If you’ve been comparing “Del Mar Total Package Serum” against another Total Package Serum, you’re probably looking at two different products that share one name. One is from Del Mar Laboratories, the other from Sun Coast Sciences, and almost no page spells out the difference, so mixing them up is easy.
They look alike on purpose. Both are 30 mL anti-aging serums that stack Vitamin C, hyaluronic acid, and peptides, both are sold direct to consumers, and both carry the exact name Total Package Serum. So before you buy, it’s worth knowing which one is in your cart.
For this guide we read both companies’ product pages, their return policies, and their public business records. We didn’t apply either serum. Here’s how to tell them apart, and which one we’d point you to.
Two different companies, one product name
The quickest way to keep them straight is by the maker. They’re genuinely separate businesses that happen to have landed on the same product name.
Del Mar Laboratories is a San Diego company founded by Dr. Paul Chasan, a board-certified plastic surgeon. Its Total Package Serum is a 30 mL Vitamin C, hyaluronic acid, and peptide serum, and the company holds an A+ BBB rating. It sells through its own store with a 90-day guarantee.
Sun Coast Sciences is a Miami Beach company, and its Total Package Serum was formulated by founder Dr. Mark Rosenberg, M.D. It’s also a 30 mL Vitamin C, hyaluronic acid, and peptide serum, sold through the official store and on Amazon, and it’s backed by a 365-day money-back guarantee.
We looked for a corporate link between the two and found none: different founders, different cities, different guarantees. So the honest answer to “are they the same?” is no. They’re rivals that share a name, which is exactly why the search results feel so tangled.
How to tell which one you’re looking at
The formulas are strikingly similar, so don’t rely on the ingredient list alone. Check three things instead.
The brand name on the label. Sun Coast Sciences or Del Mar Laboratories, printed near the product name, is the clearest tell.
The founder and city. Dr. Mark Rosenberg and Miami Beach points to Sun Coast. Dr. Paul Chasan and San Diego points to Del Mar.
The guarantee. A 365-day promise is the Sun Coast version. A 90-day promise is Del Mar. That single detail sorts most orders.
One thing both share: neither is sold at Target, Ulta, or Sephora. If a listing claims a shelf presence at a big retailer, treat it with caution. Our where to buy Total Package Serum guide covers the legitimate places to order the Sun Coast serum and the tiers that save money.
Which one we’d buy, and why
Both are real, legitimate serums, so this comes down to the details. We land on the Sun Coast Sciences Total Package Serum for two concrete reasons.
First, the 365-day money-back guarantee is four times longer than Del Mar’s 90-day window, which is a real safety net for a serum you need weeks to judge. Second, it has the broader public review base, averaging about 3.8 stars across roughly 1,200 Amazon reviews plus a 4.1 Trustpilot score for the seller, so there’s more independent feedback to read before you commit.
