Acne Management For Aesthetics Practitioners

Acne Management For Aesthetics Practitioners

Acne is a common skin concern that, as aesthetics practitioners, we see frequently. As such, “skin first” aesthetics specialist and senior clinical trainer, Dr Raquel Amado has provided this full run down to help you better understand acne management.

Acne Management For Aesthetics Practitioners

What is acne and how is it treated?

Acne is a common chronic inflammatory skin condition that involves the dysfunction of the pilosebaceous unit (hair follicles and oil glands). It is managed by reducing oil production, speeding up skin cell turnover, treating bacterial infection and reducing inflammation. This ultimately helps the goal to prevent scarring.

Elements that interrupt the physiological processes of acne include:

  • Antibiotics to reduce counts of Cutibacterium acnes bacteria.
  • Anti-inflammatory ingredients to calm red and inflamed skin.
  • Comedolytics to unplug blocked follicles.
  • Keratolytic agents to exfoliate the surface scaling.
  • Agents that affect keratinisation to help normalise skin cell maturation.
  • Hormonal therapy to reduce androgen activity like sebum production.

The three main types of acne management

Acne management usually involves a combination of approaches. The three main options are topical applications, oral medication and clinical skin treatments.

Acne management advice for aesthetics practitioners

Topical treatments

Retinoids encourage exfoliating of the skin, keeping pores unclogged and preventing comedones. 

Salicylic acid is a keratolytic. By softening keratin, it takes off the upper layer of skin. As well as unclogging pores, it breaks down whiteheads and blackheads. It also allows additional topical products to penetrate the skin better. 

Azelaic acid – as an antibacterial, keratolytic and comedolytic, it reduces Cutibacterium acnes and Staphylococcus epidermis on the skin. It also helps normalize the shedding of dead skin cells and decreases inflammation by scavenging free radicals. Azelaic acid also importantly improves post-inflammatory hyperpigmentation. 

Benzoyl peroxide reduces the number of bacteria on the surface of the skin without causing bacterial resistance. It also has an anti-inflammatory effect. As an oxidizing agent, it is keratolytic and comedolytic. It also has an anti-inflammatory action.

Topical antibiotics such as clindamycin or erythromycin, improve acne by stopping the growth of acne-causing bacteria. They also help reduce inflammation and are thought to decrease the amount of blocked pores.

Nicotinamide may improve acne through its anti-inflammatory action and by reducing sebum production.

Oral treatments

Oral antibiotics such as macrolides (eg. erythromycin) or tetracyclines (eg. doxycycline), are the most common antibiotics prescribed. They act by reducing bacterial colonisation and inflammation in the affected follicles, but they do not cure acne. Interestingly, they are less associated with bacterial resistance compared to topical antibiotic preparations. They can be used for short periods of time, up to 6 months. 

Oral contraceptive pills are a hormonal intervention that reduce androgen activity. This helps with the reduction of sebum production. Consequently, there is less follicle obstruction and the medium for bacterial growth is reduced. It is a more medium-term treatment and can take up to 6 months to see results. This treatment comes with associated side effects and should be considered with the patient’s GP.

Isotretinoin (dermatologists only) is a drug that can help to effectively suppress severe acne for as long as two years. It is the only therapy that impacts all of the major acne-causing factors. It results in a reduction of sebum production, reduces comedogenesis, lowers surface and ductal P. acnes and has anti-inflammatory properties. However, it has several severe side effects including depression and liver/kidney problems. It can cause birth defects, which means patients should not become pregnant while taking it. The treatment lasts between 4 to 6 months and it can cause severe dryness of the skin. Most skin actives and in-clinic skin treatments cannot be used with patients taking this potent medication.

Spironolactone (dermatologists only) can be used off-licence as it can also have hormonal effects by blocking the action of androgens.

Cosmetic Dermatology course chemical peel training

Clinical skin treatments

Chemical peels will promote exfoliation of the skin using ingredients such as salicylic acid, glycolic acid or retinoic acid. 

UV light therapy may help as it has an antimicrobial and an anti-inflammatory effect which promotes skin healing. 

Microneedling can be effective for acne scarring due to its induction of collagen production.

Know your limits

Managing acne can be challenging, so it’s important to know your limits, referring appropriately in severe or resistant cases. Due to the psychological impact this condition can have on an individual, the rewards of managing acne well can be profound, as long as realistic expectations are discussed. It takes time, patience and effort from the patient and practitioner alike!
