PRX-T33 Skin Treatment in Chicago

PRX-T33 contains TCA (trichloroacetic acid) — the same ingredient used in deep chemical peels — but combined with hydrogen peroxide, which neutralizes the surface reaction. Standard TCA peels cause visible peeling and days of downtime because the acid works at the skin surface. PRX-T33 bypasses this by triggering the deep dermal stimulation without the surface damage. The result is skin tightening and collagen activation with no peeling and no downtime.

Most clients see visible improvement after the first session — skin looks firmer, brighter, and more even-toned immediately. A course of 4–6 sessions spaced 2 weeks apart produces the most significant and lasting results, especially for scars, stretch marks, or significant skin laxity. Monthly maintenance sessions sustain the collagen stimulation effect.

No. Unlike standard TCA peels, PRX-T33 does not cause visible peeling or significant redness. The skin may feel slightly tight for a few hours after the session. You can apply makeup and return to normal activity immediately. This makes PRX-T33 suitable for clients who cannot afford downtime — it is safe to do the day before an important event.

Yes — PRX-T33 is commonly combined with microneedling for enhanced results, especially for acne scars. The microneedling creates micro-channels that allow PRX-T33 to penetrate more deeply, amplifying the collagen response. It can also be used after HydraFacial or carbon peel on the same day. We recommend consulting with our specialist to build the right treatment sequence for your specific concerns.

PRX-T33 is effective for atrophic acne scars (the depressed type), post-acne marks, and uneven texture. The TCA component breaks down scar tissue while the collagen stimulation fills in depressions over time. For deeper or more established scars, combining PRX-T33 with RF microneedling produces faster and more significant results. A course of 4–6 sessions is typically recommended for scar treatment.
