So far, so good! I was already using a different serum, but yours goes on much smoother and "silkier". I'm definitely watching my skin for results that may be a bit better than my last serum, which I actually found to be pretty adequate, but with room for improvement. I'm liking my "Total Package Serum" so far.
Response from Sun Coast Sciences LLC· Sep 5, 2026
We love hearing that you’re enjoying the silky, smooth feel of Total Package Serum! It’s especially great to know you’re coming from another serum you already liked and are giving ours a chance to take things a step further. We’re excited to hear what you think as you continue using it!

I just started this 4 days ago but before I got it in they made sure to have someone go over a lot with you. I really have not been using it long enough to say anything else. I do love the fragrance of it.
Response from Sun Coast Sciences LLC· Sep 5, 2026
Thank you for giving Total Package Serum a try! Four days is definitely still early, but we’re so glad you’re enjoying the fragrance already. We hope you continue loving how it feels on your skin as you give it more time!

Buyer 5 Star Reviews "I’ve been using Total Package Serum for about 2 years. I love the way it makes my skin feel, and how at 52 yrs old, everyone thinks I’m in my 30’s. I will continue to use this, and recommend to family and friends. Thank you Dr. Mark Rosenberg for developing such a great product!"
Response from Sun Coast Sciences LLC· Aug 29, 2026
Wow, we absolutely love hearing this! Two years of consistency is amazing, and it’s wonderful to know you love how your skin feels. And being told you look like you’re in your 30s at 52? That’s quite the compliment! Thank you so much for your continued support and for recommending Total Package Serum to your family and friends. We’ll be sure to pass your kind words along to Dr. Rosenberg!
