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

CLEARSTEM CLEARITY Blackhead Dissolver is an 8% mandelic acid serum formulated to gently exfoliate, reduce visible blackheads, and brighten skin with stabilized vitamin C and supportive botanicals.

This lightweight serum blends mandelic acid with vitamin C bioflavonoids, turmeric, and collagen-supporting ingredients to target pore congestion and surface dullness without harsh irritation. The formula is designed with a measured acid blend and controlled pH to help loosen trapped oil and dead skin cells while also delivering antioxidant support. Because it contains stabilized vitamin C, it can replace a separate vitamin C product in your routine. The serum is cruelty-free, gluten-free, and non-comedogenic.

How quickly will I notice blackheads and pore congestion improving?

Some users report visible changes after a single application once the serum has had time to act, but consistent results typically appear with regular nightly use over 1–3 weeks. Start slowly to allow your skin to adapt to exfoliation.

• Initial visible softening of blackheads in minutes to hours for some skin types.
• Clearer pores and reduced buildup with 10–14 days of steady use.
• Best results when introduced gradually: nights only for the first 1–2 weeks.

Is this serum suitable for sensitive or combination skin?

The mandelic acid base is an alpha hydroxy acid known for larger molecular size and gentler penetration compared with some AHAs, making it a common choice for sensitive or combination skin. Still, patch testing and gradual introduction help manage sensitivity risks.

• Start with every-other-night or nighttime-only use for the first week or two.
• Perform a patch test behind the ear or inner forearm before full-face application.
• Follow with moisturizer and sunscreen during daytime to support barrier recovery.

Can I combine this with other active ingredients like retinol or vitamin C serums?

This formula already includes stabilized vitamin C bioflavonoids, so a separate vitamin C serum is usually unnecessary. When pairing with more actives, spacing applications and monitoring tolerance reduces irritation risk.

• Avoid layering strong exfoliants or starting retinoids on the same night you apply this serum.
• Introduce retinol gradually and alternate nights if combining treatments.
• Always apply sunscreen daily when using chemical exfoliants to protect renewed skin.

How should I incorporate the serum into my skincare routine?

Apply the serum after cleansing and before heavier moisturizers or oils. Because it’s an active exfoliant, begin with short-term nightly use and only increase frequency once your skin tolerates it.

• Cleanse thoroughly, then apply a few drops of serum to dry skin at night.
• Use sunscreen during the day; limit sun exposure while using chemical exfoliants.
• After 10–14 days of nighttime-only use, consider adding a morning application if skin is comfortable.

Who this is for: CLEARSTEM CLEARITY is aimed at people seeking a targeted, non-abrasive solution for blackheads, congested pores, and surface dullness—suitable for most skin types including combination and sensitive-prone skin when introduced gradually. It’s a good match for anyone who prefers multifunctional products (exfoliation plus antioxidant support), wants gluten- and cruelty-free formulations, and values a measured, science-minded approach to resurfacing and brightening within a daily skincare routine.
