Medicube - Deep Peptide Radiance Mask (27ml)

Medicube Deep Peptide Radiance Mask is a single-use sheet mask built around a peptide complex, aimed at radiance and the look of fine lines. It is the anti-ageing option among Medicube's single sheet masks — where the Collagen Lifting Mask focuses on bounce and the Zero Pore Cooling Mask on pores, this one targets smoothness and glow.

What peptides do in a 20-minute mask

Peptides are short chains of amino acids — fragments of the proteins your skin already produces. Certain sequences act as signals, prompting skin cells to behave as though repair is needed, which over time supports firmness and smoothness.

Being realistic about the format: peptides work cumulatively, over months. A single sheet mask does not deliver a course of peptide treatment. What it does deliver is 20 minutes of concentrated, occluded hydration, which is genuinely effective at making skin look smoother and more radiant immediately — because dehydrated skin looks dull and exaggerates fine lines, and hydrated skin does neither.

So the sensible way to think about this mask: an excellent same-day radiance treatment, and a small contribution to longer-term peptide benefits. If firmness is your real goal, a daily peptide serum such as Hyaluronic Multi Peptide Serum does far more than a weekly mask.

The advantage of peptides over retinol here is tolerance — they are non-irritating, cause no purging, and are safe for sensitive skin. That makes this a mask you can use on nights when your skin is too reactive for anything else.

Do not let it dry out

Remove the sheet while it is still damp. A drying sheet mask reverses direction and draws moisture out of the skin. Fifteen to twenty minutes is the useful window — longer is not better.

How to use it

1. Cleanse and apply toner so the mask works on prepared skin.
2. Apply the sheet and smooth out air pockets.
3. Leave for 15–20 minutes, removing it while still damp.
4. Do not rinse — pat the remaining essence in.
5. Seal with moisturiser, and sunscreen in the morning.

Frequency: once or twice a week, or before an occasion. With no acids or retinoids, it is also a good recovery step after exfoliating or on a retinoid rest night.

Frequently asked questions

How long should I leave it on?

Fifteen to twenty minutes, removing it while the sheet is still damp. Leaving it to dry draws moisture back out of the skin.

Do I rinse afterwards?

No. Pat the remaining essence in and follow with moisturiser to seal it.

How often can I use it?

Once or twice a week. It contains no acids or retinoids, so there is no frequency limit for safety — more often simply offers diminishing returns.

Will one mask reduce my fine lines?

It will make them look softer immediately, because hydrated skin creases less visibly. Genuine improvement in fine lines takes months of consistent peptide use — a daily serum is the better route for that.

Are peptides better than retinol?

Not stronger, but far better tolerated. Retinol has the deeper evidence base for fine lines; peptides work more gently with no irritation or purging, which makes them practical for sensitive skin.

Can I use it after exfoliating?

Yes — it adds hydration without further actives, which makes it a sensible recovery step.

Should I use it before or after serum?

After cleansing and toner, before serum and moisturiser. The mask is the treatment step; your moisturiser seals it in.

Is it suitable for sensitive skin?

Yes. Peptides are non-irritating and there are no exfoliating actives. Patch test if you react easily.
