Practicing Skin Longevity with ingredients—morning and night routines

Morning Routine (Protect)

1. Amino acid-based cleanser -- Gently removes impurities while preserving essential oils.

2. Toner (hyaluronic acid, glycerin) -- Delivers moisture to the stratum corneum and enhances absorption of subsequent steps.

3. Serum (vitamin C derivative APPS 1-3%, vitamin E) -- The antioxidant powerhouse. A shield protecting skin from UV and free radicals.

4. Moisturizer (ceramides, squalane) -- Reinforces barrier function and prevents moisture evaporation.

5. Sunscreen SPF30+ PA+++ -- The final step of the morning routine and the most important one.

Evening Routine (Balance + Support)

1. Oil-based cleanser -- Removes makeup and sunscreen without stressing the skin.

2. Mildly acidic cleanser -- Cleanses without disrupting the commensal bacterial balance, maintaining the skin's natural pH.

3. Toner (niacinamide 2-5%) -- Strengthens barrier function and provides anti-inflammatory benefits simultaneously.

4. Serum (peptide complex, fermented ingredients) -- Sends collagen synthesis signals and supports the commensal bacterial balance.

5. Ampoule 2-3 times per week (targeted) -- Intensive care tailored to the skin's current condition.

6. Moisturizing cream (ceramides, cholesterol, fatty acids) -- The three key intercellular lipid components that support overnight barrier repair.

The Different Roles of Morning and Evening

Morning focuses on "defense," while evening focuses on "recovery and strengthening." Peptides and fermented ingredients are best used at night, aligning with the skin's repair rhythm. And rather than following the exact same routine every day, adapting to your skin's changes is what truly matters.
