The Plant Stem Cell Serum with Peptides + Plant Derived Exosomes

This upgraded formula combines our signature peptide complex with plant stem cell extracts, hyaluronic acid, coenzyme Q10, Edelweiss stem cells, Kakadu plum, and plant-derived exosomes rich in botanical antioxidants, polyphenols, naturally occurring enzymes, and protective plant lipids.

Rather than chasing quick fixes or aggressive correction, this serum helps support healthier-looking skin by improving hydration, reinforcing the skin barrier, and promoting overall skin resilience over time.

Suitable for virtually every skin type, including sensitive, dehydrated, and acne-prone skin.

Why Plant-Derived Exosomes?

At BIBA LOS ANGELES, we're always looking for meaningful ways to improve our formulas. When plant-derived exosomes became available, they were the perfect complement to our Plant Stem Cell Serum, adding another layer of botanical support without changing the lightweight feel clients love.

WHY THIS PEPTIDE SERUM WORKS DIFFERENTLY

This formula was carefully refined over many years while treating thousands of clients. Every change was guided by one simple question: How did the skin respond?

Many serums are formulated to aggressively correct skin concerns. While active ingredients certainly have their place, skin doesn't always thrive when it's constantly being pushed. That philosophy shaped this serum from the very beginning. Over the years, one thing became clear: skin tells you very quickly what it likes, and what it doesn't. This serum evolved by listening to those responses. Every refinement was made because it improved how the skin responded to the formula.

HYDRATION SUPPORT AND ROUTINE STABILITY

Hydration remains at the heart of this formula.

Well-hydrated skin is better able to maintain a healthy barrier, tolerate active ingredients, stays bright and recovers well from daily environmental stress.

For best results, apply the Plant Stem Cell Serum after the Hydrating Toner. The toner helps replenish water immediately after cleansing, while the serum helps maintain hydration and supports the skin barrier throughout the day or night.

The Plant Stem Cell Serum layers effortlessly beneath moisturizers, sunscreen, vitamin C, retinoids, niacinamide, and exfoliating acids, making it an ideal daily support serum for nearly every routine.

If your skin frequently feels dehydrated, reactive, tight, or inconsistent after using active ingredients, this serum helps restore hydration while supporting overall skin balance.

We typically don't recommend layering serums. Instead, think of them as complementing each other, Meta C Serum in the morning for antioxidant protection, and Plant Stem Cell Serum at night to replenish hydration and support the skin.

DEVELOPED FROM REAL TREATMENT ROOM EXPERIENCE

Created by celebrity esthetician Biba de Sousa after decades of treating acne-prone, reactive, and compromised skin, this serum reflects a philosophy developed through thousands of professional treatments.

Over the years, one pattern became clear: many skin concerns weren't caused by a lack of active ingredients, they were caused by skin that had lost its ability to function optimally.

This serum was designed to become the stabilizing step in virtually any routine, a daily layer that supports hydration, reinforces the skin barrier, and helps skin remain resilient even when using corrective products.

It's often the product clients reach for when their skin simply needs to feel healthy again.
