Oil after moisturizer in extreme cold, and squalane is your best bet

For extreme cold, apply facial oil after moisturizer, and squalane is the most protective of the three you listed.

The logic is simple: moisturizer puts water and humectants into your skin. Oil seals that moisture in. If you put oil on first, you’re basically coating your face in a barrier that prevents the moisturizer from absorbing properly. Order matters: moisturizer → oil.

As for which oil, here’s the breakdown for extreme cold:

• Squalane – Best for cold. It’s molecularly very close to your skin’s own sebum, lightweight, and highly occlusive without feeling greasy. It locks in moisture and doesn’t freeze or thicken in low temps. It’s also non-comedogenic for most people.
• Jojoba – Good second choice. It’s technically a wax ester, so it feels similar to squalane but is slightly heavier. It still protects well, but in extreme dry cold, squalane handles wind and low humidity better.
• Rosehip – This is for repair, not protection. Rosehip is high in linoleic acid and antioxidants, great for fading scars or soothing irritation, but it’s less occlusive. In extreme cold, you want a barrier, not a treatment. Save rosehip for indoors or gentler climates.
