FOCUSED SUPPORT FOR MID-AGE TRANSITION

Reset the Balance as Initial Structural Changes Begin

As the skin enters its mid-age phase, oxidative stress intensifies and collagen renewal begins to slow, leading to the first visible decline in tone, firmness, and hydration. The Skin-Aging Reset Bundle targets this critical stage, reinforcing antioxidant defense, strengthening collagen support, and restoring hydration balance to maintain the skin’s natural resilience. With consistent use, it helps stabilize mid-age changes and visibly preserve youthful tone, texture, and radiance.

Legendary Power through Science

How It Works

At the heart of this system is the GTA™ (Golden Triple Actives) complex, formulated to reinforce antioxidant defense and maintain essential hydration as mid-age skin begins to show increased environmental vulnerability. This period often introduces early firmness decline and stronger oxidative stress; the bundle helps stabilize these shifts. Together with niacinamide, peptides, and botanical antioxidants, the system helps reduce harmful ROS, enhance moisture retention, and maintain the skin’s natural self-repair processes. Ideal for individuals within the 45-49 age range who are experiencing the first meaningful structural changes.

A noticeable firmness boost

The routine is super easy: cleanse, serum, lotion, then cream at night. My skin feels supported without being greasy. This bundle honestly feels made for this age range.

Karen D
Helped calm my mid-40s dryness
☆ ☆ ☆ ☆ ☆

My skin gets dry in random patches now that I’m 47. The cleanser is gentle and doesn’t leave my face tight. The serum + lotion combo really balanced things out.

Julia R.
Exactly what my 40s skin needed

I didn’t realize how much oxidative stress was affecting my skin until I tried this system.  After a few weeks my skin looked healthier, more hydrated, and just… revived. I’m sticking with this bundle.
