What it is
A natural extract derived from the aerial parts (flower, leaf, stem) of Dianthus carthusianorum, a flowering plant in the carnation family. It contains various plant compounds, including flavonoids and phenolic acids, which are known for their antioxidant activity.
How it works
The extract works primarily by providing antioxidant compounds that can neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also have mild anti-inflammatory effects, helping to soothe irritated skin. In a formulation, it acts as a skin-conditioning agent, contributing to the overall protective and calming profile of a product.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without irritating sensitive skin, making it a good option for daily use.
Soothing potential
May help calm redness or irritation, offering a comforting addition to products for reactive skin.
Cons and cautions
Limited research
There is very little published research on this specific extract for skincare, so its benefits are less proven compared to well-studied antioxidants.
Variable potency
The concentration of active compounds can vary widely between batches and suppliers, leading to inconsistent results in products.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- People with sensitive or reactive skin who want to avoid harsh ingredients
Use caution if
- Those with known allergies to plants in the carnation family (Caryophyllaceae)
Usage tips
Safety summary
Considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible in individuals sensitive to carnation-family plants. As with any new ingredient, a patch test is recommended.
