Temu size for Amazon price
Size: 1 Fl Oz (Pack of 1), Size: 1 Fl Oz (Pack of 1)
This lotion is great. I feel like I got ripped off. I wish I read how many ounces it was before purchasing it. Boy was I surprised paying amazon price and receiving Temu size. That is AA battery for comparison.

I should check the size
Size: 1 Fl Oz (Pack of 1)
This wasn’t the lotion I expected but I should
Probably check the sizes before ordering. This is a mini bottle. Not as moisturizing as I’d hoped for. Very light water consistency. Not my favorite lotion.

Hand lotion
Size: 1 Fl Oz (Pack of 1)
This lotion does what is said it will. I used it and my hands are extremely dry from washing them all day while at work. Once I’m home I use it and my hand feels silky smooth without the greasy feel afterwards.

SMALL! Don’t waste your money!
Size: 1 Fl Oz (Pack of 1)
I should’ve looked closer when purchasing because this is a super small sample size that isn’t even as big as the travel size and yet I paid as much for it as a regular size. What a joke! The product itself is great but I would’ve never ordered this size if I’d known it was going to be sooooo small. What a ripoff!

Obsessed. Soothing, effective, fragrance-free, incredibly healing
Style: Tolerance Daily Foaming Facial Cleanser
I’ve been loving this so much I bought a second bottle after a few days of using it. It has all the skin soothing benefits of the tolerance lotion cleanser, but it’s also a really great cleanser. It’s almost not noticeable how good it is at cleansing because your skin doesn’t feel stripped after, but it takes things off really quickly. I was worried because it doesn’t foam a lot and it feels so nurturing — much like the tolerance lotion cleanser (which I use as a second cleanse when my skin needs a few days to recover from something like a derm office treatment) — but when I wash again with my favorite HG cleanser nothing extra comes off, and I tested it twice on waterproof eyeliner that I’d swiped on my forearm for an hour or so, the eyeliner dissolved and wiped off with two or three gentle swipes. It has a very emollient texture, so when you rub it against your skin it slips so easily you don’t realize it’s dissolving and taking things away because there is no friction. So it’s great at taking off makeup, it’s AMAZING at cleaning makeup brushes, and IT DOES NOT BURN MY EYES AT ALL. Also, it is FRAGRANCE-FREE… before I bought it I read a review complaining about smelling a citrus fragrance, that person either has some sort of brain tumor or something spilled on their bottle when it was in a warehouse because this is definitely a fragrance-free product.
Prior to trying this, I had tried another cleanser that gave me weird acne hives all over my chest (never happened to me before) and I was struggling to heal the acne and the irritation. I noticed an immediate difference when I started using the tolerance cleanser on it; the fresh redness went away, the acne started healing, and the post-inflammatory hyperpigmentation has been healing fast. So I’ve been using this on my body as well and it’s soothing and moisturizing in all the places where other things have been drying. I have mild rosacea and I hadn’t realized how irritated my skin was from the last thing I’d tried until after 5 days or so of using this my skin tone looked much more even and the stubborn PIH I have from a two-zit hormonal breakout a month ago finally looked dramatically lighter (as recently as the week before, I’d needed to cover them with high-coverage concealer).
Because this doesn’t foam much, some people might not realize how well it’s cleaning… I encourage you to judge it based on how your skin looks and feels. Since it is very emollient though, I do think it’s important to use it with a face wash scrubber or washcloth just to ensure you’re getting some mild mechanical exfoliation and clearing away skin cells that could be trapping stuff in your pores. For this reason, I do wash my face with this twice so the first wash can get off makeup/debris/oil and then the second wash can really penetrate and clean my skin.
