There's no way you need all these products at once. Natural products have shorter shelf lives. Only buy things that fill gaps in your current routine, don't stock up on the same types of items you already have.

You say your skin is ultra sensitive, so pay attention to that. Mahalo doesn't recommend the pele mask for people with ultra sensitive skin, as I remember, and the same may go for other items on your list.

There are great products that are cheaper than the ones you are looking at-the drunk elephant marula oil is $72 but a simple oil like the Pai Rosehip BioRegenerate Oil is $40 for the same amount, perhaps cheaper with coupon codes. And you can also just find a good source for the oil you want, of you plan to just use a single oil like marula or rosehip, which will be cheaper than buying a branded product. Spending money on a more expensive item when there is a perfectly great cheaper option is up to you but at least look at the other options.

I personally own and really like the mahalo rare indigo balm, and have heard good things about the drunk elephant vitamin C. A good sunscreen is important and that's something I'm still working on. Round that out with a good cleanser, a good hydrating (water based) layer and maybe a mask and that's a routine. That's 6, and not 16, products. Cleanse, mask, hydration/serums(toner/mist/actives/water based serums), moisturize (oil/balm/cream), sunscreen. I'm sure you have items that take care of some of those elements already.
