Skincare Key Ingredients: A Guide to Effective Beauty

Korean brands focus on hydration, prevention, and skin barrier care instead of just covering imperfections. They often use natural extracts like green tea, centella asiatica, snail mucin, and fermented ingredients.

Moisturizing / Soothing Ingredients

Aloe Vera

Aloe Vera is a powerful soothing agent that relieves irritation, heals sunburns, and hydrates the skin without clogging pores.
 Best for: Sensitive, dry, or sun-exposed skin.

Known for its healing and anti-inflammatory properties, Centella Asiatica calms irritation, promotes wound healing, and strengthens sensitive skin.
 Best for: Sensitive, irritated, or acne-prone skin.

Ceramides are lipids (fats) that occur naturally in the skin and are essential for maintaining its protective barrier. They help retain moisture, prevent dryness, and protect the skin from external irritants. Using ceramides in skincare restores the skin barrier, making it ideal for treating sensitivity, dehydration, and conditions like eczema or rosacea.

Best for: Dry, sensitive, or compromised skin.

Collagen enhances skin firmness, smooths wrinkles, and supports youthful-looking skin. It maintains moisture levels and improves texture.
 Best for: Mature, dry, or sagging skin.

 A super hydrator that attracts and retains moisture in the skin, making it plump and smooth. Perfect for reducing fine lines and dryness.
 Best for: Dry, dehydrated, or aging skin.

Active Ingredients

Acids (AHA / BHA / PHA) – Exfoliating Actives
AHA (Alpha Hydroxy Acids)

AHAs (like glycolic or lactic acid) are water-soluble acids that gently exfoliate the surface of the skin. They promote cell turnover, brighten dull complexion, and improve texture and hydration.
 Best for: Dry, dull, or uneven skin.

BHA (Beta Hydroxy Acid – Salicylic Acid)

BHAs are oil-soluble acids that penetrate deep into the pores to clear sebum, blackheads, and impurities. They reduce inflammation and help treat acne.
 Best for: Oily, acne-prone, and congested skin.

PHA (Polyhydroxy Acids)

PHAs are gentle exfoliants with larger molecules that act on the skin’s surface, offering mild exfoliation with added hydration. They are ideal for sensitive skin.
 Best for: Sensitive, dry, or irritated skin.

Bakuchiol is a plant-derived compound often called a natural alternative to retinol. It helps reduce fine lines and wrinkles, evens out skin tone, and improves firmness—without the irritation retinol can cause. It’s safe for daily use and suitable even for sensitive skin.
 Best for: Sensitive, aging, or uneven skin.

Galactomyces ferment filtrate is a powerful fermented ingredient rich in vitamins, amino acids, and enzymes. It helps brighten the complexion, tighten pores, balance oil production, and strengthen the skin barrier. It enhances skin clarity and smoothness over time.
 Best for: Combination, oily, or dull skin.

Niacinamide helps reduce enlarged pores, brightens skin tone, regulates oil production, and strengthens the skin barrier. It’s a multitasking ingredient ideal for maintaining healthy skin.
 Best for: All skin types, especially combination, oily, and dull skin.

Peptides boost collagen synthesis, improve skin resilience, and combat signs of aging. They support skin firmness and a youthful appearance.
 Best for: Mature, tired, or sagging skin.

Retinol is a derivative of vitamin A known for its powerful anti-aging effects. It accelerates skin cell turnover, reduces the appearance of fine lines and wrinkles, unclogs pores, and improves skin texture and tone. Over time, it helps smooth rough patches and fade dark spots caused by sun damage or acne. Retinol can initially cause dryness or irritation, so it’s best introduced gradually.

Best for: Mature, oily, or acne-prone skin (avoid during pregnancy).

Snail mucin promotes skin regeneration, improves elasticity, and deeply hydrates. It helps repair damaged skin, fade scars, and reduce fine lines.
 Best for: All skin types, especially damaged or aging skin.

Vitamin C is a potent antioxidant that helps brighten the complexion, fade hyperpigmentation, and stimulate collagen production. It protects the skin against environmental damage from pollution and UV rays, giving it a radiant and even-toned appearance. Vitamin C also supports the skin’s natural regeneration process and enhances overall skin glow.

Best for: Dull, uneven, pigmented, or aging skin
