What is different about this stage

Turnover slows and the first cumulative sun damage becomes visible, often alongside breakouts that never fully left.

What dehydration (water-poor skin) looks like here

Skin that is short of water rather than short of oil — tight after cleansing, fine crepey lines, yet still shiny by midday.

Ingredients to lean on

💧 Hyaluronic Acid💧 Glycerin🫧 Polyglutamic Acid (PGA)🌾 Beta-Glucan💠 Trehalose
⚠️ Be careful with: High-strength alcohol toners and long hot showers
💡 Tip: The Korean distinction worth learning: dry skin lacks oil, dehydrated skin lacks water, and oily skin can absolutely be dehydrated. Layer humectants onto damp skin, then seal.
