Inyoe Betaine Hydrogel Apple Oil Serum 30ml

Shake to Awaken: Betaine and Apple Seed Oil for Luminous Radiance

This is a dual-layer serum with a separated water and oil phase. Give it a shake before use, and the 80% water layer blends freshly with the 20% oil layer to deliver balanced hydration and nourishment. Formulated with a high concentration of 10% betaine (100,000ppm) and 3% apple seed oil (30,000ppm), it floods dry, rough skin texture with moisture and leaves behind a clear, light-catching glow. The watery oil texture absorbs lightly without the heaviness typical of oils.

Clinically Proven Hydration and Radiance

In a human application test conducted by the OATC Skin Clinical Test Center on 20 adult women aged 35 to 60, the following improvements were confirmed after just one use.

• Skin hydration (moisture level) improved by 197.99%
• Skin luminosity (radiance) improved by 33.95%
• Skin redness reduced by 30.57%
• Skin texture (roughness) reduced by 13.66%
• Moisture retention after 48 hours: 76.63%

The formula has also completed a low-irritation test on sensitive skin, confirming its gentle feel.

A Radiance Formula for Dry, Dull Skin

Betaine is a natural moisturizing factor that draws in hydration to quench dry skin, while apple seed oil, rich in linoleic and oleic acids, softens and smooths rough texture. The addition of 2% niacinamide, a tone-evening ingredient, helps clarify a dull complexion. Ideal for those whose skin feels tight right after cleansing, who find oils too greasy, or who want both hydration and glow in one step. This product has completed review as a brightening functional cosmetic.

Use after toner, before cream

Apply the oil serum right after toning, before your moisturizer. Its dual-phase formula combines water and oil, so it works as both an essence and a facial oil in one step. No need to layer a separate oil — it streamlines your routine beautifully.

Suitable for morning and evening use

In the morning, use it as a hydrating base before makeup. In the evening, let it replenish skin after a long day. Clinical testing confirmed 48-hour moisture retention, so on particularly dry days, apply a slightly more generous amount at night to wake up with skin that still feels hydrated.

Shake well, then dispense 2–3 drops

Before each use, shake the bottle thoroughly to blend the water and oil layers. Dispense 2–3 drops with the dropper, smooth evenly across your face, then gently press in with your palms. The watery texture absorbs quickly and leaves a non-greasy finish.

Recommended combinations by skin concern

• Dry, dull skin: Layer hydration with a rich toner → oil serum → moisture cream
• Tired, lackluster complexion: Contains niacinamide, so it doubles as a tone-evening serum
• Combination skin with imbalanced moisture-oil levels: After a lightweight toner, this alone may be enough to finish your routine

Storage and usage notes

Store in a cool place away from direct sunlight and use within 12 months of opening. Dermatologist-tested for sensitive skin, but if redness, itching, or irritation occurs during use, discontinue and consult a healthcare professional.
