Is multi-step Korean facial skin care advisable? Which of these is really necessary and useful for leaving?

In my opinion it is not advisable. For skin care, it is enough to use high-quality:

1) gel (or foam) for washing (for oily / combination skin) or cleansing milk (for dry);

2) tonic,

3) cream or serum.

And instead of Korean cosmetics, in which there are mostly not the best compositions, I advise you to use high-quality natural. Read more on my website under the tag "Natural cosmetics" - https://natural4.ru/tag/naturalnaya-kosmetika/

Korean cosmetics are really cool and for me it is best to take a ready-made set right away. If you want to take something from the Korean line, then look at the Some By Mi brand. He develops cosmetics for skin imperfections (rashes, pigmentation, eliminates oily / dry skin, hormonal problems, etc.). It's no secret that every girl dreams of looking 100%. Therefore, you will definitely like the remedies from Some By Mi. I advise you to purchase the Some By Mi AHA-BHA-PHA 30 Days Miracle Starter Kit https://www.lunifera.ru/nabor-po-uhodu-za-kozhej-some-by-mi-aha-bha -pha-30-days-miracle-starter-kit.html which includes: cleansing soap, acid toner, acid serum and acid cream. In my opinion, these are the most necessary tools that really work.
