Acne Explained

Acne vulgaris, or acne, is a skin condition that has multiple causes. This multifactorial property of acne makes it challenging for both the dermatologist and the patient to overcome it. Acne is characterized by formation of skin lesions that include pimples, comedones, papules, pustules, and cystic nodules. These lesions occur in areas rich in sweat and oily glands such as the face and chest. Factors contributing to the development are several. Some of the understood factors include excessive sebum production from the sebaceous glands, colonisation of bacteria (especially Propionibacterium acnes) and inflammation. Acne has profound psychological effects as well, as it impacts an individual’s self-esteem and quality of life. 

Prevalence of Acne in the UK

Acne is a prevalent skin condition affecting substantial portion of the UK population across various age groups. It remains one of the most common dermatological concerns in the UK.  According to a study published in the British Journal of Dermatology, approximately 80% of adolescents and young adults are affected by acne. 

What are Hydrocolloid Patches?

Hydrocolloid patches are adhesive dressings that were initially designed for covering the wound and its crucial role in promoting rapid healing. Application of hydrocolloid patches has gained popularity in the treatment of acne as they absorb excess sebaceous secretions, reduce inflammation, cover the inflamed zone from superimposed bacterial infections and promote wound healing.

Sizes and Shapes

Hydrocolloid patches are available in a variety of sizes and shapes to accommodate various kinds of acne lesions and wounds. Based on size difference, some patches are small while others are large. Small patches can be used to treat isolated pimples. Larger patches are fit for larger areas of the body such as diffuse acne on the face, chest and back, or it can also be used to cover larger wounds. Certain patches may also have a tapered edges while some others have additional ingredients such as tea tree oil or salicylic acid for enhanced efficacy.

Composition and Function

Hydrocolloid patches are moisture-retaining coverings that are composed of gelatin and carboxymethylcellulose. It forms a gel-like substance upon contact with skin and establish a water-resistant zone to prevent bacterial infections. This gel also helps in creating a moist environment on contact with the skin that proves conducive to healing while simultaneously absorbing excess sebum and impurities from the pimple.

Mechanism of Action

The unique mechanism of action of hydrocolloid patches makes it a definite choice for effective treatment of pimples. Upon application to a pimple, the hydrocolloid patch adheres itself to the skin and create a sealed environment. This occlusive environment helps in rapid healing as the contents of the patch are directed at the inflamed site only. The seal around the pimple prevents water or other impurities to reach into the healing zone. Hydrocolloid patch enhances the delivery of adequate moisture to the applied area and mediates wound healing.

Interestingly, along with providing moisture, these patches also absorb the excessive oily secretions and debris from the pimple to create a clean environment. This characteristic absorbent property of hydrocolloid material is what makes it a standout option for pimples. It helps in reducing inflammation and promote rapid resolution of the pimple by removing both bacteria and debris from the pimple.

Targeted Therapy

One of the many advantages of hydrocolloid patches is their ability to provide targeted therapy to individual pimples. Clindamycin is a popular medication used for treating pimples. This medication is supposed to be applied to the pimple and its surroundings or the entire face. It does not create a water-resistant barrier and can be easily wiped away unknowingly. Whereas hydrocolloid patches provide continuous treatment to its underlying pimple.  It delivers concentrated healing medication on top of the pimple while gently absorbing the debris within the pimple. It solely focuses on the pimple by working to soften it and minimize its risk of rupture or bacterial invasion.

Use and Convenience

One of the many benefits of hydrocolloid patches is their ease of use. Traditional acne treatments required great care and daily application of medications that may or may not work for the skin. Hydrocolloid patches on the other hand are easy and quick to apply directly on the pimple. The patch stays adherent to the skin throughout the day providing continuous treatment to the pimple, without interfering with daily activities. Once covered with a patch, its safe to apply makeup to the surrounding skin as well since hydrocolloid patch creates a seal around the pimple. Moreover, discreet appearance of hydrocolloid pimples makes it suitable for use in public settings as well without drawing much attention to it.

Proof of Performance

Several studies and research have time and again investigated the performance and effectiveness of hydrocolloid patches and its use in acne treatment. One such popular study was conducted in a randomised controlled clinical trial by Tan et al. This study confirmed that participants who used hydrocolloid patches for their acne experienced significantly rapid healing and resolution of pimples in comparison to those who did not use these patches.

Likewise, a study article published in the Journal of Dermatological Treatment in 2018 confirmed that hydrocolloid patches were effective in reducing the zone of inflammation of pimples. These patches were proven efficient in rapid reduction of the size, redness, and severity of acne lesions.   

Skin Suitability

Increased skin sensitivity is also one of the factors leading to increased acne. Sensitive skin experience frequent breakouts and delayed healing. Excessive sebum production in such skin then causes further damage as it creates a friendly environment for bacterial colonisation.

Hydrocolloid patches are generally well-tolerated by normal to dry to acne-prone skin. It has hypoallergenic properties that reduces the risk of irritation or allergies. Thus, these patches are safe for use by almost everyone with whichever skin type they may have. However, Welzo still recommends you take a patch test before going for routine use of hydrocolloid patches. Patch tests will help rule out known allergies or skin sensitivities to adhesive materials.

How long should I wear a hydrocolloid patch for pimple?

At least a 6 to 8 hours time is the recommended duration to wear a hydrocolloid patch for pimple. During this time, patch absorbs excess oil and pus from the pimple to promote rapid healing.
