Bought and used several skin products for several months with No results. the dark spot remover actually intensified the spot! It's a rip off-the doctor appears very sincere, but nothing works!!
Response from Sun Coast Sciences LLCDec 22, 2025
Hi Meg, Thank you for sharing your experience. We’re truly sorry to hear how disappointed you feel, especially after giving the products several months of consistent use. We understand how frustrating that can be.
Skin can respond very differently from person to person, and in some cases changes—especially with dark spots—can temporarily appear more noticeable as the skin goes through a renewal process. That said, we never want anyone to feel discouraged or stuck with products that aren’t right for them. This is exactly why we stand firmly behind our 365-day guarantee.
Dr. Rosenberg genuinely cares about results, which is why education and realistic expectations are so important to us—but when something doesn’t work as hoped, our priority is supporting the customer. If you haven’t already, we’d truly like the opportunity to review your experience, help troubleshoot, or assist with a return and refund.
Our Customer Happiness team is available 24/7, and you can get immediate help or start the return process anytime through our self-service portal at help.suncoastsciences.com. We’d really appreciate the chance to make this right and earn back your trust.

Thank you for sharing your experience. We’re genuinely sorry to hear you didn’t see the results you were hoping for, and we understand how disappointing that can feel.
We want to reassure you that Sun Coast Sciences is absolutely not a scam. Our products are formulated with clinically studied ingredients, but results can vary from person to person based on factors like skin type, age, consistency of use, and overall routine. Many customers see gradual improvements over time rather than dramatic changes in the first few weeks.
That said, every order is backed by our 365-day guarantee. If you aren't satisfied, we encourage you to reach out so we can troubleshoot, offer guidance, or arrange a refund. Our customer happiness team is always here to help and is committed to making things right.
We’re disappointed we didn’t have the chance to connect with you directly, but we truly value transparency and the opportunity to earn trust through real support and real solutions.

Skin salt and auto renew? Not me
I purchased 3 containers of skin salt, I thought it would as my skin is dry and flaky, I took it every day and my skin is still flakey but I didn't try to get a refund. Over a month passed a finished the last container and all of a sudden, today they tried to charge my bank, I did not sign up for a subscription and I haven't gotten anymore product so why are they charging me? I haven't got a response as yet.

First, regarding results: we understand how disappointing it is when a product doesn’t deliver the improvement you hoped for. Every order is backed by our 365-day guarantee, and our team is always happy to help with troubleshooting or refunds.
As for the charge you’re seeing, we want to reassure you that we do not charge customers without an active subscription. Sometimes a subscription is selected at checkout for added savings, and if it isn’t canceled, a future shipment can be scheduled. That said, it is never our intention to surprise anyone.
Our Customer Happiness team is available 24/7 to quickly review the account, stop any future charges, and issue a refund if applicable so please don't hesitate to reach -- just visit our support page at suncoastsciences.com for immediate assistance.
We’re disappointed we haven’t connected with you yet, but we absolutely want to make this right and earn your trust. Please know support is always available, and helping customers feel confident and cared for is our top priority.

SunCoast SCAM/SPAM Company
SunCoast is nothing more than a SCAM/SPAM company. I ordered 1 month supply of the DHT hair growth product. Which took diligent "NO" answers on the website. Beyond their repeated attempts to order 3-6 months of the product, that cost $50 per bottle. It took forever to get the ordered product delivered, after the order was accepted. Upon delivery, I took the pill as directed, for 30 days, and found no improvement for the sheding or fallout of my hair. This company is a SCAM! Don't order anthing from them.

Thank you for taking the time to share your experience, Sheila. We’re truly sorry for the frustration you felt, and we appreciate the opportunity to provide a little clarity for you.
When it comes to results, hair and wellness supplements typically work gradually. Hair growth follows a natural cycle, and many customers who see improvement do so with consistent use over several months. We understand how discouraging it can feel when results aren’t noticeable right away, which is why every purchase is protected by our 365-day guarantee—so customers never feel stuck if a product isn’t right for them.
During checkout, we do offer multi-month options because many customers prefer the added savings, but single-bottle purchases are always available. Subscriptions can be managed or canceled at any time, often instantly, through our self-service tools or with help from our team. Our goal is always clarity, never pressure.
We’re disappointed we didn’t have the chance to connect with you directly, as we would have been happy to help review your order, discuss options, or issue a refund if appropriate. Support is available 24/7, and we encourage anyone with questions or concerns to visit the support page on suncoastsciences.com for immediate assistance.
We truly value transparency, stand behind our products, and remain committed to supporting every customer with care and respect.

Disappointed in the Product &the Return Process
When I purchased the products I decided to order a 12 month supply, due to expected "supply chain shortages" and "small batch production". I received the products and used them faithfully day and night. The cleanser had a slight burning sensation. But in 2 months of product use, I see no discernable difference with my complexion.
In addtion to already having a 12 month supply, I did not realize I was automatically enrolled in a monthly subscription so additional product was being sent.
When I called to request a return I was "firmly" told I am responsible to pay for shipping for unused and used bottles. So I encur a higher penalty for return expense due to the extra product received via subscription.
Customer service was not 5 star, either. No compassion about having tried it and not working for me. I spoke to her in July.
Today, August 12th, I went into the website to print out return authorization and noted she did not arrange for ALL my product to be returned.

Thank you for taking the time to share your experience Leann. We’re truly sorry for the disappointment and frustration you felt, both with the product results and with how the return process went. We appreciate you giving us the opportunity to listen and clarify.
We understand how discouraging it can be to use a product consistently—day and night—and not see the improvement you were hoping for. Everyone’s skin responds differently, and sensations like mild tingling or warmth can occur depending on skin sensitivity. This is exactly why we offer a 365-day guarantee, so customers have plenty of time to try the products and reach out if something doesn’t feel right or isn’t meeting expectations.
Regarding subscriptions, we want to be very clear and transparent. Subscription options are always optional and offered only for additional savings. Customers must actively opt in during checkout, and we fully comply with all consumer protection requirements—subscriptions are never forced. That said, we’re truly sorry for any confusion, and our team is always happy to review an account, explain how it was set up, and stop any future shipments immediately if needed.
For returns, customers are responsible for return shipping, which is standard in our industry, but we never want that to feel like a burden—especially after making a thoughtful commitment to try the product. We’re disappointed to hear that your interaction with our team felt lacking in compassion or that the return authorization didn’t include all eligible items. That’s not the experience we want for anyone.
We would genuinely appreciate the chance to review your account, correct any oversights, and help bring this to a smooth and fair resolution. Support is available 24/7, and we encourage you to visit the support page on suncoastsciences.com for immediate assistance.
Your feedback matters to us, and we remain committed to transparency, care, and earning trust every step of the way.

I have been using it morning and night…
I have been using it morning and night and notice no visible results after over a month. A total waste of time and money. Wish I would have read all the reviews before ordering any of it.

Thank you for sharing your experience. We’re truly sorry to hear how disappointed you feel, and we understand how frustrating it can be to commit time and consistency without seeing the results you hoped for.
Skincare results can vary widely from person to person, and for many people, visible improvements happen gradually over a longer period of use rather than within the first few weeks. That’s exactly why every purchase is protected by our 365-day guarantee, so customers have plenty of time to try the product.
We’re disappointed we didn’t have the opportunity to support you sooner. Please know, our Customer Happiness team is always here to help with product guidance, troubleshooting, or a refund if the product isn’t right for you. Support is available 24/7, and we encourage you to visit the support page on suncoastsciences.com for immediate assistance.
We truly value feedback and would appreciate the chance to earn your trust and make this right.

This company engages in shady marketing.
This company engages in affiliate marketing that is nothing less than spamming. If their product was any good then they wouldn't have to resort to this sort of annoying tactic.
Response from Sun Coast Sciences LLCDec 19, 2025
Thank you for sharing your perspective. We understand that receiving marketing emails isn’t for everyone, and we never mean for our messages to feel intrusive.
Many of our emails come directly from Dr. Rosenberg, who shares educational information because he genuinely cares about helping customers get the best possible results. Customers are always free to unsubscribe at any time, though doing so may mean missing out on his insights as well as occasional savings on our products.
That said, the frequency of emails doesn’t reflect the effectiveness of our products. We stand behind every purchase with a 365-day guarantee and offer real, 24/7 customer support to assist with questions, results, or service whenever needed.
If you need help managing email preferences or need support please visit the support page on suncoastsciences.com for immediate assistance.
