Your skin has different needs during the day and night. During the day, protection from UV rays and pollution is crucial (sunscreen, antioxidants). At night, skin focuses on repair and regeneration (retinoids, peptides). Using targeted products for each time enhances effectiveness and reduces irritation.

Wash your face with a gentle cleanser and wait 30 minutes without applying products. If your skin feels tight and flaky → dry; if you notice shine all over → oily; if only the T‑zone is shiny and cheeks are normal/dry → combination; if it feels comfortable and balanced → normal; if you often experience redness, stinging or reactions → sensitive.

Sunscreen is the single most important anti‑aging step. UV rays cause up to 90% of visible skin aging. Apply a broad‑spectrum SPF 30+ every morning, rain or shine, and reapply every 2 hours if exposed to direct sunlight. It also prevents hyperpigmentation and skin cancer.

Yes, you can use different brands as long as the active ingredients work well together. Avoid layering strong acids (AHAs/BHAs) with retinoids or vitamin C at the same time to prevent irritation. Always introduce new products one at a time and patch‑test.

Avoid fragrance (parfum), essential oils, high concentrations of exfoliating acids, and SLS (sodium lauryl sulfate). Look for soothing ingredients like centella asiatica, ceramides, allantoin, and niacinamide (5% or less). Always choose mineral sunscreens with zinc oxide.
