Effectiveness of Skin Lotion Products from Nelumbo nucifera Gaertn. Petals Extract

Abstract

Several parts of Nelumbo nucifera Gaertn presents many medicinal properties.  The petals extracts contain substances that stimulate the production of collagen and inhibits the activity of the tyrosinase enzyme. The objectives of this study were to 1) develop skin care lotion products from Nelumbo nucifera Gaertn petals extracts, 2) compare the levels of elasticity, and levels of melanin pigment in the skin before and after using skin care lotion products from Nelumbo nucifera Gaertn petals extracts, 3) compare the levels of elasticity, and levels of melanin pigment in the skin after using the basic formula product with the recipe mixed with Nelumbo nucifera Gaertn petals extracts, and 4) satisfaction assessment among using skin care lotion products from Nelumbo nucifera Gaertn petals extracts. The sample size was calculated with G*Power to be 34 people. The sample were obtained through purposive selection. Apply the lotion to the designated location for a period of 28 days. The results showed the development of the 4 formulas. The formula 4^th has a lotion with a smooth texture and caramel color, which does not have a bad smell, without microbial or fungal growth, nor creaming or cracking shown, and a pH value of 5-6. When measured with the Cutometer MPA 580, It was found that the elasticity level of the skin after using increased compared to before using the product, equal to 0.89±0.04 and 0.82±0.06, respectively (p<.05), and from measurement with the Mexameter MX 18, it was found that the melanin pigment level of the skin decreased after using the product decreased more than before using the product, equal to 54.03±10.52 and 71.12±12.39, respectively (p<.05). The elasticity levels of the experimental section were greater than that of the control section, equal to 0.89±0.04 and 0.84±0.05, respectively (p<.05), the melanin pigment level of the experimental section decreased more than the control section, equal to 54.03±10.52 and 71.50±12.66, respectively (p<.05). The overall satisfaction scores were at a high level (4.36±0.63). It can be said that this skin care lotion product is from Nelumbo nucifera Gaertn petals extracts can be a model for developing formulas or lead to further commercial development.
