Reliable for DIY ingredients

I've been coming back to Skin Actives for my DIY ingredients for a while now. This time I picked up more Niacinamide and some Sea Kelp Bioferment. Just like my last few orders, everything arrived well-packaged and the quality is consistent. I trust their actives for my custom formulations, they always deliver. It's why I stick with them.

So happy with my order!

Oh my goodness, I just received my Anti-Aging Cream and a Custom Formulation Kit and I'm already in love! The cream feels amazing, and I can't wait to start experimenting with the kit. Everything was packaged so nicely, and it came even faster than I expected. I'm definitely going to tell all my friends about this place, I'm so excited to try more!

Good products, slight shipping delay

I ordered the Antioxidant Serum and the Skin Brightening Cream. Both products seem high quality and are making a noticeable difference after a few weeks of use. The serum absorbs well without feeling sticky. My only minor issue was that shipping took almost 8 days to get to me in Florida, which felt a bit long compared to other online stores. The packaging was secure though, and nothing was damaged. Overall, I'm happy with the skincare itself.

Decent value for quality ingredients

I was looking for a good deal on Squalane and found it here. The price was competitive, especially with the free shipping since my order was over $75. I compared it to a few other places and this felt like the best bang for my buck. The product itself is good quality. I feel like I got a solid ingredient without overspending, which is always the goal for me.

Good stuff, really works

I grabbed the Vitamin C Serum last month and it's been pretty nice. My skin looks a bit brighter, not like super dramatic but definitely an improvement. Shipping was quick too, got it in about 4 days. I'd probably buy it again when this bottle runs out.

thinking about trying Skin Actives instead of The Ordinary for my Vitamin C, is it worth the price difference?

T Tom Reyes 1 month ago
Totally. I switched from The Ordinary's Vitamin C and the Skin Actives one just feels more potent and effective for me. It's an investment, but I noticed a bigger change.

R Renee Ito 1 month ago
I've used both. Skin Actives feels like a step up in quality and efficacy, especially for actives. The Ordinary is good for basics, but if you want something with more oomph, Skin Actives delivers. Plus, you can often DIY stuff cheaper with their ingredients too.

Hey, wondering if anyone knows how long shipping usually takes to California for the EGF serum? Need it kinda quick.

What's their return policy like? Got cold feet about a DIY kit and might want to send it back.

O Omar D. 2 months ago
I returned something once, it was super easy. Just contact them within 30 days, I think? As long as it's unopened.

T Tara H. 2 months ago
Yeah, if it's new and in its original packaging, you have 30 days from the purchase date. I had to return an accidental double order and it went smoothly. Just make sure to reach out to their customer service.

Can you use more than one discount code at a time? Got a few from their newsletter and some points built up.

D Dana Brooks 2 months ago
Nah, only one discount code per order. But you can usually stack your rewards points with it, which is cool.

I Ivy P. 2 months ago
They're pretty strict on the one code rule, but definitely use those points! Free shipping over 75 bucks too, just so you know.
