Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A fermented water-based extract combining Korean angelica root and stem, licorice root, rehmannia root, safflower flower, peach seed, and poria cocos mushroom. The fermentation step is intended to enhance the bioavailability of the plants' natural antioxidants and soothing compounds.

How it works

The blend provides antioxidant compounds (like flavonoids from safflower and licorice) that help neutralize free radicals from UV and pollution. Licorice root contains glabridin, known for soothing and brightening properties. Fermentation may create smaller active molecules that penetrate the skin more easily, while the water base delivers hydration without heaviness.

Pros

Multi-plant antioxidant blend

Combines several traditional herbal extracts in one ingredient, offering a range of antioxidant and soothing compounds without needing multiple separate ingredients.

Fermentation may boost efficacy

The fermentation process can break down larger plant molecules into smaller ones, potentially making the beneficial compounds easier for skin to absorb and use.

Cons and cautions

Limited specific research

While the individual botanicals have some supporting studies, there is very little published research on this exact fermented combination, so its benefits are inferred rather than proven.

Potential for variability

The quality and effects of this ingredient can vary widely between brands depending on the fermentation conditions, plant sourcing, and final concentration in the product.

Best for

  • People with normal, combination, or oily skin looking for lightweight antioxidant support
  • Those interested in K-beauty style fermented ingredients for soothing and glow

Use caution if

  • Individuals with known allergies to any of the constituent plants (e.g., Asteraceae family for safflower)

Usage tips

Look for this ingredient in the first half of the ingredient list to ensure a meaningful concentration
Pair with a simple moisturizer to lock in the antioxidant benefits without overwhelming your routine

Safety summary

This fermented botanical blend is considered safe for topical use with a low irritation and comedogenic risk. As with any plant-based ingredient, individuals with specific plant allergies should patch test first. The fermentation process is generally well-tolerated.

Research notes

Individual components like licorice root and safflower have moderate evidence for antioxidant and soothing effects in skincare. However, there are no peer-reviewed studies on this exact fermented combination. The evidence level is emerging.
