Murad Biome-Balancing Acne Treatment Serum — Salicylic & Mandelic Acid, 1.0 fl oz, Lightweight Clarifying Formula

This targeted acne serum blends proven exfoliating acids with a microbiome-supporting ingredient system designed to reduce active breakouts and help skin stay clearer over time. The formula pairs salicylic acid to penetrate and clear clogged pores, mandelic acid to smooth and even skin tone, and glutamic acid to nourish the skin’s microbial community so it can better resist future congestion. It’s packaged as a 1.0 fl oz treatment intended for regular use on oily, combination, and acne-prone skin types.

How does this serum address current breakouts?

The serum relies on salicylic acid to reach inside blocked pores and loosen the debris that contributes to pimples and whiteheads. Mandelic acid complements this by providing surface exfoliation that brightens and refines texture without heavy irritation. Together, they work to shorten the life cycle of blemishes while improving overall skin clarity.

• Salicylic acid penetrates pores to decongest and reduce build-up.
• Mandelic acid gently resurfaces for smoother, more even skin.
• Non-comedogenic formula minimizes risk of further clogging.
• Lightweight serum texture layers under makeup without pilling.

What is biome-sensing technology and why is glutamic acid included?

Biome-sensing technology refers to ingredients that support a healthier balance of skin microbes rather than indiscriminately stripping them. Glutamic acid acts as a nutritional substrate that encourages production of beneficial metabolites, helping the microbiome perform protective roles. This approach aims to reduce recurrence of breakouts by promoting a more resilient microbial environment.

• Biome-sensing system supports microbiome balance instead of disrupting it.
• Glutamic acid helps feed beneficial microbes for healthier-looking skin.
• Designed to be gentle so daily application is tolerable for many users.
• Does not rely on harsh antiseptics that can oversensitize skin.

Will this serum irritate or dry out my skin?

The formula is designed to avoid excessive dryness and irritation: it’s non-drying, non-irritating, and non-comedogenic, making it suitable for repeated use when introduced appropriately. Because it contains active acids, start with less frequent application if you have sensitive skin and increase as tolerated. It layers well beneath makeup and is formulated to resist pilling or flaking.

• Non-drying and formulated to minimize irritation risks.
• Works under makeup without creating flakes or pills.
• Recommended to patch test and build frequency gradually.
• Suitable for daily use once skin has acclimated to acids.

How should I incorporate this into my routine for best results?

Use this serum after cleansing and before moisturizers or sunscreens to allow active acids direct contact with the skin. Start with a few times per week, increasing to nightly use if tolerated; always follow with SPF in daytime routines because acids can increase sun sensitivity. Combine with gentle cleansers and non-comedogenic moisturizers to support barrier health while treating acne.

• Apply to clean, dry skin before heavier creams or oils.
• Begin usage slowly (every other night), then adjust frequency.
• Always use broad-spectrum SPF during the day.
• Pair with mild supporting products to avoid over-exfoliation.

Who is this for: This serum is intended for people with oily, combination, or acne-prone skin looking for a treatment that addresses active blemishes while supporting longer-term microbiome balance. It’s suited to users comfortable introducing exfoliating acids into their routine and those who prefer targeted, non-comedogenic products that layer under makeup. If you have very sensitive or barrier-compromised skin, consult a dermatologist before adding new acid-based actives.
