Core Product Details

5% Stabilized Vitamin C for Fresh, Luminous Clarity

COS DE BAHA VM Vitamin C MSM Serum transforms antioxidant skincare into a refined South Korean ritual for luminosity, clarity and beautifully conditioned skin. Rather than using pure L-ascorbic acid, the formula features 5% Sodium Ascorbyl Phosphate, a stabilized vitamin C derivative selected to help brighten uneven-looking tone while providing antioxidant benefits with a gentler approach. Its clear, watery texture absorbs quickly, making this Korean vitamin C serum an elegant daily treatment for dullness, dark spots and a complexion longing to recover its natural radiance.

Vitamin C & MSM Create a Distinctive Brightening Pair

Alongside 5% Sodium Ascorbyl Phosphate sits 1% MSM, or Dimethyl Sulfone, creating the combination that defines COS DE BAHA VM Serum. The manufacturer positions MSM for soothing and skin-conditioning care while vitamin C focuses on brightness, tone and antioxidant support. Together, they create a versatile treatment for complexions affected by visible blemish marks, unevenness and lacklustre tone, bringing a fresh sense of refinement to daily K-Beauty skincare.

Ferulic Acid & Vitamin E Elevate the Antioxidant Ritual

Ferulic acid and tocopheryl acetate, a vitamin E derivative, add another sophisticated dimension to the formula. Both contribute antioxidant benefits, complementing the stabilized vitamin C at the centre of the serum. COS DE BAHA specifically highlights ferulic acid for enhancing the effectiveness of vitamin C, while vitamin E contributes moisturizing and antioxidant care. The result is a thoughtfully composed Korean antioxidant serum that reaches beyond brightness alone to support a complexion that looks fresh, polished and vital.

Hyaluronic Acid Wraps Radiance in Weightless Hydration

Sodium hyaluronate brings moisture-binding hydration to the experience, accompanied by aloe vera, betaine and glycereth-26. Allantoin and dipotassium glycyrrhizinate further support the serum's soothing and conditioning character. This moisture-conscious foundation allows brightening care to remain sensorial and comfortable, helping skin feel supple and replenished while encouraging the plump, luminous appearance associated with a beautifully layered Korean glass-skin routine.

Botanical Extracts Complete the South Korean Formula

Green tea, elderflower, bitter melon and edelweiss extracts complete the verified ingredient composition, surrounding the central vitamin C, MSM and antioxidant complex with botanical care. The formula feels distinctly modern in its approach: a stabilized vitamin C derivative supported by hydration and complementary antioxidants rather than relying on unnecessary complexity. It is skincare created for the beauty lover who wants performance to feel as elegant as the ritual itself.

A Vitamin C Serum Designed for Morning or Evening

After cleansing and toning, apply an appropriate amount before moisturizer and gently pat until absorbed. COS DE BAHA's current directions allow VM Serum to be used daily, morning or evening. During daytime use, complete the ritual with sunscreen. Although the Sodium Ascorbyl Phosphate used in VM Serum is more stable than pure vitamin C, COS DE BAHA confirms that natural oxidation can still occur, making thoughtful storage away from excessive light and heat an important part of caring for the formula.

A Golden Drop of Korean Radiance for the Modern Complexion

Made in South Korea, COS DE BAHA VM Vitamin C MSM Serum captures the magnetic pleasure of skin that looks fresh, illuminated and beautifully cared for. Stabilized vitamin C meets MSM, ferulic acid, vitamin E and hyaluronic acid in a formula that turns antioxidant care into an intimate daily ritual. Each weightless application invites dull, uneven-looking skin toward greater luminosity while moisture restores the softness and suppleness that make radiance feel truly irresistible.
