What Is Carthamus Tinctorius Flower?

Carthamus tinctorius flower, commonly known as safflower, is a flowering plant native to arid regions. The flower extract contains bioactive compounds including flavonoids and other polyphenols that give it both colour and potential skin benefits.

In skincare formulations, this ingredient primarily functions as a natural colorant, though the extract itself contains compounds with antioxidant and anti-inflammatory properties based on preliminary research.

How It Works

Carthamus tinctorius flower extract contains polyphenolic compounds that act as antioxidants, meaning they can donate electrons to unstable free radicals and render them harmless. This may reduce oxidative stress in skin cells.

The extract also shows potential anti-inflammatory activity in laboratory studies, though the mechanisms are not fully understood and research in human skin is limited. Additionally, some evidence suggests it may inhibit enzymes (collagenase and elastase) involved in breaking down structural skin proteins.

Clinical Evidence & References

Laboratory studies demonstrate that carthamus tinctorius flower extracts possess antioxidant and anti-inflammatory properties, and show no cytotoxicity to skin cells (keratinocytes and fibroblasts) at tested concentrations. The extract has been studied for its ability to inhibit enzymes involved in collagen and elastin breakdown.

However, most available research is conducted in vitro (in test tubes or cell cultures) rather than in human clinical trials. Evidence of efficacy in actual skincare products or on living skin is limited, so we cannot yet make confident claims about real-world skin benefits at typical cosmetic concentrations.

How to Use

This ingredient is used at very low concentrations in skincare products (found in roughly 0.1% of formulations). It functions primarily as a natural colourant, so you may notice subtle colour in products containing it. Use as directed by the product instructions—typically daily as part of your regular skincare routine if included in a moisturiser or treatment.

Safety & Precautions

Carthamus tinctorius flower extract is generally well-tolerated and shows no cytotoxic effects in studies. It is suitable for most skin types, though individuals with known plant allergies should check ingredient lists.
