked foam cleaners, so I was afraid to try this one because it is a "cream-to-foam" cleanser. But it is not that foamy. I don't find it to foam at all actually. It lathers like a regular cleanser. I love it. I am slowly transitioning to all Remedy products. Trying one new thing every couple months until I have a complete Remedy routine that fits just for me!
