The acids of the ‘anti-aging’, those that irritate the skin most – Pharmaceutical Post – All Dermo

In Beauty

Cosmetics are products widely used that do not cause intolerance regularly but sometimes their use may pose a problem for the patient. According informs CF Leopoldo Borrego, a member of the Spanish Group of Cosmetic Dermatology and Therapeutics of the Spanish Academy of Dermatology and Venereology and professor at the University of Las Palmas de Gran Canaria, “the frequency of reactions cosmetics is underestimated, since most part of the population that has a problem with cosmetic changes to an equivalent cosmetic and only see when the problem becomes chronic. “

According to their data, “1.2 percent of general dermatology consultations are caused by intolerance to cosmetics and 0.76 percent are allergic to any substance in cosmetics”.

The most irritating

These negative reactions to cosmetics may be produced by the active substances as excipients therefore . In fact, according Borrego, “a cosmetic tolerance must be evaluated with the full product and not by parts”. Among the active ingredients that produce more irritative reactions “are substances, especially acids, employed to prevent skin aging” reports. Within allergic reactions “are especially important fragrances , ” he adds. As preservatives and skin reaction, the expert explains that “more causing allergic contact dermatitis are isothiazolinone derivatives”.

According to Borrego, these substances are in many cases necessary in cosmetics, so its final disposal is almost impossible . To maintain the stability of a cosmetic is essential, for example, the use of preservatives. “If not we use, the products would not be stable for a prolonged period of time , ” he explains. “Realistically, all marketed cosmetic use some preservative.

Controversy exists with the use of parabens, however, the currently permitted conditions do not appear to be more insecure than other preservatives “he says. In fact, he says, “Many times, when replacing a preservative consumer goods on the other, there are problems with the second that did not appear before because it was used less.”


In the case of fragrances, “they are used not only in cosmetics, but also in many household products.” As detailed, “the pleasant sensation we feel with a cosmetic is mainly based on their employment.” All fragrances ” may cause contact dermatitis , irritative -for both one acumulativo- effect, such that a person allergic to make it” notes. In addition, we must add that some fragrances, “also can cause reactions in relation to sun exposure, so as a rule it is important to avoid using and then exposing to light”.

As noted by the expert, a cosmetic intolerance can take many forms. “The most common are irritant contact dermatitis followed by allergic contact dermatitis, although we must not forget others like rosacea, seborrheic dermatitis or acne, problems that may occur with a worsening of the skin condition by using cosmetics inadequate “.


To prevent its occurrence, it is important, among other things, learn to understand the labeling of a cosmetic , which is not always easy. “Everyone should follow a standardized labeling as recommended by the European Agency” she reports. In them you can see what content includes, but is difficult to recognize them , considering that “for the purpose of industrial patent, if not from a concentration, it is not mandatory to declare all fragrances”.

For the expert, that are sold in pharmacies “does not imply greater security because the safer cosmetics are those in which the manufacturer offers more guarantees so it will depend on the provider you choose the pharmacist, not the fact itself they are sold in this health facility. ”

For Borrego, the pharmacist “is responsible for the quality of products that dispenses” and, as a health professional, “shall notify the Spanish Network Cosmetovigilance any possible adverse reaction that may present users with the use of a cosmetic product” .

5 Key to choose a cosmetic points.

1. The cost of a cosmetic unrelated to their effectiveness.
2. The impossible is impossible. Example: A cream can not refute sagging, which is a problem of deeper tissues (fat and muscle), not achievable by a cream.
3. Any treatment requires continuous use.
4. There is a remedy for everyone. Cosmetics should be tailored to the personal characteristics of each person.
5. very tech names or appeal to latest research “that sound” (stem cells, gene activation …) have, in many cases, human no scientific credibility. However, there are chemicals (molecules) which have demonstrated efficacy proven by rigorous studies. Examples, without to be an exhaustive: vitamin C and E, hydroxyacids, coenzyme Q10, kinetin, retinoids, certain peptides … An intelligent choice would be to select products with these active cosmetic companies controlled.
