It's been at least 6 weeks since I began using all four staple products in the regimen. The essence is my favorite. My skin feels better. I am tired of the retinoid barrier damage and repair cycle. Regelica solves this drama. When I use all four products consistently my skin looks more plump, hydrated, healthy and even. I'm not trying to look 20, I'm aiming for amazing looking skin that I treat with respect and solid ingredients. Friends and co-workers ask me if I have a new man in my life. Nope, I have better skin care, which is much more reliable. Regelica is a game changer.
