Potential therapeutic of olive oil industry by‐products in skin health: a review

Abstract

Olea europaea L. is one of the most important fruit trees in the Mediterranean countries due to its products, olive oil and table olives. However, the olive oil extraction industry produces large amounts of byproducts, such as olive pomace, leaves and olive mill wastewater, which are considered harmful to the environment, having negative impacts on soil, aquatic and air ecosystems. The olive oil industry byproducts are a major ecological issue mainly due to their phenolic components, such as oleuropein, hydroxytyrosol and tyrosol. However, olive oil industry by-products can be recovered, treated and studied for their health-promoting properties, holding great potential for the cosmetic and pharmaceutical industries. Furthermore, the recovery and treatment processes contribute to an efficient waste management and sustainability of the olive oil industry, leading to important economic benefits. The phenolic compounds extracted and obtained from these by-products present numerous health properties and can be used as antioxidant, photoprotector, anti-inflammatory and/or antimicrobial agents in wellness and therapeutics of the skin. This review highlights issues related to olive oil industry by-products and then proceeds to discuss how their beneficial biological activities make them reusable, particularly their high positive impact in treating skin disorders.

Extra Virgin Olive Oil Secoiridoids Modulate the Metabolic Activity of Dacarbazine Pre-Treated and Treatment-Naive Melanoma Cells

“…HTyr [ 71 , 72 ] and Tyr [ 73 ] are phenolic compounds specific to olive oil, while cinnamic acid [ 74 ], apigenin [ 75 ], and pinoresinol [ 76 ] are widespread and found in a great number of plants. All of these compounds are well known for their bioactive properties, such as antioxidant and antitumor activities, in addition to many others [ 77 , 78 ]. All analysed compounds were present in low concentrations, below 10 mg/kg.…”

From antiquity to contemporary times: how olive oil by-products and waste water can contribute to health

“…Cosmeceuticals are another interesting area of application for OMWW extracts. The strong antioxidant, anti-microbial, and anti-inflammatory properties of the OMWW fraction A009 offer protection from skin diseases ( Table 1 ), improved skin health and beneficial effects on the skin ageing process ( 33 , 42 ). An investigation of a biophenols extract, derived from an upcycling strategy using leftovers from the olive agri-food industry (from Olea europaea leaves and waste water), was prepared and tested as a cosmetic product and a dietary supplement ( 35 ).…”

Unlocking the potential of olive residues for functional purposes: update on human intervention trials with health and cosmetic products

“…Olive oil residues are of great interest to the cosmetic industry, with versatile applications. They contain bioactive compounds with high antioxidant activity, especially oleuropein and hydroxytyrosol, and boast a distinctive fatty acid profile along with an attractive mineral composition 26 . These characteristics endow them with anti‐ageing, anti‐inflammatory, and hydrating properties, making them promising active ingredients for cosmetic products (see Fig.…”
