★ LUXURY K-BEAUTY · NATURAL FERMENTATION

WATER.
FERMENTATION.
TIME.

SU:M37° (pronounced "Sum thirty-seven") is the Korean house of natural fermented skincare, created by LG Household & Health Care. Its name says it all: "SU" for water, "37°" for the ideal fermentation temperature of microorganisms. More than 80 plants, flowers, and fruits are fermented for hundreds of days to release bioavailable, concentrated, living active ingredients. A patient, sensory, premium K-beauty.

★ THE SU:M37° SIGNATURE

NATURAL FERMENTATION, THE HEART OF THE BRAND

One philosophy only: let time transform plants into living actives.

SU:M37° rejects synthetic preservatives and synthetic actives in favor of a long process: multi-strain natural fermentation of over 80 plant ingredients. The result is concentrated in Cinétiol®, the in-house fermented complex that nourishes all the ranges. Here are the 3 pillars of this signature.

✦ PILLAR 01

CINÉTIOL®

The brand’s signature fermented complex: a concentrate of plant extracts and microorganisms fermented together for 365 days to release amino acids, peptides, and antioxidants. The heart of the Secret Programming Essence.

✦ PILLAR 02

80+ FERMENTED PLANTS

Lotus, ginseng, peony flower, Korean fruits: over 80 plant ingredients are selected and then fermented together. Each season, the brand adjusts the composition according to the skin’s needs.

✦ PILLAR 03

ZERO SYNTHETIC PRESERVATIVES

Fermentation acts as a natural preservative. SU:M37° formulates without parabens, denatured alcohol, mineral oil, or artificial coloring: purity is claimed as its signature.

Time as an asset, fermentation as a method, purity as a requirement: SU:M37° is the most patient luxury K-beauty brand on the market, unique within the Amorepacific/LG galaxy.

★ YOUR QUESTIONS

SU:M37° FAQ

Everything you need to know about the purest fermented K-beauty.

Which SU:M37° product should I start with?

+

The Secret Programming Essence is the essential starting point: it’s the brand’s icon, a 365-day fermented essence that brightens, hydrates, and smooths in one step. For dehydrated skin, complement with the Water-full Skin Refreshing Toner.

What does fermentation do for my skin?

+

Fermentation transforms plant molecules into more bioavailable active ingredients that are smaller, more stable, and better absorbed by the skin. In practice: more radiance, a strengthened skin barrier, and prolonged effectiveness even at low concentrations.

Is it compatible with sensitive skin?

+

Yes, the brand was designed for that. SU:M37° excludes parabens, denatured alcohol, mineral oil, and artificial coloring. Fermented formulas are generally very well tolerated — still, do a patch test on your inner elbow before first use.

What is the difference between Secret Programming and Losec Summa?

+

Secret Programming is the multi-action fermented icon (radiance, hydration, early wrinkles). Losec Summa is the brand’s top tier, focused on deep anti-aging — firmness, established wrinkles, loss of density. Losec Summa is more precious, richer, and more targeted.

How long before seeing results?

+

With the Secret Programming Essence, radiance and comfort are visible in 2 to 3 weeks. For wrinkles and firmness (Losec Summa), expect 6 to 8 weeks of regular use — fermentation works deeply, not just on the surface.

Are the SU:M37° products on Ma Petite Corée authentic?

+

Yes, 100%. Ma Petite Corée has been based in Seoul since 2017 and sources directly. Every product is new, sealed, and shipped from Korea, with no customs fees charged to you in the EU.
