When new pimples keep appearing before the old marks fade, your skin can feel stuck in a cycle. The Salicylic Azelaic Acne & Marks Duo tackles both sides of that cycle: treating the clogged pores and breakouts while helping clear the redness and dark spots they leave behind. This bundle is especially useful when acne is stubborn or your skin is prone to dark marks after every pimple.

Our Salicylic Acid Serum combines 1.5% salicylic acid with glycolic acid to treat congestion at two levels. Salicylic acid works inside oily pores, loosening the dead skin that contributes to blackheads, whiteheads and recurring bumps. Glycolic acid lifts dead cells from the surface, helping smooth rough texture and improve uneven tone. Together, they address both the blocked pores underneath and the roughness you can see and feel.

The Azelaic Acid Serum adds a different kind of treatment. Its 10% potassium azeloyl diglycinate (PAD) is a water-soluble azelaic acid derivative that helps manage excess oil and blemish-prone skin while reducing redness and supporting a more even skin tone. It earns its place as an acne treatment as well as a treatment for marks, making it particularly valuable when breakouts and pigmentation overlap.

The strength of this pairing comes from those complementary roles. Salicylic and glycolic acids help clear congestion and improve skin texture, while PAD adds support for oil control, redness and post-acne pigmentation. You are addressing more of the reasons your skin remains bumpy and uneven, rather than relying on more exfoliation alone.

Both formulas also make room for skin comfort. The salicylic serum’s emulsion base contains urea, panthenol and oats to help hydrate and soothe skin during treatment. The azelaic serum pairs PAD with glycerin, panthenol, hyaluronic acid and allantoin for lightweight hydration and soothing care. Introduce the serums gradually, alternating them initially, and keep moisturiser and daily sunscreen in your routine. Consistent treatment helps keep pores clearer while giving lingering marks time to fade.

Start with Salicylic Acid Serum 2–3 nights a week, applying a small amount to clean, dry skin before moisturiser. If your skin is sensitive, start with one drop on congested areas just 1–2 nights a week, applying moisturiser first to soften the intensity of the treatment.

Once your skin is comfortable with this for a few weeks, introduce Azelaic Acid Serum on the alternate nights. Apply 2–3 drops to clean, dry skin, then follow with moisturiser. Start once daily on those days and increase use gradually as tolerated.

Keep the serums in separate routines initially. Avoid adding other exfoliating acids while adjusting to the duo, and use sunscreen every morning.

Salicylic Acid Serum

1.5% Salicylic Acid
An oil-soluble BHA that can work within congested pores to help clear blackheads, whiteheads, closed comedones and recurring breakouts.
This is the ingredient doing most of the pore-clearing work in the formula, making the serum particularly useful when acne has progressed beyond simple oiliness or occasional congestion.

Glycolic Acid
An AHA that complements Salicylic Acid by exfoliating more at the skin's surface.
It helps improve the rough, uneven texture and buildup that often accompanies persistent acne and congestion, giving this formula broader exfoliating activity than a Salicylic Acid-only treatment.

Urea
A highly effective skin-conditioning and humectant ingredient that helps hold water in the outer layers of the skin.

Panthenol
Also known as Pro-Vitamin B5, Panthenol helps support hydration and skin comfort.

Oats
Oats provide additional soothing and skin-conditioning support, helping cushion the feel of a formula built around two exfoliating acids.

Azelaic Acid Serum

10% Potassium Azeloyl Diglycinate (PAD)
A highly water-soluble azelaic acid derivative and the main treatment active in the formula.
PAD is a true multi-tasker for acne-prone skin: it helps with mild acne, excess sebum, redness and post-acne marks, while its excellent water solubility allows us to formulate it into a lightweight serum rather than a heavy cream or suspension.
This makes it especially useful when acne isn't your only concern — you're also dealing with the redness and pigmentation it leaves behind.

Panthenol
Also known as Pro-Vitamin B5, Panthenol helps support hydration, skin comfort and barrier function.
Its role here is particularly useful because acne-prone skin is often already exposed to salicylic acid, retinoids or other treatments that can potentially be irritating.

Hyaluronic Acid
Sodium Hyaluronate is a humectant that helps attract and retain water in the upper layers of the skin.
It keeps the formula hydration-focused and helps give the serum its comfortable everyday feel without adding heaviness.

Allantoin
A soothing, skin-conditioning ingredient included to help calm and comfort easily irritated skin.
It complements PAD particularly well for people whose acne comes with sensitivity or redness.

Cogon Grass Extract
Imperata Cylindrica Root Extract is a humectant-rich botanical used to help support skin hydration and water retention.
Together with Glycerin, Hyaluronic Acid and Panthenol, it rounds out the serum's hydration system so the formula isn't built around the treatment active alone.
