How to Decode the Lingo on Skincare and Beauty Products: What is merely marketing “Hype?”

Cosmetic Chemist David Petrillo Available to talk about beauty product ingredients, and buzzwords like “glass skin,”  “patented technology,”  “cosmeceutical,”  “paraben-free”  etc..



Each season, a new crop of beauty trends, buzzwords, and marketing terms arise. Consumers are left to try to decode what actually works and what is jargon. If you are working on stories about ingredients or the beauty industry, such as the rise of K-Beauty products, the latest TikTok fad, or DIY skincare, David Petrillo, a cosmetic chemist and CEO and founder of skincare company Perfect Image, can provide exclusive answers to your questions by your deadline.


Mr. Petrillo can also dive deep into questions about what marketing and buzz words really mean, and if a certain product can achieve the results consumers seek. Such phrases include “glass skin,” “dewy skin,” and even “hydrated.” What do these mean, and how do we select appropriate skincare to achieve our desired results without being betrayed by marketing hype?


David Petrillo shares phrases consumers should know more about:


Patented Technology

This is a marketing term used to provide, sometimes falsely, a sense that the consumer is buying something that is highly innovative. But patents aren’t necessarily a surefire sign that something is groundbreaking. Patents are sometimes authorized based on a technical change rather than a scientific breakthrough meaning new combinations of ingredients or methods of production can be promoted as being “patented technology.” What consumers really want to do is identify what their skin needs and buy products with ingredients that are proven to effectively improve the skin in that area.


Maximum strength

This is a term used often by skin cleansers and moisturizers. But this is a relative term, and consumers don’t exactly know what the maximum strength entails or how the product benefits their skin more than the competition.


Clinical strength


FDA Cleared

The FDA has different protocols for skincare products that make cosmetic claims as opposed to those that make more medical claims, such as promising to increase the production of collagen in the skin. Since that is a body function, the FDA treats those differently than normal skincare products. However, the FDA just stipulates that the product being sold is safe to use in the manner in which it is directed to be used. FDA approval is not a credential that shows the superiority of results.



Products and consumers often use hydrating and moisturizing interchangeably, but this is inaccurate. If you want to hydrate your skin, this means you have skin that has become dull and possibly dry — you need a humectant such as hyaluronic acid or glycerin to draw water to the cells. If you need to moisturize your skin, you need a moisturizer that seals water in to prevent water loss. Today there are a variety of moisturizers, especially gel moisturizers, that have components that are both moisturizing and hydrating. These are good, but your choice of product depends on the individual condition of your skin. If you have extremely dry or dull skin, you may need one product that performs one function very well, rather than a jack of all trades.


Glass skin

Glass skin is a buzzword that has emerged in recent years to describe the effect of Korean beauty products, which make the skin look hydrated, luminous, and smooth. Usually, because all those adjectives entail different steps in a beauty routine, one needs several products to achieve this look, including an exfoliator, a serum, and a humectant. But more and more, single products are claiming to bring about this effect — while they may fit well into a beauty routine, one product will have a difficult time hydrating the skin while also brightening it and exfoliating it to give it a smoother and even texture.
