The personalised guidance and home routine recommended after an in-clinic treatment. Considered aftercare supports comfort during recovery, helps protect results and reduces the likelihood of avoidable side effects.

A family of water-soluble exfoliating acids — including glycolic and lactic acid — that help loosen and lift dead surface cells. Used at appropriate strengths, AHAs may support a smoother texture and more even tone.

A structured, professional assessment with a qualified practitioner to discuss aesthetic concerns, goals, medical history and suitability for any considered treatment. Every plan at Aesthetics By Boss begins here.

The ability of the outer skin layer to retain moisture and resist environmental stress. A well-supported skin barrier looks calmer, feels more comfortable and tolerates active ingredients more predictably.

An oil-soluble exfoliating acid, most commonly salicylic acid, that can travel into pore openings. May help support clearer-looking skin in oilier or congestion-prone areas when used appropriately.

A label given to sunscreens that protect against both UVA (associated with photoageing) and UVB (associated with sunburn). In Brisbane's high-UV climate, a daily broad-spectrum SPF 30 or higher is strongly recommended.

Naturally occurring lipids that help hold skin cells together and support the moisture barrier. Topical ceramides are often used to help soothe and reinforce skin that feels dry, sensitised or compromised.

A structural protein produced in the dermis that gives skin much of its firmness and resilience. Collagen production gradually slows with age and is influenced by sun exposure, lifestyle and overall skin health.

Another term for skin microneedling, where controlled micro-channels in the skin support the body's natural repair response. Outcomes depend on individual skin and a tailored plan discussed at consultation.

A general term for skin that looks or feels blocked, with visible bumps, blackheads or uneven texture. A professional skin assessment helps identify likely contributors before recommending an approach.

A specific reason a treatment may not be appropriate for an individual, such as a medical condition, medication or recent procedure. Identifying contraindications is a core part of the consultation process.

Dehydrated skin lacks water and can affect any skin type, often appearing dull or tight. Dry skin lacks oil and is considered a skin type. The two can occur together and benefit from different supportive routines.

The middle layer of skin sitting beneath the epidermis. It contains collagen, elastin, blood vessels, nerves and structures that support strength, elasticity and sensation.

A two-step evening routine that uses an oil- or balm-based cleanser to lift sunscreen and makeup, followed by a gentle water-based cleanser. Useful for many lifestyles, though not essential for every skin.

The period after a treatment when visible side effects such as redness, swelling or sensitivity may be present. Expected downtime varies between individuals and treatments and is discussed before booking.

A protein in the dermis that allows skin to stretch and return to its original shape. Like collagen, elastin reduces with age and is significantly affected by chronic sun exposure.

The outermost skin layer, responsible for protection, hydration regulation and the visible appearance of the skin. The stratum corneum sits at its surface.

The process of removing surface skin cells, either mechanically or with acids and enzymes. Considered exfoliation, suited to the individual, can support smoother texture; over-exfoliation can compromise the barrier.

A detailed assessment of facial proportions, skin condition and individual goals. The consultation produces a personalised plan and clear information about any considered treatments, without pressure to proceed.

A consultation focused on understanding structural changes to the face over time, including how volume distribution influences balance and proportion. Provides the basis for considered, personalised conversations.

Cells within the dermis that produce collagen, elastin and other supporting components. Fibroblast activity influences how skin maintains structure and repairs itself.

A six-point classification of skin types based on how skin typically responds to UV exposure. It is one of several factors clinicians consider when assessing suitability for light-based or resurfacing treatments.

Signalling molecules that the body uses to regulate cell renewal and repair. Topical formulations aim to support the skin's natural processes and are best chosen with professional guidance.

An ingredient that attracts and holds water within the skin, such as hyaluronic acid or glycerin. Often layered under an occlusive moisturiser to help maintain hydration.

A humectant naturally found in the skin and used in topical formulations to help bind water at the surface. Most useful when paired with a moisturiser that supports the barrier.

Excessive sweating beyond what is needed for temperature regulation. A consultation can assess individual presentation, discuss potential contributing factors and outline what management options may be appropriate.

A general term for patches of skin that appear darker than the surrounding area due to increased melanin. Causes include sun exposure, hormonal changes and inflammation; assessment helps guide a considered approach.

The deepest layer of skin, made up of fat and connective tissue. It cushions underlying structures, helps regulate temperature and contributes to overall facial contour.

A clear, documented agreement made after a practitioner has explained the nature, expected outcomes, risks, alternatives and aftercare of a proposed treatment. Consent should always be unhurried.

An assessment focused on the jaw and surrounding musculature, including factors such as clenching or grinding. Provides a structured conversation about whether any considered options may be appropriate.

A category of light-based skin therapy that uses specific wavelengths to support skin comfort and recovery. Often included as part of a broader, personalised treatment plan after consultation.

Treatments that use defined wavelengths of light to support a range of skin concerns. Suitability depends on individual skin and is assessed during consultation, with realistic outcomes discussed openly.

Skincare formulations typically dispensed through clinics, with higher concentrations of active ingredients and clinical evidence behind them. Best introduced with professional guidance.

The pigment produced by melanocytes that gives skin, hair and eyes their colour and provides some protection against UV. Variations in melanin influence how the skin responds to sun exposure and certain treatments.

Cells located mainly in the lower epidermis that produce melanin. Their activity can be influenced by UV exposure, inflammation and hormonal changes.

A pattern of pigmentation that often appears symmetrically on the face, frequently associated with hormonal changes and sun exposure. Requires a careful, individualised approach assessed in consultation.

A controlled treatment that creates microscopic channels in the skin to support the body's natural repair response. Suitability, frequency and expectations are discussed during consultation.

Small, firm, white bumps that can appear when keratin becomes trapped beneath the skin's surface. A professional can confirm what they are and discuss appropriate management.

A sunscreen that uses zinc oxide and/or titanium dioxide to help reflect and scatter UV. Often well tolerated by sensitive skin and frequently recommended in the post-treatment period.

A topical product that supports the skin's hydration and barrier through a combination of humectants, emollients and occlusives. Texture preferences often change with the seasons in Brisbane.

A form of vitamin B3 included in many skincare formulations to support a comfortable, even-looking complexion. Generally well tolerated and often paired with other supportive ingredients.

An ingredient that forms a protective layer on the skin's surface to slow water loss, such as petrolatum or certain plant-based waxes. Often used as the final step in a recovery-focused routine.

Applying a small amount of a new product to a discreet area of skin to monitor for a reaction before broader use. A simple step that can prevent avoidable irritation.

Short chains of amino acids included in skincare to communicate with skin cells and support a healthier-looking complexion. Different peptides aim to support different functions.

Healthy skin tends to maintain a slightly acidic surface, which supports the barrier and microbiome. Cleansers and treatments that respect this range are generally better tolerated long term.

Visible changes to the skin associated with long-term UV exposure, including pigmentation, texture changes and loss of resilience. Daily sun protection is the most important strategy to help limit it.

A gentler class of exfoliating acid, including gluconolactone and lactobionic acid, often suitable for more sensitive skin or as an introduction to acid-based exfoliation.

Darkening of the skin that can occur after inflammation, such as blemishes or trauma. More common in deeper skin tones and best approached gently after professional assessment.

A family of vitamin A derivatives, including retinol, that support skin cell turnover. Best introduced gradually and paired with diligent sun protection.

A widely used over-the-counter retinoid. Effects build over time with consistent use, and a slow, considered introduction helps reduce irritation.

The natural oil produced by sebaceous glands that helps lubricate and protect the skin. Production varies between individuals and is influenced by genetics, hormones and environment.

The skin’s protective outer layer that helps retain moisture and defend against irritants. A well-supported barrier looks and feels calmer and tolerates active ingredients more reliably.

A treatment philosophy focused on restoring barrier function, hydration and overall resilience using a layered, evidence-informed approach tailored at consultation.

The community of microorganisms that live on the skin's surface and contribute to a balanced, healthy-looking complexion. Harsh routines can disturb this balance.

Sun Protection Factor — a measure of how much UVB protection a sunscreen provides when applied at the tested rate. SPF 30 or higher is recommended daily in Brisbane, with regular reapplication when outdoors.

The outermost layer of the epidermis, made up of flattened cells and lipids. It plays a key role in barrier function and how the skin appears at the surface.

A combined strategy that includes broad-spectrum sunscreen, protective clothing, hats, sunglasses and shade. The most consistent way to support long-term skin health, especially in Queensland's UV climate.

Visible small, dilated blood vessels near the skin's surface, often appearing on the cheeks or nose. A consultation can help identify likely contributors and discuss appropriate options.

The natural movement of water from inside the body out through the skin. Elevated TEWL can be a sign of a compromised barrier and skin that may benefit from gentler, more supportive care.

An antioxidant used topically to help defend the skin against environmental stress and support a brighter-looking complexion. Stability, concentration and packaging influence performance.
