    Glides on my Skin

    This is the first time I have used a serum. The size is great I feel that it will last a while and is worth the try for the money. The mantra on the sides of all the products just astounds me and reminds me that this is it just a skincare routine but a soul care routine as well. It’s so smooth and silky that the formula has to be perfect for it to glide on as it does. I’m seeing some improvement in my pores and will continue to use it daily. Great product to try. It’s really great for my sensitive skin, no issues so far. Love ♥️ it

    Can I use this with the Truly Becoming serum? If so. Which do I use 1st?

    25 Months Ago

    You can certainly layer both serums, however, we find that the ingredients are optimized when worn separately. We recommend using Promise Serum during the day and Truly Becoming at night.

    Do I need to use this is I am using the multi benefit peptide serum? My goal is color correction?

    25 Months Ago

    The Truly Becoming Serum has a poly-peptide complex to visibly firm and improve skin tone. It also has multi-weight hyaluronic acid to keep skin deeply hydrated, plump, and smooth. This serum is perfect for anyone with normal, dry, dull, or ageing skin who needs ample hydration and is looking to improve the appearance of their fine lines.

    Can this serum be used in combination with a vitamin C serum. If so; which product should be used first.

    37 Months Ago

    Absolutely. The Promise Serum can be layered with other serums. Please note that we do not recommend layering more than two serums at a time to avoid diluting or neutralizing a serum's purpose.

    38 Months Ago

    You can elevate your skincare ritual by layering the Promise Serum with the Skin Transformation Cream and the Obsidian Facial Roller for an authentic Soulcare experience.
