DRMTLGY Lactic Acid 12% Refining Serum for Face, 1 oz — AHA+PHA Exfoliant with Licorice for Dark Spots & Smoother Texture

DRMTLGY Lactic Acid 12% Refining Serum is a concentrated AHA + PHA exfoliating serum that helps resurface skin, reduce the look of dark spots, and improve texture.

This lightweight, milky serum combines 12% lactic acid with gluconolactone (a gentle PHA) and licorice root extract to promote smoother-looking skin and a more even tone. Designed as an at-home chemical exfoliant, it targets buildup, dullness, and uneven texture while supporting brighter-looking skin. Formulated in the USA and cruelty-free, the 1 oz bottle delivers a potent dose intended for nighttime use or occasional mask-style applications for sensitive skin.

How does this serum improve skin texture and tone?

The lactic acid in the formula loosens bonds between dead surface cells so they shed more easily, while gluconolactone provides a milder, longer-acting exfoliation. Licorice root extract helps visually even skin tone, working alongside the acids to reduce the appearance of dark spots over time. Regular, controlled use encourages fresher, smoother-looking skin without physical abrasion.

• 12% lactic acid concentration for chemical resurfacing
• Gluconolactone (PHA) for gentler exfoliation and hydration support
• Licorice root extract to help brighten and even discoloration
• Non-abrasive, milky texture suitable for layered skincare routines

When and how should I incorporate it into my routine?

Use this serum in low frequencies at first—start with once or twice weekly at night and increase as tolerated. Apply to clean, dry skin after cleansing and before heavier creams or oils. Always follow with daily sunscreen, as AHAs can increase sun sensitivity.

• Begin with patch testing and one application weekly
• Apply on clean skin; wait before layering moisturizers
• Use SPF daily during the treatment period to protect new skin
• For sensitive skin, use as a 15-minute mask rather than leave-on

Is this serum suitable for sensitive or acne-prone skin?

The combined AHA and PHA approach balances strong resurfacing with milder, hydrating exfoliation, which can be better tolerated than AHAs alone. Those with sensitive or easily irritated skin should limit contact time and frequency, or use it as a rinse-off mask to gauge tolerance. People prone to active acne may see reduced congestion over time due to exfoliation, but avoid using with other strong actives until tolerance is established.

• PHA component reduces irritation risk compared to high-strength AHAs alone
• Recommended mask use for sensitive skin to control exposure
• Avoid simultaneous use with retinoids or strong acids initially
• Patch test behind the ear or inner forearm before full-face use

What results and timeframe can I reasonably expect?

Visible improvements in texture and brightness commonly appear within a few weeks of consistent use, while more pronounced reduction in dark spots typically requires several weeks to months. Individual results vary by skin type, prior sun damage, and frequency of use. Gradual, steady use paired with sun protection yields the best long-term outcomes.

• Texture and radiance: often noticeable within 2–4 weeks
• Dark spot reduction: commonly seen over multiple weeks of continued use
• Maintains smoother skin when used regularly and with SPF
• Results depend on adherence and initial skin condition

Who is this for: DRMTLGY Lactic Acid 12% Refining Serum is aimed at adults looking to chemically exfoliate at home to address dullness, uneven texture, and the appearance of dark spots. It's a fit for people comfortable introducing a professional-strength acid into their nighttime routine, those transitioning from physical scrubs to chemical exfoliants, and anyone who prioritizes gradual brightening with sunscreen protection. If your skin is highly reactive or you use multiple strong actives, consult a skincare professional and consider shorter contact times or mask applications to build tolerance.
