Beauty of Joseon Light On Serum: Centella + Vita C 30mL

A vitamin C serum is a leave-on step used for cosmetic care of radiance and uneven-looking skin tone. Different formulas use different forms of vitamin C, so the ingredient name matters; a derivative should not be described as pure ascorbic acid. Apply serum before moisturizer and follow daytime skincare with sunscreen.

Light On Serum uses 3-O-ethyl ascorbic acid alongside centella extract and panthenol. Its lightweight formula balances a brightening-care focus with hydration and conditioning ingredients. Gently pat an appropriate amount over the face after cleansing and toning, allowing it to absorb before moisturizer rather than rinsing it off.

A vitamin C derivative paired with centella and panthenol

The formula combines appearance-focused and moisturizing ingredients in one light serum, with the specific vitamin C derivative clearly distinguished from other forms used in skincare.

• 3-O-ethyl ascorbic acid: The verified formula lists this vitamin C derivative at 10%. It is not the same ingredient as pure ascorbic acid and should be understood as part of the complete formulation.
• Centella asiatica extract: The ingredient list specifies centella extract at 6,800 ppm in this version, contributing to its conditioning component.
• Panthenol: Panthenol is listed at 1% and complements the formula's moisturizing and comfort-focused ingredients alongside the vitamin C derivative.
• Alpha-bisabolol: This ingredient provides an additional conditioning component in the serum rather than a separate treatment applied afterward.
• Humectant blend: Glycerin, propanediol and betaine are included among the ingredients that help maintain a hydrated skin feel during the serum step.
• Beta-glucan: Beta-glucan accompanies the other moisturizing components, contributing to a formula that addresses comfort as well as visible radiance.
• 30mL lightweight serum: The product absorbs without a heavy or sticky feel and fits after cleansing and toning, followed by moisturizer and sunscreen during the day.

Radiance-focused care with comfortable hydration

Light On Serum addresses the appearance of dullness and uneven tone while retaining a light, moisturizing feel. Its benefits are cosmetic, not a guarantee that all pigmentation will disappear.

• Brighter-looking skin: The vitamin C derivative supports a clearer, more luminous appearance, giving the serum a focused role in a routine concerned with dullness.
• Uneven-tone care: The formula helps improve the appearance of visible dark spots and uneven-looking tone, with results depending on individual skin and consistent use.
• Hydrating comfort: Panthenol and humectants help maintain moisture alongside the brightening-care ingredients, so the serum experience is not focused only on appearance.
• Conditioned skin feel: Centella and alpha-bisabolol complement the moisturizing base, supporting comfortable-feeling skin without turning cosmetic soothing into a medical treatment claim.
• Lightweight routine fit: The texture absorbs without heaviness or stickiness. Apply after toner and before moisturizer, then use sunscreen during daytime care so the serum remains one defined step rather than a replacement for sun protection.
