Ketostat 20% Salicylic Acid Serum 2 fl oz — Professional-strength BHA Exfoliant, Clean & Cruelty-Free

Ketostat 20% Salicylic Acid Serum is a potent, two-ingredient exfoliating serum that delivers concentrated BHA to unclog pores, smooth texture, and support a clearer-looking complexion.

This professional-strength serum combines high-concentration salicylic acid with a simple carrier to offer a focused, fast-absorbing treatment for oily, textured, or acne-prone skin. The formula is clean and cruelty-free, free from parabens, sulfates, and synthetic fragrances, and comes in a generous 2 fl oz bottle for extended use. Because it is a concentrated chemical exfoliant, a patch test and daytime sunscreen are recommended when used as part of your routine.

How should I use a 20% salicylic acid serum safely?

Apply sparingly and initially use no more than once or twice a week to assess tolerance. Always perform a patch test, avoid eye contact, and stop use if persistent irritation occurs; follow with SPF during daytime use to protect newly exposed skin.

• Patch-test on inner forearm for 24 hours before full-face application
• Start with a pea-sized amount for targeted areas or dilute with a moisturizer if sensitivity appears
• Use in the evening or under sunscreen during the day
• Do not mix directly with strong acids or retinoids without professional guidance

What results can I expect and how quickly?

Visible texture refinement and fewer clogged pores can appear after a few uses, while consistent weekly use may reveal smoother skin over several weeks. Individual timelines vary with skin type and prior exfoliation habits.

• Initial smoothing often within 1–2 weeks for many users
• Reduction in surface congestion with continued weekly use
• Complementary to a simple routine: cleanse, treat, moisturize, and protect

How does this formula fit into my existing skincare routine?

Because the serum is a targeted exfoliant, it pairs best with gentle cleansers and hydrating moisturizers rather than multiple active products on the same day. Reserve other actives like strong retinoids or vitamin C for alternate nights to minimize irritation.

• Use on clean, dry skin after cleansing and before heavier creams
• Combine with soothing, fragrance-free moisturizers to support barrier health
• Alternate with other potent actives to avoid over-exfoliation

What are the product’s safety notes and ingredient highlights?

This serum contains a pure 20% salicylic acid concentration in a minimal carrier for effective penetration. It is formulated without parabens, sulfates, or synthetic fragrances, and is cruelty-free; however, it is for external use only and should not touch the eyes.

• Active ingredient: Salicylic Acid (20%) — a beta hydroxy acid (BHA)
• Clean label: paraben-, sulfate-, and fragrance-free
• Cruelty-free manufacturing and testing standards
• Always patch-test and discontinue if irritation occurs

Who is this for: Ketostat 20% Salicylic Acid Serum is designed for experienced exfoliant users, and people with oily, textured, or acne-prone skin who are seeking a high-strength, straightforward treatment.
