Mild to moderate fine lines, uneven texture, enlarged pores. You have used retinol before or your skin tolerates active ingredients well. This concentration begins measurable collagen stimulation.
At 2,000 IUs, Level 2 upregulates Type I and Type III procollagen gene expression — the transcriptional signal that tells fibroblasts to produce new collagen. Simultaneously, it suppresses MMP-1 (collagenase) and MMP-3 (stromelysin), reducing collagen degradation. The net effect: more collagen produced, less collagen destroyed. Niacinamide strengthens the barrier. Sodium Hyaluronate maintains dermal hydration during accelerated epidermal turnover. pH-optimized for stability and penetration.
Weeks 8–16: fine line softening, pore reduction, measurable collagen stimulation (PICP levels), texture improvement. Mild adjustment period of 1–3 weeks is pharmacological evidence that the retinoid cascade is activating.
Apply nightly to clean skin before any other treatment. Consistency drives cumulative gene expression changes — daily use is essential. Pair with THD-Ascorbate Vitamin C Serum for complementary collagen support and broad-spectrum SPF 30+ daily.
