Occlusive emollient made of purified hydrocarbons. Reduces transepidermal water loss by nearly 99% and restores the skin barrier after damage.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Reference occlusive with a broad clinical base. Dermatology studies show accelerated wound healing and barrier repair in atopic dermatitis and xerosis.
Petrolatum (Petroleum Jelly, Vaseline) is a mixture of saturated hydrocarbons from petroleum, refined through multiple stages. At pharmacopoeial grade (USP, EP, Ph. Eur. Pharmaceutical Grade) it is fully stripped of polycyclic aromatic hydrocarbons. Mechanism. Occlusive: forms a hydrophobic film on skin that reduces transepidermal water loss (TEWL) by 98-99%. Outperforms any other emollient on this metric (Loden 2003). Does not feed the skin from outside – it holds what is already inside. Where applied. Lip balms, infant diaper-rash products, hand protective creams, nipple-crack creams during lactation, post-procedure creams. In Spanish brands – La Roche-Posay Cicaplast B5, Bioderma Cicabio, ISDIN Nutradeica, classic Vaseline. Evidence base. AAD 2024 and NICE 2024 list petrolatum among first-line therapy for atopic dermatitis, xerosis, and diaper dermatitis. The Cochrane Review 2017 on paediatric atopic dermatitis confirms petrolatum-based emollients reduce SCORAD and prolong remission. After laser procedures and dermabrasion, petrolatum is part of standard care (AAD postoperative protocols). Safety. CIR confirmed pharmacopoeial petrolatum safety at concentrations up to 100%. EU Cosmetics Regulation requires USP/EP purity for cosmetic use. Hypoallergenic, non-comedogenic (Fulton score 0). No systemic absorption. 2010s controversy. Greenpeace and vegan brands criticised petrolatum as a petroleum product with PAH risk. SCCS 2020 differentiated: technical-grade petrolatum without full refining is carcinogenic (in Annex II EU); pharmacopoeial grade is safe and not classified as carcinogen. Only USP/EP petrolatum is allowed in EU cosmetics. Pregnancy and lactation – safe. Drug of choice for cracked nipples during breastfeeding (heals without removal before nursing; safe if the infant ingests small amounts). Suitable on the abdomen for stretch marks and on the face for dryness. Particularly suitable for. Very dry skin, atopic dermatitis, post-procedure recovery, hand protection in healthcare workers and those who work with water, tissue protection after laser resurfacing.
