Dr. Graf Products diminished

What is happening with Dr. Graf’s skincare products? I loved her retinol serums and creams and it appears they are sold out of the retinol serums, very little inventory left. Is this because of the Holiday season or is she going to be no more on HSN? Everytime I like a brand, they remove it from their list of brands and start to dwindle down on the product line, this happened with Elysee as well. I hope they stock up on Dr. Graf’s products. I need my retinol at night time.
