Glossary
An oil cold-pressed from the seeds of the safflower plant (Carthamus tinctorius) that is available in two varieties: high-linoleic (approximately 75-80 percent linoleic acid) and high-oleic (approximately 75-80 percent oleic acid). The high-linoleic variety is preferred for skincare because linoleic acid directly supports the skin barrier.
High-linoleic safflower oil is one of the richest plant sources of linoleic acid, an omega-6 essential fatty acid that is a critical structural component of the skin barrier. Research has consistently shown that people with acne, eczema, and compromised skin barriers have lower-than-normal linoleic acid levels in their skin lipids.
Topical application of linoleic acid-rich oils like safflower directly replenishes these depleted barrier lipids. This makes high-linoleic safflower oil particularly beneficial for acne-prone skin (counterintuitive but supported by research), eczema-prone skin, and barrier-damaged skin.
Safflower was one of the earliest cultivated plants, grown in ancient Egypt for both its flowers (used as a red-orange dye) and its oil (used for cosmetics, lamp fuel, and cooking). Safflower garlands have been found in Egyptian tombs dating back to 4,000 years ago, and the oil was used in Egyptian skincare formulations.
The dye from safflower petals (carthamin) was used as a cosmetic rouge and lip color across ancient Egyptian, Indian, and Chinese cultures. This dual use (oil for skincare, petals for cosmetics) made safflower a complete beauty ingredient in the ancient world.
Research supports the use of high-linoleic oils for acne-prone skin. Studies have shown that acne-prone skin produces sebum lower in linoleic acid, and topical linoleic acid application can help normalize sebum composition. High-linoleic safflower oil has a comedogenic rating of 0, making it one of the safest oils for acne-prone skin.
High-linoleic safflower oil has approximately 75-80 percent linoleic acid (an omega-6, barrier supporting, lightweight). High-oleic safflower oil has approximately 75-80 percent oleic acid (an omega-9, deeply moisturizing, richer). For facial skincare, high-linoleic is generally preferred. For body care, either works well.
High-linoleic safflower oil, being high in polyunsaturated fat, is more susceptible to oxidation than high-oleic oils. Store in a dark glass bottle in the refrigerator and use within 6-9 months of opening. Adding vitamin E (tocopherol) as a natural antioxidant extends shelf life.
