I used Korean skincare for years. These two give me the same feeling as the ten products I used before.
Cecilia✓ Verified buyer · Boost★★★★★
Light, sinks in fast, never sticky. My skin is less dry and after a few weeks some fine lines are smaller.
Jesper✓ Verified buyer · Boost★★★★★
Sinks in without feeling sticky. Noticeably softer and more hydrated by morning. My dry patches have calmed down.
Susanna✓ Verified buyer · Boost★★★★★
Exactly three weeks in and there is already a difference. Above all you can feel it, and that matters most.

PDRN
27.8%faster skin-barrier repair activity
PDRN (polydeoxyribonucleotide) is made of purified DNA fragments. It was first developed to help wounds heal, and dermatologists in Seoul have used it in clinic treatments since the early 2000s, where it goes in with a needle.
In skincare it supports the skin's own repair activity and helps calm redness. Muby uses Hayan PDRN complex, a vegan PDRN, in both the serum and the cream, so it is part of every morning and every night.
Nine signal peptides, including copper peptide GHK-Cu, that tell skin to make collagen and elastin.

9-Peptide complex
53.3%improvement in skin texture after 8 weeks
Peptides are short chains of amino acids that act as messengers to your skin. They tell it to make more collagen and elastin, the two proteins that keep skin firm and smooth. One peptide is one message; nine peptides cover more pathways at once.
One of the nine is copper peptide GHK-Cu, first isolated in 1973 and one of the most studied peptides in skincare. Peptides are gentle enough for daily use, morning and night.
One of three ingredients Korea approves for an anti-wrinkle claim, at the full dose.
0.04%the full MFDS functional dose
Wrinkle care · Boost · Moist
Adenosine
0.04%the full MFDS functional dose
In Korea a product may only be called anti-wrinkle if it contains an ingredient approved by the MFDS, Korea's food and drug authority, at a set dose. Adenosine is one of three such ingredients, and the dose is 0.04%.
Muby has the full dose in both products. Adenosine gives skin cells energy for repair and supports collagen, and it works well alongside every other active in the routine. It is everywhere in Korean skincare and still rare in Europe.
One of three MFDS-approved anti-wrinkle ingredients
An extremolyte from salt-lake microbes. Builds a water shell around each cell and cuts water loss.

Ectoin
Shieldcold · wind · dry air · pollution · UV
Ectoin is an extremolyte: a molecule that microbes in salt lakes and deserts make to survive drought, salt and strong sun. On skin it does a similar job. It binds water into a shell around each cell, helps hold the skin's lipids in place and reduces water loss.
That makes it a shield against what dries out and irritates skin in a Nordic climate: cold, wind, dry indoor air and pollution, and it helps calm skin stressed by the sun. It is not a sunscreen, so keep using SPF. Ectoin is very well tolerated, also by dry and sensitive skin.
Rice ferment in the serum; pear, pomegranate, soybean and barley ferments in the cream.

Fermentation breaks plant ingredients into smaller molecules and creates new ones that skin can use. That is why ferments behave differently from plain extracts, and why they are at the heart of Korean skincare.
Boost has rice ferment, the tradition behind Korea's best-known essences. Moist has pear, pomegranate, soybean and barley ferments.

Niacinamide
+67%ceramide synthesis, documented
Niacinamide (vitamin B3) is one of the most studied actives in skincare. It helps skin make more of its own ceramides, fatty acids and cholesterol, the lipids that hold the barrier together. In published research it raised ceramide synthesis by up to 67%.
It also helps even out skin tone and calm redness, and it pairs with everything. Muby combines it with ceramide NP and panthenol, so skin gets help making its own ceramides and gets ceramides on top.
It is the question that stops people at one product. Short answer: the serum carries the repair actives; the cream keeps them there.
PDRN and peptides go on first
Boost carries the Hayan PDRN complex and the 9-peptide complex. It goes on first, under the cream, so the actives sit right on the skin before Moist seals them in.
No sting, no acids, no retinoids
Nothing in Boost exfoliates or peels. Rice ferment and panthenol calm on contact, which is why reactive skin tolerates it.
Two to three drops, not a pipette
On damp skin, morning and night. Oily or acne-prone skin uses one to two drops.

For barrier repair, hydration, firmness and tone: yes. Keep a gentle cleanser and an SPF; neither needs to be complicated.

Do I still need SPF?
We don't make one yet. Use it anyway. SPF is cool.
