Can Dehydrated Skin Get the Glass Skin Effect? Hyaluronic Acid for Hydration

September 23, 2026

Your skin looks shiny, but after cleansing it feels tight and seems dry?⚡️

In situations like this people often talk about dehydrated skin, even when the surface of the skin looks oily.

Glass Skin✨ is a K-beauty trend that describes skin that looks smooth, hydrated and naturally radiant. It isn't simply about having shiny skin: the Glass Skin effect is associated with a fresh, even look that is rich in hydration.

So how do you take care of hydration when your skin looks shiny but tends to feel tight?💧

In this article we'll look at why this feeling of dryness can appear and how to take care of it, focusing on hyaluronic acid and on some K-beauty products that contain it.

1. Why can skin look shiny but still be dehydrated?

The feeling of dehydrated skin can appear even when there is sebum on the surface and the skin looks shiny.

The skin's hydration level is linked to the water content of the stratum corneum and to water loss through the skin barrier, known as TEWL (Trans-Epidermal Water Loss). When the barrier function is compromised, water loss can increase and the skin can feel drier or tight.

So what are some of the main causes of this feeling?

✅ A weakened skin barrier

The skin barrier plays an important role in protecting the skin from external agents and in limiting water loss.

When its function is compromised, water loss can increase and contribute to the feeling of dryness or tightness.

✅ Over-cleansing and irritation

Cleansing your face too often, using very hot water or rubbing the skin hard can contribute to irritating it and compromising its barrier.

That's why, when your skin tends to get dry or tight, it can help to use a gentle cleanser, choose lukewarm water and avoid rubbing the skin hard.

✅A dry environment

An environment with little humidity can also affect the skin's water loss.

During drier seasons or in heated rooms, for example, the skin can feel drier and tighter.

2. Which ingredients can be used to hydrate dehydrated skin?

When caring for dehydrated skin, it's not only important to give the skin water, but also to think about how to keep it hydrated.

One of the most widely used ingredients for hydration is hyaluronic acid.

What is hyaluronic acid?

Hyaluronic acid (HA) is a substance that is also naturally present in the skin and can bind water, which is why it is widely used in cosmetics as a moisturising ingredient.💦

Numerous studies have looked at the topical use of hyaluronic acid in relation to skin hydration, and literature reviews report results that support its use in cosmetic products dedicated to hydration care.

So if your skin tends to be dry or tight, a product containing hyaluronic acid can be considered as one of the options for hydration care.

3. How to use hyaluronic acid in your skincare?

When using a product containing hyaluronic acid, you can also consider when you apply it and the hydration step of your routine.

After cleansing, you can apply a toner or serum containing hyaluronic acid while the skin is still slightly damp, followed by a moisturising product. The American Academy of Dermatology (AAD) also recommends applying moisturiser to skin that is still damp after cleansing or showering, to help hold water in the skin.

Hyaluronic acid, moreover, isn't used in just one type of product.

It's found in many K-beauty products, from toner pads to ampoules, from serums to creams, so you can choose different formulas depending on your routine and preferred texture.🩵

So let's look at some examples of K-beauty products that contain hyaluronic acid.

4. Which K-beauty products contain hyaluronic acid?

[MERZY V Hyaluronic Acid Hydrating Toner Pad]

MERZY V Hyaluronic Acid Hydrating Toner Pad contains 11 types of hyaluronic acid and vitamins B, C and E.

It can be used after cleansing, as part of the toning step. The embossed side can be used for gentle exfoliating care, thanks to PHA and sugar cane extract, while the soft side can be used for moisturising care.

The brand also suggests leaving the pad on the skin for 2–3 minutes, using it like a small mask. It can therefore be part of a routine aimed at skin that looks more hydrated and radiant.

[Genabelle Crystal Drop Hydra Booster Ampoule]

Genabelle Crystal Drop Hydra Booster Ampoule contains Triple Hyaluronic Complex 5,200 ppm and is formulated with a two-layer structure, made up of a water phase and an oil phase.

Before use, shake the product well to mix the two layers. It can be applied after toner, as part of your skincare routine.

The formula contains hyaluronic acid of different molecular weights, as well as D-panthenol and glyceryl glucoside. The oil phase also contains jojoba seed oil, which contributes to the care step dedicated to softness and keeping in hydration.

Combining the two layers therefore brings together hydration and care of the moisture film, making it especially suitable for a routine for skin that tends to get dry or have rough patches.

[BINSOON Squalane Intensive Moisture Cream]

BINSOON Squalane Intensive Moisture Cream contains 10,000 ppm squalane, 10 types of hyaluronic acid and 5,000 ppm panthenol.

Squalane and hyaluronic acid can be used in hydration care, while panthenol is an ingredient also used for skin barrier and hydration care.

It can be applied after toner and ampoule as the final step of your hydration routine. On days when your skin feels particularly dry, the brand also suggests applying a thicker layer for an intensive moisturising treatment.

As we've seen, hyaluronic acid isn't used in just one type of product – it's found in toner pads, ampoules, creams and other K-beauty formulas. Considering your skin's needs, the other ingredients in the formula and the product's texture can help you choose how to fit it into your routine.
