The Retinol 0.5 is best suited for Oily or acne-prone skin – Helps regulate sebum and prevent clogged pores.  Normal to combination skin – Can tolerate moderate strength retinol (0.5%).  Mature skin – Targets fine lines, wrinkles, and uneven skin tone.  Retinol-experienced users – Those who’ve already used lower strengths (like 0.1% or 0.3%) and want to move up.  This product is not suitable for sensitive skin since the 0.5% concentration may be too strong and could cause irritation, redness, peeling, or dryness.  Dry or Dehydrated Skin because retinol can exacerbate dryness and compromise the skin barrier, especially without proper hydration and moisturization.  Damaged or Compromised Skin Barrier since using strong actives like retinol on skin with a weak barrier can lead to increased irritation and sensitivity.
