Subcision is a process used to treat deep rolling scars left behind by acne or other skin diseases. It is also used to lessen the appearance of severe glabella lines, though its effectiveness in this application is debatable. Essentially the process involves separating the skin tissue in the affected area from the deeper scar tissue. This allows the blood to pool under the affected area, eventually causing the deep rolling scar to level off with the rest of the skin area. Once the skin has leveled, treatments such as laser resurfacing , microdermabrasion or chemical peels can be used to smooth out the scarred tissue. [ citation needed ]
I have already written a post on what Gurley meant and intended when he wrote this essay on the lifetime value model. In my blog post https:///2016/10/14/a-half-dozen-more-things-ive-learned-from-bill-gurley-about-investing/ I discuss issues like the game on the field problem. A “growth at virtually any cost” mentality can be dangerous and deadly for a startup. There is no hard and fast formula that determines the right level of paid spending on growth. High customer acquisition cost can quickly become uneconomic. The benefits of hyper growth eventually start to reflect an S curve most notably when the benefits of a network effects start to decline. At a point an additional user of a system no longer generates the same benefit it did when the company was smaller and had fewer users. For example, an incremental new user when you have only thousands of customers is worth far more than when you have millions of customers. Growth is still important but hyper growth driven by an outsize paid customer acquisition cost is no longer financially supportable. The goal of a business at that point should be greater organic growth driven by the sticky and viral growth engines.
