Melvieu Merry Serum 50ml

A water-free oil serum packed with active ingredients—no filler, just results

Instead of purified water, this highly concentrated serum is formulated entirely with nourishing plant oils—olive, jojoba seed, macadamia seed, and meadowfoam seed—plus targeted active ingredients. We've eliminated the purified water that typically makes up over 90% of conventional skincare and replaced it with hydration and nutrition your skin can actually use. Despite being an oil serum, it absorbs quickly and finishes with a soft, non-greasy feel that even oily skin types can wear comfortably.

A wrinkle-improving functional serum certified by the Ministry of Food and Drug Safety

Officially recognized by the Ministry of Food and Drug Safety as a wrinkle-improving functional cosmetic, this serum contains adenosine. Adenosine helps stimulate collagen and elastin production to support skin elasticity and target the appearance of fine lines. Skin irritation tested and suitable for sensitive skin.

Doubles as a makeup primer for seamless, long-lasting wear

Apply an appropriate amount as the final step of your skincare routine to smooth skin texture and boost the adherence of your base makeup. For oilier areas like the T-zone and center of the face, gently reapply a thin layer to help prevent makeup from lifting or sliding throughout the day. The texture hydrates from within while finishing with a soft, breathable feel—light enough to wear even in summer.

• Combination skin dealing with both dryness and excess oil
• Aging skin concerned with fine lines and loss of firmness
• Anyone whose makeup tends to break down or separate easily

At the end of your skincare routine, during the serum step

Merry Serum is designed to be used after toner and essence, right before your moisturizer. Formulated without purified water and packed only with oils and active ingredients, it delivers a concentrated dose of nourishment in the final stage of your skincare routine. If you're planning to apply makeup, you can skip moisturizer and go straight to base after this serum.

Suitable for both morning and evening use

In the morning, use it as a primer alternative before makeup. In the evening, let it replenish your skin after a long day. Despite being oil-based, it finishes with a soft, non-greasy feel, so your base makeup won't slip or separate when used in your AM routine.

Apply a thin, even layer

Dispense 2 to 3 drops with the dropper and gently spread across your entire face. For oilier areas like the T-zone and center of the face, add a second thin layer to help smooth out skin texture. Because it's an oil formula that absorbs without stickiness, the key is to build it up in thin layers rather than applying a thick coat all at once.

Recommended combinations by skin concern

• Combination skin with inner dryness: Layer over a hydrating toner to keep skin moisturized inside while maintaining a soft, balanced finish on the surface
• Aging skin concerned with elasticity and fine lines: Contains adenosine to help improve skin texture with consistent use
• Struggling with makeup longevity: Use in place of primer before base to smooth skin texture and boost adherence

Good to know before use

You may notice white particles at the bottom of the bottle. This is a natural crystallization of the adenosine ingredient and does not affect product quality. It absorbs naturally into the skin upon application. Store in a cool place away from direct sunlight, and if redness, itching, or other irritation occurs during use, discontinue and consult a dermatologist.
