COMPANY REVIEW
Sun Coast Sciences Reviews (2026): Is the Company Behind Total Package Serum Legit?
Sun Coast Sciences sells Total Package Serum and a long list of supplements and skincare. Here's who the company is, how to reach it, what its refund policy really says, and how to check complaints yourself before you buy.
Sun Coast Sciences is a real direct-to-consumer company, Sun Coast Sciences, LLC, that sells Total Package Serum along with a long list of supplements and skincare products through its own store and Amazon. It publishes a customer service phone number, a text line, an email address, a return address and a refund policy, which is what separates a real company from a disappearing storefront. It is also a company with aggressive advertising, which is why shoppers search for its reviews and complaints before they order.
This page is about the company, not just the serum. It covers who Sun Coast Sciences is, what it sells, the price and refund details we could verify on its own store, how to contact it, and how to check its complaints yourself. For the product, read our Total Package Serum review; for the buying details, see where to buy Total Package Serum. TopCrate earns a commission when readers buy Total Package Serum through our links, which doesn't change what we report here.
Sun Coast Sciences at a glance
Company: Sun Coast Sciences, LLC, which operates the store at store.suncoastsciences.com and the brand site suncoastsciences.com. Its products are also listed on Amazon.
Customer care: the store lists 1-888-281-6816 (8am to 8pm Central, daily), a text line at 1-561-232-3612, an email address at mail@suncoastsciences.com and a live chat. Those details appear on the store's contact page and in its footer.
Shipping: the store advertises free shipping on orders over $50. Returns are sent to a fulfillment warehouse in Hebron, Kentucky, according to its refund policy.
Advertising: the store's pages carry a notice that the views and opinions of Dr. Mark Rosenberg do not necessarily represent those of the organizations he is or was associated with, and that the statements on the site have not been evaluated by the FDA. More on what that means below.
What Sun Coast Sciences sells
The store is a broad catalog, not a one-product shop. Its listings include supplements with names like BioShield MD, AccuThink, Active Gut Complete and AMPAlive, and skincare such as Total Package Serum, BioLuna, an anti-aging face mask and a 24k bubble mask, along with multi-product bundles.
Total Package Serum is its best-known skincare product: a 1 fl oz all-in-one serum that combines a vitamin C derivative, hyaluronic acid and tri-peptides. That's the product we review on TopCrate. We haven't reviewed the company's supplements, so nothing on this page is an opinion on them, and supplement claims deserve their own independent scrutiny.
Total Package Serum prices from Sun Coast Sciences
On the company's own store when we checked on September 30, 2026, Total Package Serum was listed at $49.95 for one bottle (shown against a $120 regular price), $86 for two, $117 for three and $198 for six. The promotional checkout we link to presents it differently: $49 a bottle plus $4.95 shipping, $43 each for two bottles with free shipping, with a "subscribe and save" option at 10% off.
The "regular price" of $120 is the company's own reference number; the discounted price is the one people actually pay. Treat the savings percentages on any promotional page as marketing, and compare the final total at checkout, including shipping and any subscription setting.
If you're also weighing the serum against another vitamin C option, our Total Package Serum vs Vibriance comparison lays out price, ingredients and guarantees side by side.
The Sun Coast Sciences refund policy, in plain English
The store's refund policy tells you to request an RMA (return authorization), ship the package to its warehouse, and notes that Sun Coast Sciences does not cover return shipping. It says it issues the refund once the return is received and processed at the warehouse, which can take up to two weeks, and that the credit then takes three to five business days to appear on your account.
The promotional checkout for Total Package Serum advertises a longer guarantee, a 365-day money-back guarantee. The two documents are not the same thing, so read the guarantee terms shown at your checkout, screenshot them, and keep the order confirmation. If you buy on Amazon instead, Amazon's return process applies, not the company's.
Practical rule: whichever route you buy through, note the date you placed the order, keep the packaging and tracking number, and start any return by phone or email before you ship anything back.
Who is Dr. Rosenberg, and what do the disclaimers mean?
Sun Coast Sciences' marketing is associated with a Dr. Mark Rosenberg; its Amazon listing for the serum names him too. The store's own footer carries a disclaimer that his views and opinions don't necessarily represent those of the organizations he is currently or formerly associated with. We couldn't verify his credentials or his role at the company from the store pages, so we don't rely on his name as evidence of anything.
That is worth keeping in mind with any doctor-fronted ad: a "Dr." in the name of a pitch is not a clinical study. The FDA notice on the site is standard for cosmetics and supplements and simply means the claims haven't been reviewed by the agency. For a cosmetic like a face serum, reasonable expectations are smoother-looking, better-hydrated skin over weeks, not a reversal of aging.
How to check Sun Coast Sciences reviews and complaints yourself
We're not going to quote star ratings here, because they change, and because we couldn't load some review sites automatically. Instead, check three places before you buy and look at the newest reviews first.
Trustpilot and the Better Business Bureau: look for how the company responds to complaints, and for recurring themes such as surprise subscription charges, slow refunds or shipping delays. Amazon reviews of the product: read the recent three- and four-star reviews, which tend to be the most specific. The company's own help pages and phone line: call or text the number above with a simple question and see how quickly you get an answer.
One complaint pattern is common with promotional checkouts in general: customers who didn't notice a subscribe-and-save setting or a bundled add-on. Uncheck anything you didn't choose on purpose, and choose a one-time purchase if you don't want recurring shipments.
Sun Coast Sciences vs the alternatives
Sun Coast Sciences is priced above a drugstore vitamin C serum and below many department-store ones. If you want to keep the routine simple and inexpensive, a fragrance-free drugstore vitamin C plus a separate moisturizer is a sensible baseline. What the company sells is convenience, a single bottle that combines several steps, and a guarantee window you can use if you keep your paperwork.
If you'd rather see the two bottles compared directly, the closest rival people search for is Vibriance; our side-by-side covers it. And if you only want the plain answer to "is it legit," our Is Total Package Serum legit? guide goes through the funnel step by step.
Our verdict on Sun Coast Sciences
Sun Coast Sciences is a real company with real contact details, a published refund policy and a store that matches its listings. It is also an aggressive marketer, with a doctor-fronted pitch, large "regular price" discounts and a checkout that nudges you toward bundles and subscriptions. None of that makes Total Package Serum a scam, but it does mean you should buy deliberately: verify the final total, pick one-time or subscription on purpose, and keep your order confirmation.
If a serum that combines vitamin C, hyaluronic acid and peptides appeals to you, Total Package Serum is a reasonable product from a real company; just don't expect the before-and-after promises in the ads. Anything about persistent skin problems belongs with a dermatologist.
