Have not used but have question. I have a very expensive blue light that i have jut started using. Ii'm looking for a wrinkle and line diminisher which it originally said it was but now doesn't mention. Did not listen to "speel" as it is WAY TOO LONG". Pinpoints would have for most of us. Give a choice.

Thank you for sharing your feedback! We understand wanting clear, straightforward information without having to sit through a lengthy presentation. Our Total Package Serum is formulated to target four signs of aging, including fine lines and wrinkles, sagging skin, loss of firmness, and uneven skin tone. It combines Vitamin C, Hyaluronic Acid, and peptides to help support smoother, firmer, more youthful-looking skin. With consistent use, many customers begin noticing improvements within a few weeks, with results continuing to develop over time.
We also appreciate your suggestion to offer a choice in how customers learn about our products. We want you to have the information you need to make a confident decision, without the extra time commitment.

I love the way it feels on my skin
I love the way it feels on my skin. Only had it a few days so no results so far.

Too much sales patter post purchase
I watched a very lengthy video which lead to my purchase. Post purchase, I have also received further emails containing lengthy videos and sales patter on products I have purchased. I don’t need these, I have already signed up. I’ve also been hounded for appointments which I don’t want. I would prefer a comprehensive information sheet detailing the best application methods, order or application etc or one very factual video on exactly that, without all the sales patter which began to grind me down and made me worry about what I have signed up for. Then I received the product. My first impressions are good but after only 3 days use, it’s early days.

Thank you for taking the time to share such thoughtful and detailed feedback. We completely understand where you’re coming from, and we’re sorry that the amount of post-purchase communication and sales-focused content left you feeling overwhelmed or concerned about what you had signed up for. That’s certainly not the feeling we want to leave you with.
I understand that our video presentations can feel a bit long. They’re designed that way so Dr. Rosenberg can fully explain the science behind our formulas, the research that goes into them, and the real-life results our customers experience. Many viewers appreciate having that deeper insight, but we completely understand that some people prefer a quicker, more straightforward overview—especially after they’ve already made their purchase.
We also hear you on the appointment invitations and additional product emails. Your feedback is very helpful, and we’ve passed your comments along to our marketing team for review. We agree that having a clear, comprehensive resource outlining the best application methods and order of use would be helpful.
If you’d prefer to skip the videos in the future, you can always visit our website directly to read about each product in our online store, or check out our FAQ section on the Support page for quick answers.
We’re glad to hear your first impression of the products is good, and we hope you continue to enjoy them as you give them more time. Three days is certainly early, so we appreciate you keeping an open mind and sharing your initial experience with us. Thank you again for your honest feedback—we truly appreciate it and are grateful for your interest in Sun Coast Sciences!

Long winded advertising ploy
I have just ordered 3 bottles of serum but lost about 40 minutes of my life having to listen to the over repetitive video to get to the ordering, then another video to complete the order then a plethora of other special offers to finally secure my original order. I appreciate the science behind the formula but I hate this kind of long winded, time consuming and quite frankly boring advertising. I hope I enjoy the product more than that ridiculous marketing!!
Response from Sun Coast Sciences LLCAug 16, 2026
Thank you for sharing your honest feedback. We completely understand that the presentation can feel long, especially when you’re simply ready to place your order. Our videos are intentionally detailed so Dr. Rosenberg can explain the science behind our formulas, the research, and the results customers have experienced.
Many viewers enjoy getting that deeper insight before making a decision, but we completely understand that some people prefer a quicker overview.
For future orders, you can always visit our website directly to browse products without watching the full presentation, or check our FAQ section for quick answers. We’ve also passed your feedback along to our marketing team because we genuinely appreciate hearing what could make the experience better.
We hope you enjoy your serum and that the product itself makes the 40 minutes feel a little more worthwhile! Thank you for giving Sun Coast Sciences a try.

Total Package Serum
Total Package Serum, states it reduces fine lines and wrinkles. Using twice a day after face cleaning for 30 days, did not see any improvement on fine lines and wrinkles. I’m 77 years, this Serum might be better on a 55 year old. Disappointed in the product
Response from Sun Coast Sciences LLCJul 20, 2026

Everyone's skin is different, and factors like age, skin type, and individual needs can all play a role in how products perform. We'd love the chance to learn more about your experience and see if there's anything we can do to help. Our team is always here to answer questions and support you however we can.

You can cancel your subscription, but they still sent it and charge it for it
First of all the product does not work on me. Somehow I got signed up for a subscription which popped up in my email on 23 May. I canceled that subscription that day but still received the product was charged for it. Now I have to go through the hassle of sending it back in order to get a refund, plus I have no idea if I have canceled all the future subscriptions. Unless you are happy to receive the product and pay for it on a consistent basis and no longer wish to cancel, this is probably a good company to do business with. Otherwise, I would say it’s a little bit of a scam.
Response from Sun Coast Sciences LLCJun 3, 2026
Thank you so much for taking the time to share your experience, Denyce. We’re truly sorry for the frustration this caused you and completely understand how upsetting it must have felt to receive a shipment notification and charge so soon after starting the product, especially before having enough time to properly evaluate your results.
To provide some clarity, our shopping cart defaults to a subscription option, and a one-time purchase does need to be selected during checkout. That said, we understand how easy it is to miss in the moment, especially when you’re just trying something new.
Because we process orders quickly to get them out as soon as possible, timing can be tight — which is why we’ve built in multiple ways for customers to quickly manage or cancel orders through their secure 24/7 Customer Account. We make this accessible through phone, email, chat, and our support page, and we aim to include it in every interaction so it’s always within reach. What likely happened is that your order was already too far along in the shipping process to cancel when you attempted to do so through your customer account. I sincerely apologize for any inconvenience this may have caused.
Your feedback is incredibly important to us, and we sincerely apologize if the subscription process felt unclear or in any way. That is never the experience we want our customers to have. 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.
We would appreciate the opportunity to connect with you further to ensure that this matter is resolved to your satisfaction. A member of our dedicated Customer Loyalty Team will be reaching out to you personally.
We truly value you, and we would love the opportunity to earn your trust back and provide the level of care and experience we’re known for.

I have only used 1week
I have only used 1week. And I have not let go off the products I have used for 20yrs. I am a little apprehensive as to letting go of my old regiment. So even been mixing the two a little of this and then using my cream night. I think I need to jump in for at least a month. I truly want to experience with one product and get a clear view.
Response from Sun Coast Sciences LLCMar 27, 2026
Thank you for sharing your honest experience—we completely understand where you’re coming from! It’s not easy to switch from a routine you’ve trusted for 20 years, and it’s perfectly natural to feel a bit apprehensive.
Easing into a new product the way you are is a great approach, and giving it a full month on its own can definitely help you see its true benefits more clearly. Skincare often takes a little time, and consistency really makes a difference.
We appreciate you giving us a try and being open to the process. If you have any questions along the way or want guidance on how to transition your routine, we’re always here to help!

I continue to buy BioShield MD…
I continue to buy BioShield MD (Targeted Immune Support supplement). I believe this supplement helped my immune response improve during the COVID-19 era (starting 8/7/2022). I rarely get a common cold after using this immunity support for about 3 months. After the 2nd COVID vaccine update, I ceased taking COVID vaccines -- because I did not trust the efficacy of the vaccine, and because I was finding my immunity substantially improved by routinely taking the BioShield MD supplement. I have reduced my BioShield MD dosage to 1/2 their recommended dosage, which means I take 1 pill per day. I also take Vitamin C with rose hips.
I find their website very difficult to navigate -- though it is better than it was in 2022. It seems that they will not spend enough on their website to make it reliable -- though I am able to login with the same credentials for 3 1/2 years.
Also, their pricing is annoying. I buy 6 bottles at a time (once a year) to save money. But the pricing for 6 bottles, which started at $160.38, has remained about $30 higher after that first order.
Response from Sun Coast Sciences LLCMar 6, 2026
Thank you so much for sharing your thoughtful review and for being a long-time BioShield MD customer since 2022. We truly appreciate the time you took to share your experience.
It’s wonderful to hear that BioShield MD has become a consistent part of your wellness routine and that you’ve personally noticed improvements in how your immune system responds. Many customers choose BioShield MD specifically to help support a strong, balanced immune system year-round, so it’s encouraging to hear that it has been helpful for you. Pairing it with Vitamin C and adjusting the dosage to what works best for your routine is a great example of how people personalize their wellness approach.
We’re also grateful for your honest feedback about the website. While we’re glad to hear it has improved since 2022, we absolutely understand how frustrating it can be when navigation isn’t as smooth as it should be. Our team is continually working on improving the reliability and user experience of the site, and feedback like yours helps us prioritize where to make those improvements.
Regarding pricing, we completely understand how that difference may have seemed confusing. We want to reassure you that the price of BioShield MD itself has never been increased. From time to time, we run special promotional offers for new or returning customers, which is why your very first order may have been at a lower promotional rate. Outside of those limited-time promotions, the standard bundle pricing has remained consistent.
For reference, the 6-bottle bundle currently brings the cost down significantly per bottle compared to purchasing individually, which is why many customers choose that option to maintain their immune support routine throughout the year.
Most importantly, we truly appreciate your continued trust in BioShield MD over the past several years. Supporting your immune health consistently over time is where supplements like this can make the biggest difference, and we’re honored to be part of your daily wellness routine.
If there’s ever anything we can do to make your experience easier, whether that’s helping with the website, reviewing your order options, or answering questions, our team would be more than happy to help.
Thank you again for being part of the BioShield MD community. Your feedback truly helps us continue improving while supporting customers like you on their journey toward stronger everyday wellness.
