What are your tips and tricks in using skincare?

I have recently been exploring and familiarizing myself a bit more within "our" Picky community and the platform itself. I came across this older discussion thread and found it very intriguing and informative. I learn so many wonderful things from others in this community! Could you please elaborate and explain what *7 Skin Method* is? Also, how do you put your sunscreen in a cushion casing? I am familiar with products in the cushion cases, although I have not yet used one personally. I know from what I have seen, the cushion cases are common with foundation, and also some other cream type products. Can they also be used for thick liquid products, such as a thick/heavy type of moisturizer or lotion? Whenever I am able to 'free up'some investment capital from our barely there budget we have right now, I am really curious about trying maybe a cushion foundation on blush! *I did notice the empty cushion cases are available in different styles/variations. I guess I just never realized or even really thought about that before! Of course I had to check out how and where to buy empty cushion cases! Lol! Happily, I discovered they are fairly inexpensive from YesStyle, Amazon, and a variety of other sellers. Seeing the empty cushion cases there, also showed a pictorial example at what appears to be very easy to put whatever product you want in it! I can't believe I had never known about this, but I am glad to have found out now! These things are just more examples of the many things I have learned as a result of Picky and all the awesome users who are part of this wonderful *Picky Family*! ----Thank you all SO much!
