- CLCatherine L.Verified BuyerWhat are your skin concerns? Fine Lines & Wrinkles, Uneven Skin Tone / DiscolorationYesterdayWhat are your skin concerns? Fine Lines & Wrinkles, Uneven Skin Tone / DiscolorationRated 5 out of 5 starsVery pleased!
I have been using Dr. Karam’s Trifecta for a few months now. I love the simplicity of just three simple steps in the morning and the same three simple steps before bed. My skin appears smoother and brighter. I’ve even convinced my husband to start using it, and he’s never used a skincare regime in his entire life! I’m a fan!
KSKaramMD Skin33 seconds agoHi Catherine! We love hearing how easily Trifecta has become part of your daily routine, and it makes us so happy that your husband has joined you, too! Thank you for sharing your experience with us. 💛

Uneven Skin Tone / Discoloration, Environmental Damage, Skin Texture, General AgingRated 2 out of 5 starsContainer/packaging malfunction
The container pump malfunctions and won’t pump out the vitamin C. The vitamin C tends to harden at the tip and gets plugged if that makes sense. This is my 4th cycle of purchasing it but if continues to be an inconvenience, I will stop my subscription. For the price we pay, the container should dispense smoothly and continuously.
KSKaramMD Skin4 days agoHi Cris,
Thank you so much for taking the time to share this, and we're truly sorry to hear about the pump malfunction you've been experiencing. We completely understand how frustrating this must be, especially after multiple purchases and with the investment you're making in your skincare routine. A dispenser that doesn't work smoothly is definitely not the experience we want for you.
We take packaging issues like this very seriously, and we'd love the chance to help make this right. Please reach out to us directly at customerservice@karammdskin.com so we can address this with you and find a solution. We're always happy to help with any concerns you have.

At 68 years old, I finally found the skincare system that I have been waiting for. After spending countless time, effort, and a lot of money purchasing skincare lines that never did what they promised to do, KaramMD Trifecta has made all the difference in the world. I thought it might be too late for me at my age, but after three months, I’m seeing a positive difference. No more searching for the right skincare system because Trifecta checks all the boxes related to my expectations, including exemplary customer service.
