The science
The Regenerating Cleanser is a physically exfoliating cream cleanser, and its effects follow from three components: a mild emulsion base, a fine particulate abrasive and an essential-oil fragrance. The base is built on cetearyl alcohol with cetearyl and sorbitan olivate, olive-derived non-ionic emulsifiers with low irritation potential, propanediol as a humectant, sunflower and olive oils for emollience, and coco-glucoside and cetearyl glucoside as mild sugar surfactants at low levels, producing a cream that cleanses with limited lipid stripping and leaves an emollient residue; this is the mechanism behind the softness after rinsing. Prunus armeniaca (apricot) seed powder is the abrasive, milled to a fine particle size and suspended in the cream, which reduces the scoring associated with coarse, angular shell fragments; nonetheless, controlled work on physical exfoliation shows that frequency and pressure, more than particle refinement, govern barrier disruption, and daily use of any particulate scrub increases transepidermal water loss and irritation in a meaningful fraction of users, which corresponds to the tightness and flushing some reviewers report. Kaolin adds mild oil absorption.
The botanical exfoliants are not functionally active. Salix alba bark extract contains salicin, which is metabolised to salicylic acid systemically after ingestion but is not converted in the skin to a keratolytic degree; Spiraea ulmaria (meadowsweet) is a similar trace salicylate source; Lactobacillus/Punica granatum fruit ferment extract is marketed as an enzymatic exfoliant, and proteolytic activity in a thirty-second rinse-off is negligible. The soothing and antioxidant set, arnica, borage, calendula, alfalfa, elderberry, magnolia bark and tocopherol, contributes at minor levels, with Arnica montana a recognised sesquiterpene lactone sensitiser.
The tolerance considerations are the abrasive on inflamed, acneic, atopic or rosacea-prone skin; Citrus paradisi (grapefruit) oil at the seventh position and Citrus aurantium (bergamot) peel oil lower down, with limonene, linalool and pinene declared, essential oils whose oxidation products are frequent contact sensitisers and whose phototoxic potential, chiefly bergamot's, is largely mitigated by rinsing; and a trace of alcohol as a solubiliser. The formula is COSMOS-certified, vegan, silicone-free and free of acids and retinoids, and is suitable in pregnancy subject to essential-oil tolerance. The brand's single-use self-assessment panel supports the immediate brightening and smoothing claim; no independent or longer-term study exists.
