We pride ourselves in providing the highest quality products and services to our customers. Many of the oils offered will never change. Some oils may alter on occasion or vary slightly between batches. Several factors such as your mood, stress level, age, body chemistry, diet, and current medications should be considered when applying fragrance oils because it can affect the natural smell of your skin and the way a scent smells on you. In addition, other factors such as dry or oily skin can even affect the amount of time a fragrance will last after being applied.
