An Aromahead field guide
Start with the carrier oil, not the essential oil. Most essential oils don't hydrate skin. Water does that. What oils do is help skin hold its moisture: calming inflammation, protecting the barrier, supporting healthy cell turnover. Rose otto, sandalwood, carrot seed, Roman chamomile, and geranium are our five for the face, at one or two drops per fluid ounce of carrier.
Commercial skincare leans on flashy claims. The honest version is narrower and more useful: hydration comes from water, and oils are what keep it from leaving.
Most essential oils don't actually hydrate the skin. They help your skin absorb and keep hydration by calming inflammation, protecting your barrier, and encouraging healthy cell turnover and circulation. That is why a facial oil goes on after your moisturizer, to seal in what is already there.
The Aromahead approach to skincareThe stratum corneum is your skin's first line of defense, locking in hydration and shielding against environmental stress. Rose otto has been shown to reduce transepidermal water loss, the measure of moisture escaping through that barrier.1
Fukada et al., 2012The same rose otto study found it prevented high cortisol, which matters for skin: cortisol can reduce ceramide production, break down collagen, slow the skin's repair process, and increase inflammation.1
Fukada et al., 2012Carrier oils are most of what you put on your skin, so they deserve the first decision. The essential oils are the accent, a drop or two, chosen for what your skin is doing.
Simmondsia chinensis
Technically a liquid wax, and the one we reach for most. It closely mimics sebum, the skin's own oil, so it balances oil production while calming irritation. Research supports its role in wound healing and in soothing skin affected by dermatitis and eczema. Sensitive skin tends to get along with it.2
Try it: the base for any facial serum or rollerArgania spinosa
Liquid gold: lightweight, silky, rich in vitamin E and essential fatty acids. It restores elasticity, calms irritation, supports the barrier, and is not known to clog pores. Still pressed by hand by Moroccan Berber women, which is part of why it costs what it does. You can even use it as a face wash instead of soap.3
Try it: 2 fl oz as a soap-free face washRosa × damascena
The gold standard for dry, mature, redness-prone skin. Antioxidants soften the look of fine lines. One drop is genuinely enough; a single drop takes 30 to 50 blossoms.
Santalum album
Soothing, cooling, and moisturizing, used above all for dry skin from moisture loss and for inflamed skin. A mild astringent, so it balances oil production too.
Pelargonium graveolens
Balances sebum by supporting surface circulation, which is why it suits oily and dry skin equally. Anti-inflammatory, and supportive of elasticity.4
Daucus carota
An excellent cellular regenerator, recommended for aged skin, dermatitis, irritation, rashes, and wrinkles. Note the carrier oil shares its Latin name; the essential oil is the one measured in drops.
| Oil | Latin name | Reach for it when | Best first method |
|---|---|---|---|
| Jojoba | Simmondsia chinensis | skin is irritated, or you don't know where to start | carrier: the base of serums and rollers |
| Argan | Argania spinosa | you want elasticity and barrier support | carrier: facial oil, or a soap-free wash |
| Rosehip seed | Rosa canina | scars and uneven tone are the concern | carrier: lightweight, blends into a glow oil |
| Pomegranate seed | Punica granatum | skin is mature or very dry | carrier: thick, blend with a silkier oil |
| Rose otto | Rosa × damascena | dryness comes with redness or fine lines | 1 drop per fl oz of carrier |
| Helichrysum | Helichrysum italicum | redness, blemishes, or a healing scar | 1 drop per fl oz, or its hydrosol on sunburn |
Skin is not one problem with one answer. The carrier does most of the work, the essential oil is an accent of one or two drops, and the routine matters more than any single bottle in it.
Skincare is a sequence, not a product. Each step does one job, and the oil goes last for a reason.
A mild cleanser, then a hydrosol mist or toner while skin is still damp. Hydrosols are the water layer, and most can be sprayed directly on skin with no dilution at all.
A water-based serum (aloe, glycerin, hydrosol) delivers hydration; the moisturizer holds it. Customizing a quality unscented lotion beats making one from scratch, because water plus oil needs real preservative chemistry.
Two or three drops of a carrier blend pressed in last, sealing the water-based layers under it. One or two drops of essential oil per fluid ounce is the whole dose for the face.
A butter mask for dryness, a clay mask for congestion, a sugar or salt scrub for texture. Never let a clay mask dry completely, and skip scrubs entirely while a sunburn heals.
Three from our classroom and blog, one for each layer of the routine. Every recipe links to its full walkthrough.
The sealing layer
Combine in a 1 oz bottle. Press two or three drops in after your moisturizer.
The full recipe on the blog →The water layer
Make it in a 1 oz (30 ml) bottle. No preservative, so make small batches and remake every couple of weeks.
The full recipe on the blog →For redness that keeps returning
Four drops of essential oil in a full ounce of argan: the face wants restraint. Pair it with a rose and helichrysum hydrosol spritz.

It had a lot of information and very easy to follow. It helped me to make my own skin care. Thank you so much.Sarvjeet G. · Making All-Natural Facial Products
I loved this course with all of the recipes and the in-depth information on specific ingredients. I appreciate you showing the oils and ingredients as you added them to what you were making.Summer W. · Making All-Natural Facial Products
I really enjoyed learning about more obscure oils, carriers, as well as the powders for exfoliation. The music during the blending was a nice touch!Melissa K. · Making All-Natural Facial Products
