Petrolatum for Rosacea

The gold-standard occlusive moisturiser. Locks water into damaged or compromised skin better than anything else, accelerates barrier repair, and (in newer research) actively boosts your skin's own antimicrobial defences. Cheap, non-allergenic, widely recommended by dermatologists for very dry, compromised, or post-procedure skin and for slugging.

Why it works for Rosacea

Seals moisture into your skin, cutting water loss by about 99 percent, and helps your skin build up its own barrier proteins. A useful top layer in the gentle rosacea routine the guidelines recommend. It is tolerated in rosacea because it does not clog pores or irritate.

How Petrolatum works

Semi-solid hydrocarbon mixture that penetrates the intercellular spaces of the stratum corneum (not just the surface), reducing transepidermal water loss by ~99% while permitting normal barrier recovery. Also upregulates antimicrobial peptide and barrier-protein gene expression in keratinocytes.
