Some moisturizers are formulated to feel "cosmetically elegant" on the skin, which means they're lightweight, nongreasy, and somewhat unnoticeable. Products which are like this usually don't moisturize well since the after-feel is taken more into consideration. Some people say that you should use more moisturizer to compensate for the reduced hydration capability, which results in a ridiculous amount of moisturizer. Yet after applying multiple layers of product, the skin doesn't feel any more hydrated. The issue is the product formulation. Yes, using more moisturizer provides more hydration up to a certain limit. So while 1 pump of lotion may be more hydrating than 1/2 of a pump, 2 pumps may necessarily not be more hydrating than 1 pump. I assume this "limit" is the maximum amount of product that our skin can completely absorb.

One more thing: the less product you use, the more it'll absorb into your skin. Because of this, I think it's necessary to find a product which is both lightweight (remember that lightweight products also absorb better than heavy products) and provides an insane amount of moisture with only a small amount. I'm on the hunt for this product. My goal is to recommend something that is exceptional. Stay tuned.
