DR ALTHEA 0.1% GENTLE RETINOL SERUM 30ML is a beginner-friendly retinoid treatment engineered to deliver anti-aging benefits with minimal irritation or sensitivity. The low 0.1% concentration provides effective collagen stimulation and cellular turnover while remaining suitable for retinol-naive or reactive skin types. This advanced formulation reduces the typical retinization period, allowing gradual adaptation without excessive dryness, redness, or peeling. The serum targets fine lines, uneven texture, and loss of firmness through proven retinoid mechanisms. Start with 2-3 times weekly application, gradually increasing frequency as skin tolerance develops. Apply to completely dry skin before moisturizer, avoiding eye area and sensitive zones. Use sunscreen daily during retinol treatment to prevent photosensitivity. The 30ml bottle supports consistent use in a professional anti-aging regimen.
