I think I'll grab another bottle of this.
Size: 1 Fl Oz (Pack of 1)
Works fine I believe this gives my argireline & matrixyl 3000 along with copper peptides a really good boost actually, I wasn't that impressed at first but now I've been using it a while I can tell it's been helping .
It's NOT greasy at all and absorbes really fast and well.
I've noticed some of my wrinkles have deminished and some have softened a great bit.
It's semi thick but not where it's sticky or tacky. Just enough that it doesn't feel or look like water. Which is great consistency.
I've noticed my darker spots and skin has brightened up a good bit where I had more skin issues from the sun has lightened up but this also could be a number of products that I am using. But I do believe this one has been helping a good bit with my others. I'd get this again

Amazing!
Size: 1 Fl Oz (Pack of 1)
I absolutely love this product. I use it daily in the AM and PM and it's a staple in my skin care routine. Glides on, absorbs quickly, noticeable difference in fine lines, much better (and more affordable) than other name brands I have tried.

Love Good Molecules
Size: 1 Fl Oz (Pack of 1)
I’m learning a lot about peptides for skin and this product was recommended by so many people, in so many different places, that I gave it a try. And I don’t regret it.
The price is phenomenal, I love the ingredients, I have sensitive skin with mild rosacea on my cheeks, and it does not aggravate my skin whatsoever.
It goes on so smooth and dried so fast. There is absolutely no “film” it does not feel heavy or weird on my face either. Almost feels like water TBH.
I’ve been using it twice a day for over a week now and I definitely can feel and see a difference! I thought maybe I was just fooling myself or imagining things but definitely not.
My friend told me that my cheek look “less inflamed” and that the lines on my forehead are looking a little “less severe” (not that they were so bad to begin with lol but it definitely speaks volumes about the product)
I don’t smell anything so I don’t think there is a fragrance
As far as brightening my skin, I can’t honestly tell a difference in that aspect.
But overall, it has done something noticeable with my skin redness and sensitivity, it has helped with minor plumping of smaller lines, it adds a nice “bounce” to my skin, nothing major or crazy, but noticeable enough to the naked eye.
And this is using it twice a day for over seven days now – in conjunction with a few other products I use,
but I am noticing that I am using less product products now.
Now I am just down to my eye cream and my cicapair serum for redness/sensitivity & my fave good molecules Yerba Mate eye gel (I used it on my forehead lines too!)
And I like the size of the bottle. Especially for the price. It feels very nice and soothing on the skin. I have to be careful that I don’t use too much lol
I cannot wait to check out other items from this brand
The two items I use are so good, affordable, and impressive. Plus multi use.
This one, I put it on my lips as well. The Yerba is great for my forehead lines and I put it on my neck/under chin area too.

Great to add to your routine without spending big money.
Size: 1 Fl Oz (Pack of 1)
I’ve been using this in my skincare routine for about a month and I love it. It has helped my skin texture and elasticity. It’s also an amazing price. The Good Molecules line is a hidden gem that doesn’t require you to spend an outrageous amount for a serum. Make sure to let it absorb in before you apply the rest of your products, as it takes a minute to dry down. It seems very effective, has brightened my skin, and can be used every night. I’ve had it for about a month and still have half the bottle, so it’s a decent size. My skin was so dry before I started my new routine and I think this serum has helped. The consistency is like a little thicker and will feel a bit tacky after use. I use it after cleansing and before I use my snail mucin serum. Will buy again when I run out.

Great quality, great price.
Size: 1 Fl Oz (Pack of 1)
So far so good. This is my 2nd bottle. I mean, it’s not botox. But it’ll definitely plump and hydrate. I have dry, weird sensitive combination skin (and I’m 39), but this works and I love it as a first step in my rituals. (I also love their caffeine eye cream!)
