What is Salicylic Acid?

Salicylic acid is a beta hydroxy acid (BHA). It is oil-soluble. This means it can penetrate deep into your pores. Once inside, it exfoliates dead skin cells and unclogs pores. It comes from willow bark. You can find it in many acne treatments, cleansers, and toners.

How Salicylic Acid Works

Salicylic acid dissolves the oil and debris inside your pores. It also helps remove dead skin cells from the surface. This makes it great for preventing blackheads and whiteheads. It also improves skin texture over time.

Common Uses of Salicylic Acid

  • Acne (especially blackheads and whiteheads)
  • Keratosis pilaris (small bumps on arms or thighs)
  • Seborrheic dermatitis (scaly patches on the scalp or face)
  • Warts (in higher concentrations)

What is Zinc?

Zinc is an essential mineral. Your body needs it for many functions, including skin health. It has anti-inflammatory and antimicrobial properties. This means it can reduce redness, swelling, and fight bacteria. Zinc is found in creams, ointments, and supplements.

How Zinc Works

Zinc calms inflammation. It also helps control oil production. It can kill acne-causing bacteria. It also helps wounds heal faster. This makes it useful for many skin conditions.

Common Uses of Zinc

  • Acne (especially inflammatory types)
  • Rosacea
  • Eczema
  • Diaper rash
  • Sunburn
  • Wound healing
