Rento

Rento is a Finnish sauna-lifestyle brand owned by the family business Tammer Brands, describing itself as rooted in authentic Finnish sauna culture. Its collection spans sauna accessories, textiles, scents, and cosmetics, carrying the Design from Finland label and, for domestically made products, the Key Flag mark. The Arctic Pine Peat Mask, part of its longer-running product line, combines Finnish peat with pine extract and is applied during a sauna session so heat aids absorption.

Rento is a Finland brand built around whole peat and pine extract.

Peat from Finland is mainly sphagnum peat (raised bog) and carex peat (fen). Peat — the organic sediment itself — is used in treatments like peat balneotherapy, peat body wraps, and peat mud pack, most often explored for psoriasis, back pain (chronic low back pain), joint inflammation (osteoarthritis, rheumatic conditions), and eczema (atopic dermatitis).
