BINSOON Deep Moisture Serum Birch Sap + Hyaluronic Acid 40ml

A multi-layer moisture reservoir powered by 10 types of hyaluronic acid

binsoon Deep Moisture Birch Sap Serum is an ampoule that delivers 10 types of hyaluronic acid, ranging from high to low molecular weight, to build moisture layers deep within the skin. Its lightweight texture sits between water and gel, absorbing quickly on contact and finishing fresh without any sticky residue. A clinical study showed a 117% improvement in skin hydration after just one use, making it a go-to for anyone struggling with dehydration beneath the surface.

Barrier care perfected by birch sap and panthenol

This formula is designed not just to deliver moisture, but to help it stay put. Each key ingredient plays a distinct role in fortifying the skin's moisture barrier.

Birch sap supplies minerals and hydration while soothing dry, stressed skin. Aquaxyl, a patented birch-derived ingredient, prevents moisture loss and enhances retention. Panthenol at 5,000 ppm supports compromised barriers and maintains a comfortable, hydrated environment. Betaine, allantoin, and adenosine work together to support moisture circulation, calm irritation, and refine overall skin condition.

A gentle formula safe for daily use, even on sensitive skin

It scored 0.00 on a dermatological patch test for irritation and is formulated without fragrance to minimize potential triggers. Every ingredient is rated EWG Green, making it suitable for even the most reactive skin types. On particularly dry days, layering the serum two to three times helps build up moisture intensity. Ideal for those with dehydrated skin that feels tight no matter what, anyone who wants lasting hydration without the stickiness, and those looking for a smooth, makeup-ready base.

After toner, before essence and cream

Use binsoon Deep Moisture Serum right after cleansing and toning, when your skin is freshly prepped. Its 10-type hyaluronic acid complex is designed to draw in moisture, so applying it over damp, toner-prepped skin helps boost absorption. Follow with a cream or oil to lock everything in and keep hydration from evaporating throughout the day.

Morning and evening use

With a 0.00 skin irritation index, this formula is gentle enough for daily use, morning and night. In the morning, layer it under makeup as a hydrating base. In the evening, use it to replenish moisture after a long day.

Dispense a small amount and smooth on lightly

Dispense 2–3 drops onto your palm using the dropper, then gently press and smooth over your entire face. The texture sits between water and gel, so it absorbs quickly with a light patting motion and leaves no sticky residue. On particularly dry days, you can layer it 2–3 times using the same method to build up deeper hydration.

Routine pairings by skin concern

• Combination skin with inner dryness: After toner, let this serum fully absorb, then seal with a lightweight hydrating cream.
• Oily skin that wants moisture without oil: Use the serum on its own, or pair it with a hydrating gel for a fresh, non-greasy finish.
• Very dry skin: Layer the serum 2–3 times, then lock it all in with a rich nourishing cream.

Storage and usage notes

Store in a cool place away from direct sunlight, and use within one year of opening. If you have extremely sensitive skin, patch-test behind your ear or on your inner arm before applying to your face. If you experience redness, itching, or any irritation during use, discontinue immediately and consult a dermatologist.
