sum37 Essences: Choosing Between the Lines
sum37 produces essences across three distinct lines - Rosh Summa, Secret, and Blossom Garden - each delivering the brand's slow-fermented botanical complex in a different concentration and concern focus. The 14+ essences in this collection cover repair, elixir treatment, moisturizing, and mist formats.
How essence fits into a sum37 routine
In sum37's product system, an essence is the second or third leave-on step after toning, applied before emulsions and creams. The essence step delivers the highest concentration of sum37's fermented active complex in a lightweight form that absorbs quickly before heavier layers go on top.
Using an essence before the emulsion is a core principle in Korean multi-step skincare. It allows the formula to penetrate while the skin surface is still prepared from the toner, and creates a hydrated base that subsequent products adhere to more evenly.
Rosh Summa essences: the premium repair tier
The Rosh Summa sub-line represents sum37's highest-grade botanical input base. The Rosh Summa Repair Essence 30 ml is a small-volume, concentrated repair essence focused on skin that is stressed, damaged, or showing barrier disruption. At 30 ml, it is the most compact of the essences and used sparingly as a targeted treatment add-on.
The Rosh Summa Elixir Essence Secreta 150 ml and Rosh Summa Elixir Treatment 150 ml are the full-size formats at the same premium tier. The Elixir Essence Secreta focuses on renewal and vitality; the Elixir Treatment has a richer treatment profile suited to mature skin with sustained renewal needs.
Rosh Summa Repair Essence 30 ml: the concentrated spot treatment
At 30 ml, the Repair Essence is the smallest essence in the range. Its concentration level is higher than the 150 ml formats, making it more appropriate for targeted application or as a supplement to a standard essence. Apply a small amount over areas of concern - dry patches, stressed zones, or areas with barrier disruption - after the main essence layer.
The Repair designation indicates it is formulated for recovery rather than general maintenance. It is not a daily first-essence replacement; it is a targeted add-on for skin under stress.
Secret Essence 150 ml: the standard daily first-treatment step
The Secret Essence 150 ml is the core essence for most users starting with sum37. It applies the fermented botanical complex at the first treatment step after toning, in a format that works across all skin types and ages. At 150 ml, one bottle lasts approximately two months at daily morning and evening use with two pumps per application.
It is the single most frequently recommended starting essence for new sum37 users. It is compatible with all other sum37 lines and can be paired with any emulsion or cream from the range.
Blossom Garden Moisturizing Essence 40 ml: hydration-focused
The Blossom Garden Moisturizing Essence 40 ml is part of sum37's lighter, fragrant-floral product line. It prioritizes hydration and moisture delivery rather than intensive treatment or renewal. The 40 ml size is compact and suitable as a travel essence or secondary essence step layered over the Secret Essence for extra moisture.
It suits skin that is already in good condition and needs daily moisture maintenance more than active treatment. The Blossom Garden line has a more accessible entry price and a softer active profile than the Rosh Summa or Secret lines.
Breath Secret Essence Mist 180 ml: spray-on delivery
The Breath Secret Essence Mist 180 ml delivers the Secret essence formula in a fine-mist spray format. Mist application distributes the essence evenly without hand contact, which reduces friction on sensitive or reactive skin. It can be used before the main essence layers to create a wet base, or as a mid-day refresh over makeup.
At 180 ml, the bottle is larger than most mist formats, providing a generous supply. The Breath sub-line integration means it uses the 37 Degree fermentation activation principle alongside the Secret complex.
Waterpool Ampoule Essence Planning Set
The Waterpool Ampoule Essence Planning Set bundles ampoule-format essences from the Water Pool line. Ampoules are higher-concentration serums in small single-use or multi-use vials, delivering an intensive dose of actives that is stronger than a standard essence per application.
A planning set bundles these at a lower per-unit cost than buying ampoules individually. The Water Pool ampoule base uses the aqua-gel hydration focus of the Water Pool line, making these suited to dehydrated skin that needs a quick intensive hydration boost.

When should I use the sum37 Rosh Summa Repair Essence 30 ml instead of the Secret Essence 150 ml?
Use the Rosh Summa Repair Essence 30 ml when skin is showing barrier disruption, dryness, redness, or stress from environmental factors or product over-use. Apply it over areas of concern as a targeted add-on after your main essence. The Secret Essence 150 ml is the standard daily first-treatment step; the Repair Essence is for recovery situations.
What is the difference between the sum37 Rosh Summa Elixir Essence Secreta and the Rosh Summa Elixir Treatment?
Both are 150 ml Rosh Summa tier products at the premium grade. The Elixir Essence Secreta focuses on renewal and vitality and applies as a first-treatment essence. The Elixir Treatment has a richer treatment profile oriented toward sustained daily renewal for mature skin. The Treatment is the more intensive of the two.
Who is the sum37 Blossom Garden Moisturizing Essence 40 ml for?
The Blossom Garden Moisturizing Essence suits skin in good condition that needs daily moisture maintenance without intensive treatment actives. It also works as a secondary essence step layered after the Secret Essence for users who want extra hydration. The 40 ml compact size suits travel or occasional use.
Which sum37 essence should I start with if I'm new to the brand?
The Secret Essence 150 ml is the recommended starting point. It is the most versatile, applies across all skin types, and represents sum37's core fermented botanical complex at the standard essence concentration. It provides two months of daily use at two pumps per application.
Is the sum37 Breath Secret Essence Mist 180 ml as effective as applying the Secret Essence from a bottle?
The mist delivers the same Secret essence formula in a spray format. Mist application is slightly less concentrated per square centimeter than hand-pressed drops, but it covers the face more evenly with less friction. For sensitive or reactive skin, the mist is preferable. For maximum concentration per application, the bottled Secret Essence applied with hands delivers a higher dose.
What is the difference between the sum37 Waterpool Ampoule Essence and a regular essence?
Ampoules are more concentrated than standard essences. They deliver a higher active load per application in a smaller volume. The Waterpool Ampoule uses the Water Pool aqua-gel hydration base in this intensive format. Use ampoules as a booster step between toner and the standard essence, or as a full replacement during intensive hydration periods.
