Core Product Details

A Moisture-Drenched Ritual for Supple, Luminous Skin

COS DE BAHA HP Hyaluronic Acid B5 Serum transforms daily hydration into a sensorial South Korean skincare ritual. Created around moisture-loving ingredients and a verified 4% concentration of panthenol, this lightweight serum is designed to replenish dehydrated-feeling skin and help maintain precious moisture. Sodium hyaluronate, glycerin and betaine complement its hydration-focused character, leaving the complexion feeling softer, smoother and comfortably replenished. For anyone seeking a Korean hydrating serum for dry or dehydrated skin, HP Serum offers an elegant layer of moisture without turning the ritual unnecessarily complicated.

4% Panthenol for Moisture & Skin Barrier Support

Panthenol, also known as provitamin B5, takes a starring role at 4%. Valued for its humectant and skin-conditioning qualities, panthenol helps support hydration and the skin's natural moisture barrier, making the formula particularly alluring when dryness leaves the complexion feeling less comfortable or supple. It transforms hydration from a fleeting sensation into a more considered ritual of moisture preservation, helping skin feel beautifully conditioned and cared for.

Hyaluronic Acid for a Plump, Dew-Kissed Appearance

Sodium hyaluronate brings the moisture-binding appeal associated with hyaluronic acid skincare, helping attract and retain water at the skin's surface. Paired with glycerin and betaine, it supports a complexion that feels replenished and appears smoother and more supple. Rather than promising to erase wrinkles, this moisture-rich approach helps soften the appearance of dehydration-related fine lines, creating the fresh, cushiony look that makes Korean glass-skin rituals so captivating.

2% Niacinamide Adds a Touch of Brightening Refinement

Hydration is joined by 2% niacinamide, giving this Korean hyaluronic acid serum an additional complexion-refining dimension. Niacinamide helps support a brighter, more even-looking tone while complementing the formula's moisture-focused character. It is a thoughtful pairing for skin that appears dull when dehydrated, bringing together luminosity and comfort rather than treating them as separate desires.

Aloe, Allantoin & Botanical Care Complete the Experience

Aloe vera leaf extract forms the base of the verified ingredient list, accompanied by soothing allantoin and a botanical ensemble of Damask rose, lavender, green tea, lemon balm and mugwort extracts. Together, they lend the composition a distinctly botanical dimension while supporting the serum's conditioning character. The formula feels emblematic of modern K-Beauty: targeted ingredients surrounded by hydration and plant-derived care for a ritual that feels both purposeful and indulgent.

Effortless Hydration for a Layered Korean Skincare Routine

After cleansing and toning, smooth a moderate amount across the complexion and gently pat or massage until absorbed before following with moisturizer. Its hydration-first approach makes HP Serum an effortless companion to a layered Korean skincare routine, where toner, serum and cream build moisture in delicate stages rather than relying on a single heavy layer. During the day, complete the ritual with sunscreen for a polished finish that protects the care invested beneath it.

Where Every Drop Becomes an Invitation to Softness

Made in South Korea, COS DE BAHA HP Hyaluronic Acid B5 Serum celebrates one of K-Beauty's most irresistible pleasures: skin saturated with thoughtful hydration. Panthenol, hyaluronic acid, niacinamide and botanical extracts turn an everyday serum step into a quiet act of devotion to your complexion. The reward is not excess, but beautifully conditioned skin that feels supple and looks fresh, smooth and luminous—the unmistakable allure of a moisture-rich ritual performed simply because your skin deserves the attention.
