It rebuilds collagen in the dermis without injuring the surface of your skin. Here's the mechanism, in plain language.
Key takeaways
- No needles, no anaesthesia and no recovery period
- Safe for all skin types and most seasons
- Visible glow often after the very first session
- Works on face, neck, décolleté and hands
PRX-T33 is a professional treatment from the Italian dermo-cosmetic brand WiQo. Unlike most peels, its goal is not to strip the top layers of skin away — it is to stimulate the deeper layers while leaving the surface intact. That single difference is why it delivers glow and firmness with no peeling and no downtime.
Three ingredients, one reaction
The formula combines trichloroacetic acid (TCA), hydrogen peroxide and kojic acid. TCA would normally cause the skin to frost and peel — but here, hydrogen peroxide buffers that surface effect, allowing the acid to work in the dermis instead of the epidermis. Kojic acid calms the skin and helps control pigmentation.
The surface stays whole. The collagen-building signal happens underneath — that’s the whole idea.
What that means for your skin
By triggering controlled repair in the dermis, PRX-T33 stimulates new collagen and elastin. Over a course of sessions, skin becomes firmer and smoother, tone evens out, and pores and fine lines soften — while you carry on with normal life the same day.
