This is a full bottle of the professional grade hyaluronic acid serum used for the Kate Somerville Dermal Quench Service at the KS clinic and spa in Beverly Hills-a service that would roughly cost you $300 if you were to select the bronze package. Fun fact—J-Lo owns one of these machines they use this serum for! The KS Dermal Quench Liquid Lift serum was created to mimic what this service offers in the convenience of your own home! It sells in retail for $110. What you are getting here is a highly concentrated form of hyaluronic acid-gentle enough for any skin type while effective enough to help reduce and eliminate signs of aging from the inside out, along with restoring the skin’s moisture barrier! This serum is an all in one product for many clients without the extra time for a complex regimen, or for the client looking to boost the brands/products they already love! Clinically proven to give results after the FIRST use- It’s an absolute luxurious addition to your skin routine that you cannot just buy anywhere!! **unused and packaged in an airtight bottle so product stays potent and can’t be manipulated by harsh lights **I’m selling my makeup artist kit in pieces-please let me know if you have an questions! And feel free to make an offer on any bundle for a great discount!
