For those who want to build a basic skincare routine, oil-water balance care, or a radiance-focused routine, Vitamin B3 is an ingredient worth knowing.

【Key Takeaways】

  • Multi-purpose skincare ingredient: Vitamin B3 is commonly used in radiance, hydration, oil-water balance, and skin-conditioning products.

  • Suitable for various skin types: Oily skin, dry skin, combination skin, and delicate skin can use it according to individual tolerance.

  • Product recommendation: Vitamin B3 Topical Serum, suitable for daily skin conditioning and radiance care.


What is Vitamin B3? Why is it commonly used in skincare products?

When the skin feels dry, tight, or unstable, skincare should begin with “minimalist skincare.”

Minimalist skincare does not mean applying nothing. It means reducing skincare steps and ingredients that may burden the skin, and choosing products with clear purposes, gentle textures, hydration, and soothing benefits to help the skin gradually return to a comfortable condition.

Sensitive skin care can follow these directions:

  1. Reduce potentially irritating ingredients
    High-concentration acids, exfoliating products, alcohol, fragrance, and overly cooling formulas are recommended to be paused or used less frequently when the skin is unstable.

  2. Avoid over-cleansing
    When washing the face, avoid scrubs, cleansing brushes, or excessive rubbing. Choose gentle cleansing products that do not leave the skin feeling overly dry after washing.

  3. Choose hydrating and soothing ingredients
    Ingredients such as hyaluronic acid, panthenol, ceramides, aloe vera, beta-glucan, peptides, or gentle botanical extracts can be considered to help the skin maintain hydration and comfort.

  4. Simplify the skincare routine
    When the skin is unstable, it is not recommended to layer too many serums, acids, or high-concentration active products at the same time. Start with toner, cream, and a hydrating mask for basic care.

  5. Adjust frequency according to skin condition
    Everyone’s skin tolerance is different. If obvious stinging, redness, or discomfort occurs after use, reduce frequency or pause use and observe the skin condition.


How to build a 3-step routine for delicate skin?

Delicate skin can still be cared for, but it needs a gentler and more rhythmic approach. When the skin feels dry, tight, or uncomfortable, you can build a daily skincare routine around three directions: mist as a base, cream for moisture, and mask for extra hydration.

Step 1: Relief Moisturizing Spray|Refreshing hydration + base conditioning

When the skin condition is not ideal and easily feels dry or tight, a gentle mist-type toner can be used as the first step of skincare. It helps replenish moisture and maintain a fresh, comfortable skin feel.

Ingredient features:

  • Botanical soothing complex, reed and poria complex, and kava pepper: Help the skin maintain comfort and reduce discomfort caused by external environmental factors.

  • Soothing tetrapeptide, beta-glucan, and aloe vera: Commonly used in hydrating and soothing skincare products to help the skin maintain a soft and hydrated feel.

  • Malachite extract and Pro-Vitamin B5: Help the skin maintain a balanced-looking condition and are suitable for daily skincare use.

How to use:

Use every morning and evening after cleansing. Spray onto the face, neck, or areas that easily feel dry or uncomfortable. It may also be used for short-time wet compress according to skin condition as a basic hydrating and soothing step.

Step 2: Ultra Soothing Sensitive Skin Cream|Gentle moisture + maintaining a protective feel

When the skin feels unstable, dry, or more affected by external environmental factors, a cream can provide proper moisture and help the skin maintain a soft and comfortable feel.

Ingredient features:

  • Soothing tetrapeptide and soothing hexapeptide: Help the skin maintain comfort and make the skin feel smoother.

  • Ceramide III, cholesterol, sphingolipids, and lecithin: Commonly used in moisturizing and nourishing formulas to help the skin maintain a moisturized and soft feel.

  • Bisabolol, aloe vera, and kava extract: Botanical and soothing ingredients suitable for daily skincare when the skin feels dry or uncomfortable.

How to use:

Use every morning and evening after toner. Apply an appropriate amount evenly to the face and neck. If certain areas feel especially dry, apply a thin extra layer as needed and avoid excessive rubbing.

Step 3: Instant Soothing & Moisturizing Mask|Intensive hydration + soothing comfort

When the skin feels especially dry, tight, or unstable, Instant Soothing & Moisturizing Mask can be used as an extra hydrating care step to help the skin maintain moisture, softness, and comfort.

Ingredient features:

  • Soothing tetrapeptide: Helps the skin maintain comfort.

  • Hyaluronic acid and beta-glucan: Hydrating ingredients that help the skin maintain a moisturized and soft feel.

  • Licorice, green tea, and chamomile extracts: Botanical ingredients commonly used in soothing skincare products, suitable during dryness or seasonal changes.

  • Reishi, grape seed, seaweed, and soybean extracts: Multiple botanical ingredients that help the skin maintain a healthy-looking glow and balanced appearance.

How to use:

Use 2–3 times per week when the skin feels dry, during seasonal changes, or when the skin condition feels less stable. After use, follow with cream according to skin condition to help maintain moisture.

Yes. Vitamin B3 is commonly used in oil-water balance and refreshing skincare routines. Oily skin can choose a lightweight serum as part of daily care.
