Serum Sucks Won’t Stop Peeling
Water
Vegetable Glycerine 7.000 Urea 5.000 GDL 2.000 Biokelp Ferment 9.000 Sea Code 2.000 Sacha Inchi Oil 2.000 VItamin A 1.500 Natrasmooth 2.000 Apple Stemcell 2.000 Oatmeal 0.500 Panthenol 1.000 Magnesium 3.000 Matrixyl 3000 3.000 Ceremide Complex 3.000 Argireline 5.000 Tranexemic 2.500 GABA 1.000 DMAE 0.800 Green tea Extract 1.000 Leucidal 2.500 This serum formula keeps peeling and I can’t figure out why. I don’t heat this formula or add an emulsifier. -

First things first…. No preservative! (And don’t say leucidal.)
Can you define peeling? Your skin is peeling…or the product is flaking off your skin?
How do you expect water and oil to mix….without an emulsifier?
What form is the Vit A?
What is the pH?
What is it supposed to do?
Sorry….but being frank…this looks far more like a shopping list from a repacker …. than a formula.

As mentioned above, you need to introduce an emulsifier or a solubiliser (if you can reduce your oil concentration to below 1%), otherwise the oils will separate out of the rest of your formula pretty quickly.
Any dry materials such as the oatmeal which will swell and absorb water will then shrink and dry out when the water evaporates. If you used them at a high level, you would see a cracking powder on your skin, like clay! I would not advise the use of these in a leave-on formulation, but you may be able to improve the characteristics by introducing film-formers such as PVP or VP/VA.

Agree with what Graillotion said. Everything but the kitchen sink here. You need to simplify it. Keep the urea and one extract if you really need to have it. Probably keep GDL but make sure that the final pH is urea friendly.
