Controlled release technology can change how cosmetic active ingredients are delivered after application. Discover how microcapsules, polymeric microspheres, liposomes and silicone-based systems can protect actives, manage compatibility and control their release over time.

Surfactants do far more than create foam. Discover how surfactants help cleanse, emulsify, wet, solubilise and stabilise cosmetic formulations, and why choosing the right surfactant system is critical for performance, mildness and skin feel.

How can you prove that a cosmetic formula really works? Explore the role of stability testing, instrumental measurements, in vitro and clinical studies, sensory panels and consumer testing in evaluating cosmetic product efficacy.

How does a cosmetic active ingredient reach the right layer of the skin? Explore the role of the stratum corneum, molecular properties, formulation design, emulsifiers, emollients and advanced delivery systems in cosmetic skin delivery.

Microemulsions, nanoemulsions and conventional emulsions may all combine oil and water, but their structures, stability and formulation requirements are very different. Learn how these three emulsion systems compare and how formulators decide which technology is right for a cosmetic product.

What is HLB in cosmetic formulation? Learn how HLB values help formulators select emulsifiers and develop stable oil-in-water and water-in-oil cosmetic emulsions.

Discover why cosmetic products change over time and how stability and compatibility testing help ensure that a formula remains safe, effective, stable and compatible with its packaging throughout its intended shelf life.

PDRN has rapidly become one of the most talked-about ingredients in modern skincare. But what exactly is PDRN, how does it work, and how much of the science behind injectable treatments can actually be applied to topical cosmetic products?

Cleansers are designed to do something that sounds simple: remove dirt, excess oil, makeup and other substances from the skin. But there is a trade-off.

Sunscreen is one of the most familiar skincare products, yet the science behind it is surprisingly complex. One of the most common questions is whether mineral sunscreen or chemical sunscreen is better. The answer is not quite that simple. Both types can protect the skin from ultraviolet radiation, but they use different types of UV filters and behave differently within a cosmetic formulation.
