They aren't, even though there are two toners, they can be used together. In fact, if your skin isn't used to AHA, the barrier toner is good to apply with it.

The steps I'd recommend:
1. Cleanse (I like gentle milky or oil cleansers)
2. Toners. I'd apply the AHA/BHA first, and then the barrier toner, but you can do the opposite if you experience stinging.
3. Peptide serum
4. Moisturizer of your choice

AHA stands for alpha hydroxy acid, I'm not sure which one or ones specifically, but lactic and glycolic are common. They are excellent chemical exfoliators and increase cell turnover as well as help treat acne. They are real skincare powerhouses with multiple benefits. BHA is salicylic acid, which helps break down sebum in your pores to prevent blackheads.
🤣 no idea what I just bought but see $120+ marked down to $37 and trust for Costco = buy now ask questions later
Retinol + acid is a big nono. Everything else should be fine, but since u got a prescription id highly suggest (DEMAND😤) u ask ur doctor 👍

Are these products redundant? What steps are these applied?

Are you referring to MDSolarSciences mineral crème?
