The extract made from pineapples (Ananas comosus) has a variety of positive effects on the skin and promotes skin elasticity while removing dead damaged skin, while improving hydration and moisture and promoting a more elastic and clear looking skin.
Cosmetic Properties of Pineapples
Pineapple fruit has some active principles with important effect on skin—sugars and a-hydroxy-acids (AHA) as well as enzymes.These active principles are responsible for its moisturizing and anti-ageing action, and also have an antifungal and purifying effect on the skin.
In studies it was also shown that bromelain, contained in pineapples, also has a strong anti-inflammatory action and has a positive effect, interfering with the growth of malignant cells and tumors.
The a-hydroxy-acids (AHA) are a group of organic acids that work on the corneal layer and reduce the cohesion of the corneocytes. The result of the application of AHAs is a thinner corneal layer, which improves its elasticity and flexibility regardless of the degree of skin hydration.The use of AHAs gives better results than simple hydration; its action is more significant in cases of extreme dryness with visible hydro-keratosis.
The sugars and derivatives form hydrogen bridges with the water on the surface of the skin, retaining it and thus maintaining the moisture of the horny layer to enhance the elasticity, resilience and softness of the skin.Two newly discovered enzymes found in pineapple are also highly effective in removing damaged skin (debridement) as was shown when tested in burn trauma.
Traditional Use of Pineapples
In Africa, the dried, powdered root is a remedy for edema.
