La Roche-Posay Glycolic Acid Dark Spot Serum, 30 ml — 10% Glycolic Acid & Vitamin B5

La Roche-Posay Glycolic Acid Dark Spot Serum is a lightweight 1 oz facial serum combining 10% glycolic acid with tranexamic and kojic acids plus vitamin B5 to help exfoliate, fade dark spots, and reveal a more even-looking complexion.

This clinically tested serum uses a triple-acid approach—pure glycolic acid, TXA (tranexamic acid) and kojic acid—alongside soothing panthenol (vitamin B5) to refine skin texture and target visible discoloration. Formulated to be non-comedogenic, alcohol-free and fragrance-free, the product is designed for evening use and pairs with daily SPF. Clinical results reported brighter skin in two weeks and reduced appearance of dark spots within four weeks when used as directed.

How does this serum help reduce dark spots and uneven tone?

The formula combines exfoliation and targeted pigment-modulating actives to address surface discoloration and accelerate skin renewal. Glycolic acid promotes the shedding of dull surface cells while tranexamic and kojic acids work to minimize the look of pigment formation for a more uniform tone.

• 10% pure glycolic acid for chemical exfoliation and texture smoothing
• Tranexamic acid (TXA) to help address the appearance of discoloration
• Kojic acid to help visibly reduce hyperpigmentation
• Vitamin B5 (panthenol) to soothe and support skin hydration

When and how should I use this serum safely?

Apply 3–4 drops in the evening to clean, dry skin, avoiding the immediate eye area. Because glycolic acid increases sun sensitivity, pair nightly use with a broad-spectrum SPF during daytime and introduce the product gradually if you have sensitive skin.

• Evening application only; start with alternate nights if new to AHAs
• Use 3–4 drops applied across face, then follow with moisturizer
• Always use daily SPF while using the serum
• Patch test if you have reactive or highly sensitive skin

Is this suitable for sensitive skin and multiple skin tones?

The formula is dermatologically tested, fragrance-free, and labeled suitable for sensitive skin and various skin tones, but active exfoliation can still cause irritation for some. The inclusion of panthenol helps calm skin, and the product is non-comedogenic and oil-free for broad compatibility.

• Fragrance-free and allergy tested for gentler use
• Non-comedogenic and oil-free to reduce pore congestion
• Accommodates multiple skin tones; monitor results and tolerance
• Consider slower introduction if you are on retinoids or other acids

What results can I realistically expect and on what timeline?

Clinical observations indicate visible radiance improvements in about two weeks and noticeable reduction of dark spots by four weeks, when used consistently. Individual response varies with skin type, severity of discoloration, and concurrent skincare steps.

• Brighter-looking skin reported after approximately two weeks
• Reduction in the look of dark spots and discolorations around four weeks
• Best results when used nightly with daytime SPF protection
• Combine with a gentle cleanser and moisturizer for balanced care

Who is this for: This serum suits anyone seeking to reduce the appearance of post-acne marks, sunspots, or uneven tone who is comfortable using an active exfoliant. It's geared toward users looking for a dermatologically tested formula that blends chemical exfoliation with pigment-targeting acids and soothing panthenol—appropriate for many skin tones and for those who will commit to evening use plus daytime sun protection.
