Been using Karam Trifecta products for over a year as routine. Also do self-microneedling, get facials too. Quench serum is soothing post-washing with Rinse product. Added Polish to routine (during showers). Some people comment on how good my facial skin looks at 62. Pricey but I’m worth it ;-)

I’ve used Quench and Illuminate for about 1 1/2 years now. What is promised happens. I’ve used many many different products in all price ranges and never found something that works as well as this or is so simple to use. Much better skin quality, decreased pore size, reduced wrinkles, better firmness, faded sun spots.
