I can't say yet whether or not this product has helped with the dark circles under my eyes. What I can say is that it arrived quickly, well packaged to prevent breakage, and with very clear instructions for adding it to other products at the right percent strength. I added it to my eye serum today and am excited to see how it works out.

Karry in customer service was exceptional. VERY Knowledgeable, patient and kind.

Love your products! I have been using them for several years and definitely see a difference in my skin. I have had compliments and have recommended your products to others. My order always comes quickly. I am very satisfied with your products and services.

I’ve been using Matrixl 3000 and syntack for about 3 weeks now and have noticed improvement in my skin. The main thing I can report is my skin seems to be and appears really hydrated. Another improvement I can note is that my complexion is a lot more even. I haven’t noticed any changes in elasticity or wrinkle reduction but I suppose those effects take some time to build up to. But so far so good, and I intend to continue using the products

Thank you. Arrived on time and pkg. was great !!!

You guys have been a godsend. I appreciate how much you care about the quality of your products and your customer service is amazing

All items arrived in good condition and I greatly appreciate the excellent customer service on one issue. . . thanks!

Products are in stock. Discounts are sometimes available (more, please!). Shipping was quick. Packaging was secure.

Very good for sensitive skin. you don't need to look any where else if you are looking for peptide serum

Shopping and service is great.

My experience so far with this company has been great, I plan on having many future orders from here for my at-home remedies.

I am an Esthetician and love these products and their ingredients!!! Seriously! The only thing that bothered about my last purchase is that, in the past every serum or booster I have purchased is alway the same size 1oz. This past purchase I decided to try the wrinkle eraser, and It was a wopping $100 for only .5 oz. I know all the ingredients and I can see it being a little bit more than, lets say their peptide infusion or their ageless serum, but double the price for half the amount. Sorry guys, but NO!

My delivery and packaging were done efficiently. Happy to have found this source of great products

Everything went great with expedient shipping.

It's too early to tell if they're working on me, but they feel nice on my skin. I've mixed a couple of them with my moisturizer. I hope to know soon if and when they work
