Hemp Seed OilvsMandelic Acid

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.

Mandelic acid (152 Da, the largest common AHA) exfoliates through calcium chelation and corneodesmosome disruption like other AHAs, but its large molecular size results in slower, more even epidermal penetration with reduced risk of hot-spot irritation and stratum corneum over-exfoliation. Its phenyl ring confers partial lipophilicity, enabling penetration into the pilosebaceous unit and follicular infundibulum—unlike purely hydrophilic glycolic and lactic acids. Within pores, mandelic acid exerts mild comedolytic effects by disrupting keratinocyte cohesion in the follicular epithelium, similar to salicylic acid. It demonstrates antibacterial activity against Cutibacterium acnes (Propionibacterium acnes) through membrane disruption. Mandelic acid also inhibits tyrosinase and reduces melanosome transfer to keratinocytes, providing brightening benefits. This profile makes it particularly suitable for acne-prone skin, hyperpigmentation, and darker skin tones (Fitzpatrick IV–VI) where gentler exfoliation minimizes post-inflammatory hyperpigmentation risk.
