Retinol 0.3% by Minimalist

Clinical Retinol. Precisely Dosed.

Retinol is the most extensively studied topical anti-aging active in dermatology. At 0.3%, Minimalist's formula delivers meaningful clinical efficacy — sufficient to drive measurable improvements in collagen synthesis, cellular turnover, and MMP suppression — while maintaining tolerability for most skin types.

The Retinol Mechanism

• Collagen synthesis: Retinol is converted to retinoic acid in the skin, which directly stimulates fibroblast collagen production and inhibits MMP-1 (collagenase) — the enzyme that degrades existing collagen.
• Cellular turnover: Retinol accelerates keratinocyte differentiation and desquamation, improving skin texture, reducing pore appearance, and fading hyperpigmentation.
• Epidermal thickening: Chronic retinol use increases epidermal thickness, reversing the thinning associated with photoaging and intrinsic aging.

Protocol Integration

Use PM only. Begin with 2–3 nights per week and increase frequency as tolerated. Do not layer with high-dose vitamin C (L-ascorbic acid) or AHAs on the same night — use on alternating evenings. Pair with a barrier-supportive moisturizer to minimize retinol-associated dryness.

Retinol and copper peptides should not be used simultaneously — use copper peptides AM, retinol PM for optimal results without interaction.
