4 × 20 ml dropper bottle. Total net content: 80 ml.

4K Plus 5X Hyaluronic Facial Serum is a 20 ml dropper serum for a lightweight hydrating layer before facial cream. It is designed for skin that feels dehydrated or looks less plump when dry.

Formula and function

  • Hyaluronic acid is the ingredient highlighted by this reference. It is a humectant: it binds water at the skin surface, helping the skin feel more supple.
  • The serum format spreads in a thin layer without the coverage of a BB cream or the richer finish of a night cream. Follow with moisturiser to complete the routine.
  • No molecular weight, number of hyaluronic-acid forms or finished-product percentage is specified here. “5X” identifies the range and is not a concentration statement.

Choosing this reference

A hydration-focused layer for use morning or evening. It is a leave-on product and does not replace a moisturiser or sunscreen.

How to use

  1. After cleansing and toner, apply a small amount to clean, slightly damp skin. Two or three drops can be used as a starting amount; adjust to coverage.
  2. Press or spread gently over face and neck, avoiding the eyes. Avoid touching the dropper directly to the skin.
  3. Follow with moisturiser. Use sunscreen as the final morning skincare step, then replace the serum cap tightly.

Care and precautions

For external use only. Test on a small area before first use, particularly with reactive skin. Avoid eyes and broken or irritated skin. Stop if irritation develops. Keep the container closed, away from excessive heat, direct sunlight and children. The original package gives the complete ingredients for your batch.
