Propanediol is a lightweight humectant—a molecule that draws water into the skin to keep it hydrated. It's also used in cosmetic formulations as a solvent and preservative booster, helping products stay stable and feel smooth on the skin.
Benefits
Hydrates and moisturizes the skin
Improves product texture and spreadability
Helps preserve formulations naturally
Science: Propanediol can be produced through bio-based fermentation (from glycerol using microorganisms), making it an environmentally friendly alternative to traditional chemical synthesis. It is widely recognized as safe in cosmetic and food applications, with established use as both a humectant and preservative enhancer.
Resveratrol is a natural antioxidant compound found in grapes, berries, and red wine. In skincare, it works to neutralize free radicals caused by UV damage and environmental stress, helping to protect skin from premature aging and maintain overall skin health.
Benefits
Antioxidant protection against UV damage and environmental stressors
May help reduce signs of photoaging (sun damage)
Supports skin cell repair and regeneration
Science: Research indicates resveratrol is effective as a topical cosmeceutical for treating photodamaged skin, with evidence ranging from high-quality Level I to Level II studies. It works synergistically with other antioxidants to neutralize free radicals and repair environmentally damaged skin cells.
Ferulic acid is a natural antioxidant compound that protects skin from free radical damage caused by UV light, pollution, and environmental stress. It works by neutralizing harmful molecules and boosting your skin's own protective enzymes, helping to prevent signs of aging and uneven skin tone.
Benefits
Antioxidant protection against free radicals and environmental damage
May help reduce signs of photoaging and UV-related skin damage
Can help even out skin tone and reduce hyperpigmentation
Anti-inflammatory properties
May support skin barrier health by protecting collagen and elastin
Potential concerns
Stability concern: ferulic acid oxidizes quickly when exposed to air or light, which can reduce its effectiveness over time
Limited data on long-term use in cosmetics; most research is preliminary
Rare sensitivity possible, though toxicity is considered low
Science: Research confirms ferulic acid is a potent free radical scavenger with protective effects on skin structures like collagen and fibroblasts, and is recognized as an effective photoprotective and skin-brightening agent. However, its rapid oxidation in formulations limits practical effectiveness, and most human clinical data remains limited compared to established ingredients like vitamin C.
