Korean women start anti-aging at 25 - a decade earlier than most Western routines. The philosophy: prevention is cheaper and more effective than correction.
**20s (prevention era)**: Focus on hydration + SPF + mild actives. Essentials: Pyunkang Yul Essence Toner, Beauty of Joseon Glow Serum, SPF 50+. Skip retinol until 26-28.
In-clinic 20s: Only annual checkup + LDM ultrasound facial ($120/session, 2-3x per year). No botox/filler/injectables.
**Late 20s-early 30s (maintenance era)**: Add retinoid (start with 0.25%, move to 0.5% Tretinoin), vitamin C, peptide serums. Sleep quality becomes visible.
In-clinic 30s: Rejuran 2-3x/year, Ultherapy or Thermage once every 18 months, mild botox 2x/year (glabella prevention only). Total ~$2,500-4,000/year.
**40s (correction era)**: Fuller treatment spectrum. Retinoid daily (prescription Tretinoin 0.5-1%), growth factor serums, peptides, vitamin C, ceramide-rich moisturizers.
In-clinic 40s: Thread lifting, HIFU/RF annually, fillers for midface volume loss, possibly mini-facelift conservative approach. Budget $5,000-15,000/year.
Key insight: Korean women who start at 25 often look like Western women 10 years younger at 45. Starting early = compounding benefit.
