What Is Acne?
Acne vulgaris is a multifactorial inflammatory condition that affects the pilosebaceous units of the skin, the structures that house each hair follicle and its associated sebaceous gland. It is one of the most prevalent skin conditions worldwide, affecting people across a wide range of ages, skin tones, and backgrounds. While it is often associated with adolescence, adult-onset and persistent adult acne are increasingly common, particularly in women.
The condition ranges considerably in severity and presentation. At its mildest, it may involve scattered blackheads and whiteheads with minimal inflammation. At its most severe, it can involve deep, painful nodules and cysts that carry a significant risk of permanent scarring. Most presentations fall somewhere between these extremes, with a mix of comedonal and inflammatory lesions that fluctuate in response to hormonal changes, stress, skincare habits, and other factors.
Acne is not simply a cosmetic nuisance. Its impact on confidence, self-perception, and quality of life is well documented, and it is a condition that deserves a thorough, evidence-grounded approach rather than dismissal. At Regener8 Aesthetics in Selly Oak, Birmingham, the aim is to provide honest assessment and to identify which elements of aesthetic care may support your skin alongside any medical management you are receiving.
Acne arises from four primary mechanisms acting together: excess sebum production by the sebaceous gland, abnormal follicular keratinisation that causes the pore to become blocked, colonisation by Cutibacterium acnes (formerly Propionibacterium acnes), and an inflammatory immune response within the follicle. Treatments that target one or more of these mechanisms can help to reduce lesion frequency and severity.
Symptoms
Acne presents across a spectrum, and many people experience more than one lesion type simultaneously. Common presentations include:
- Open comedones (blackheads): follicles blocked with sebum and dead skin cells that have oxidised at the surface, producing a dark appearance
- Closed comedones (whiteheads): blocked follicles covered by a layer of skin, appearing as small, firm bumps without visible openings
- Papules: small, raised, red inflammatory lesions without a visible pus-filled head
- Pustules: inflamed lesions with a visible collection of pus at the surface, surrounded by redness
- Nodules: larger, deeper, firmer lesions without a pus-filled head that can be tender to the touch and slow to resolve
- Cysts: deep, fluid-filled lesions that are often painful, prone to rupture beneath the skin, and carry the highest risk of scarring
- Post-inflammatory marks: flat areas of redness or discolouration (post-inflammatory hyperpigmentation) that remain after an active lesion has resolved
- Scarring: permanent textural changes to the skin following significant or repeated inflammatory damage to the dermis
Acne most commonly affects the face, but the chest, back, shoulders, and neck are frequently involved, particularly in more severe presentations.
Causes and Triggers
The four mechanisms that drive acne, excess sebum, follicular hyperkeratinisation, bacterial colonisation, and inflammation, do not act in isolation. They are influenced by a range of internal and external factors that vary considerably from person to person.
Androgens, particularly testosterone and its derivatives, are central to sebum production. During puberty, rising androgen levels stimulate the sebaceous glands to produce more sebum, which is why acne is so prevalent in adolescence. In adults, hormonal fluctuations related to the menstrual cycle, pregnancy, polycystic ovary syndrome (PCOS), and changes to hormonal contraception can all trigger or worsen acne. This explains why adult acne disproportionately affects women and why breakouts often follow a cyclical pattern.
Dietary factors have received growing attention in the research literature. High glycaemic load diets, characterised by frequent consumption of refined carbohydrates and sugary foods, are associated with increased insulin and IGF-1 levels, which in turn stimulate sebum production and follicular keratinisation. The role of dairy is debated, with some studies suggesting a modest association, particularly with skimmed milk. Individual responses to dietary factors vary, and diet is best understood as a contributing variable rather than a universal or primary cause.
Psychological stress influences acne through the hypothalamic-pituitary-adrenal axis. Elevated cortisol can increase sebum production and promote an inflammatory skin environment. Many people notice a clear relationship between periods of high stress and worsening breakouts, and addressing stress as part of a broader skin management approach is relevant.
Certain skincare and cosmetic products can block follicles and worsen congestion, a phenomenon known as cosmetic acne or acne cosmetica. Heavy, occlusive moisturisers, oil-based foundations, and comedogenic sunscreens are common culprits. Reviewing the comedogenicity of products in use is a worthwhile element of any acne consultation. Some medications are also associated with acne as a side effect, including certain corticosteroids, lithium, and some epilepsy medications.
A Note on the "Poor Hygiene" Misconception
Acne is not caused by poor hygiene. This is a persistent and unhelpful myth that can lead people to over-cleanse their skin with harsh products, disrupting the skin barrier, altering the natural skin microbiome, and ultimately compounding the problem. Thorough but gentle cleansing is appropriate; aggressive scrubbing, frequent washing with stripping cleansers, and abrasive physical exfoliants are not. The cause of acne is biological, not a reflection of cleanliness.
Androgens, follicular biology, bacterial colonisation, and inflammation form the core of acne pathophysiology. Hormonal fluctuations, high glycaemic load diets, stress, comedogenic products, and certain medications can all act as triggers or amplifiers. Identifying which factors are most relevant to an individual allows a more targeted approach to management.
Who Is Affected?
Acne affects people across all ages, skin tones, and backgrounds. Up to 85% of adolescents experience some degree of acne, making it nearly universal during the teenage years. For many, it resolves or significantly improves in early adulthood, but for a substantial proportion it persists or first develops in adulthood.
Adult acne is increasingly recognised, particularly in women aged 25 to 45. Research suggests that approximately 40 to 55% of adults in this age group experience facial acne, and the hormonal dimension is frequently relevant. Perimenopause, which brings fluctuating oestrogen and progesterone levels, can trigger or worsen acne in women who had clear skin for years beforehand.
Acne affects people of all skin tones, though the way it presents and the risk of associated complications can differ. Individuals with darker skin tones are more prone to post-inflammatory hyperpigmentation, where healed lesions leave lasting dark marks that can be as distressing as the acne itself. This is an important consideration when selecting treatments, as some interventions carry a higher risk of triggering or worsening pigmentation in certain skin types. At Regener8 Aesthetics, the assessment and treatment approach takes skin tone fully into account.
A family history of acne increases an individual's likelihood of developing the condition, reflecting the genetic component of sebaceous gland activity and follicular biology. However, acne does not require a family history to occur, and its severity does not always follow a predictable genetic pattern.
Diagnosis and Assessment
Acne is primarily diagnosed through clinical examination. A practitioner will assess the types of lesions present, their distribution, their severity, and any existing scarring or post-inflammatory marks. A thorough history covers the duration and pattern of the condition, any treatments already tried and their outcomes, relevant hormonal history in women, dietary habits, skincare products in use, and any medications that may be contributing.
Grading acne by severity is an important step in determining the most appropriate management pathway. Mild acne, characterised predominantly by comedones and a small number of inflammatory lesions, may be well suited to aesthetic treatment support alongside optimised skincare. Moderate acne, with a higher number of papules and pustules, typically benefits from a combination of aesthetic treatments and medical management. Severe acne, involving nodules, cysts, or widespread inflammatory lesions, requires primary management by a GP or dermatologist; aesthetic treatments can support but not replace this.
In women where the history or pattern suggests a hormonal driver, a referral to a GP for hormonal assessment is appropriate. Blood tests for androgens, luteinising hormone, follicle-stimulating hormone, and markers of PCOS may be relevant. Where acne is suspected to be medication-induced, a review with the prescribing clinician is warranted.
At Regener8 Aesthetics in Birmingham, the initial £25 consultation provides time to assess your skin properly, discuss your history, and have a candid conversation about which aesthetic treatments may help and where the boundaries of aesthetic care lie. There is no pressure to book treatment on the day.
Evidence-Based Treatments
The management of acne typically involves a combination of approaches, and aesthetic treatments form one component of a broader strategy. The clinical severity of your acne shapes which treatments are appropriate and in what sequence.
Medical Management
Regener8 Aesthetics does not prescribe oral or topical antibiotics, combined oral contraceptives for acne, or isotretinoin. These are medical treatments that must be initiated and supervised by a GP or dermatologist. Where the assessment suggests moderate to severe acne or a clear hormonal component, the most beneficial step will often be to engage medical management first, with aesthetic treatments providing additional support once the skin is more stable. We will communicate this clearly and can facilitate appropriate referral.
Chemical Peels
Superficial and medium-depth chemical peels are among the most evidence-supported aesthetic interventions for acne-prone skin. Salicylic acid peels, being oil-soluble, penetrate into the sebaceous follicle and are particularly effective at loosening comedonal plugs, reducing sebum accumulation, and exerting an antimicrobial effect against Cutibacterium acnes. Glycolic and lactic acid peels improve epidermal cell turnover, reducing the likelihood of follicular occlusion, and can also help to fade post-inflammatory marks.
At Regener8 Aesthetics, chemical peels are carried out after a full skin assessment. The choice of acid, concentration, and number of layers applied is guided by your skin type, Fitzpatrick scale classification, the nature of your acne, and your skin's previous response to any exfoliating treatments. Patch testing is carried out where appropriate, particularly for those with sensitive or reactive skin. A series of peels spaced two to four weeks apart generally produces better outcomes than single sessions.
Microneedling
Microneedling creates controlled micro-channels in the skin using fine needles, stimulating the skin's repair mechanisms and promoting collagen production. For active acne, it can reduce sebaceous gland activity and improve the overall skin environment. It is also useful in the early stages of acne-related scarring, where it encourages dermal remodelling before scars become fully established. Microneedling is not appropriate during active severe flares with widespread pustular or cystic lesions, as there is a risk of spreading bacteria and worsening inflammation. Timing is assessed carefully at consultation.
PRP, Platelet-Rich Plasma
PRP therapy, sometimes referred to as a vampire facial when combined with microneedling, involves concentrating the platelet-rich component of the patient's own blood and applying or injecting it to stimulate growth factors and reduce inflammation. For acne-prone skin, PRP may help to calm the inflammatory environment, support skin barrier repair, and improve overall skin quality. It is not a primary treatment for active acne but can complement other approaches, particularly where the focus is on skin quality and early scar prevention.
Profhilo and Jalupro
Injectable biostimulators such as Profhilo and Jalupro work by improving skin hydration, supporting the extracellular matrix, and enhancing overall skin quality. They are not primary treatments for acne and will not address the underlying mechanisms of sebum overproduction or follicular blockage. However, when acne has compromised the skin barrier or skin quality more broadly, they can support the restoration of a healthier skin environment as part of a longer-term plan.
When to Seek Referral
Nodular or cystic acne, acne that has not responded to multiple treatment approaches, acne strongly suspected to be driven by PCOS or another hormonal condition, and acne in younger adolescents should be assessed by a GP in the first instance, with dermatology referral considered where appropriate. Regener8 Aesthetics will always be transparent when aesthetic care is not the primary need and will support you in accessing the right level of care.
