Japanese to English Other Cosmetics, Beauty

**Please be aware that there is the possibility that this is not exactly the right word: I am dealing with a hard-to-read hand-written document, so I may not be reading some of the words right.**

This is a beauty diary, of how a woman takes care of her skin. She is describing how she washes her face, etc.

きめの細かいあわで洗いしっとり洗いあがる。
２０分位バッティング（パッティング？）が理想　しっとりします
くすみ…出ししみが消えてきてます
かさっきをおさえて水分がにげなくなります。
美容液
乳液
クリーム

In かさっき, the か, っ, and き are clear, but I am not sure about the さ. It could be another hiragana letter.

What is かさっき?

Thanks.
