Ingredient review
Tiliroside
INCI: Tiliroside
Tiliroside is a gentle plant antioxidant that may help calm redness and defend skin from daily pollution, though human studies are still limited.
In plain English
Tiliroside is a natural compound found in plants like linden flowers and strawberries. In skincare, it acts as an antioxidant, meaning it helps neutralize free radicals—unstable molecules from UV rays and pollution that can damage skin cells. It also has soothing properties, which may help reduce visible redness or irritation. Think of it as a gentle shield that supports your skin's natural defenses without harsh side effects.

What it is
Tiliroside is a flavonoid glycoside, a type of plant pigment with antioxidant activity. It is extracted from sources such as linden (Tilia) flowers, rose hips, and certain berries.
How it works
In a cosmetic product, tiliroside works by donating electrons to neutralize free radicals, preventing them from oxidizing skin lipids and proteins. It also appears to inhibit certain inflammatory pathways, which can help calm irritated skin and reduce redness.
Pros
Gentle on skin
Tiliroside has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Dual action
It combines antioxidant protection with soothing benefits, addressing both environmental stress and visible redness in one ingredient.
Cons and cautions
Limited research
Most evidence comes from lab or animal studies; human trials are scarce, so its real-world efficacy is less certain.
Lower potency
Compared to well-studied antioxidants like vitamin C or ferulic acid, tiliroside's antioxidant power is milder and may not be as effective for high-stress skin.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with sensitive or reactive skin who want soothing support
Use caution if
- Those seeking a proven, high-potency antioxidant with extensive human studies
