DearKlairs Blue Youth Activating Drop EGF + FGF Serum — Blue 1.69 fl oz, Calming Barrier Repair

DearKlairs Blue Youth Activating Drop is a lightweight, blue-hued serum formulated with 10ppm EGF and 10ppm FGF to support post-blemish mark recovery and comfort reactive skin.

This water-light serum combines epidermal and fibroblast growth factors with a concentrated guaiazulene calming complex to soothe visible irritation, help refine texture, and reduce the appearance of post-acne marks. Designed for sensitive and easily reactive skin, the formula absorbs quickly without residue and layers smoothly under other skincare steps. Clinical and consumer testing backed the product’s calming and non-comedogenic profile, making it suitable for daily morning or evening use.

How does this serum target post-blemish marks?

The formula delivers EGF at the Korean regulatory maximum of 10ppm alongside 10ppm FGF to support the skin’s natural renewal processes. In a consumer study, marks showed measurable improvement with consistent daily application over several weeks.

• Contains 10ppm EGF and 10ppm FGF to support cell renewal.
• Consumer study: visible mark reduction at two and four weeks.
• Recommended application: 3–4 drops on clean skin before other products.

Will this work for sensitive or acne-prone skin?

Yes — the serum was designed to be lightweight and non-irritating; dermatological testing showed rapid visible reduction in irritation and a non-comedogenic result. Its gentle profile means it can be used by oily, combination, acne-prone, and reactive skin without heavy residue.

• Dermatologist-tested for reduced irritation in minutes.
• Proven non-comedogenic so it won’t clog pores.
• Fast-absorbing, water-light texture ideal for layering.

What gives the serum its signature blue color and calming effect?

The blue tint comes from a concentrated guaiazulene complex included at 1,000ppm, a botanical-derived ingredient renowned for soothing visible redness. The calming extract is free from artificial dyes and fragrance, so the color is inherent to the active ingredient rather than added pigments.

• 1,000ppm guaiazulene provides visible calming benefits.
• No artificial colorants or fragrance added.
• Melts into skin for immediate soothing without stickiness.

How should I incorporate this into my routine?

Use the serum as the first step after cleansing on bare skin to maximize absorption of growth factors. Pat 3–4 drops gently into the face, then follow with toner, moisturizer, and any actives you normally use. Suitable for twice-daily use if your routine and skin tolerance allow.

• Apply 3–4 drops to clean, dry skin as the first step.
• Pat gently until absorbed before layering other products.
• Can be used morning and evening as tolerated.

Who is this for: This serum is for people seeking a gentle, science-backed option to help fade post-blemish marks and calm redness without heavy textures or strong fragrances. It suits sensitive, acne-prone, oily, or combination skin types who want to add targeted growth factors (EGF and FGF) to their daily routine and who prefer fast-absorbing, non-greasy products. Ideal for anyone wanting a soothing, layerable serum that supports visible recovery while playing nicely with other skincare steps.
