During the summer, we need to keep skin *hydrated* with water-based products that contain humectants which draw and keep moisture in the skin. The summer sun and time outdoors can dehydrate our skin causing it to produce more oil.
C1 with sun-safe distilled lemon smells like coconuts and sunshine! Coconuts and their derivatives are only used in wash-off products.
C2, C3 AM, Sunscreen are still store-bought products.
C3 PM is a 2x chemical exfoliation toner, with kombucha added to the mix. It will contain double the acids, but the volume will stay the same. This can be diluted with C3AM for daily acid toner or use 2x strength as an extra-potent exfoliation treatment.
The summer sun and time outdoors can dehydrate the skin causing it to produce more oil. I find that << C3 AM + multiple layers of M1 + sunscreen >> is often enough to keep my skin hydrated and moisturized all day during th hottest days of summer, so I'll be increasing the volume of M1 from 100mL to 240mL.
M2 and M3 are optional during the day when it's super hot and humid, but non-negotiable at night. I still like my skin to get the protection and nourishment it needs so it can regenerate during sleep.
