Different paths, one goal: stronger, smoother, more radiant skin. Retinol is the dermatologist gold standard for cell turnover and wrinkle reduction. Bakuchiol, its plant-based counterpart, delivers similar benefits with less chance of irritation — ideal for sensitive or first-time users. Whether you want the power of retinoids or the gentleness of botanicals, PSA Skincare's renewal actives are designed to reset texture, tone, and resilience.
