CLEARSTEM Mandelic Acid Blackhead Dissolver Serum 40ml — 8% AHA, Stabilized Vitamin C Brightening

CLEARSTEM CLEARITY Blackhead Dissolver is an 8% mandelic acid serum formulated to gently exfoliate, unclog pores, and brighten skin while delivering stabilized vitamin C.

This lightweight serum blends mandelic acid with a carefully balanced acid complex, stabilized vitamin C bioflavonoids, and supporting botanicals like turmeric to target blackheads, excess oil, and dullness without harsh irritation. Designed for all skin types and packaged as a non-comedogenic, gluten-free, cruelty-free formula, it serves as both an exfoliant and a brightening treatment in a single 40 ml bottle.

How quickly will I notice blackheads diminishing?

Many users report visible softening or reduction of blackheads within a short application window, especially when used consistently. The mandelic acid works to loosen debris in pores while the formula's pH and acid blend encourage gentle surface exfoliation for faster results than milder everyday cleansers.

• Visible softening often reported within 10 minutes of application on targeted areas.
• Consistent nightly use for 10–14 days improves overall pore clarity.
• Combination of acid blend and balanced pH reduces buildup without over-stripping.

Is this safe for sensitive or acne-prone skin?

The serum uses mandelic acid, an AHA known for being gentler than some stronger acids, making it a good candidate for sensitive or acne-prone skin when introduced gradually. Start with night-only applications and monitor skin response; reduce frequency if redness or discomfort occurs until tolerance builds.

• Begin with once-nightly use for the first week or two to allow skin to adjust.
• Patch-test behind the ear or inner forearm before full-face use.
• Non-comedogenic formulation reduces risk of pore-clogging reactions.

Can this replace my vitamin C serum and how should I layer it?

Because the formula contains stabilized vitamin C bioflavonoids, you typically don’t need a separate vitamin C product in the same routine. In the morning use a dedicated sunscreen after the serum; at night it can be used alone or as the active step after cleansing and before moisturizers.

• Contains stabilized vitamin C—skip an extra vitamin C serum to avoid layering actives.
• Use after cleansing and toning, before richer creams or oils.
• Apply sunscreen during the day when acids are used regularly.

How should I introduce this into my skincare routine?

Introduce the serum gradually to minimize irritation: apply at night only for the first 7–14 days, then increase frequency or add a morning application if tolerated. Keep other strong actives (like retinoids or high-concentration acids) spaced apart to reduce sensitivity.

• Week 1–2: night use only, 2–3 times weekly if very reactive.
• After tolerance builds: nightly or morning and night per product guidance.
• Avoid combining with other exfoliating treatments on the same night.

Who is this for: CLEARSTEM CLEARITY is aimed at anyone seeking a targeted solution for blackheads and dull skin—especially people looking for a gentler AHA option that also delivers brightening with stabilized vitamin C. It suits all skin types if introduced carefully, and is a good fit for those who prefer multi-benefit serums in a gluten-free, cruelty-free, non-comedogenic formula. Avoid if you have a known allergy to any listed ingredients; consult a dermatologist for complex skin conditions or if you use prescription actives.
