Hydroxypinacolone Retinoate (HPR)

What is the ingredient?

Hydroxypinacolone Retinoate (HPR) is an advanced retinoid derived from retinoic acid. Unlike traditional retinol, HPR is already in a bioavailable form and does not require multiple conversion steps within the skin to become active.

In skincare, HPR is used to support skin renewal and improve the appearance of texture and firmness over time.

How does it work?

HPR interacts directly with retinoid receptors in the skin. This helps:

• Support healthy cell turnover

• Improve the appearance of uneven texture

• Encourage smoother, more refined-looking skin

Because it bypasses conversion steps required by retinol, it allows for more controlled and predictable activity. When formulated with barrier-supporting ingredients, it can offer improved tolerability compared to traditional retinoids.

HPR supports gradual, long-term renewal rather than immediate visible change.

Own Time – where it forms the foundation of our renewal system, supported by bakuchiol, hydration molecules, and barrier cushioning lipids.

Why we use HPR at Flout

As skin matures, renewal slows and structural support declines. We include HPR because it:

• Provides direct retinoid activity

• Allows controlled performance within a supportive system

• Aligns with long-term skin longevity rather than short-term resurfacing

It reflects our approach of intelligent stimulation, balanced with barrier respect.
