I'm a new customer to Sun Coast. I started out with the Total Package Serum and recently began the Hydrate and Restore face wash. It's a little too soon to notice tangible results, but I can say that both products are easy to apply, smell great and absorb into the skin quickly. There have been no adverse reactions. Orders ship quickly and their Customer Service is great. I also had a 25-minute Protocol session with a representative of the company. I realize Sun Coast does this to push additional product, but the session was informative about general skin health and I didn't feel at all pressured to buy more.

BUYER BEWARE
Only one star because I had to otherwise it would’ve been a zero. I hated the marketing strategy when you went to close at your order. A new product popped up at an amazing discounted price and you were asked if you wanted to add it to your purchase. This happened numerous times before I could finally close out my purchase. Not one thing that they sent me has worked as stated. Not one. I would return them, but I am passed the return date.
So here are my two cents, and I do take change, BUYER BEWARE!!!!!! Save your money do your research using trust pilot and the BBB.
I certainly hope that this helps the next person save a heap of money.

Hi Maki, Thank you for taking the time to share your experience. We’re truly sorry that your journey with our products and ordering process felt frustrating, and we appreciate the opportunity to respond.
At checkout, we offer optional add-on products at discounted pricing to give customers extra value and flexibility. Many customers enjoy these options, though we understand that the experience isn’t for everyone, and we respect that feedback.
When it comes to results, we also know how disappointing it can be when improvements aren’t visible as quickly as hoped. Skincare and wellness products work differently for everyone, and meaningful results often appear gradually with continued use over time. That’s exactly why we stand behind every purchase with our 365-day guarantee, so customers can try our products with confidence and without pressure.
In your case, we truly wanted to help and even made an exception by providing a return shipping label so you could return the unwanted products. Since they were not returned, a refund wasn’t able to be completed, but our intention was always to support you and make the process as easy as possible.
If you’d like, we would still be happy to review your account, answer any questions, or assist however we can. Our Customer Happiness team is available 24/7, and support can be reached anytime through the support page on suncoastsciences.com. We remain committed to care, transparency, and earning trust through every interaction.

I bought the product Derma Bright MD.
I bought the product Derma Bright MD.
I accidentally bought double the amount of bottles for a high $ amount. I am now onto my 3rd bottle and have found no difference to my skin tone, what so ever. I have tried contacting Sun Coast Sciences but no response. Guaranteed refund they say, if no results. Well these are liars from a company all about the upselling and not about the consumer. So if your thinking about buying a product from them, think twice. It's expensive, with no results and no refund as per the guarantee they claim. Save your money and go elsewhere!!

Manage your expectations
I bought quite a bit of product as they keep offering special deals as you checked out. From USD to AUD made it very expensive. Going by the before and afters I thought if I at least got 1/2 the result I would be happy. No improvement after 6 months at all. Yes they were helpful and friendly but it doesn't change the fact that the products made no difference and I still used all my other skincare over what I got from them as my skin got super dry. I asked them first and they said that was fine. So what are they selling, nothing special and when I asked for a refund they tried to get me to keep the product and offered 25% refund. That's sounds good as shipping is expensive but they refunded me in AUD when I purchased in USD so at 0.63 on the US dollar I got ripped off on the refund. Cut it short DON'T BOTHER!

Great customer service
I purchased the skin serum and had an issue with the quantity purchased. They got back to me right away and took care of the problem.
I have been pleased with the product and I do think my smile lines at the corners of my mouth are less noticeable.

Don’t waste your money
Had a coupon for facial. Upsold to laser treatment and promised dark spot removal. No real change after treatment. Hustled and scammed.
