HPR Isn't New. So Why Does It Suddenly Feel New?

If you've been seeing HPR pop up in skincare lately, you might assume it's the newest retinoid on the block.

But here's the surprising part: HPR isn't new.

In fact, it's been around for well over a decade.

So why are we suddenly seeing it appear in more skincare products — especially products positioned as a gentler alternative to traditional retinoids?

We got curious.

First, what is HPR?

HPR stands for Hydroxypinacolone Retinoate.

It's a type of retinoid, which puts it in the same vitamin A family as retinol, retinal and retinoic acid. But HPR takes a slightly different route. With retinol, your skin needs to convert it:

Retinol → Retinal → Retinoic Acid

Retinal is already one step closer:

Retinal → Retinoic Acid

HPR is different. It can interact with retinoid receptors without needing to go through the same conversion pathway.

And that's one of the reasons it's getting attention.

Fewer steps doesn't automatically mean “stronger” — but it does make HPR an interesting retinoid to watch.

So why haven't we heard about HPR before?

This is the part we found most interesting.

HPR has actually been around since at least the late 2000s. It wasn't invented yesterday. So what changed?

The technology around it.

HPR has some formulation challenges. Like many retinoids, it needs to be formulated carefully to remain stable and usable in a finished skincare product.

Over the years, formulators have developed better ways of working with difficult ingredients — from improved delivery systems to better ways of keeping ingredients stable inside a formula.

And that matters.

Because an ingredient can be promising on paper, but if it's difficult to formulate well, it's much harder to turn it into a reliable everyday skincare product.

HPR also has an interesting stability advantage

Retinoids aren't exactly famous for being easy-going ingredients.

Light, heat and time can all affect them.

Research comparing different retinoids in cosmetic products found that HPR showed particularly good stability under the conditions tested. But there's an important catch: the stability of the finished product still depends on the formula and how it's stored.

So we're not going to tell you:

“HPR is exactly 30× more stable than retinol.”

You'll see claims like that in skincare marketing, but there isn't one universal number that applies to every HPR product.

What we can say is:

HPR has shown promising stability — and that could be one reason it's becoming more interesting to formulators.

What about sensitive skin?

This is probably THE MOST exciting part.

Retinoids can be incredibly useful, but they're also famous for causing dryness, peeling, redness and irritation, particularly when you're starting out.

HPR is often described as a gentler retinoid, and some studies have reported good tolerability.

That makes it particularly interesting for people who:

• are new to retinoids
• find retinol irritating
• want to introduce a vitamin A derivative more gradually
• have sensitive skin but still want to explore retinoids

But there's an important distinction:

Gentler doesn't mean irritation-free.

HPR is still a retinoid. Your skin may still need time to adjust.

And compared with established retinoids, we simply don't have decades of research behind HPR yet.

So, does HPR actually work?

The early answer looks promising.

HPR has been studied for things including acne, skin texture and signs of ageing, and newer research is continuing to explore its potential. 

What's particularly interesting is that HPR research is still happening now.

So while HPR isn't new, our understanding of it is continuing to develop.

And that's perhaps why we're hearing more about it today.

HPR vs Retinol vs Retinal

Here's the simple version:

So should you immediately ditch your retinol for HPR?

No.

Retinol has a much longer track record, and retinal is also becoming increasingly popular for good reason.

HPR is simply another interesting option.

So… is HPR worth the hype?

We think it's worth watching — but not because it's “the new retinol.”

HPR has actually been around for years. What's new is the attention.

Better formulation technology, growing interest in gentler retinoids and new research are giving HPR another moment in the spotlight.

And if you're someone who has always wanted to try a retinoid but has been put off by irritation, HPR is certainly an ingredient worth knowing about.

Our take?

Promising? Yes.

A miracle ingredient? No.

Better than retinol? We don't know yet.

Interesting for sensitive skin? Absolutely.

Sometimes an ingredient doesn't need to be brand new to become interesting.

Maybe HPR is simply having its moment — more than a decade late.

A little HPR cheat sheet

HPR = Hydroxypinacolone Retinoate

A retinoid that can interact with retinoid receptors without following the same conversion pathway as retinol.

Why people are interested:
Potentially good tolerability + promising stability + growing research.

Who might find it interesting:
Retinoid beginners, particularly those looking for a potentially gentler option.

What to remember:
HPR is promising, but it's still the newer kid compared with retinol and prescription retinoids.
