DearKlairs Blue Youth Activating Drop Serum EGF & FGF 1.69 fl oz — 10ppm Growth Factors, Soothing Barrier Repair

This water-light drop concentrates two growth factors at Korea's permitted top concentration to support the skin’s natural renewal processes without heavy textures or fragrances. Formulated for sensitive and reactive skin, it combines EGF and FGF with a natural guaiazulene calming complex that gives the formula its signature blue tint. Clinically tested for quick soothing and non-comedogenic performance, the serum works as a first-step treatment after cleansing to prepare skin for the rest of your routine.

How does this serum address post-blemish marks and texture?

The formula uses epidermal growth factor (EGF) at 10ppm to encourage the skin’s renewal cadence, helping marks look less noticeable over time. Consumer results show visible improvement in post-blemish appearance within weeks when used consistently as directed.

• 10ppm EGF concentration — maximum allowed in Korea for topical peptides
• Combined FGF supports smoother skin surface and texture
• Daily application as first step speeds visible outcomes in consumer testing

Will this serum be gentle enough for sensitive or acne-prone skin?

Yes — the formulation is lightweight, fragrance-free, and clinically tested to be non-comedogenic, making it suitable for oily, combination, acne-prone, and reactive skin. Dermatologist testing also showed quick reduction in visible irritation, so it can be used when skin is easily triggered by stronger actives.

• Water-light drop texture absorbs in seconds without sticky residue
• Proven non-comedogenic — compatible with acne-prone skin
• Contains natural guaiazulene to visibly soothe redness without artificial color

How should I use the Blue Youth Activating Drop in my routine?

Apply as the very first step on clean, bare skin so the growth factors contact the skin directly. Use 3–4 drops and gently pat until absorbed, then follow with toner, moisturizer, sunscreen in the morning, or treatment creams at night.

• Use after cleansing; apply 3–4 drops to face and neck
• Pat lightly to aid absorption before layering other products
• Compatible with morning and evening routines; always follow with SPF during daytime

What are the notable ingredients and immediate benefits?

• EGF & FGF at 10ppm each to support renewal and fine-line appearance
• 1,000ppm guaiazulene for visible soothing of redness and irritation
