Salicylic Acid Side Effects and How to Avoid Them?

Salicylic Acid is an organic acid that is extracted from the bark of willow trees. It is the most popular and beloved compound among skin therapist or dermatologists due to its unbeatable capability to penetrate through moisturized layers of the surface and then penetrate the follicles walls, disintegrate the sticky architectural sebum as well as opens up the dead skin cells to form microcomedones.

Unfortunately, it is an extremely potent oil-soluble chemical exfoliant and as such, it requires utmost care. In the quest for achieving perfect porcelain-like skin in the modern times, people often go overboard with this product.

As a result, driven by their need for quick effects, people apply strong formulas, skip the necessary hydration stage to rebuild their moisture barriers, and apply many aggressive acids at once in their daily routine. All of this results in epidermal irritation, erythema, impaired moisture barrier as well as salicylic burning sensations.

This comprehensive blog will help you to understand the negative consequences of BHAs in order to use the benefits of this acid without harming the skin.  

Key Takeaways:

• Flaking temporarily is expected, but if there is continuous peeling, excessive redness, or instant burning after using salicylic acid, indicates that you have a weak skin barrier or could be even allergic to salicylic acid.
• In order to totally prevent adverse reactions of salicylic acid, begin with small concentrations of 0.5%-1%, apply only twice weekly, and ensure that the skin is fully dry before application.
• You should remember not to stack your ingredients by applying products that consist of salicylic acid with other harsh acids like retinoids, as well as should only follow up with ingredients that will help in repairing your skin barriers like ceramides and hyaluronic acid.

How Salicylic Acid Interacts with Your Skin Dermal Layers?

It is therefore important for one to consider how salicylic acid affects the human body specifically from the reaction of skin cells to the acid. However, one major structural distinction between Alpha Hydroxy Acids (AHAs) such as glycolic acid, lactic acid, or mandelic acid and beta-hydroxy acids (BHAs) is their solubility characteristics.

In that regard, AHAs are entirely water-soluble molecules. AHAs have a mechanism of action that mainly affects the outermost part of the skin known as the stratum corneum.

On the other hand, Salicylic Acid is lipophilic, which means that it is fully soluble in fats. This particular characteristic enables the acid to penetrate through the lipid layer and enter into the deeper parts of the lining of the follicle as well as sebaceous glands.

It will then dissolve the clogged combinations of keratinized cells and sebum, forming comedones and acne.

Although this type of cleansing works exceptionally well for treating acne-prone skin, it will also strip away quite a bit of your skin's natural oils. The sebum is what helps to maintain your skin barrier and keep your skin moisturized, as well as protect your face from any irritants in the environment.

If you use a skin product that strips away oil too fast or your skin is inherently dry or fragile, the outer layer of your skin will dry out and become very susceptible to irritation.

How to Identify Salicylic Acid Side Effects?

In case you decide to add an effective chemical exfoliant to your skincare regimen, it is important to understand the difference between normal adaptation of the skin and a negative response.

1. Expected salicylic acid side effects 

In case of the introduction of a BHA into your skin care routine for the first time, there is going to be an adaptation phase where you will notice mild and temporary changes. These changes include:

• Mild Skin Purging: It helps in faster cells turn over and allows microcomedones that have been deep inside to come out much more quickly than would normally be expected. It may lead to a transient increase in small white bumps or pimples. The purge happens only in areas where one gets pimples and takes just a few weeks to resolve.
• Slight Temporary Dryness: It is common to feel some tightness or slight flaking around the nose or your mouth due to reduced oil on the skin’s surface.

2. Abnormal Side Effects

If you experience the above signs of the condition for more than two weeks, develop it in regions of your face that rarely get affected, and it causes physical discomfort, then you are definitely suffering from a real case of salicylic acid dermatitis. This suggests that either:

• Flaking and Peeling: Seeing large sections of your skin flaking off means that too much lipids are being stripped off by the acid, leaving your skin exposed.
• Erythema and Inflammation: Prolonged patches of reddened skin which resemble minor sunburn are caused by inflammation of the blood vessels in your dermis from over-exfoliating.
• Glass Skin Paradox: Although having soft skin is important, an overly tight and shiny look with very sensitive skin means that you have stripped your stratum corneum too much.

3. Acute Over-Processing

In case you feel an instantaneous salicylic burning effect that stays with you even after you have washed the cream off, then you should be aware that your skin is trying to tell you something.

Localized chemical burns are characterized by inflammation or pain in the form of red patches that eventually develop a dark-brown color or become crusty. This kind of reaction usually occurs when an at-home treatment procedure involves misapplication of a professional peel (15–30%) and lack of neutralization, or application of a 2% serum directly onto open wounds, pustules, and eczematous spots.

What Should You Do in Order to Avoid Side Effects?

Salicylic acid should not be discarded altogether simply because you have sensitive skin. There is no problem in adjusting application method, time and frequency so as to prevent any risk whatsoever.

1. Patch Test Application

Don’t use an untested chemical-based product all over your face when it is brand new. By doing a patch test, you will be able to determine any problems that may arise from using the product.

Method:

• Place 2 to 3 drops of your selected product on a discreet location on your skin that is clean. Examples of this could be the inside of your forearm or the back of your neck close to your earlobe.
• Keep the product running for 24 hours.
• Be sure to monitor for any symptoms of swelling, persistent itching, reddening or even blisters.
• In case your salicylic acid skin reaction is okay, you are free to apply the product on your face.

2. Practice the Low and Slow Method

In terms of active skincare products, less can be more than better. It is always quicker to develop an allergy when using a product of high concentration straight away.

• Start with Low Concentrations: In case of leave-on products used on a daily basis, the formulation should contain between 0.5% and 1% of salicylic acid before progressing to 2%.
• Limit Your Initial Frequency: You should use this treatment twice per week in the first two weeks. Once you realize that your skin barrier is comfortable without any flaking and redness, you can increase your usage gradually to twice a day, but if needed, you could apply daily.
• Choose Rinse-Off Formulations First: In case your skin is highly reactive by nature, it may be more appropriate for you to use a wash-off type of product such as a salicylic acid wash instead of a serum since this will allow the active ingredient to work on your pores.

3. Avoid the Danger of Ingredient Stacking

• Mixing too many strong active ingredients into one skin care regimen is often the most frequent reason why skin reacts badly. One does not need to fight for Salicylic acid with any other strong ingredient or product on the skin.
• Separate Your Actives: Do not use Salicylic acid along with Retinol, Glycolic Acid, Lactic Acid, or any high concentration of Pure Vitamin C.
• Create an Organized Schedule: Apply your Salicylic Acid in the evening, while your Vitamin C can be used in the morning. If you are applying retinoids in the evening or alternating nights, you would need to change this routine so that you apply your retinoid on Mondays, your salicylic acid on Tuesdays, and have a plain moisturizing regimen on Wednesdays.

4. Hydration and skin irritation

For prevention of dehydration and skin irritation, it is important to add back the moisture that chemical exfoliation strips off the skin. Make sure that you moisturize all the time.

• Keep Skin Dry Before Application: Remember to always use your salicylic acid products on fully dried skin. Putting acids on wet skin will enable the acids to enter your skin more deeply and faster, hence increasing the chances of burns.
• Follow with Barrier-Repairing Ingredients: Give your acne product 2 to 3 minutes to be fully absorbed into your skin, and then put on a liberal amount of soothing moisturizer. Moisturizers containing high amounts of Ceramides, Cholesterol, Glycerin, and Hyaluronic Acid would be highly recommended.
