Neutrogena Blackhead Acne Facial Serum, 1 fl oz — Multi-Acid (Salicylic, Glycolic) Oil-Free Treatment

Designed for oily and acne-prone skin, this lightweight 1 fl. oz. serum from Neutrogena uses a multi-acid approach to exfoliate the skin surface and inside pores. The formula layers easily under moisturizer or makeup, is free of fragrances and common irritants, and aims to reduce visible blackheads and breakouts when used as directed. Its concentrated acid complex brings several exfoliating mechanisms together so you can address stubborn congestion without heavy oils.

How does this serum work to clear blackheads and prevent new breakouts?

The serum combines different acids that each play a role: salicylic acid penetrates pores to dissolve oil and debris, glycolic acid loosens surface buildup for exfoliation, mandelic acid offers gentler exfoliation, and polyhydroxy acid provides clarifying action with a softer feel. Together they help dislodge pore plugs and reduce the factors that contribute to acne and blackheads.

• 0.5% salicylic acid (BHA) to reach and clear oily follicles
• 5% glycolic acid to shed dead skin cells and refine texture
• 2.5% mandelic acid for milder exfoliation and tolerance
• 2.5% polyhydroxy acid for gentle surface smoothing and hydration support

When and how should I use the Neutrogena blackhead serum in my routine?

Apply a thin layer to clean, dry skin on affected areas after cleansing and before heavier creams or makeup. Start with once daily to assess tolerance, then increase to up to three times a day if your skin tolerates it; always follow with sunscreen in the daytime because acids can increase sun sensitivity.

• Use after cleansing and before moisturizer or makeup
• Begin with once daily; increase gradually to up to three times per day as tolerated
• Pair with daily SPF during daylight hours to protect renewed skin

Is this serum suitable for sensitive or combination skin types?

The formula is fragrance-free, oil-free, and free from parabens, phthalates, dyes and sulfates, which reduces the risk of irritation for many users. However, because it contains active acids, those with sensitive or reactive skin should patch-test first and introduce the product slowly to monitor tolerance.

• Hypoallergenic and non-comedogenic formulation
• Fragrance- and dye-free to minimize irritation triggers
• Patch-test recommended for sensitive or reactive skin types

What results can I expect and how long until I see changes?

Visible reduction in clogged pores and fewer blackheads typically appears after consistent use, though timing varies by individual skin condition and routine adherence. Many users notice improvements in texture and fewer congested pores within a few weeks when the serum is used as part of a regular acne-care routine.

• Helps reduce the appearance of blackheads and clogged pores with ongoing use
• Supports clearer skin texture by combining surface and pore-level exfoliation
• Works best when used regularly and with sun protection

Who is this for: This Neutrogena Stubborn Blackheads serum is made for people with oily or acne-prone skin seeking a targeted, non-oil treatment to address persistent blackheads and pore congestion. It suits those comfortable using acid-based exfoliants and anyone wanting a lightweight product that layers under moisturizer or makeup. If you have highly reactive skin, consult a dermatologist before regular use and introduce the serum gradually to ensure tolerance.
