Pineapple juice is one of the rare fruit juices that contains so many different vitamins and minerals. The most abundant by many in pineapple juice is vitamin C, followed by vitamin B6, folate, thiamine, riboflavin and niacin. It contains only 1% of the daily recommended value of vitamin K, so it is considered to be a safe for juice for those who are on blood thinning medications. Pineapple acts as an exfoliating agent and unclogs acne pores. Pineapple fruit has some active principles with important effect on skin: Sugars and a-hydroxyacids (AHA). These active principles are responsible for its moisturizing and anti-ageing and skin lightening actions.
The a-hydroxyacids (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 flexibility regardless of the degree of cutaneous hydration. The use of AHAs gives better results than simple hydration; its action is more significant in cases of extreme dryness with visible hydrokeratosis. 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.
As per our study and tests conducted we have found that Pineapple extract used at a level of 2% – 3% starts giving the moisturization effect. Anti-Ageing & skin lightening effect is found at a min level of 6%- 8%. We found that at a level of 5% skin tightening effect is also observed. Fairness result is obtained at min 6% & in- combination with other extracts.
Please note that all the above results are observed on leave on products, wash off products may not give the same result.
