Nationwide release from July 20, 2026

Global prestige skincare brand SK-II is launching the serum "Facial Treatment Serum" from its Facial Treatment series.

"Facial Treatment Serum" will be available nationwide at SK-II counters and online stores from July 20, 2026.

New Scientific Insight: Quantifying the Relationship Between Stress and Skin

SK-II conducted its own research on the relationship between stress and skin age. The results revealed that most factors contributing to skin aging are not caused by genetic elements or age-related changes, but by stress from lifestyle habits. It was found that life stress affects the expression of 701 genes. Furthermore, SK-II re-examined the relationship between stress and skin aging and acquired data. This showed that high stress can lead to skin age increases of +1.8 years for those in their 20s to early 30s, and +5.5 years for those in their late 30s to 40s.

Accumulated stress leads to skin age > chronological age.

Contains Concentrated PITERATM*6 and Micro Oil Beads

"Facial Treatment Serum" is a rich serum formulated with SK-II's proprietary Concentrated PITERA*6 and newly developed Micro Oil Beads*3 with a particle size of approximately 0.7mm achieved through microfluidic technology. Its unique texture, a rich jelly-like consistency, spreads refreshingly upon application, instantly imparting radiance. It also features a woody floral scent inspired by the rare Mizunara oak from Japan.

- Concentrated PITERA: A naturally derived ingredient containing over 50 components, including vitamins, amino acids, minerals, and organic acids, that maintains the skin's natural health.

- Micro Oil Beads: The Micro Oil Beads*3 themselves are beauty ingredients. Since the beads are not enclosed in a hard shell, the beauty ingredients blend into the skin as they dissolve, providing a non-sticky, residue-free feel. A 50ml bottle of serum contains approximately 16,000 Micro Oil Beads*3.

- Mizunara Scent: A sophisticated woody floral scent inspired by the Mizunara oak, sometimes used for aging fine whiskies. This is the first scent for an SK-II product.

An Icon Symbolizing SK-II's Craftsmanship

"Facial Treatment Serum" reflects the brand's commitment to craftsmanship. The characteristic locking sound when closing the bottle and the padlock-inspired packaging design express the concept of "locking in beauty." The texture has also been meticulously crafted. As the rich, jelly-like texture envelops the skin with moisture, the beauty ingredients condensed in the Micro Oil Beads*3 burst and penetrate*7, leading to soft, hydrated skin with radiance, firmness, and suppleness*5.

About SK-II SK-II has deeply connected with millions of people worldwide, aiming for "Freedom by Your Skin." SK-II's journey of beauty exploration began with the question of why the hands of elderly sake brewers were so beautiful. Through extensive research, it was discovered that the secret to beautiful skin lay within the fermentation process of sake brewing, leading to the creation of PITERATM*6, a unique ingredient derived from special yeast fermentation. Since then, SK-II products containing PITERATM*6 have been key to the beautiful skin of global ambassadors and have been supported by the trust of many customers regardless of age or skin type.

About PITERATM PITERATM*6 is a naturally derived ingredient unique to SK-II, created through a proprietary fermentation process using a special yeast strain (SK-II's proprietary Galactomyces ferment filtrate: skin-conditioning and moisturizing ingredient). It contains over 50 components, including vitamins, amino acids, minerals, and organic acids, and cannot be artificially created. PITERATM*6, which resembles the skin's Natural Moisturizing Factor (NMF), quickly penetrates the stratum corneum, maintaining the skin's health.
