Common questions.

What does this replace in my routine?

Your serum, moisturizer, and other active serum products in your routine, such as retinol, peptide serums, niacinamide serums etc. Your cleanser stays. Your sunscreen stays (in the morning). Most of our users drop 2–3 products from their nighttime routine within the first month.

When will I see results?

Most users notice visible improvements, such as smoother texture, improved radiance, within 2 weeks of use. Firmer skin and reduced fine lines typically follow by week 6.

Can I use it with retinol or vitamin C?

Yes. While you wouldn't need Retinol at the same time (since L-01™ produces similar pathway effects), it will not be harmful. Using Vitamin C in the daytime supplements antioxidant effect.

Is it safe for sensitive skin?

Yes, Longevity Protocol is formulated to be soothing and reparative, and tested to be free of irritants, harsh alcohols, allergens, and eczema triggers.

What growth factors are used in L-01™ and how do they benefit the skin?

EGF, FGF-2, and IGF-1. Together they make up a biologically accurate profile of what stem cells secrete to stimulate collagen and elastin production, alongside fibroblast proliferation. This results in visibly firmer, thicker, more resilient skin that has capacity to repair itself against intrinsic and extrinsic damage.

At what age should I start using Longevity Protocol?

Ideally in your mid-20s, but Longevity Protocol is beneficial to all age groups in supporting existing damage repair and preventing further visible aging.
