Consistency describes the behavior of the cosmetic when scooped, spread and left on the skin. It helps distinguish a light gel from a cream, serum or thick balm.
More than thick or fluid
Two cosmetics that look similar in the packaging may behave differently under finger pressure. One melts easily, the other keeps its shape longer or provides greater glide. This is determined by phase proportions, thickeners, emulsifiers and other ingredients of the formulation. A higher density should not be equated with a higher content of valuable substances. A small amount of the appropriate thickener can significantly change the appearance without changing the purpose of the cosmetic.
Choosing a texture for the application area
Comfortable consistency depends on skin area, method of application and desired finish. On a larger surface, ease of spreading is important, and in the case of precise application, keeping the preparation in the selected place. Massage gel and serum may have different tasks despite being similar in transparency. The possibility of use on mucous membranes or compatibility with condoms should not be inferred solely from the fact that the product looks like a lubricant.
Consistency change
Temperature and storage conditions may affect the feel of the product. Noticeable separation, unusual odor or unexpected color change require caution and checking the instructions. Do not add water to the thickening cosmetic or mix it with another preparation in the packaging: this changes the formulation and its protection conditions. When comparing consistency, take into account quantity and skin temperature rather than judging the product solely by the side of the bottle. If in doubt, ask the manufacturer about a given batch.
