Woke this morning to a shipping email! So excited to try the product that everyone keeps raving about! Special "thank you" to the customer service team and their dedication in helping solve a minor mishap!
Response from Sun Coast Sciences LLCSep 29, 2026
Thank you so much for taking the time to share your experience. We’re truly sorry for the frustration and confusion you went through. Receiving an empty box after placing an order is incredibly disappointing, and we completely understand how upsetting it was to then have difficulty getting clear answers about your reshipment. As soon as we learned that your package had arrived empty due to a system glitch, we took ownership of the mistake and processed a reshipment immediately. Unfortunately, the communication that followed did not go the way it should have. When you reached out to check on your reshipment, our AI assistant, Luma, responded based on the original order status and indicated that your order had already been delivered, which caused additional confusion. Each time you were connected with a live agent, you were reassured that the reshipment had been processed, and we regret that you still had to reach out multiple times for clarity. We’re especially sorry that it took three separate attempts to get the help and reassurance you needed. We never want any customer to feel stuck, unheard, or like they’re going in circles. While our AI assistant did respond initially, a delay in follow-up caused it to lose context, and the experience didn’t come together the way it should have. That’s on us, and we’re actively working to improve how these systems work together so communication feels seamless and consistent. We sincerely apologize for the runaround and for the frustration this caused. We truly appreciate your patience and the opportunity to make this right.

I think my wrinkles are softening and smoothing out a bit. I’ve just started using it, so hoping for even better results. I feel that it’s quite expensive for the little container.

Thank you for sharing your experience! We’re so happy to hear you’re already noticing your wrinkles looking a little softer and smoother, especially since you’ve only recently started using your Total Package Serum. We’re hopeful you’ll continue to see even more with consistent use. And we completely understand your concern about the price, especially when the container may seem small at first glance. We know skincare is an investment, and we never want the cost to feel overlooked or dismissed. Our formulas are made with carefully selected, high-quality ingredients, but we also truly appreciate hearing when the value doesn’t feel quite where you’d like it to be. Your feedback is important to us, Virginia. We know that there are a lot of options out there, and we truly appreciate you giving Sun Coast Sciences a try!

Wasn’t happy at first still not sure. The product I really like so far but only been putting it on in morning and night. A little goes a long way. I like that. I’m almost 68 and the lines are catching up. Lost weight. 60 lbs total. Now to lose 25-30 more. I’m really hoping for some face wrinkles to soften.
Response from Sun Coast Sciences LLCJun 17, 2026
Thank you for sharing your experience and congratulations on your incredible 60-pound weight loss—that's a remarkable achievement! We're so glad to hear you're enjoying the product so far and that a little goes a long way. Consistency is key with skincare, and since you've only recently started using it morning and night, we hope you'll continue to see improvements over time. Weight loss can certainly make existing lines and wrinkles more noticeable, so we understand your goal of wanting to soften their appearance. We appreciate your honest feedback and look forward to hearing how your results progress in the coming weeks. Wishing you continued success on your wellness journey and with the remaining goals you've set for yourself! Thank you for trusting Sun Coast Sciences to support you on your journey to improved health.

Update! The Loyalty Department reached out to me and explained the confusion and their sincere apologies. Apparently I was flagged due to a reference word in my email that had nothing to do with reselling products, (as I originally thought.) Thankfully they were extremely apologetic and promised me they would take extremely good care of ALL CUSTOMERS; not just specialists like myself. He definitely seemed extremely trustworthy and genuine. We will be restarting a testing period of the TPS, along with their cleanser . This is something that will take me many months to complete. However after the very kind and genuine conversation, I feel it’s only right to give the band another opportunity. ** previous review prior to a very kind and loving phone call from the brand.** Absolutely AWFUL customer service! You see, I’m an MUA and Skin Care Specialist. Many of my clients asked if I would try their serum. First order, only one bottle when I ordered two. Plus the one I did receive lasted maybe two days. They did fix that issue. Then I went to order again because I do computer mapping (to see any actual results and that can take 6-8 months.) Somehow they flagged me as a reseller! I’ve NEVER resold a product! I’ve received millions of dollars in skin care and makeup from pretty much every brand! I’m known for gifting items to those that can’t afford something, or as a thank you. Never, ever, ever, have I sold even one product. Not that I’ve purchased, and not that I was sent! Remember, I made purchases (or tried to.) Now this company is not even apologizing! So, unfortunately I’m going to have to go to every skin and makeup account that I have (plus my makeup and skin influencer friends to spread the word that this company can’t be trusted.) Was the TPS nice? Yeah, it was decent. Was starting to prove a few improvements in mapping. But I can’t give a full review on the product as I couldn’t fully test. If they are using AI to flag people, they need humans! This was unprofessional and disrespectful! My order was from an email THEY SENT ME, buy three, get three. That would have worked perfectly for me to fully test. Unfortunately I can not recommend the brand as they aren’t professional at all. Even their “Happy Customer Service” it’s not happy, trust me! Very disappointed in this brand. In 26 years I’ve never seen such a thing.

Thank you, Sara, for taking the time to share your experience. We're truly sorry that this situation left you feeling frustrated and disrespected. That was never our intention. First, we'd like to acknowledge the fulfillment issue with your original order. We understand how disappointing it is when an order doesn't arrive as expected, and we appreciate the opportunity we had to correct that issue for you. Regarding the more recent order, we completely understand why being flagged as a potential reseller would be upsetting, especially given your professional background and the fact that you were attempting to evaluate the product over time. We want to be very clear that this determination was not a judgment of your character, integrity, or intentions. The review was triggered based on information provided during a previous inquiry regarding purchasing products for client testing and obtaining larger quantities of product. Because Sun Coast Sciences does not currently authorize wholesale, reseller, or third-party distribution arrangements, we closely review accounts when certain criteria are met. When that happens, decisions are made based on the information available at the time and are intended to ensure our policies are applied consistently and fairly. The reason we take these reviews seriously is to protect our customers and the integrity of our products. When products are sold outside of authorized purchasing channels, we cannot verify how they have been stored, handled, or distributed before reaching the end user. This can create concerns around product quality, freshness, and authenticity. Unfortunately, like many brands, we have also encountered situations involving unauthorized online sellers and counterfeit versions of our products. Because customer safety and product quality are extremely important to us, we have policies in place to help ensure customers receive genuine products directly from the manufacturer and receive the support, guarantees, and protections that accompany those purchases. We also recognize that some licensed professionals, practitioners, and specialists may wish to maintain inventory for client use or recommendations without engaging in online resale activities. In certain circumstances, exceptions may be considered after additional review. Because every situation is different, we evaluate those requests individually based on the information available at the time. Sara, we genuinely appreciate your interest in our products, your professional feedback, and the time you've invested in evaluating them. If you would like our team to take another look at your account, we would welcome the opportunity to gather additional information about how you intended to use the products and conduct a further review. We are always willing to revisit decisions when additional context is available. We appreciate you bringing your concerns forward and giving us the opportunity to address them.

This review follows the ones I wrote recently, less than favorable, not because of the product, but because of the advertising on Facebook. But, I am pleased to be able to say I was wrong, and it is primarily because of one man's devotion to his job, and his conviction that without the customer, there can be no lasting business. When I became tired of the run around I was getting in answer to a simple question about why I was seeing false advertising, their Loyalty team Manager stepped in. I didn't question the quality of their products. I questioned their advertising integrity. I was on their online site, bought one item and was immediately offered a "deal." Long story short; after an exasperating series of texts from 5 different customer service reps trying to convince me I was making a mistake, my temper flared, and Giovanni stepped in. The result was, I am happy to say, more than what I had expected considering the problems I was experiencing. I received a text from a gem of an employee, who I am happy to say, cared enough to stay with me, no longer passing me around from one rep to another. This man was exceptional in his sincere approach to my issue. From the first day he texted me, his demeanor was amazing. This was someone who truly cared about the customer, in this case, me. He was honest, honorable and gave new meaning to the word integrity. I didn't question the quality of their products. I was dealing with false advertising and then customer service reps trying to convince me I did not see what I saw. Giovanni came onto the scene after being informed of the problems I was having. This is the kind of interaction that is real, not just an employee trying to convince me I was mistaken. He had looked into every text and all I had been subjected to and he stepped in to personally see to it that I understood that he had taken the time to thoroughly look into the issue. The first thing he did was to apologize for the way I had been treated. He felt that I hadn't been treated well and was quite upset abut it. The first thing I appreciated was that he wanted me to explain and he actually listened to me; every word. That is rare in business today, and he was good to his word, never one time interrupting. And since then, he has continually written and called to ask how I was feeling about the end result, which was his decision to see to it that employees receive training he felt they needed to help them see the importance of truth, and understanding that a customer is the backbone of any company. They are the ones who keep a company alive by not only buying the product, but spreading the word, and depending on what that word happens to be, the business they are dealing with will either grow or die. Giovanni was an amazing person. He was the epitome of the kind of employee that any company would be proud to have. Dealing with him almost on a daily basis was like stepping back in time to the days when the customer was treated as though they were important. He listened, asked good questions, and I am more than happy to say that my first impression of this company was not what I think today. Giovanni saw to it that I understood that he was aware that the fault was with his employees and they would now learn the importance of truth, honesty, honor and integrity. These few words will make or break a company, and he was completely devoted to Sun Coast making the customer understand how important the time they spend with their customer is. What a breath of fresh air it is to feel as though we count. The answer to any problem of this magnitude is to understand that they can be a company that is here today and gone tomorrow, or one that we will see many years down the road. I think that this is one whose name will grow as time passes. In this day and age, it is refreshing to know that Sun Coast is doing its best to better itself when it comes to customer care. Now, the big question is "are the products as good as their Loyalty manager?" I have an arsenal of their products that I am just beginning to use. I am a bit old to expect a major difference, but I will say this. It has been less than a week since I started using their facial products and though I think it may take a bit longer to see a big difference in the "fine lines" (mine are more like deep ruts in a road), there is a major difference in the feel of my skin. It is so much softer and this is usually the first signs of success in a product. If it accomplishes nothing more than that, I will say this is an amazing product. I am almost 80 years old and I will take anything I can get, especially with a company who cares enough to see to it that they have happy, beautiful customers. Carry on Sun Coast. And remember one thing. You are more than lucky to have an employee like Giovanni. He is what will be the cause of Sun Coast's success. This is my feeling only but look for more even better.

Unfortunately I did not see positive results from the product purchases and followed the RMA directions for the money back guarantee. With that I did get positive results. Although I had to pay for return shipping (no return shipping label was offered), I did receive a timely full refund for my purchase. The process was easy and simple.

Thank you for taking the time to share your experience. We're sorry to hear that the products did not meet your needs. Since we offer free shipping on all outgoing orders, we do kindly ask that customers cover the return shipping cost for items they no longer wish to keep. We completely understand this might feel like an extra step, and we are truly sorry for any inconvenience this may have caused you.
