Abstract:
Introduction: Niacinamide or Vitamin B3 is water-soluble vitamins when apply niacinamide can reduce the loss of water and help to increase moisturize the skin on the top of the skin. In addition, Niacinamide help to reduce wrinkles, redness and blemish to aging or the aging of the skin on the face, so we are protected with extracts from Niacinamide or Vitamin B3 help to anti-wrinkle, redness and various blemish. Niacinamide will stop the melanosome to reduce melanin in the skin barrier. Moreover, Vitamin B3 stimulates fibroblast fibers to synthesis of collagen, elasticity, tightening dermis skin and anti-wrinkle.
Objective: The comparative study of the efficacy of 5% Niacinamide with Placebo on facial skin elasticity.
Material and Methods: Twenty-nine Thai female volunteers, aged 35-45 years, were recruited to undergo the damage elasticity on the facial skin. The treatment included applying either 5% Niacinamide extract cream or placebo cream on facial skin both left and right side (randomly determined by the computer system).Volunteers received the said treatment twice a day for 12 weeks and after that dermatologists (who were not associated with the study) would evaluate the wrinkles by means of Rao-Goldman 5 point scoring scale, the measurement of skin elasticity using cutometer MPA 580.The evaluation took place at the following stages: pre-treatment, week 4, week 8 and week 12 after the treatment. The side effect evaluation took place on week 4, week 8 and week 12. Volunteers evaluated their satisfaction of increasing of elasticity and wrinkles reduction in week 12.
Result: Twenty nine volunteers completed the 12-week period study. By using Rao Goldman 5-point scoring scale and Cutometer as the measurement, the result revealed that wrinkles on the facial skin were significantly reduced/ improved in week 8 and week 12, respectively. Statistically, 5% Niacinamide extract cream resulted in significant increase (in comparison to placebo cream) of elasticity on facial skin (forehead, end of the eye lid, cheek and chin) in week 8 and week 12, respectively. Volunteers were satisfied with the significant reduction/improvement of wrinkle and increasing of elasticity on the facial skin (forehead, end of the eye lid, cheek and chin) by applying 5% Niacinamide extract cream. There were no side effects from the treatment.
Conclusion: The elasticity of the facial skin with 5% B vitamin extracts has a facial elasticity effect by the Rao Goldman 5-point scoring scale. The elasticity of the Cutometer significantly increases elasticity. Including, the volunteers were satisfied with the elasticity of the skin and without any side effects caused by the cream applied on the facial skin. Therefore, 5% B vitamin extracts can be used to maintain the elasticity on the facial skin that is safe to treatment.
