Rejuvenating Treatments and Ozonated Products: What Are the Risks to the Skin?

Redness, tightness, a burning sensation, flaking… A skincare product designed to improve the skin’s appearance can sometimes have exactly the opposite effect if it is chosen poorly, is too concentrated, or is used excessively.

However, this does not mean that anti-aging treatments or ozone-based products are dangerous. Their tolerability depends primarily on their formulation, the concentration of active ingredients, the frequency of use, and the skin’s initial condition.

This distinction is particularly important for ozonated products. Gaseous ozone is a powerful oxidizing agent that is harmful if inhaled, but ozonated oil is not gaseous ozone applied directly to the skin. It results from the controlled reaction of ozone with the fatty acids in an oil, which forms, among other things, ozonides, peroxides, and other oxygen-containing compounds.

A systematic review published in 2022 also offers some reassurance: among 9 studies involving 2,628 participants, no significant dermatological risks were identified with the topical use of ozonated oils or waters. However, a few mild and isolated reactions were reported, including a burning sensation, itching, or erythema.

The main risks associated with anti-aging treatments and ozone-based products therefore primarily include irritation, sensitivity reactions, inappropriate combinations of active ingredients, and use that does not take the skin’s needs into account.

Skin irritation: the most common risk associated with active skincare products

When it comes to skincare, “stronger” doesn’t necessarily mean “more effective.” Many promising active ingredients can become irritating when used too frequently, at an inappropriate concentration, or in combination with other ingredients that also have a strong effect on the skin.

The first signs are usually easy to recognize: redness, persistent tingling, tightness, dryness, or flaking. They often indicate a temporary disruption of the skin barrier rather than a beneficial reaction to the product.

This is an important point, because irritation is not proof that a skincare product “works.” On the contrary, damaged skin can become more reactive, lose more moisture, and tolerate other products in your routine less well.

The risk increases when several exfoliating, keratolytic, or highly concentrated active ingredients are introduced at the same time. A rejuvenating skincare routine should therefore be built up gradually, allowing the skin time to adapt before adding a new active ingredient.

Some active ingredients require special caution due to their potential to cause irritation. This is particularly true of benzoyl peroxide, which is used to treat blemishes because of its effect on Cutibacterium acnes. While effective, it can nevertheless cause dryness, redness, flaking, or a burning sensation in some skin types.

This balance between effectiveness and skin tolerance is important in adults, when skin imperfections and signs of aging coexist: excessively weakening the skin barrier can increase discomfort and make the skin less tolerant of other skincare products.

Perfect Selfy Gab’s LifeSpan+, which combines BOP10 (benzoyl peroxide) and sulfur, is a perfect example of this type of targeted treatment that should be considered with the skin's sensitivity in mind.

Are ozonated products harmful to the skin?

This is probably the main question raised by this class of treatments, given the highly oxidizing nature of ozone in its gaseous form.

However, the available data on topically applied ozonated oils and water are generally reassuring. The 2022 systematic review specifically focused on their dermatological safety identified no significant short-term skin risks in the nine studies included. In a trial involving 2 ,165 people using ozonated sunflower oil, only 6 participants—about 0.3%—reported mild adverse effects such as burning, itching, or redness.

This does not mean that a reaction is impossible. Cases of irritant or allergic contact dermatitis associated with preparations containing ozonated oil have also been reported in the literature.

Concentration and formulation are important. In particular, an experimental study on medical ozonated oils observed mild irritation on damaged skin at high concentrations, while the lower concentrations tested did not cause this reaction.

In other words, the main concern is not “ozone” on its own, but rather the product’s formulation, its ozone content, the area of application, and the condition of the skin.

That is why a product specifically formulated for topical application, such asLifeSpan+1,200 IP Ozonated Oil , should be used according to its instructions rather than as an ordinary vegetable oil.

Be careful not to confuse ozonated oil with gaseous ozone

Confusion is common and can lead to erroneous conclusions about the dangers of ozone-treated products.

Breathing ingaseous ozone at high concentrations can irritate the respiratory tract and impair lung function. These risks are well-documented and have nothing to do with the use of an oil that has first undergone a controlled ozonation process.

In ozonated oil, the ozone has reacted with the double bonds in the fatty acids. It is the compounds resulting from this reaction that give the product its distinctive characteristics.

This distinction is essential when assessing the safety of ozonated products for the skin: data on respiratory exposure to gaseous ozone cannot be directly applied to the topical application of an ozonated oil.

Sensitive Skin: When Should You Be Especially Careful?

Not all skin types have the same ability to tolerate active skincare products. Anyone with a compromised skin barrier, significant redness, or a known sensitivity to certain ingredients should exercise particular caution when introducing a new product.

An unusual reaction should not be confused with a normal adjustment period. A mild, temporary tingling sensation may occur with certain active ingredients, but persistent burning, swelling, severe itching, or worsening redness are reasons to stop using the product in question.

It may be a good idea to test the product on a small area before using it for the first time, especially for people who have previously experienced reactions to cosmetics.

The area of application must also be taken into account. The skin around the eyes and on the lips is much thinner and more sensitive than that on many other parts of the face or body. Therefore, a product should not be applied to these areas simply because it is intended for use on the skin.

The main pitfall: including too many exercises in a single workout routine

Cosmetic retinoids, exfoliating acids, benzoyl peroxide, vitamin C acid, chemical peels… Taken individually, various active ingredients can be beneficial. But piling them on haphazardly can turn a sophisticated skincare routine into a source of irritation.

The problem rarely stems from a “toxic” interaction between two cosmetic products. More often than not, it is a cumulative irritant effect: several products simultaneously put a strain on the skin barrier, to the point where it exceeds what the skin can tolerate.

The symptoms are quite characteristic: skin that feels hot upon contact with products that are usually well tolerated, persistent redness, flaking, and a sensation of extremely dry skin or discomfort after cleansing.

The best strategy, then, is not so much to add another “repairing” product as it is to temporarily simplify your routine and then gradually reintroduce the active ingredients once your skin has returned to its normal condition.

That is also why it is better to focus on the skin’s needs rather than trying to combine all the active ingredients associated with skin rejuvenation.

Irritation or Allergy: How Can You Tell the Difference?

A reaction to a skincare product is not necessarily an allergy. In most cases, redness or discomfort caused by active ingredients in cosmetics is actually a form of irritant contact dermatitis: the skin reacts directly to a substance or exposure that it does not tolerate well.

Contact allergy is based on a different mechanism. It involves the immune system and generally requires prior sensitization to a substance. This is why it can develop after repeated use of a product that had previously been well tolerated.

The symptoms may nevertheless be similar: redness, itching, patches, or sometimes small blisters. The location can provide a clue: irritation is often limited to the areas directly exposed, whereas an allergic reaction may spread beyond the area of application.

This distinction is important because a confirmed allergy to an ingredient means that the ingredient must be identified and avoided, even when it is present in other products.

What signs should really raise a red flag?

Not all side effects are equally serious. Mild, temporary discomfort should not be equated with a reaction that persists, intensifies, or spreads.

The progression of a symptom is just as important as its nature. A reaction that worsens over the course of several hours or extends well beyond the area where the treatment was applied warrants more attention than very mild discomfort that disappears quickly.

Does the quality of ozonated products affect their safety?

Not all ozonated oils have exactly the same characteristics. Their composition depends on several factors: the type of vegetable oil used, the amount of ozone exposed to the fatty acids, the duration of the process, and storage conditions.

Ozonation triggers a series of chemical reactions that produce various oxygen-containing compounds. Their presence and concentration can be assessed using parameters such as the peroxide value, which is used to characterize the degree of ozonation in an oil.

This standardization is important because it ensures a product with known and reproducible characteristics. Research on ozonated oils also highlights the importance of their physicochemical characterization and stability—two essential factors when they are intended for topical application.

Therefore, the risk cannot be assessed based solely on the term “ozonated oil.” The product must be considered as a whole, and preference should be given to formulations that are specifically designed and tested for their intended use.

This is also what distinguishes an ozone-based product formulated for the skin from the uncontrolled use of ozone, where the concentration and characteristics are not regulated.

Rejuvenating Treatments and Ozonated Products: Overall Limited Risks

Above all, the available data help put potential dangers into their proper context.

For topically applied ozonated products, the results are generally reassuring: as mentioned earlier, the systematic review involving 2,628 participants did not identify any significant short-term dermatological risks. The reported adverse effects were infrequent and generally mild.

When it comes to other anti-aging or blemish-treating skincare products, caution depends more on the active ingredients in the formula. Some have a greater potential to cause irritation than others, particularly when they have an exfoliating or keratolytic effect or accelerate skin renewal.

It would therefore be an overstatement to consider rejuvenating treatments and ozone-based products as dangerous in and of themselves. The risk depends more on the formulation, skin condition, and individual tolerance. Conversely, presenting a treatment as completely risk-free simply because it is cosmetic or of natural origin would be just as inaccurate.

It is this approach that allows you to use LifeSpan+ Rejuvenating Caresolutions and ozonated products while understanding both their benefits and the key precautions to keep in mind.
