Too harsh on my sensitive skin for daily use
This cleanser contains a variety of emollient and moisturizing oils, but it also contains potassium hydroxide, which indicates saponification, a process that turns oil into soap. While it has the appearance of being an oily liquid, it foams up nicely on wet skin to create a luxurious lather.
It has a fresh, clean soapy scent. I can't quite place it, but it reminds me of something from a long time ago. It is a little powdery and perhaps more of a mature scent, but I really like how clean it smells.
Unfortunately, I find it to be quite harsh on my skin, which is likely a result of the saponification of the oils. One day of use here and there will be fine for me, but daily use makes my skin quite dry. In fact, it makes my skin squeaky clean, which is not necessarily a good thing. It is a shame because the scent is so nice, and I love the oil-to-foamy-lather formulation.
Another issue is that the dropper on the bottle arrived clogged. It is really puzzling because the cleanser seems to be completely liquid. I ran the dropper under very warm water for quite some time in an attempt to clear the clog, but I was unsuccessful. So, in using the product, I've just been pouring it into my hand. This could also be contributing to my issues with dryness, as no matter how hard I try to dispense a small amount, pouring the cleanser out of the bottle inevitably results in my using more than would have been dispensed from a dropper.

Collagen Eye Patches
These are the best under eye patches that I bought. I have tried others, but none provided the results that these did. I had visible results that lasted 12 hours. Puffiness reduced, smooth skin, rejuvenated look. I will be buying more when my supply is up.

Instant feeling of coolness but hoping I got what I paid for.
The box received isn’t the same as advertised but close. She picture. This is only second time trying a set from this box. They are soft and cooling. No unpleasant smell. It makes it fell like a spa day. And Hope to see results with use. At this point not breakout or reactions. That’s a good thing! Just not seeing results yet. Give it time, I know.

Very easy to use and gives good moisturizing as well
Honestly here’s how this goes . When I first wake up after a nights rest I have the worse eyebags .
So I ordered these and gave them a try .
After washing my face I applied these , I kept them on for 30 minutes . When I removed them I noticed a significant amount of puffiness gone , however there was still puffiness there . So I then applied plexaderm on top . The results with both these two products are a welcome outcome . Just on there own they do a pretty good job , however with the plexaderm I got an awesome outcome .

Great product! Must try!! 🤍
I don’t typically leave reviews but I had to with this! 🤍
I purchased this in a bundle with the moisturizer and under-eye patches. I’ve only used this maybe 2 or 3 times and my skin looks so much better. I just turned 40. My skin tone has been uneven, just overall unhealthy looking and wrinkling for years. Now it’s soft and smooth and looks great. I’ve never been a person that had good skin in the past but I am that person now. I am so impressed and this stuff is worth it for sure! I will continue to purchase it!
Also noticed, because it got on my lips, my lips look better too. They stay dry and chapped due to a medication I was on many years ago. NOTHING helps my lips but this stuff has made them completely healthy and the dryness/chap is completely gone! Only 2 times using but I noticed improvement after the first use!
Also note, a little goes a long way. The bottles are small but you don’t need a lot per use.
Also, I typically have very dark under eyes. Both genetics and sleep deprivation cause this for me. I’ve dealt with it every day for many years. Even in my teenage years and twenties. I can never fully cover the darkness, but I’ve used the eyepatches once and the serum and moisturizer twice, and my under eyes are looking better and less dark too.
I’m just overall so happy with these products! I’m so happy I stumbled across this product and decided to give it a chance! 🤍🤍🤍
