Petrolatum, also known as petroleum jelly, is a semi-solid mixture of hydrocarbons derived from petroleum. It’s widely used in skincare for its powerful occlusive properties, helping to lock in moisture and protect the skin barrier.
Breakdown of Terms
- Scientific Name: Petrolatum
- Chemical Composition: A complex mixture of saturated hydrocarbons (alkanes) with long carbon chains.
- Common Names: Petroleum jelly, soft paraffin, white petrolatum
Benefits in Skincare
- Moisture Retention: Forms a barrier on the skin to prevent water loss, making it highly effective for dry and dehydrated skin.
- Skin Protection: Shields the skin from environmental aggressors, like wind and pollution, and helps prevent chafing and irritation.
- Wound Healing: Creates a protective seal over minor cuts and abrasions, aiding the healing process by keeping the area moist.
- Soothing Irritation: Helps relieve discomfort from conditions like eczema and psoriasis by calming and softening the skin.
Common Applications
- Lip Balm: Used to treat and prevent dry, cracked lips.
- Skin Barrier: Applied to rough or dry areas (like elbows and heels) to soften and protect the skin.
- Makeup Use: Acts as a highlighter or brow tamer in a pinch.
- Post-Treatment Care: Often recommended after procedures like laser treatments or tattoos to aid skin recovery.
Safety and Considerations
- Purity Matters: Only use refined, white petrolatum labeled as USP grade or pharmaceutical-grade to avoid contaminants.
- Pore-Clogging Risk: While non-comedogenic, petrolatum can trap dirt or bacteria if applied to unclean skin, potentially causing breakouts for some people.
- Not a Moisturizer on Its Own: Petrolatum locks in existing moisture but doesn’t hydrate, so it’s best used after applying a water-based product.
Why It’s Important in Skincare
Petrolatum is a powerhouse ingredient for maintaining skin health, especially for dry, sensitive, or compromised skin. Its ability to create a protective barrier helps skin retain hydration, accelerates healing, and defends against external damage. When used correctly, it’s a versatile and effective staple in any skincare routine.
