Cream For Allergic Reaction. Some components of the facial treatment products have irritating results on the skin. The specialists tell us what these active ingredients are and why they can be replaced with similar results.
Many women usually notice when changing cleaning emulsion or cream treatment, that their skin generates a kind of rejection of the product through redness, itching and tightness, among other reactions. Others, however, have always had a frail skin and have suffered from redness and poor tolerance to hygiene products, anti-acne or sunscreen. The difference between the two is that the latter is sensitive skin by nature, while the former is sensitized or suffers from allergy as a reaction to a particular allergen or active ingredient.
In both cases the ideal is to use creams with a minimum of ingredients, without parabens, fragrances, dyes or fatty bodies, all of which are susceptible to irritants.
Allergic reactions depend on the subject and not the product that is applied, what gives allergy to one person does not give to the other, the answers are individual.
What Unleashes These Reactions?
“Sensitive skin often appears in areas of aggressive climate where there is extreme dryness or wind, and in people who use many products at the same time,” says Dr. Patricia Dermer, biochemist. However, many women notice that over the years their skin becomes more sensitive and presents all kinds of adverse reactions. “We are exposed to a huge amount of stimuli of all kinds that produce effects on the skin and this accumulation can produce a sensitization that is an amplified response to a new stimulus.
It is important to note that the makeup products, dyes, spray for the environment, etc., and not only the creams, are also captured by the nerve terminals of the skin and produce irritative effects. The sensation of pleasant or unpleasant, rough, silky, cold, etc., are various sensations that are taken by the neurotransmitters of the skin and go to the brain that decodes them, and creates these responses, “adds Dermer.
Among the substances that make up cosmetics and often cause reactions in sensitive skin are acids, preservatives, perfumes and abrasives. The laboratories have tables with reports of adverse reactions.
“Creams with acids should be replaced by other products for sensitive skin, as effective as the previous ones, with specially designed formulas,” says Dermer. There are even perfumes that come from simple botanical extracts that can be added to the creams to make them more pleasant to the senses.
The misuse or misuse of a product can also be the source of serious discomfort in the skin. For example, use in the eye area a facial cream that is not ophthalmologically tested since it has been formulated to be placed over the eyebrow and from the bone of the cheekbone downwards. It can also happen that a menthol, acid or thermogenic product is used, not indicated for the eye area and irritating it.
“But good facial creams should be well tolerated even when used close to the eye,” says Dermer.
In addition to the aforementioned misuse, reactions can also trigger the high concentration of the product, the excessive exposure time, humidity (increases the contact ability of cosmetics with the skin), the association of different elements that act as vehicles, emulsifiers , preservatives, antioxidants and sunscreens. Together with perfumes and dyes they are a potential source of allergens, that is, they can produce an allergic reaction.
Most Common Reactions
There are five varieties of allergy. Cosmetics can lead to any of these occurring:
- Type I: Immediate hypersensitivity. The allergic reaction occurs immediately after a first contact with the product.
- Type II: After the initial treatment with the cosmetic, antibodies are generated against it, which, in the event of a new contact, will generate the symptoms.
- Type III: The antibodies already present stick to the component that generated the allergy and trigger a series of defense reactions to eliminate it.
- Type IV: Delayed hypersensitivity. It is the most frequent and occurs 48 hours after contact with the cosmetic that caused it.
- Type V: The body generates a cellular barrier against the component that caused the allergy to remove it from the body.
The symptoms of these allergies can be cutaneous manifestations -eccema, acute or chronic urticaria, residual pigmentation and lichenoid dermatosis-, and extracutaneous manifestations -rinitis, hay fever, allergic asthma, conjunctivitis, gastrointestinal alterations, angioedema and in some cases with allergic reactions. severe as anaphylactic shock.
In handling these cases, the first step is to suspend the use of the products that contain the allergen responsible for the condition permanently.
The medical treatments that are used against these pathologies is the prescription of anti-inflammatory drugs, antihistamines, corticosteroids, chemical or biological immunomodulators are the therapeutic weapons that the specialist currently has.
In less severe cases, sensitive skin is relieved by thermal water-based products, which have a calming and decongestant effect. The products with chamomile, calendula or rosemary are highly decongestant especially if they are used cold, freshly taken out of the refrigerator.
What Is A Hypoallergenic Product?
“Hypoallergenic products are those that, due to their formulation and controls, have a low probability of triggering an allergic reaction. There are lists of substances that should be avoided in the formulation of cosmetics, “says Mariana Boggione, pharmacist, who lists the characteristics that must have hypoallergenic creams:
- For products to be hypoallergenic, they must be tested on sensitive and / or allergic skin.
- Among the hundreds of thousands of available raw materials, only a very small proportion is selected.
- There are hypoallergenic perfumes, which are incorporated into products that are not potentially irritating
- In nail polishes the use of substances such as colofan, toluene and formaldehyde is avoided. In addition, tolerance tests are carried out on sensitive skin
- A expired cosmetic can also cause allergic reactions that is why the expiration date is placed on the packaging of the cosmetics.
What do you do when you want to use anti-aging creams? Many women think that they should give up treating wrinkles because the components can cause allergies. Fortunately, there are other alternatives.
“The acids that produce allergies in general are the chemical ones. Those of natural origin, such as glycolic acid (from sugar cane), citric acid (derived from citrus fruits), generally do not cause allergy problems. Most commercial brands use chemical acids, from retinoic acid, which is named Retinol as generic, without clarifying that it is very photosensitizing and irritative.
Actually, technically speaking and in the practical test, the best reaffirming and anti-aging are the alphahydrocycids (AHAs) with the glycolic at the top, “says Carlos Lizardi, cosmetic chemist.
“Today there are two new good anti-aging compounds, although without the strength and power of the previous ones. With a slower but more effective effect, these are the biopeptides and the new active ingredient from the Malus Domestica Swiss apples, which is a component that is combined with stem cells, “explains Lizardi.
How To Preserve Cosmetics
Cosmetics should be stored in dry, cool places. If the weather is very hot and humid they can be kept in the refrigerator. For example, liquid makeup.
- Keep the containers tightly closed since the contact with the air alters the product.
- Do not expose them to the sun.
- The brushes, sponges and accessories that are used to apply makeup should always be dry and clean so that no water or dirt enters the container.
- Wash your hands thoroughly before applying a treatment product on the skin.
- Use a measuring spatula to apply the creams so as not to contaminate them with your hands. Wash it after each application.
- Check the expiration date before buying and before use, if the box has been stored for a long time.
- Cleansing milks, moisturizing emulsions or treatment creams should not be kept open for more than a year. They should be discarded if the expiration date was passed even if they were closed.
Duration Of Cosmetics
According to a survey conducted in Britain by the Opinium Research pollster, 66% of women use their cosmetics even when they are expired. This is frequently cause of irritations and allergies. It is important to control the expiration date. Once opened, the cosmetics last:
- Eyelash mask, between four and six months. It is easily noticed if they are due to the consistency, the lumps and the deteriorated color of the product.
- Shadows for eyelids and blush in cream or mousse: 18 months.
- Compact powder, shadows and blush: they have a long life since they do not have a water base. But they must be handled in a hygienic way.
- Eyeliner: 18 months
- Lipstick: two to three years because it is made based on wax.
- Bases and concealer of dark circles: one year
- Perfume: up to three years, according to its quality. The gloss contains an aqueous base that becomes contaminated and lasts 18 months.
