What Is Forsythia Koreana Branch/Leaf Extract?
Forsythia Koreana Branch/Leaf Extract comes from the twigs and foliage of Forsythia koreana, a flowering shrub in the olive family that blooms bright yellow in early spring across Korea and parts of East Asia. The plant is naturally rich in phenolic compounds such as forsythiaside, flavonoids and lignans, all known for their soothing and antioxidant properties.
For centuries Korean households have relied on forsythia infusions to calm the skin after sun exposure or irritation. As interest in traditional botanicals grew, cosmetic chemists began investigating the shrub’s branches and leaves rather than just the flowers, discovering a higher concentration of skin friendly compounds in these parts. Modern extraction usually starts with sustainably harvested branches and leaves that are washed, dried and milled. The plant material is then soaked in a gentle food grade solvent like glycerin or water, followed by filtration and concentration. The resulting liquid is standardized for consistent potency and preserved for use in formulations.
Today you can spot Forsythia Koreana Branch/Leaf Extract in soothing sheet masks, hydrating serums, anti aging creams, lightweight moisturizers, calming toners and after sun gels where its mild nature makes it suitable for daily use.

This botanical is prized for one main function in skincare formulations: skin conditioning. By delivering antioxidants and calming compounds it helps support the skin’s natural barrier, reduces the feeling of tightness and leaves the surface soft smooth and hydrated.
Who Can Use Forsythia Koreana Branch/Leaf Extract
Thanks to its gentle, water based profile Forsythia Koreana Branch/Leaf Extract is generally well tolerated by all skin types, including sensitive, dry, oily and combination. It is lightweight and non occlusive so it rarely aggravates acne prone skin or leaves a greasy film. There are no known concerns for darker skin tones or reactive rosacea prone complexions.
The extract is 100 % plant derived with no animal sourced additives, making it suitable for vegans and vegetarians. Most finished formulas that feature it also avoid animal by products, though it is always smart to scan the full ingredient list to be certain.
Current research and long standing traditional use suggest the ingredient is mild enough for women who are pregnant or breastfeeding. That said, safety data in these groups is limited, so this is not medical advice and anyone expecting or nursing should run all skincare products by a qualified healthcare professional just to be safe.
Forsythia Koreana Branch/Leaf Extract does not increase photosensitivity and can be used morning or night without elevating the risk of sunburn. It also plays well with common actives like niacinamide, panthenol and hyaluronic acid so you can layer it without worrying about unwanted interactions.

Comedogenic Rating
Rating: 0
Forsythia Koreana Branch/Leaf Extract is water soluble and contains virtually no fatty acids or heavy waxes that can block pores so it earns a 0 on the comedogenic scale. This makes it an easy fit for acne prone or oily skin that needs lightweight soothing ingredients. Its antioxidant phenolics can even help calm the look of active breakouts by reducing surface irritation. Because it is typically added at low percentages and sits in a watery base it does not alter the viscosity of formulas in a way that might trap sebum or debris.
