Lack of sleep, chronic stress, and environmental pollution — these overlapping external burdens push the skin into a state of "skin burnout¹." Dullness, fine lines, puffiness, and redness all trace back to burnout at the cellular level: when the connections between cells are disrupted, the exosomes that carry recovery signals lose their effectiveness, and the skin's condition falls out of balance.
The new [EXO] stem cells³ combine conventional stem cells with "elicited" stem cells — cells whose defensive and recovery power has been further strengthened through exposure to stress — to awaken cell-to-cell communication and activate the skin's recovery mechanisms.
With the awakening power of 1 billion [EXO] stem cells², the serum addresses the many causes of skin burnout¹ from multiple angles. A peptide⁴ that works directly on exosome production, together with niacinamide⁵ that supports barrier function, draws out the skin's underlying strength even further.
Helena Rubinstein's P.C. Skinmunity EXO Serum is designed to help skin overcome burnout¹ in today's demanding world and reveal a radiant, smooth, youthful-looking complexion. It launches nationwide across Japan on Friday, August 7, 2026.
An Advanced Partnership and the Sixth-Generation Serum
Since its founding in 1902, Helena Rubinstein has led beauty innovation under founder Madame Helena Rubinstein's belief that "there is no beauty without science." Since 2010, the brand has drawn on the potential of plant stem cells as a starting point for its research, continually evolving its iconic P.C. Skinmunity line. Now, the sixth generation of the series' core serum arrives.
In developing this product, Helena Rubinstein formed a new partnership with Dr. Hong, founder of Clinique HUS,HU, a clinic leading regenerative dermatology in Korea. By combining his advanced expertise with the brand's own skincare formulation know-how, the collaboration further strengthened Helena Rubinstein's cell-to-cell communication research and established a new model of high-performance skincare.
"Skin Burnout": A Challenge for Today's Generation
For today's multitasking, always-busy generation, external factors such as irregular sleep cycles, stress, and air pollution place a burden on the skin's natural ability to maintain balance and recover, leading to dullness, dry fine lines, redness, and puffiness — collectively described as "skin burnout¹."
Helena Rubinstein focused on this skin condition, supporting cell-to-cell signal transmission to guide skin toward a resilient, youthful-looking appearance that radiates strength from within, undeterred by harsh environments.
New Technology: The Proprietary [EXO] SAM™ Technology
Focusing on cell signal transmission in a state of skin burnout¹, this innovative technology was developed to support the skin's recovery, conditioning, and barrier function.
[EXO] Stem Cells³ (Main Ingredient)
Extracted from a rare halophyte plant known as "オセアニック クリスタ," found along the Emerald Coast of France's Brittany region. In addition to conventional stem cells, the formula newly incorporates "elicited" (stress-stimulated) stem cells, whose defensive and recovery power has been strengthened by exposure to harsh stress conditions, establishing a dual-mode technology. With more than 1 billion² plant-derived exosome-like nanovesicles per pump, the serum penetrates quickly into the stratum corneum.
Proteasyl Peptide⁴
Supports the skin's natural renewal process and provides a supple sense of firmness.
Vitamin C Derivative⁶ & Niacinamide⁵
Protects the skin from external irritants and helps maintain a strong skin barrier.
An Exceptional Texture and Refined Fragrance
The moment the moisture-rich gel touches the skin, it transforms into a light essence and penetrates instantly⁷. Ultra-fine pearl particles give the skin a beautiful radiance, leaving a light, comfortable feel without stickiness.
A fresh floral fragrance with a green impression brings a moment of soothing comfort to your daily skincare routine.
