| Hemp Seed Oil | Squalane | |
|---|---|---|
| Typical Concentration | Apply 2-5 drops as a moisturizer or mix with other products. Cold-pressed, unrefined oil is dark green with a nutty scent. Suitable for oily and acne-prone skin. Comedogenic rating: 0 (non-comedogenic). Use within 3-6 months and store refrigerated. | Can be used pure (100% squalane oil) or in formulations. Apply 2-3 drops after water-based products. Can be mixed with moisturizer. Safe for morning and night use. Non-comedogenic rating: 0-1 (very unlikely to clog pores). |
| Application | Topical (pure oil). Cold-pressed, unrefined. Can also be taken orally as a supplement. | Topical (oil, serum, cream ingredient). Apply as the last step of skincare (after water-based products) or mix into moisturizer. |

Mechanism of Action
Hemp Seed Oil
Linoleic acid (55-60%) is key active — acne-prone skin has been shown to have 50% less in sebum compared to normal skin; deficiency may contribute to abnormal follicular keratinization and comedone formation. Topical supplementation normalizes sebum composition (linoleate is component of sebum triglycerides), reduces comedone formation, supports ceramide synthesis. GLA (gamma-linolenic acid, 2-4%) converts to DGLA, which inhibits pro-inflammatory leukotriene B4 synthesis (5-lipoxygenase competition) and is precursor to anti-inflammatory prostaglandin E1. 3:1 omega-6:omega-3 ratio considered optimal for skin. Natural vitamin E provides antioxidant protection. Comedogenic rating 0. Contains 0% THC/CBD. Ideal for acne-prone, inflamed, eczema-prone skin. Goes rancid within 3-6 months — store refrigerated.
Squalane
Squalane is the fully hydrogenated form of squalene—a C30 isoprenoid hydrocarbon. As a saturated branched-chain hydrocarbon, squalane forms a non-occlusive emollient film that fills intercellular lipid spaces and reduces transepidermal water loss (TEWL) by approximately 20-30%. Squalene comprises ~12% of human sebum (synthesized via mevalonate pathway); squalane's structural similarity confers high biocompatibility and minimal comedogenic potential. Hydrogenation of squalene's six double bonds eliminates oxidative susceptibility—squalene peroxidizes with UV exposure while squalane remains stable. Squalane penetrates the stratum corneum and may support barrier lipid organization. Plant-derived squalane (sugarcane, olive) is structurally identical.
Risks & Safety
Hemp Seed Oil
Common
Can feel slightly heavy for very oily skin. Goes rancid quickly if not stored properly.
Serious
None.
Rare
Very rare allergic reaction.
Squalane
Common
Essentially none. May cause breakouts in a small percentage of people despite low comedogenic rating.
Serious
None.
Rare
Allergic reaction is extremely rare.
Full Profiles
Hemp Seed Oil →
Cold-pressed from Cannabis sativa seeds, hemp seed oil has an ideal 3:1 ratio of omega-6 to omega-3 fatty acids — the ratio considered optimal for skin health. It is rich in linoleic acid (which acne-prone skin is deficient in), gamma-linolenic acid (GLA, a potent anti-inflammatory), and natural vitamin E. Does not contain THC or CBD. One of the best oils for acne-prone, inflamed, or eczema-prone skin.
Squalane →
A lightweight, non-comedogenic emollient oil derived from squalene — a lipid naturally produced by human sebaceous glands. Squalane (the hydrogenated, stable form) mimics the skin's natural oils, making it an excellent moisturizer that rarely causes breakouts. It softens skin, reduces water loss, and has antioxidant properties. Increasingly sourced from sugarcane and olives rather than shark liver.
