Ultra-Low Molecular Hyaluronic Acid Serum – hyaluronic acid moisturizing serum

💧 Ultra-Low Molecular Hyaluronic Acid Serum – intensive yet lightweight hydration

Dehydrated skin is not necessarily dry: it may become shiny during the day while feeling tight after washing. The Isntree Ultra-Low Molecular Hyaluronic Acid Serum targets this moisture-deficient condition with a light, watery serum texture and versatile hydrating ingredients.

The formula’s speciality is the combination of 14 types of hyaluronic acid and sea water from around Ulleung Island. The aim is plumper, softer, more elastic-feeling skin – without adding a heavy, greasy layer to your routine.

✨ What does it do?

• 💧 Multi-level hydration – the different forms of hyaluronic acid help retain moisture, making the skin appear fuller and smoother.
• 🌊 Sea water formula – sea water linked to Ulleung Island gives the serum one of its distinctive features.
• 🫧 Light, layerable texture – spreads quickly and fits easily between toner and moisturiser.
• 🌿 Skin comfort – panthenol, allantoin, madecassoside and beta-glucan not only hydrate but also enhance skin comfort.
• ✨ Fresher complexion – fine lines emphasised by dehydration may appear less noticeable.
• 💗 Everyday usability – fits well into morning and evening routines and suits various skin types.

🧬 Key ingredients and their benefits

💧 14 types of hyaluronic acid

Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate and other hyaluronic acid derivatives are moisture-binding agents with different properties. Their combination supports longer-lasting hydration on the skin surface and a plumper overall effect.

🌊 Sea water from the Ulleung Island region

A distinctive element of the formula’s water base. Together with other hydrating ingredients, it makes the serum experience light and refreshing.

🌿 Panthenol, allantoin and madecassoside

These ingredients are welcome in routines aiming to soothe tight, uncomfortable skin and promote a calmer appearance.

💦 Betaine, Glyceryl Glucoside and beta-glucan

Additional moisture-binding and skin-conditioning ingredients that complement hyaluronic acid hydration, especially during heating season or in dry air.

🌸 What makes this hyaluronic acid serum special?

• It does not rely on a single form of hyaluronic acid: the hydrating system composed of various derivatives targets softness and a more elastic skin feel.
• Light texture: especially suitable when you want plenty of hydration but dislike thick, heavy serums.
• Good companion to other active ingredients: can complement retinol, acid or vitamin C routines as a hydrating addition if your skin tolerates the combination.

🎯 Who do we recommend it for?

Especially suitable for:

• dehydrated, tight facial skin,
• combination or oily yet dehydrated skin,
• as a hydrating layer for dry skin,
• dull, tired-looking skin,
• fine lines emphasised by lack of hydration,
• those who prefer to start hydration with a light serum instead of a rich cream.

💗 Why do we love it?

We love that it approaches hyaluronic acid hydration in a truly versatile way. The serum does not try to be a strong exfoliating or anti-wrinkle treatment at once: it focuses on a plumper, more comfortable skin surface and complements a mindful routine very well.

❓ Frequently asked questions

Better for dry or oily skin?

It can be used for both. It is especially useful if the skin is dehydrated: this can occur in both dry and oily skin types.

How many types of hyaluronic acid does it contain?

The manufacturer highlights 14 types of hyaluronic acid forms, which appear under different INCI names in the ingredient list.

Can I use it alongside niacinamide or retinol?

Yes, it can be well integrated as a hydrating supplement in such routines. Always adjust the other active ingredients according to your skin’s tolerance.

Do I need a face cream afterwards?

We recommend finishing your routine with a moisturising cream after the serum: this helps to preserve the moisture bound in the skin.

Is it good under makeup too?

Due to its light texture, it can work well under makeup for many; allow it to absorb before applying the next layer.
