Hi,
I am a beginner in the formulation (still doing more reading than formulating at the moment) and I came across this serum that claims they have 20% ascorbyl phosphate, 2.5% retinol, 2% salicylic acid and a bunch of other stuff. Is this even realistic to make all these ingredients play well in the same bottle? It is one of the bestsellers on Amazon and has raving reviews.

As far as mixing ingredients together, sure you can mix them together. That doesn't mean it will remain stable or effect (it won't). But consumers probably can't tell the difference so there won't be much negative impact on sales.

This product includes a lot of essential oils (irritants) and salycilic acid in addition to retinol. Skin will look awful after a week of this. Also they said ‘squalene’. It’s not stable, that’s why squalAne is used in cosmetics.
Water should be listed first.
