Sadly, I had to give it a one, to write my review. Ordered Total Package Serum and after using the entire package, morning and night, I didn’t see one ounce of improvement. The advertising is a marketing scam and the product is nothing but rubbish. Please check reviews on all sites before making the same mistake as myself.

Hi Juliana, Thank you for taking the time to share. We’re truly sorry to hear how disappointed you feel after using Total Package Serum, and we completely understand how frustrating that can be.
Skincare results can vary from person to person, and while many customers see gradual improvements over time, a few may not experience the changes they hoped for. We never want that to feel discouraging or dismissive. That’s exactly why every purchase is protected by our 365-day guarantee, so customers can try our products with confidence.
We believe in transparency and care deeply about supporting our customers. If a product isn’t right for you, you can start a return anytime through our self-service portal at help.suncoastsciences.com, or reach our Customer Happiness team 24/7 through the support page on our website.
We’re truly disappointed we didn’t have the chance to help you sooner, and we would genuinely appreciate the opportunity to support you and make this right.

Stay away from this company
Stay away from this company. The ordering method keeps insisting you buy more products but gives no opportunity to review the order. You're just stuck.
Response from Sun Coast Sciences LLCDec 22, 2025
Hi Patricia, Thank you for sharing your feedback. We’re truly sorry that the ordering experience felt frustrating, and we appreciate the chance to clarify.
During checkout, we do present optional additional offers that many customers choose because they provide extra value and savings. That said, these offers are never required, and customers always have the ability to complete their order without adding anything extra. We never want anyone to feel rushed or “stuck,” and we’re continually working to make the experience as clear and comfortable as possible.
Most importantly, customers are never locked into a purchase. Every order is protected by our 365-day guarantee, so if something isn’t right, we’re here to help with support or a refund. Our Customer Happiness team is available 24/7 through the support page on our website, and returns can also be started anytime through our self-service portal at help.suncoastsciences.com.
We truly value feedback like this—it helps us improve—and we’re always here to support our customers.

ReActive made by Sun Coat Sciences is a Fraud
ReActive made by Sun Coat Sciences is a fraud. So many promises of how your wrinkles are treated from within and BTW you will need 6 months worth of product. I have been taking this product for over 3 months and have not seen one bit of improvement. Totally worthless.
Response from Sun Coast Sciences LLCDec 22, 2025
Hi Rebecca, Thank you for sharing your experience. We’re truly sorry that you fell into the group of customers who didn’t see the results they were hoping for, especially after giving ReActivate such a consistent and honest try. We understand how disappointing that can be.
Wellness supplements that work from within can affect everyone differently, and factors like age, genetics, overall health, diet, hydration, and lifestyle all play a role in how someone responds. While many customers do see improvements over time, we recognize that not every product will be the right fit for every person—and we never want that to feel frustrating or discouraging.
We would genuinely love the opportunity to earn your trust by helping you explore other options that may work better for you. In addition to our internal wellness products, we also offer topical skincare solutions that support the skin directly and may be a better match for your goals.
And of course, you’re never stuck. Every purchase is backed by our 365-day guarantee, and our Customer Happiness team is available 24/7 through the support page on our website to assist you. You can also start a return anytime through our self-service portal at help.suncoastsciences.com.
We truly appreciate you sharing your feedback and would welcome the chance to help you something that works better for you.

DERMA BRIGHT MD
I went to order a bottle of Derma bright MD and it told me I hadn't finished buying. It then went to charge me for 3 bottles. I didn't go through with the sale, but it still took out 1 bottle purchase. I thought I would try it and see. I can honestly say that my dark spots got worse after using it for a month. I then went to get a refund as per their guarantee, only to be told I had to go into a website . Sadly, this website is non existing. Surprise! Surprise!!
DO NOT PURCHASE THIS PRODUCT
It's a scam.
Response from Sun Coast Sciences LLCDec 22, 2025
Hi Susan, Thank you for sharing your experience. We’re truly sorry for the frustration and disappointment you felt throughout this process, and we appreciate the opportunity to respond.
We’re sorry that the ordering experience felt confusing—that’s never our intention. Customers are always able to review their order before completing a purchase, and we’d be happy to look into what occurred on your order to make sure everything was processed correctly.
We also understand how upsetting it can be to see your skin change in a way you weren’t expecting. Skin can respond very differently from person to person, and in some cases dark spots may temporarily appear more noticeable as the skin adjusts. That said, we’re truly sorry that Derma Bright MD wasn’t the right fit for you. We know how discouraging that can be.
We want to be very clear that our refund guarantee is real and fully honored. Returns can be started anytime through our self-service portal at help.suncoastsciences.com, which is active and available 24/7. Our Customer Happiness team is also available around the clock through the support page on our website if you’d prefer direct assistance.
Again, we’re sorry that you fell into the group of customers who didn’t see the results they hoped for. We would genuinely love the opportunity to earn your trust by helping you find a product that may work better for you—whether that’s another topical option or additional guidance from our team.
With Sun Coast Sciences, you’re never stuck, and we’re always here to help.

Scam
Unbelievably bad! I was trying to order one small bottle of the serum (what a gullible sucker I am!) The website kept telling me I was not finished and didn’t I want to buy two more bottles for this low price, then didn’t I want to buy six more bottles at this incredibly low price…. I ended up leaving the website, horrified, after not ordering anything.
I noticed the next time I looked at my bank online that they had charged me for three bottles of serum. Apologetic emails arrived stating that they were so deluged with orders that they were temporarily out of product. I kept writing Sun Coast back, stating that I had NEVER ordered anything, but had been charged for 3 bottles, and that I wanted nothing but my money back. They did finally refund my money. (I had paid with PayPal. I do highly recommend PayPal, as they actually provide some help against fraudsters!) Then the product arrived a week or so after my refund. I returned it. Horrible company. Beware!

Hi Laura, Thank you for taking the time to share your experience. We’re truly sorry for how confusing and upsetting this situation felt, and we understand why it would have been frustrating.
We want to gently clarify that a charge can only be processed once an order is fully completed in the cart. Our checkout experience does include optional additional offers that many customers choose for added savings, but they are never required, and customers always have the opportunity to review their order before finalizing. That said, we’re very sorry that the process felt overwhelming at the time.
We’d also like to share that since this review was left, we’ve made meaningful updates to our ordering process. Our goal is always to improve, and feedback from our valued customers plays a big role in helping us make the experience clearer, smoother, and more comfortable for everyone.
We’re glad the charge was refunded and that the product was returned, and we truly regret that this experience left you with a negative impression. Transparency, fairness, and support are extremely important to us.
If you ever have questions or need assistance, our Customer Happiness team is available 24/7 through the support page on our website, and returns or account actions can also be managed anytime through help.suncoastsciences.com. Thank you again for sharing your feedback—it helps us continue to grow and improve.

I think this whole set up might be a scam....
24 Jan 2025 - Order made after a very long sales pitch on Facebook - when will I learn....
24 Jan - email with purchase receipt PLUS a request to buy more stuff
25, 26, 27 and 29 Jan - emails asking me to buy more stuff
29 Jan - email saying there was “slight delay” on getting stock
30 Jan & 1 Feb - emails asking me to buy more stuff
5 Feb - YET ANOTHER email asking me to buy more stuff and saying "I just got word our manufacturing team put finishing touches on our latest batch… and they’re expected to get it out the door shortly. I’ll email you the moment your order is scheduled for delivery.” (N.B. This was after it had supposedly been shipped according to the emails below)
10 Feb - YET ANOTHER email asking me to buy more stuff
12 Feb - Beth from "Customer Happiness" wrote to me with a further email saying there was a slight delay and stock would be in within the next few days. I replied to this saying to cancel the order
12 Feb - Micah from the Customer Happiness Team wrote to me saying it couldn't be cancelled as it had already been shipped on 4th Feb and gave me a tracking number that I must presume was a dummy number as I’ve since been told it hasn’t been sent at all due to a delay in getting stock PLUS the tracking number has never update its status in over 2 weeks
12 Feb - I replied to Micah as follows "If it was shipped on 4th February, why am I still getting emails, almost every day AND including today, saying there is a delay in getting stock?? Each email then somehow expects me to buy more when your company hasn’t managed to ship my first order.” I was also offered a discount to buy more - i.e. to send even more money to a company that appears to be incapable of fulfilling an order at all and refuses to cancel when asked to do so.
12 Feb - I also had an email from Lori of Customer Happiness suggesting I use the Self Service Portal to view my order status, cancel or return or even TO BUY MORE!!! I had looked at the portal, it too claims it has been shipped though it says on 3rd Feb (i.e. yet more conflicting information) and the status and tracking hasn’t moved since!! Moreover, I was not able to Cancel the order on the portal.
14 Feb - an email this time from Cybel saying "Please rest assured that your order was successfully shipped on February 4th and is currently in transit to the UK. Once it clears customs, the tracking system will generate an estimated delivery date, and you should receive updated tracking details accordingly."
15 Feb - TWO emails asking me to buy more stuff
16, 17, 18 & 19 Feb - more emails asking me to buy more stuff
19 Feb - new email from Beth saying "Our manufacturers just called to say their latest shipment of Total Package Serum - Two Bottles to our warehouse has been delayed” PLUS you are also suggesting I might want to buy more stuff!!
I have again asked them to CANCEL the whole thing.
Why is such a company allowed to operate!! Don't the same rules on Distance Selling apply to them?

Hi Barbara, Thank you for taking the time to share such a detailed account of your experience. We’re truly sorry for the frustration, confusion, and stress this caused—we completely understand why this situation would feel upsetting.
We do want to be transparent and let you know that, based on the information available to us here, we’re unable to locate your account. That said, if you’re willing to reach out to us directly, we would absolutely welcome the opportunity to review everything in detail and make things right. Helping customers resolve concerns is always our priority.
Regarding the emails: we are a direct-to-consumer company, and many of our emails are educational or promotional in nature. We understand how overwhelming that can feel, especially when there’s uncertainty around an order. Customers can unsubscribe from marketing emails at any time, and doing so never affects order updates or support.
As for the shipping confusion, we sincerely apologize. Delays—especially those involving manufacturing timelines or international transit—can sometimes result in conflicting system updates, and we understand how frustrating that is. That’s not the experience we aim to provide, and feedback like yours is taken seriously so we can continue improving communication and clarity.
If you’d like assistance, our Customer Happiness team is available 24/7 through the support page on our website, and our self-service portal at help.suncoastsciences.com can be used to review order details, request cancellations when eligible, or start a return. If something doesn’t look right, we’re always happy to step in and help personally.
We’re truly sorry this experience left you feeling distrustful. If you choose to contact us, we’d genuinely appreciate the chance to help resolve this and restore your confidence in us.

THIS PLACE IS A SCAM!
Took my money, did NOT send product. I emailed them, they said (in writing) that they had refunded my credit card back. Fast forward 9-days, they email and tell me they have shipped the product and that it was too late to cancel, this was NINE (9) DAYS AFTER they said they would refund me. I had already bought another product from a reputable company. #STAYAWAY

Don't Trust Them
The "spiel" was way beyond the stated 5 minutes, which jaded me towards the product. Then when I checked them out on TrustPilot and Amazon, many negative customer service reviews! Some positive product reviews on Amazon, but I passed on purchasing from them.
Response from Sun Coast Sciences LLCDec 22, 2025
Thank you for sharing your thoughts—we truly appreciate you taking the time to do your research and share your perspective.
We understand how the length of the presentation could feel frustrating, especially when it goes beyond what was expected. Our videos are longer by design because Dr. Rosenberg believes education is important and wants to fully explain how the products work and what customers can realistically expect. That said, we know not everyone prefers that format, and we completely respect that.
For those who prefer not to watch the full video, we offer extensive written information directly on our website, along with detailed FAQs that explain how the products work and who they may be best suited for. Our support page also includes easy ways to reach our team if questions come up at any point.
We also understand how reviews can influence a decision. While we do hear from customers when something doesn’t go as planned, we’re proud to support many happy customers and to stand behind every purchase with real people and real support. Our Customer Happiness team is available 24/7 and always focused on listening, resolving concerns, and making things right.
We appreciate you considering us, and if you ever decide to explore our products in the future, we’d truly love the opportunity to earn your trust.
