multi-purpose oil revisited

Once again, I completely forgot my blogoversary (sorry blog) and also didn’t post anything on here for a while. Mainly because WORK. Also because I didn’t have any interesting updates to add. The only recent change in skincare has been to return, now my skin is less dry, to meadowfoam seed oil. This has duly been updated here:

I’ve also updated the big main post on oils, first posted three years or so ago. That is, it’s about carrier oils (as opposed to fragrant / essential oils), used on skin mainly for moisturising. I also used the multi-purpose oil for makeup removal, pre-cleansing (especially with heavier sunscreen), body moisturising, armpit shaving, hair styling / frizz minimising, and I’ve probably missed a few other uses. For lots of stuff, anyway.

Here is the shiny updated post, same place as usual:

The main tweaks are organizational:

In that last section, this might be sorta kinda useful:

A FEW APPROXIMATE SUGGESTIONS FOR OILS, BASED ON KIND OF SKIN

A. A GOOD BASIC START FOR MOST SKINS

Look for: lighter-feeling oils; often with lower molecular weight. Check the latter in chemistry textbooks, Wikipedia, etc.

Examples, cheap and readily-available from supermarkets, and should be likely to be OK on many skin types:

  • meadowfoam
  • mineral
  • safflower
  • sunflower

B. OILY SKIN

Look for: light-weight oils, high in omega-3, and/or astringent.
Avoiding: omega-9 (monounsaturated fat), omega-6 especially if λ-linolenic acid (gamma-linolenic acid, GLA), so seed oils unless high linoleic.

Some possible oils to try out:

  • grapeseed
  • hazelnut
  • safflower (low-oleic: check ingredients on bottle)

C. SENSITISED DRIED SKIN

= skin that has become more sensitive and more dry, usually as a side-effect of things being used on it (Accutane, AHA, BHA, etc.); may also have damaged barrier
≠ sensitive dry skin, on which see item D below

Look for: light-weight oils, preferably high in omega-3, omega-6 OK if linoleic acid (LA).
Avoiding, to be on the safe side: nut oils; omega-9 (monounsaturated fat); omega-6 if λ-linolenic acid (gamma-linolenic acid, GLA), so seed oils unless high linoleic; astringency.

Some possible oils to try out:

  • meadowfoam
  • mineral
  • safflower
  • sunflower

D. SENSITIVE DRY SKIN

Some possible oils to try out:

  • avocado (heavier)
  • borage / starflower seed
  • canola / rapeseed (careful: patch-test, as allergies are not uncommon)
  • evening primrose
  • hemp seed
  • macadamia (heavier)
  • meadowfoam
  • mineral
  • olive (EVOO, heavier)
  • rice bran (light but not astringent)
  • safflower
  • sunflower
  • sweet almond

E. ROSACEA AND SEBORRHEIC DERMATITIS

Avoid: nut oils; omega-9 / oleic acid: emu, jojoba, olive oils (including derivatives such as squalane); seed oils unless high linoleic. Advice from people on MUA such as the great and good barbiH.

Some possible oils to try out:

  • mineral oil
AND ALSO, FOR ALL:
The following two things are different, but both may result in skin looking and feeling dry:
  • Dryness = oil production by skin
  • Dehydration = water retention

Skin may be any combination of  the two: dry and dehydrated, oily and dehydrated, oily and hydrated, dry and hydrated. And it can be any of them in different areas. And to different degrees.

On dehydration: hydrate skin (water is the basic way), use oil to trap that layer next to skin. Hydrators can help too: a.k.a. humectants, like glycerin, hyaluronic acid, etc. In the form of toners, waters, Japanese and Korean moisturising waters/lotions, gels, serums. The most basic hydrator: plain water.

    Excellent post, thank you! I’ve been experimenting with sunflower oil on horrible combination skin while overseas, which worked surprisingly well, and walnut oil, which I didn’t realise was a thing, and it turned out to be more of a fail (too heavy).
