Week 1-2: Adjustment period What happens: Skin adapts to retinol (may see some peeling, redness) Peptides begin signaling collagen production Texture may worsen before improving (retinol purge) What to do: Stick with routine unless severe irritation Reduce retinol frequency if needed Increase moisturizer Week 4-6: Initial improvements What you'll notice: Smoother skin texture Reduced breakouts (if acne-prone) More even tone Skin feels firmer Less irritation as skin adjusts Peptide + retinol advantage: Smoother, more hydrated texture than retinol alone
