Introduce

Hero ingredients for autumn

  • Retinal / retinol
  • AHA exfoliants (lactic, glycolic)
  • Tranexamic acid
  • Ceramides
  • Squalane
  • Peptides
  • Vitamin C (for pigment)
Retire

Lighten up these ingredients

  • Lightweight gel moisturizers (move toward creams)
  • High % BHA daily use
  • Pure clay masks (too drying as humidity drops)
Morning routine shift

Add vitamin C back at full strength (10–20%). Switch to a richer ceramide lotion. SPF 30+ stays, autumn UV is still meaningful.

Evening routine shift

Reintroduce retinoid 2 nights/week, building to 4. Layer ceramide cream on top. Add AHA once a week to lift summer pigment.

Environmental protection

Falling humidity, persistent UVA, wind exposure. Heavier moisturizer, daily SPF, lip balm becomes daily again.

SPF guidance

SPF 30 daily, UVA stays high through autumn even as UVB drops. Mineral or hybrid filter works well in cooler weather.

Supplements
  • · Collagen peptides 10–20 g/day (peak repair window)
  • · Vitamin D3 2000 IU/day (sunlight drops, skin repair needs it)
  • · Omega-3 EPA/DHA 2 g/day
  • · Niacinamide 500 mg/day (oral supports barrier and pigment)
