My skin is very smooth and soft. Lines appear diminished and less visible. It has a nice glow.

Cared and were patient to find out my concerns. They also helped me figure out different scenarios that could have happened in regards to my timing by checking my order and delivery etc. Anyway it worked, and the company rep, offered to resend my order if I couldn't find it. Which rarely happens.

I just happened to see a video online for the Total Package Serum and I was amazed by the results of the women in the video. I am 72 years old and I was anxious to try it to see if I would notice a difference in my wrinkles on my face and neck. I ordered several bottles of the serum and was excited to see what the results would be for me. I have only been using the product for a week and really could not see a difference when I looked in the mirror. I had a male friend ask me to send him a picture of myself since it had been a while since we had exchanged photos of each other. I took a selfie and sent it to him and was shocked when he commented that I looked absolutely stunning. I went back and took a good hard look at the photo that I had sent him and was shocked to see that my skin looked flawless in the photo and I looked a lot younger than my 72 years. I think that the result is because of my having used the new serum. I did not expect to see the results so soon, but I am so pleased with this serum and I don't want to be without it now.

Customer service here is great! I had a small “hiccup”in my order and it was handled so professionally to my fullest satisfaction. I spoke with Rolyn and couldn’t have been happier with the outcome. I love the product as well.

I bought total package serum by sun coast science and like most products I try, I am hoping it’s the real deal and not a waist of money, this product really worked! two weeks of applying twice a day I noticed smother skin and better over all complexion. I am on my third bottle and think it is the real deal!

I’ve used it for two days am and pm as instructed. I am pleasantly surprised how the crepe of my skin has improved already. The lines in my forehead have lessened. I can’t wait to see how I look in a week I took a picture on the day I started and I’ll take a picture every week going forward
Response from Sun Coast Sciences LLCMay 11, 2026
