Difficult to return-Some Ingredients Have Potential To Cause Abdominal Upset
I went to the same site where I purchased three bottles and requested to return the product for a full refund. I have had the product a week or so, but stopped using it after 6 or 8 pills because it gave me terrible stomach aches, bloating, upset stomach, etc...which is what I listed as the reason for the return.
THEN, I learned, not only would I have to repackage it and pay the postage to return it, which will likely cost $15+/-, that in addiiton to that I'd have to email the tracking number and other information to the email they provided because, otherwise, they wouldn't know I was returning it and it would delay my refund, which could take months even if I followed all of their rules to return it, it said.
I don't feel like this, "...if you are not absolutely happy...." rhetoric that's all over their site and what the pitch man-doctor says multiple times in his infomercial, you can get a full refund, is actually true.
While I might eventually get a refund, I have to go to a lot of trouble to go somewhere and get it packaged to return AND pay the postage, instead of them sending me a prepaid package to stick in my mailbox for pick up like most reputable companies do.
They are marketing to an older crowd, and as odd as it might seem, many women in my age group(I am 63) are unable to drive due to health/mobility issues and I am no exception. I will have to ask someone to take this and return it for me or drive me there to do it. These things make returning the product extremely difficult for me and inconvenient. If I can't get help to do it, I will just be stuck with a product I can't use and also out $117
I like supplements and had no intention of buying these and returning them, but THEY MAKE ME SICK. I generally don't get sick from supplements, so maybe it's one of the ingredients I have never had, dunno. I am upset because:
1. Their advertisments, including the unncessarily long movie length informercial, is misleading about returns. It also doesn't advise potential customers to research the ingredients and gain awareness of potential negative side effects of their product.
That Saw Palmetto, I have since learned, is likely what made me sick to my stomach. Had I read about that in advance I wouldn't have bought this. That, and it can alter blood sugar readings, etc...another reason some people wouldn't buy it in the first place. I don't doubt the product can do what it says, but it isn't for everyone and when we, the customers, find that out, we are penalized for it with wasted time, upset stomachs, and the cost and headache of a return.
2. I am going to have to pay to return it
3. I am going to have to ask someone to get the packaging and bring it to me and then take it and/or me to UPS or wherever to return it.
Saw Palmetto(So says Drugs.com and other places)can cause:
NAUSEA*VOMITING*DIARRHEA*STOMACH PAIN, etc.........which I got after about the 4th or 5th pill. It took several days before symptoms went away entirely.
I am so disappointed.

Dear Kimberly,
First, thank you for taking the time to share your experience. We’re truly sorry to hear that you felt unwell and that the return process added to your frustration. That’s not the experience we ever want you to have, and we are here to make things right.
Regarding the stomach discomfort you described, we completely understand how upsetting that can be. RejuvaTress contains a low amount of Saw Palmetto, a plant extract commonly used to support hair health. While most people tolerate it very well, some individuals may experience digestive symptoms such as nausea, bloating, or stomach discomfort — especially if it’s taken on an empty stomach, as noted on the label. That said, we understand that everybody is different, and sensitivities can happen. Whenever starting a new supplement, it’s always wise to check with a doctor first, particularly if there are any medical conditions, sensitivities, or medications involved. If something doesn’t agree with your system, we absolutely respect your decision to stop taking it.
In regard to the return process, we’re very sorry for any confusion or added stress it may have caused. We truly try to make the steps simple and transparent, but we understand that when mobility or transportation is limited, even small logistical hurdles can feel like a burden.
Please know that we stand firmly behind our 365-day guarantee. The only requirement for a refund is that any unwanted product be returned to us. This applies even if the bottles have been opened or are completely empty, as long as they are sent back, we issue a full refund for each bottle received.
When customers provide return tracking (proof of return shipment), their refund is processed right away. If return tracking isn’t provided, the refund is processed once the warehouse receives and logs the return, which can take anywhere from a few days to weeks, depending on staffing and volume. For reference, these details are outlined in the return instructions available inside the customer account when setting up a return.
Most importantly, our Customer Happiness Team is here 24/7 by phone, email, SMS, or chat to walk anyone through the process step by step. We never want someone to feel stuck or unsupported. All of our contact information and our full return policy are always accessible on the support page of our website, suncoastsciences.com.
Finally, Kimberly, we truly appreciate you giving our product a try and sharing your honest feedback. We’re listening, and we want to make this right. We’ve reached out directly so we can personally review your situation and work toward a resolution that feels fair and helpful. Your experience matters.

Always Satisfied
We did have a little 'mixup' with my order, but it was corrected quickly-I have been using Sun Coast products for several years--All of them--and could not be happier--As a 79 year old retired - often mistaken for someone in their late 60's, who could complain!!

Thank you so much for your kind words and for being a loyal Sun Coast customer over the years!
We sincerely appreciate your understanding regarding the recent mix-up, where your complimentary Total Package Serum was unintentionally left out of your order. We're very glad we were able to quickly send it out to you and make things right!
Hearing that you’ve been enjoying our products for several years absolutely makes our day!
Your support means the world to us. If there’s ever anything we can do for you, please don’t hesitate to reach out. Here’s to many more happy, healthy years ahead!
The DermaBright was very effective…
The DermaBright was very effective within a week and continued to reduce the dark spots on my arms and legs over the next two months.
I then agreed to try the TotalPackage Serum which was very effective at reducing wrinkles and made my face, legs and arms look younger. I got compliments from younger people that I worked with.

Grateful for Sun Coast Sciences
I just love Sun Coast Sciences! Not only are the products extremely effective, their customer service is above and beyond any other company I’ve ever experienced. I’ve been taking Bioshield and Detoxithin for over two years now and I am a customer for life! I suffer from numerous autoimmune disorders and both of these products help me significantly! Whenever I’ve had any issue (eg. forgot about a recurring order or ordered the wrong product), the customer service agents are ALWAYS available to help via text or phone instantly. They always do everything they can to save me money too! I am looking forward to trying their skin products too! So many good things about these products and this company. I am grateful.

Not for Me
Unfortunately, I didn’t see much of a difference after using Total Package Serum for a month. My skin didn’t feel any different, and I wasn’t happy with the scent either. I’ll be trying a different product next time.

Happy Customer
I am already a happy buyer with Sun Coast Sciences. I have used their Total Package Serum for 6 months and no longer use any other product! It is a combination of Vitamin C, Hyaluronic Acid, and Tri-peptides. I no longer need separate products and I love it! I reached out to Sun Coast Sciences after placing an order for a new product today. I wanted to ensure I have the confirmation email and log in to manage the new subscription I placed. Christy emailed me back within the hour with all information I needed! She was efficient and helpful. I appreciated that there are no hoops to jump through if I want to change anything in my account! I can’t wait to try the Complete Eye Serum I purchased today!

A trustworthy & well organized company with outstanding products
I’ve been ordering products from Sun Coast Sciences for a number of years. The company continuously has researched, improved and responded to the rapidly changing health & fitness as well as cosmetic health needs of what I consider a population that has been sorely let down by the standard medical system and the outrageous beauty industry. Dr. Mark Rosenberg’s highly informative posts in how and why products are developed are greatly appreciated as well as scientifically verifiable. Ethically, the company recognizes that different products have varying outcomes when used by different people. They honor their clientele with a generous return policy. Their customer service team are well-trained professionals who know the products and the kinds of glitches a buyer might encounter when placing an order. That’s pretty amazing given how so many on-line customer service people are like broken records, unavailable or down right rude. I am a big fan of their skin care products, both topical and interior. I believe the products I use have had a significant impact on my sense of well-being and physical appearance. One other brilliant aspect of their on-line website is the customer private portal which I find provides me with complete, accurate information. It’s a pleasure doing business with the pros at Sun Coast Sciences.
