The Retinol Authority

Induction Therapies didn't discover retinol when it became popular. We built formulas around it, developed protocols around it, studied it, and learned how skin adapts to it.

Pro Plant XO pads: Plant Exosomes with All-Trans Retinol at 4.0% and 8.0%, yellow with retinol, in a glass petri dish
Induction Therapies product range including Y.E.S.S.

Retinol is an ingredient. Retinol formulation is a discipline.

Y.E.S.S.® pairs encapsulated 1% All-Trans Retinol with trichloroacetic acid and hyaluronic acid. The retinol is the ingredient. Keeping it stable, tolerable, and effective beside an acid is the formulation.

From storage form to active form · select a step

Where we formulate

The alcohol form of vitamin A (C₂₀H₃₀O, 286.46 g/mol) and the reference form vitamin A is measured against. Two oxidation steps from the active form, which moderates activity and supports tolerance.

What decides how a retinol performs

Y.E.S.S.®
All-Trans Retinol, not an ester.

Esters need an extra conversion step and carry less retinol by weight. We formulate with All-Trans Retinol, the reference form of vitamin A.

Why we chose microencapsulation before it became a trend

Retinol rarely fails because it doesn't work. It fails because patients stop using it.

Build tolerance. Build strength. Build results.

Stronger skin can tolerate more sophisticated skincare. The provider sets the pace, and many patients stay at maintenance for years.

What do you really know about retinol?

You prescribe it. Recommend it. Maybe even use it every night. But how well do you actually know retinol?

Inside the formula

We formulate around two outcomes at once: retinoid activity and skin tolerance.

Pro Plant XO pads, yellow with retinol
Pro Plant XO pads, 4.0% / 8.0% All-Trans Retinol.

Retinol carries four conjugated double bonds, all in the trans configuration. UV (absorption peak near 325 nm) and heat can twist them into cis isomers. Pure retinol is pale yellow: the color of these Pro Plant XO pads is the retinol.

Clinically studied: Y.E.S.S.® and PRX⁸
