What it is
A natural extract obtained from the fruit of Citrus aurantium amara (bitter orange), rich in flavonoids, vitamin C, and other antioxidant compounds.
How it works
The antioxidants in bitter orange fruit extract help neutralize free radicals that can damage skin cells. Its astringent properties come from natural acids and tannins that temporarily tighten skin and reduce the appearance of pores.
Pros
Antioxidant protection
Helps defend skin from free radical damage caused by pollution and UV exposure, which can contribute to premature aging.
Pore-minimizing effect
Its mild astringent action can temporarily tighten pores, giving skin a smoother, more refined appearance.
Cons and cautions
Potential irritation
Citrus extracts can cause stinging, redness, or burning, especially on sensitive or damaged skin.
Photosensitivity risk
Like many citrus ingredients, it may increase skin's sensitivity to sunlight, so daily sunscreen use is essential.
Best for
- People with oily or combination skin looking for pore-minimizing effects
- Those wanting a natural antioxidant boost in their routine
Use caution if
- Individuals with sensitive, reactive, or rosacea-prone skin
