Pyunkang Yul Black Tea Boosting Serum 45ml — Kombucha + Peptides for Firmer, Plumper Skin

Pyunkang Yul PKY Black Tea Boosting Serum is a concentrated 45ml serum that uses fermented black tea (kombucha), ginseng berry extract, peptides and adenosine to nourish skin, help reduce the appearance of fine lines, and restore a firmer, plumper texture without irritation.

Made in Korea by Pyunkang Yul, this dense yet fast-absorbing serum combines condensed fermented black tea with targeted revitalizing actives to supply deep moisture and visible elasticity. The formula emphasizes gentle, skin-friendly ingredients designed for sensitive skin types, layering smoothly under creams or makeup. It aims to strengthen skin resilience and support a more buoyant complexion through a blend of natural extracts and clinically familiar ingredients like peptides and adenosine.

How does this serum improve skin firmness and texture?

The serum concentrates kombucha, a fermented black tea containing polyphenols and catechins, to feed skin with antioxidant-rich nourishment while supporting elasticity. Peptides and adenosine work alongside botanical nutrients to promote smoother-looking skin and reduce the appearance of dehydrated fine lines.

• Condensed fermented black tea supplies antioxidant and conditioning molecules.
• Peptides help support skin structure for a firmer surface look.
• Adenosine aids visible smoothing of fine lines caused by dehydration.
• Light, non-sticky texture allows efficient ingredient delivery.

Will this serum suit sensitive or easily irritated skin?

Pyunkang Yul formulates this serum for low irritation potential, using gentle botanical extracts and avoiding heavy fragrances. Its texture is highly enriched yet designed to absorb refreshingly rather than sit on the skin, minimizing pore-clogging or residue that can trigger sensitivity.

• Thoughtful ingredient selection for reduced irritation risk.
• Absorbs into skin without sticky finish, suitable for layering.
• Recommended for reactive skin when patch-tested first.

How should I use the Black Tea Boosting Serum in my routine?

Apply the serum after cleansing and toning, while skin is slightly damp, to maximize absorption. A few drops massaged across face and neck are enough; follow with moisturizer and sunscreen in the daytime or a richer cream at night for sealing in nutrients.

• Use morning and evening for consistent support.
• Apply 2–3 drops to cleansed, toned skin and pat gently.
• Layer under moisturizer and sunscreen in daytime routines.
• Works well with other Pyunkang Yul products or minimal routines.

What active botanicals deliver the serum’s benefits?

Key plant-derived ingredients include fermented black tea (kombucha) for antioxidant energy, ginseng berry extract for rich nourishment, and seaberry for vitality and deep skin conditioning. These botanicals are paired with peptides and adenosine to support visible texture improvement and a more resilient feel.

• Fermented black tea (kombucha) — antioxidant-rich, supports firmness.
• Ginseng berry extract — concentrated nourishment for elasticity.
• Seaberry extract — boosts skin vitality and conditioning.
• Peptides and adenosine — clinically used for smoothing and resilience.
