WHY WE PICKED IT

Hydrogel masks vary hugely in quality, and the difference usually comes down to the technology. This one made the cut because of the science behind it.

Its firm yet flexible hydro-matrix hugs the face and gradually melts into the skin, delivering ultra-fine 300-dalton collagen and hyaluronic acid. After around 30 minutes it turns transparent, a sign the formula has been absorbed, leaving skin smoother and more supple with no stickiness.
Key Benefits

• Hydration: Hyaluronic acid replenishes moisture without stickiness.
• Smoother texture: Retinal helps refine the look of texture and pores.
• Bounce: 300-dalton collagen helps skin look firmer and plumper.
• Suppleness: Skin feels softer and more elastic after 30 minutes.
Best for

Dry skin with visible texture, enlarged-looking pores or a loss of suppleness.
When we’d use it

When skin needs a smoothing boost. Make it part of a routine that feels good, not another step you have to do.
What caught our attention

The 300-dalton collagen. Collagen molecules this small are better suited to working beyond the surface, and pairing them with retinal, a form of vitamin A, helps with texture and the look of pores.
What we love about the brand

CKD is one of Korea’s longest-standing healthcare companies, known for everything from probiotics to nutrition. That pharmaceutical precision shows in how carefully its skincare is formulated.
The Sonagi Verdict

A considered choice for dry skin with visible texture. The appeal is simple: hydrate and improve the look of skin texture and suppleness, without the exaggerated promises.

The product page does not recommend overnight application.

Why does the CKD Retino Collagen Hydrogel Mask turn transparent?

The CKD Retino Collagen Hydrogel Mask gradually becomes transparent during application as its hydrogel matrix releases the formula onto the skin. SONAGI explains that this process usually takes around 30 minutes, although it can take longer than 40 minutes depending on skin condition. The change in appearance provides a practical indication of when to remove the mask according to the product instructions.

Is the CKD Retino Collagen Hydrogel Mask good for dry skin?

The CKD Retino Collagen Hydrogel Mask is designed to provide hydration and improve skin suppleness. Its featured ingredients include Hyaluronic Acid and 300-dalton Hydrolysed Collagen, which contribute to the mask's moisturising and skin-conditioning focus. SONAGI describes the formula as hydrating and non-sticky. However, the product page does not specifically confirm suitability for every dry or sensitive skin type.

Can the CKD Retino Collagen Hydrogel Mask help minimise pores?

The CKD Retino Collagen Hydrogel Mask is designed to minimise the visible appearance of enlarged pores. SONAGI highlights pore appearance as one of the mask's main benefits, alongside hydration and improved-looking elasticity. The formula contains Hydrolysed Collagen, Hyaluronic Acid and Retinal. These benefits relate to the cosmetic appearance of pores rather than permanently reducing their natural size.

What ingredients are in the CKD Retino Collagen Hydrogel Mask?

The CKD Retino Collagen Hydrogel Mask features 300-dalton Hydrolysed Collagen, Retinal, Hyaluronic Acid and Elastin Proteins, according to SONAGI's product description. These ingredients are highlighted for supporting hydration, skin suppleness and a firmer-looking complexion.

This ingredient forms part of the mask's hydrating and skin-conditioning formula, designed to leave the complexion looking smoother, firmer and more supple. The stated molecular weight should not be interpreted as proof that topical collagen permanently replaces the skin's natural collagen.

Does the CKD Retino Collagen Hydrogel Mask contain retinal or retinol?

SONAGI's description of the CKD Retino Collagen Hydrogel Mask identifies Retinal as a featured ingredient. Retinal and Retinol are related vitamin A derivatives, but they are not identical ingredients. The product page does not provide a complete INCI list or state the Retinal concentration.
