Body care
Oils don’t add water; they mainly block water loss. Moisturizers that work combine water-adding humectants with emollients and an occlusive. Clinical studies repeatedly show emollient-containing lotions or creams help dry or eczematous skin, but direct trials pitting a plain oil against a lotion applied to damp skin are sparse in this set of abstracts.
Myth Busting
Argan
Argan oil’s value for frizz is primarily cosmetic: its fatty acids and surface‑active lipids coat the hair, smooth the cuticle and add shine. The literature here shows compositional differences, processing effects, and antioxidant activity — useful context for styling — but not clinical proof that oil restores broken ends or structurally repairs hair.
Myth Busting
Castor oil
Castor-heavy oil cleansing can remove makeup and even affect drug penetration, but the notion that castor oil ‘‘draws out’’ toxins or reliably clears acne is not supported by the research cited here. Evidence for helpful effects is patchy and mostly lab or formulation-level.
Myth Busting
Rosehip
Many product pages call rosehip oil “nature’s retinol.” The papers supplied here show rosehip as a source of carotenoids, vitamin C, tocopherols and PUFAs and include small in‑vitro and animal studies of wound healing, hair growth and antioxidant activity. They do not, in themselves, establish that rosehip contains meaningful retinoic acid or that it reproduces the clinical effects of pharmaceutical retinoids.
