Covalent Renewal Serum 0.2% Retinal
Encapsulated retinaldehyde night serum
A clinical-strength retinaldehyde serum formulated at 0.2% and stabilized by lipid encapsulation, so the active reaches skin intact and releases gradually through the night. Retinal converts to retinoic acid one step faster than retinol, delivering visible resurfacing with markedly less irritation than equivalent retinol systems.
Designed for medspa aftercare programs: begin two nights per week following your provider's treatment plan and build tolerance over four weeks. Squalane and bisabolol buffer the work while the active does it.
- 0.2% encapsulated retinaldehyde
- Squalane + bisabolol comfort base
- Fragrance-free, airless pump, 30 mL
- Introduce gradually; always pair with morning SPF

Layers well with everything
No pilling under sunscreen or makeup, which was my problem with the last two I tried. Sinks in before I have finished the other side of my face.

Finally something my skin tolerates
I have rosacea-prone skin and most actives leave me red for days. This one buffers well, especially layered under a ceramide cream. Slow and steady, but it works.

Does what it claims
Absorbs in seconds and layers cleanly under everything else. The only thing I would change is a larger size option.
