Acne can be persistent and difficult to manage, especially when it leads to scarring, inflammation, and deep breakouts. Medium to deep chemical peels offer an advanced treatment option that targets severe acne, clogged pores, and post-inflammatory hyperpigmentation. These peels penetrate deeper into the skin layers, effectively removing damaged skin cells, regulating oil production, and stimulating skin renewal for a clearer, smoother complexion. Medium to deep peels use stronger exfoliating agents such as trichloroacetic acid (TCA), phenol, or high-strength salicylic acid to reach the mid to lower dermis, making them effective for stubborn acne, deep scars, and long-term skin rejuvenation.

A skin biopsy is the definitive diagnostic tool in dermatology — it provides histopathological evidence that clinical and dermoscopic examination alone cannot always deliver. At Claire Derma, we perform biopsies when a skin lesion's appearance raises diagnostic uncertainty, when a rash fails to respond to standard treatment, or when monitoring detects changes in a previously stable mole.

These peels work by deeply penetrating the skin to:

Deep Exfoliation – Exfoliate dead skin layers and remove acne-causing debris.

Bacteria & Inflammation Control – Destroy acne-causing bacteria, reducing inflammation.

Pore Unclogging & Oil Regulation – Unclog pores and regulate oil production, preventing future breakouts.

Collagen Boost for Scar Reduction – Stimulate collagen production, helping to heal acne scars.

Clinical Indication Assessment – Our team evaluates each lesion against established biopsy criteria — changing moles, non-healing wounds, unexplained rashes persisting beyond six weeks, and suspected autoimmune skin conditions are all strong indications.

Biopsy Type Selection – Punch, shave, incisional, and excisional biopsies serve different purposes. Our dermatologist selects the technique that will provide the pathologist with adequate tissue depth and architecture for the suspected diagnosis, avoiding.

Site Selection for Rashes – When biopsying an inflammatory rash, the sample must come from an active, established lesion rather than a very early or resolving one.

Determining whether a biopsy is indicated — and selecting the correct biopsy type — is a clinical decision that depends on the suspected diagnosis. At Claire Derma, our dermatologists consider the lesion's size, depth, anatomical location, and the differential diagnoses being considered.

Deep Skin Cleansing – Intense exfoliation, clearing out deep-rooted impurities.

Cystic Acne Reduction – Reduction in cystic and nodular acne, decreasing painful breakouts.

Sebum & Oil Control – Oil regulation, balancing sebum production to prevent acne recurrence.

Skin Smoothing & Scar Healing – Smoother skin texture, reducing roughness and acne scars.

Punch Biopsy – A disposable circular blade is pressed into the skin with a gentle twisting motion, sampling all skin layers down to the subcutaneous fat.

Shave Biopsy – A thin disc of tissue is sliced from the skin surface using a DermaBlade or scalpel blade held at a tangential angle.

Excisional Biopsy – The entire lesion is removed with a two-millimetre margin of clinically normal skin in an elliptical shape. This technique preserves the lesion's complete architecture for histological assessment, including measurement of.

Biopsy technique at Claire Derma is precise and tailored to the diagnostic question. Punch biopsies use a circular blade — typically three to six millimetres — that cuts through the epidermis and dermis to the subcutaneous fat in a single motion. The cylindrical core is lifted with forceps and the wound is closed with one or two sutures.

Clears Severe Acne – Effective for cystic, hormonal, and treatment-resistant acne.

Prevents Future Breakouts – Regulates sebum and bacteria growth, preventing future breakouts.

Reduces Acne Scars – Stimulates collagen production, helping to heal acne scars.

Benefit – Histopathological confirmation removes the guesswork. Conditions that look identical clinically — basal cell carcinoma versus a benign trichoepithelioma, or psoriasis versus fungal infection — are definitively separated under the microscope.

Benefit – Early detection of skin cancer through biopsy allows treatment at the most curable stage. A melanoma biopsied while still thin is treated with simple excision and carries an excellent prognosis.

Benefit – For chronic skin conditions, biopsy confirmation justifies the use of targeted therapies — immunosuppressants, biologics, or phototherapy — that require a definitive diagnosis before initiation.

The diagnostic value of a properly performed skin biopsy cannot be replicated by any non-invasive method currently available. While dermoscopy, confocal microscopy, and AI-assisted imaging tools have improved clinical accuracy, they provide pattern-based probability rather than tissue-level certainty. A biopsy examined by a dermatopathologist reveals the cellular composition, architectural organisation, and depth of involvement that define the diagnosis.

This treatment is ideal for individuals who:

Struggle with moderate to severe acne or deep acne scars.

Experience frequent cystic or nodular breakouts.

Biopsy site care at Claire Derma is designed to be simple and easy to follow. Punch and excisional biopsy sites are closed with sutures and covered with a small adhesive dressing. Keep the area dry for the first 24 hours, then clean gently with water and reapply a thin layer of petroleum jelly with a fresh dressing daily. Avoid submerging the wound in baths, pools, or hot tubs until sutures are removed.
