Snail mucin and vitamin C

This is by preference. Normally thinnest to thickest. But i often go with the snail essence first because it's an essence, it's before the serum in my routine and despite the slimy and thick looking consistency it absorbed pretty fast for me. Normally. I have moments where i use vit c first because i heard somewhere that they work better against hyperpigmentation if they go first.

Yes, you can use these in the same routine. @lamvan gave the perfect answer for which product goes first. Personally, I'll use an essence first, and apply the serum once the essence is fully absorbed.

I would use vitamin C first on clean skin then snail mucin.

Yes, you can use vitamin C and snail mucin in one routine. Because vitamin C is an active ingredient for brightning and snail mucin is a hydrator. Usually skin care products are applied from thinnest (watery) to thickest (cream). So in your case the essence goes first, after which comes the serum.

they can be used together and the thinner one would go first. sounds like the essence is thinner and would be applied first
