i think you had your question about a simple routine answered already, and i highlighted the most essential products to have with an asterisk too, so i just wanted to write out the (generally accepted) order to put your products on:
1/ oil cleanser (or balm, wipes etc) to remove makeup if you use that.
*2/ gel/liquid cleanser, or if you use cleansing bars
3/ then if you’re using toners/serums, put them on in order of consistency - thinnest to most viscous. if you’re using something like the laneige cream skin, i’d put that at the end, even though it is thin, bc it’s cream based, most serums are transparent or cloudy so they’ll go before that.
*4/ moisturiser.
4.5/ you could sandwich in retinol cream here ONLY AT NIGHT (either
1: a thin layer of moisturiser, wait however long it says on the retinol you’re using to apply after skin care - has to be a fully dry face, then moisturise again after 20-30 mins,
2: same as before, without a last layer of moisturiser on top,
or 3: same as 2, but switch the order - retinol first on dry skin, moisturise after).
^the above is just about what works for your skin while on retinol. it doesn’t increase or decrease the actual efficacy of the retinol. for eg, i use the first method bc retinol makes my face too dry.
*5/ sunscreen. (or at night time a face oil if you’re using that. oil is always the last step, except if you’re sunscreen in the same routine, where sunscreen goes last).
for products:
oil cleanser: the face shop rice water bright
gel cleanser: bioderma sensibio
moisturiser: kiehl’s ultra facial cream, or pyunkang yul moisture cream (though tbh, i still haven’t found a perfect moisturiser)
sunscreen: krave beauty beet the sun (fav), or beauty of joseon
