I have been using Trifecta, Polish and Enrich for about 16 months now.
My skin has never looked better, and people frequently comment on my skin, including the aesthetician, who comments on it every time I see her.
Even better, I haven’t had a single issue ever since I started. No redness, no discomfort, no sensitivity. I can handle the tropical heat, the daily swim in the salty ocean. Even when I overheat from doing heavy gardening in the tropics and I overheat, my skin returns to normal as soon as I cool down.
I love this skin care.
I love the results, I love my skin again and I feel more confident. I enjoy how the products apply, how clean feeling they are, how they smell, how they feel on my skin, and how my skin never feels dehydrated any more. What a joy.
I so, so appreciate having to apply fewer products, no waiting time between products, taking less time to apply skincare, etc, etc. And, I really enjoy the packaging. I have never seen a dispenser so attractive and so practical. Nothing protruding, nothing taking up extra heights and it is impossible to spill. Beautiful and ingenious.
If this much thought has gone into the packaging, how much thought must have gone into the products.? Someone truly cares, on all levels. Thank you, Dr. Karam!
If I may say one tiny thing, that could possibly be improved, unless it is due to the climate I live in or the heat of our home during the day, it is this. Quench, and only Quench, crystallized…

General Aging, Uneven Skin Tone / Discoloration, Fine Lines & WrinklesRated 5 out of 5 starsWas a non believer till I started the regiment
I’m a 44-year-old male who really had not been regularly taking care of the skin on my face. I just assumed whatever damage I’ve accumulated through the years was unfixable. My wife got me the trifecta as a gift and told me I had to at least run the program for a couple months to at give it a shot. I gave it a try and I’m noticing significant changes. My skin is much more refreshed, I don’t look as tired in the face, I feel visibly younger. I’m very shocked that this worked so I plan on continuing to use this product as I am now a believer! I guess it never is too late!
KSKaramMD Skin1 week agoFrom non believer to believer, we absolutely love this journey for you! It's amazing what a couple months of consistency can do, and hearing that you look more refreshed, less tired, and visibly younger is exactly the kind of transformation we hope for. Your wife clearly knew what she was doing with that gift! Thank you for giving it an honest shot and for sharing your story, it truly never is too late. ☺️
