My skin feels amazing!

I finally tried the Crystal Retinal 6 and I'm totally hooked. My skin looks so much brighter and smoother already. Shipping was quick, too! I'm definitely going to shop here again.

Worth the investment for results

As a first-time buyer, I was a bit hesitant about the price, but I got the Advanced Day Ultimate Protect during a holiday sale. The free shipping on orders over $50 helped, and I felt I got good value. It spreads nicely and my skin feels protected all day. I'm pleased with the purchase and the savings I found.

Good product, minor shipping issue

I ordered the C-Tetra and it's been a solid addition to my routine. My skin has a nice glow now. The product itself is great, but the shipping took about 8 days to get to me in Texas, which was a bit longer than I expected. Customer service was responsive when I inquired, so that was a plus. Overall, good value for the quality.

Consistently great experience

This was my third purchase from Medik8, this time for the Hydr8 B5 Intense. Just like my previous orders for the Crystal Retinal 3 and the Press & Glow, everything arrived well-packaged and exactly on time. Their products always deliver on what they promise, and the consistency in quality and service is why I keep coming back. It's reassuring to know I can count on them for my skincare needs.

Does anyone know if Medik8 offers a student discount? My budget is tight but I really want to try the Liquid Peptides.

M Michelle Thomas 1 month ago
Yeah, I'm pretty sure they do! I remember seeing something about it. Check their site, it's usually listed under discounts.

They do! You usually have to verify through some service like UniDays or Student Beans. Got my discount that way a few months back.

Can I use two different discount codes on one order? Like a free shipping code and a percentage off one?

M Matt Rodriguez 1 month ago
Nah, pretty sure they don't let you stack codes. It's usually one per order for most brands like this.

J Josh Sanchez 1 month ago
I've never been able to combine codes on their site, unfortunately. It's usually either one or the other, so pick the one that saves you the most!

Hey, quick question about the Crystal Retinal, I'm eyeing the 6 or 10. Does anyone know if it's okay to start with one of those if I've used retinoids before, or do I really need to do the lowest strength first?

S Sam Hall 4 weeks ago
I've used other retinols for a while and jumped straight to the 6 and had no issues. My skin is pretty used to it though.

They usually recommend starting lower just to be safe, like the 1 or 3, even if you've used other brands. But if your skin is super tolerant, maybe the 6 would be fine. I'd probably still go with the 3 to start and work up.

Wondering about the shipping to New York City, does it take forever? I need a new C-Tetra serum pretty soon.

O Olivia Harris 1 month ago
Nah, it's usually pretty quick for me in NYC. Like 3-5 days most of the time.

Mine arrived in like 4 days to Brooklyn last time. Pretty standard for online orders, nothing crazy long.

Are Medik8 products genuinely cruelty-free? It's really important to me that the brands I support don't test on animals.

E Eric S. 2 days ago
Yes, they are! It's one of the reasons I started buying from them. I've checked their site before and they're clear about it.

Totally cruelty-free, they're certified by PETA I believe. It's listed on their website under their ethics section if you want to double-check the details.
