Good afternoon!A few words about the human skin.There is such a thing as microbiocinosis of the skin, its purity depends on it.We have different pore widths, and we release different amounts of carbon dioxide and sebum through them.Those who have barely noticeable pores are lucky, in this case pathogenic bacteria on the surface of the skin have a minor harmful effect.It is necessary to take proper care of your face and body.I recommend Librederm cosmetics.The brand is relatively inexpensive.I've tried a lot.I liked the day cream with collagen, it does not grease the skin, it is well absorbed, powder fits well on it.I can't imagine a morning exercise without a face wash with hyaluronic acid or collagen.I like to alternate them, cleansing the skin becomes more effective.Of course, a tonic with stem cells is also in use.The smell of the products is gentle and very pleasant.Changing, supplementing, trying new facial cosmetics, Librederm remains indispensable for me.Thanks to the manufacturers for the high-quality product.Sincerely, Gordeeva E.V.
