Rating (out of 5): 2

Dulse leaf (Palmaria palmata) has a long-standing history of traditional use in various cultures, especially within coastal communities of the North Atlantic, for general health and skin care purposes. Traditionally, dulse has been incorporated into topical preparations, baths, and diets, with the belief that its rich mineral content, including iodine, potassium, magnesium, and vitamins A and C, could nourish and improve skin health. Folk remedies have recommended seaweed baths, sometimes specifically with dulse, to soothe irritated skin, alleviate dryness, and promote a healthy complexion.

However, direct scientific studies evaluating dulse leaf’s efficacy for skin care are limited. Some research on seaweeds in general suggests antioxidant, anti-inflammatory, and moisturizing properties, which could theoretically benefit skin health. Dulse contains polyphenols and other bioactive compounds that may protect skin cells from oxidative stress and support skin barrier function. Yet, most available research has focused on other species of seaweed or has been conducted in vitro or in animal models, limiting direct applicability to human skin care.

In summary, while the use of dulse leaf for general skin care is rooted primarily in tradition and supported by its nutritional profile, robust clinical trials or direct scientific validation for its skin care benefits are lacking. Therefore, the evidence for its efficacy in this context is considered low to moderate and largely traditional rather than scientific.
