What’s the best path to becoming a cosmetic chemist? It looks different for everyone but here’s Perry’s take. How did you get in the industry?

Let us know in the comments 👇

PDRN is getting a lot of attention in skin care right now.

And the marketing story is moving faster than the formulation reality.

That does not mean PDRN is useless. It may be an interesting ingredient, and there is research around related medical and skin applications. But a cosmetic product is not the same thing as an injectable treatment or a clinical procedure.

For formulators, the practical questions are pretty simple.

Does it survive in the formula?
Is it used at a meaningful level?
Does it improve the product compared with a formula without it?
Can consumers actually notice the difference?

Trending does not mean useless. But it also does not mean proven.

That is why the better question is not, “Is PDRN hot right now?” It is, “Does it make this formula better?”

Is AI sharing your formula?

That depends on the tool, the settings, and what you put into it.

A cosmetic formula can be confidential information. It may include ingredient choices, levels, supplier strategy, processing details, cost targets, and product direction. That is not something you should casually paste into any chatbot without thinking.

AI can be useful for formula review, troubleshooting, claim language, and ingredient research. But you need to understand the data policy of the platform you are using.

When in doubt, remove identifying details. Generalize the formula. Ask about the problem instead of handing over the whole development file.

AI can help formulators. But confidentiality still matters.

AI works for formulating, but there is a problem.

It can give you answers that sound reasonable, even when they are incomplete, impractical, or wrong.

That is not a small issue in cosmetic chemistry. A formula has to be stable. It has to be preserved. It has to be manufacturable. It has to meet claims, regulatory expectations, sensory targets, cost goals, and packaging requirements.

AI does not always know when an ingredient is incompatible. It may suggest unrealistic levels. It may miss processing details. It may give you a formula that looks fine on paper but fails in the lab.

So yes, AI can help formulators.

But every AI answer still needs a chemist asking, “Would this actually work?”

Can you customize a formula to save money?

Yes, but this is one of those areas where a shortcut can create a bigger problem.

You cannot just remove the most expensive ingredient and hope nobody notices. That ingredient might be helping with viscosity, sensory, stability, preservation, fragrance, performance, or claims.

A better approach is to look at the formula strategically.

What ingredients are driving cost?
Which ones are doing real work?
Which ones are label decoration?
Can you reduce levels without changing performance?
Can you use a second supplier?
Can you simplify the formula without hurting the product?

Saving money is possible. But good cost reduction still has to survive stability, performance testing, and consumer expectations.

AI formulators will not replace cosmetic chemists.

At least, not good ones.

AI can be useful. It can suggest starting points, summarize information, compare ingredients, and help you think through formulation options. But creating a real cosmetic product is not just writing a formula on a screen.

You still need to understand raw materials. You still need to make the batch. You still need to adjust the processing. You still need to evaluate viscosity, stability, odor, appearance, skin feel, preservation, claims, packaging, and cost.

A formula is not finished because AI wrote a list of ingredients.

The chemist is still needed to turn an idea into a product that actually works.

Is honey anti aging?

This is where cosmetic science gets a little less exciting than the marketing story.

Honey has interesting chemistry. It contains sugars, organic acids, antioxidants, and other materials that can have biological activity in lab tests. That does not automatically mean honey on your face will reverse aging.

A cell study can be useful. It can help researchers ask better questions. But it is not the same thing as a well controlled human clinical study on a finished cosmetic product.

So, is honey useless? No.

Is it proven to be an anti aging miracle? Also no.

That is the boring answer, which usually means it is closer to the truth.

07/22/2026

When is AI actually useful for cosmetic chemists?

Not when you ask it to “make me a perfect formula.” That is usually where the trouble starts.

AI is much more useful when you use it for specific tasks. Summarizing supplier information. Comparing ingredients. Drafting documentation. Brainstorming troubleshooting steps. Organizing stability data. Helping you think through what questions to ask next.

That can save time.

But it does not replace formulation experience. It does not replace lab work. And it definitely does not replace testing.

The best use of AI is not asking it to be the chemist. It is using it as a helper while you stay the chemist.

How do you make a formula smell better?

The tempting answer is, “add more fragrance.” But that is usually not the best first move.

If a formula smells bad, you need to figure out where the odor is coming from. Is it a raw material? A natural extract? A preservative? A surfactant? Is something changing during processing or storage?

Once you know the source, then you can decide whether to replace the ingredient, reduce the level, change the supplier, adjust the formula, or use fragrance more strategically.

Fragrance can make a good formula more appealing. But it is not a great solution for covering up a bad formulation decision.
