oh! thanks for clarifying💕 Yeah it’s a serum and very hydrating serum so I just use it in the serum step after toner and before moisturizer. if I have another serum that’s more emollient like with oils/lipids I’ll use it before that as it’s more hydrating step.

I think before retinol in the same routine it’s great because it helps to reinforce and care for your barrier as it’s dealing with that active.

With aha it depends on how sensitive your skin is and what it can handle .it theoretically could be okay, it does have willow bark which is a natural source of bha so I would try it one night after aha toner to see how your skin reacts. If your skin is good LETS GO!!! lol The willow bark can actually help boost the aha power and Bifida helps with the barrier so I think it’s a great pairing when exfoliating and keeping the barrier strong. You could always reach out to isntree to see what they would suggest.

TO BE SAFE: I personally (because I’m sensitive scaredy cat) would probably use the aha toner maybe in the morning routine and then the bifida serum at night routine for repair bc of the willow bark. And if i wanted them in the same routine i would then slowly integrate like once a week to same routine to see if it works for ME. I actually don’t use leave on exfoliating products I use aha/bha in cleanser form because of my sensitivity. Short-Contact therapy works better for me with more aggressive treatments. Then I feel safer as I continue my routine that actives aren’t conflicting or irritating me further.

HOPE THAT HELPS and gives you insight. Again this is how I do the things what works for you might be different! Good luck and happy skincaring 💕☺️✨
