I used this product when I had multiple breakouts of acne on my chin before my period. Morning and night, this alone wasn't enough to moisturize my skin in the winter, so I added a little oil or cream. However, I think these two alone are quite moisturizing. What surprised me was that the emulsion isn't a lotion, but rather has a thick, clear, lotion-like texture, yet it's still deeply moisturizing. This alone seems fine for summer. It doesn't leave that weird shine that often occurs with thicker textures, and it blends in easily. It doesn't particularly speed up healing, but it doesn't irritate my acne. I think it's better to use it as a preventative. It seems like it's safe to use at any time, and with pollen season approaching, I'm thinking of buying the full version.
