Dull skin occurs when dead skin cells accumulate on the surface, blocking light reflection and creating a lackluster appearance.

Acne develops when hair follicles become clogged with oil, dead skin cells, and bacteria, leading to inflammation and breakouts.

Hyperpigmentation occurs when excess melanin production creates dark patches or spots on the skin, triggered by sun exposure, inflammation, hormonal changes, or injury.

Uneven skin tone results from irregular melanin distribution, sun damage, post-inflammatory marks, aging, and texture irregularities that create patches of varying color and smoothness.

Skin dryness occurs when the skin barrier loses moisture faster than it can be replenished, caused by harsh weather, low humidity, hot showers, aging, or lack of proper hydration.

Aging skin results from decreased collagen and elastin production, cellular damage from free radicals, sun exposure, and natural moisture loss over time, causing wrinkles, fine lines, and sagging.
