My skin is really becoming dull day by day and I want to know which kind of product or oil I should use to get youthful skin. my friend advised me to use rosa mosqueta oil. i want to know how can it be applied to face? And please tell me for what else it can be used? Also tell me what are the precautions that I need to take? Is there any kind of artificial products that are used in making it? Please tell me as all this information will help me to make a wise decision.
