We all want healthy, younger-looking skin with fewer breakouts, smaller pores, and a smooth texture. Many products push expensive, complicated routines—but that’s mostly marketing. A simple routine can make a big difference.

Dandruff is common and frustrating, causing flakes, itching, or both. Medicated shampoos with ketoconazole, selenium sulfide, or zinc pyrithione can really help—if you use them the right way.

Post-inflammatory hyperpigmentation is darkening of skin after inflammation or injury. It doesn’t itch or hurt, but it can be bothersome and worsens with sun exposure. Over-the-counter treatments plus daily sun protection can help fade it.

Acne comes in two main types: blackheads/whiteheads and pimples/cysts. Each type needs different care, but effective over-the-counter treatments are available if used correctly.

Seborrheic dermatitis, the rash behind dandruff, is common and often itchy with visible flakes. Medicated dandruff shampoos work well—if used properly.

Scalp dandruff is common and irritating, and the same rash can also affect the face. Medicated dandruff shampoos help a lot—if used the right way. Learn more here.

Dry feet are common in winter and summer, especially cracked heels, which can be painful when soaps, dirt, or chemicals get in. Over-the-counter products can help a lot.

Folliculitis is red bumps or pimples that often appear after shaving. Common areas include the scalp, neck, chest, back, and inner thighs. It can resemble acne and usually improves with similar treatments.

Pseudofolliculitis, also called razor bumps, is red bumps that appear after shaving, waxing, or plucking. It’s more common in curly hair, especially in skin of color, when hairs curl back into the skin, causing irritation, redness, and sometimes dark marks or scars.
