Unfortunately for me, retin-a is not an item sold over the counter. The cosmetic version of retin-a is retinol. It is much less potent, but still claims to have much of the same anti-aging properties of retin-a. One of the most well know cosmetic retinol items on the market is Peter Thomas Roth's Retinol Fusion PM serum.
What it is:
A potent retinol serum that delivers skin-renewing benefits via optimally concentrated encapsulated retinol for maximum results with minimal irritation.
What it is formulated to do:
This technologically advanced combination of encapsulated retinol, and vitamins C and E, encourages the skin's renewal process with prime efficacy. It helps improve skintone and texture, assists in collagen production, and reduces lines and wrinkles to create a vibrantly youthful and healthy complexion. A dose of moisture minimizes redness and irritation, and mitigates the retinol's drying effects.
