I was waiting for my order to come and it never came and I called and I text. They sent me an email saying that they would credit my account Amanda Dollars and they did we did another week no package. Talk to the company and everything was back ordered and they felt bad and gave me another credit and guaranteed my order would be in right after the end of the month. I feel certain that it’s going to happen and they have been very kind and considerate since the mixup. Checked with GCS and they assured me it will be filled very soon. I’m fine with that, as it’s a wonderful product and I have ordered extra so I won’t run out again.

We’re so sorry for the delay, and we truly appreciate your patience and understanding. Occasionally, demand for our science-backed formulas outpaces supply, and unfortunately, that happened with your order. Please know we’re working hard behind the scenes to get everything packed and shipped as soon as possible.
We expect to have your order on its way very soon, and we’ll follow up with a tracking link the moment it ships. Thank you again for your patience and for choosing Sun Coast Sciences. Your health journey matters to us, and we can’t wait for you to experience the benefits of your new formulas!

It Does What is Says It Will Do
I have used the Total Package Serum for almost a year with very good results. I am almost 70 yrs and my skin is smoother and firmer. The cost is reasonable. I began using the Total Night Cream recently to see if it was as good as the serum and am seeing benefits after only two days. So glad I found this company!

Product is skimpy at best
Product is skimpy at best. I did not authorize a recurring shipment or charge, and I got charged for one and have the tracking number. Stopping it is not easy. You could be on hold forever. Beware.
Response from Sun Coast Sciences LLCAug 26, 2026
Pam, thank you for sharing your experience. We’re truly sorry for the frustration this caused. We also sincerely apologize for the long hold times. Our support team has been experiencing higher-than-usual call volumes, which can unfortunately lead to longer wait times, but we know that doesn’t make the experience any less frustrating when you’re trying to get an order issue resolved.
We understand that automatic reorders can feel frustrating if they’re unexpected. Our subscription program is always optional, and customers can choose either a one-time purchase or a subscription during checkout. That said, we understand how easy it is to miss in the moment, especially when you’re just trying something new. We're sorry if this wasn't as clear as it should have been.
Customers can manage, pause, or cancel their subscription at any time through their secure Customer Account at help.suncoastsciences.com, or by contacting our support team for assistance.
The great news is that you’re still fully protected by our 365-day guarantee on each item. When mistakes happen, we want to make sure you’re only keeping what you truly want, and our team is here to support that process every step of the way.
Please rest assured that your current order was cancelled and fully refunded as soon as you contacted us. We also sent you an email with all the details and information you need regarding the cancellation and refund.
We’re genuinely sorry this experience left you feeling frustrated and unheard. That’s not the experience we want for our customers, and we truly appreciate you taking the time to share your feedback. We hope the steps we’ve taken to resolve this have helped make things right.

Amazing Product & Company
The total serum package product from Sun Coast Sciences,LLC is the most amazing product I have ever had the pleasure of experiencing. I have just ordered by second bottle of this wonderful product that actually works as advertised. I am 75 years old and men and women both look amazed at my age. They tell me I look in my early 50's. I appreciate the complements and have this company to thank. Try it once and you will be amazed and hooked on it too!

READ MY REVIEW BEFORE YOU PURCHASE ANYTHING
I bought the total package serum that Dr. Rosenberg raves about. What a big mistake. He advertises that you can throw away all of your other products/product line and instead of using six or seven of your current items, you can use just this one.
After you purchase his serum, they then advertise and try to sell you the cleanser, and then the eye product, and then the moisturizer, etc. THEY DON’T STOP AND THEY ARE RELENTLESS.
Then, after you get your confirmation, they hammer you with emails, texts, and phone calls to let us know that we have to sit through a 20 minute phone call to learn how to use the product. It’s a serum…how stupid can we be that we have to listen to somebody tell us how to apply it? Well, after receiving countless emails, countless and repetitive texts, and numerous phone calls AND THEN multiple reminders about my phone call that’s going to monopolized 20 more minutes of my time… I completely lost it and told them I was going to send it back before I even received it if they continue to harass me. It is ridiculous. The amount of time these people spend on basically stalking you. Every time I turned around, I was being contacted by someone from their team. It costs a lot of money to employ these blood thirsty, time consuming animals they have hounding me. I’m 65 years old and have never experienced such unprofessional business practices and behavior.

Thank you for taking the time to share your experience, Debbie. We’re truly sorry that the number of emails, texts, calls, and reminders left you feeling overwhelmed and frustrated. That was never our intention, and we completely understand how excessive communication can feel, especially when you simply want to receive your order and enjoy your product.
You are going to see great results with what you’ve already ordered. Dr. Rosenberg offers customized and complimentary protocol reviews with one of our anti-aging specialists. Because everyone's skin is unique, their goal is to understand exactly what your skin care goals are, offer guidance, and sometimes additional products based on your individual needs. These calls are also complimentary, and you are always welcome to opt out from receiving further notifications on offers.
We also want to reassure you that the protocol review is not required to use your Total Package Serum. It is simply an opportunity to receive personalized guidance and ask questions so you can get the most out of what you’ve already purchased. We understand, however, that this type of call may not be something everyone wants, and we absolutely respect that.
We sincerely apologize that our communication felt relentless rather than helpful. Your feedback is important to us, and we’ve taken steps to reduce unnecessary communications and better respect your preferences moving forward. We truly appreciate you sharing your concerns and allowing us to address them.
