GENTLE MANDELIC EXFOLIATION FOR CLEARER, MORE BALANCED-LOOKING SKIN

The Mandelic Meta Serum by Biba Los Angeles is a professional-grade mandelic acid serum designed to support gentle, controlled exfoliation while helping improve texture, visible congestion, uneven tone, and the appearance of pores without disrupting the skin barrier. Combining mandelic acid and lactic acid with niacinamide, hyaluronic acid, and skin-identical humectants, the formula helps refine and clarify the skin while supporting hydration balance and overall skin comfort.

WHY THIS MANDELIC ACID SERUM WORKS DIFFERENTLY

Mandelic acid is a larger-molecule alpha hydroxy acid (AHA) that penetrates the skin more gradually than many stronger exfoliating acids, making it more predictable and generally easier for reactive or acne-prone skin to tolerate. Rather than relying on aggressive resurfacing, The Mandelic Meta Serum was developed around controlled exfoliation that helps loosen buildup, refine uneven texture, support clearer-looking pores, and improve the appearance of uneven tone while maintaining hydration and barrier balance.

GRADUAL REFINEMENT WITHOUT OVER-PROCESSING

Unlike harsher exfoliating treatments that can leave the skin reactive, dehydrated, or difficult to balance, this formula works gradually to improve the appearance of congestion, discoloration, uneven tone, and rough texture over time. Niacinamide, hyaluronic acid, and hydration-supportive ingredients help maintain overall skin comfort while supporting smoother, calmer, and more refined-looking skin. The result is skin that appears clearer and more balanced without the excessive irritation often associated with aggressive exfoliation.

GRADUAL EXFOLIATION FOR LONG-TERM SKIN BALANCE

Developed from Biba de Sousa’s hands-on experience treating acne-prone, reactive, congestion-prone, and over-processed skin, The Mandelic Meta Serum was designed for skin that benefits from exfoliation but struggles with stronger resurfacing products. It is especially well suited for acne-prone skin, visible congestion, uneven texture, discoloration, and skin that requires a gentler approach to ongoing exfoliation maintenance.

HOW TO USE

The Mandelic Meta Serum


Apply the Mandelic Meta Serum 1–2 times per week at night, after cleansing and before moisturizer. As your skin adjusts, you may gradually increase to every other night or nightly use, depending on your skin’s response.

If stinging or irritation occurs, discontinue use for 2–3 days to allow the skin barrier to recover, then resume use with reduced frequency. Always follow with a hydrating moisturizer and apply SPF 30+ daily, even on days when you are not using the serum. Avoid layering with other strong actives (like retinol or exfoliating acids) on the same night, especially in the beginning.
