The snail gel does the job of an occlusive, which is exactly what I wanted it for. I use the C serum morning and night, and I'm using the Retin A cream morning and night.
I always follow these steps,
Cleanse - double cleanse evening / Konjac sponge with a cleanser in the morning.
Actives - ingredients that do something, Vit C etc
Hydrators - moisturizers
Occlusive - snail gel morning / rosehip oil at night
Treatments - suncream etc
So, this morning I used a C cleanser with a Konjac sponge, a swipe of Mizon toner then my C serum. Later I used a Hyaluronic serum, then the Retin Moisturiser, touch of snail gel and some sun cream. Not that it was sunny but I use it every day I go out.
I have been following an Asian Beauty routine for months now and seeing brilliant results, plus it's something I enjoy.
I vary my steps and will use Niacinamide serum at night instead of C serum and I alternate my moisturiser too, according to my needs or just because I like to use different products.
