Frequently Asked Questions

What's inside Consortia Factors®?

A rich, plant-cell-derived secretome — naturally occurring plant exosomes, peptides and glycoproteins, antioxidant metabolites (including vitamin C), and skin-mimetic lipids — that together signal across multiple renewal pathways.

How does the ReGenerative Serum work?

Its bio-intelligent ingredients — Consortia Factors®, with its plant exosomes, peptides, and metabolites — "speak" your skin's cellular language, helping activate its own renewal pathways. Biomimetic lipids reinforce the barrier and antioxidants neutralize free radicals, so skin restores itself rather than being forced by a single harsh active.

When will I see results?

Many people notice improved hydration, texture, and glow within 1–2 weeks, with firmer skin, softer fine lines, and more even tone typically emerging at 4–6 weeks. Results are cumulative and build with consistent use.

Is it safe for sensitive skin?

Yes — it's formulated for sensitive skin: plant-based, biocompatible, and free of parabens, sulfates, phthalates, drying alcohols, and silicones. The lightweight, non-comedogenic texture absorbs without clogging pores. As always, patch-test if you have a history of reactivity.

What concerns does it address?

Fine lines and wrinkles, uneven tone and discoloration, rough or dull texture, loss of elasticity or firmness, dryness or sensitivity, and overall skin imbalance.

How is it different from other medical-grade serums?

Our cell-to-bottle™ process and proprietary Consortia Factors® technology. We control every step — from cultivating cells in our FDA-registered, cGMP-certified lab to formulating and bottling in-house — so actives reach you at full purity and potency.
