Mineral Oil (Paraffinum Liquidum) in summer: how to adjust

Using Mineral Oil (Paraffinum Liquidum) in summer: the season brings heat, humidity, sweat and peak UV, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.

The most effective occlusive in common cosmetic use, and the most unfairly maligned. Cosmetic-grade mineral oil is highly refined, chemically inert and rates as non-comedogenic in testing — the acne folklore comes from crude industrial grades, not from the ingredient in your cleansing oil. It hydrates nothing itself; it simply stops water leaving.

What summer does to your skin

Heat, humidity, sweat and excess oil call for lightweight, fast-absorbing layers and a high, re-applied sunscreen.

How that changes Mineral Oil (Paraffinum Liquidum)

Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. Mineral Oil (Paraffinum Liquidum) works on dryness & dehydration, damaged moisture barrier, flaking & peeling, and it is normally applied BOTH.
