How do you layer SkinMedica’s TNS Advanced Serum?

I have been done a lot of research and cannot seem to get a definitive answer. Many advise to apply this serum right after cleansing and before other serums, while others advise other lighter serums to go on before the TNS. I typically alternate glycolic acid and retinol at night, for reference.
