DearKlairs Blue Youth Activating Drop Serum — EGF & FGF 10ppm, Soothing Barrier Repair (1.69 oz)

DearKlairs Blue Youth Activating Drop is a lightweight daily serum that uses clinically tested EGF and FGF at 10ppm each to support post-blemish recovery, soothe redness, and strengthen sensitive skin’s barrier.

This water-light Korean serum combines epidermal and fibroblast growth factors with a natural guaiazulene calming complex to target post-blemish marks, improve texture and reduce visible irritation without harsh actives or artificial fragrance. Formulated for reactive, acne-prone and combination skin, the formula absorbs quickly with no sticky residue, making it easy to layer under moisturizer and SPF morning or night. Clinical testing demonstrates measurable improvements in redness and post-blemish appearance within weeks when used consistently.

How quickly will I see results on post-blemish marks?

Visible improvement depends on skin type and consistency, but consumer data shows measurable changes within two to four weeks. For best results, use daily as instructed and pair with sunscreen during the day to protect new skin.

• Contains EGF peptide at 10ppm—the maximum allowed concentration in Korea—for renewal support.
• Consumer study: ~14.8% visible improvement at two weeks, ~23.2% at four weeks.
• Use morning and night after cleansing and before moisturizer for steady results.

Will this serum irritate sensitive or acne-prone skin?

The formula is developed specifically for sensitive and reactive skin: dermatologist-tested, non-comedogenic, and free from artificial fragrance. It relies on growth factors and a natural blue calming complex rather than harsh exfoliants or fragrances that can trigger flare-ups.

• Dermatologist-tested to reduce visible irritation quickly—clinical data shows significant short-term reduction.
• Non-comedogenic, suitable for oily, acne-prone and combination skin types.
• Contains guaiazulene (1,000ppm) for natural calming and the serum’s signature blue tone.

How should I incorporate this drop into my routine?

Apply as the first step after cleansing on bare skin so the active peptides can absorb efficiently. Follow with toner if you use one, then your moisturizer, oil, and daytime SPF as needed.

• Dispense 3–4 drops onto cleansed skin and pat gently to help absorption.
• Use morning and/or evening; layer other actives afterward if your skin tolerates them.
• During daytime, follow with broad-spectrum sunscreen to protect recovering skin.

Can this serum help with fine lines and skin texture?

EGF and FGF support the skin’s natural recovery processes, which can improve the look of fine lines and overall texture over time without the irritation risk of stronger anti-aging ingredients. Results are gradual and best when combined with consistent sun protection and a gentle routine.

• Growth factors encourage cellular processes linked to smoother texture and softer fine lines.
• Lightweight, fast-absorbing texture makes it simple to include alongside other gentle actives.
• Designed for sensitive or reactive skin that may not tolerate retinoids or acids.

Who is this for: DearKlairs Blue Youth Activating Drop is ideal for people with sensitive, reactive, acne-prone, or combination skin who want a gentle, peptide-forward approach to fading post-blemish marks, calming redness, and supporting a healthier skin barrier. It’s suitable for those avoiding strong exfoliants or fragrances and for anyone seeking a fast-absorbing, non-sticky serum that layers easily into both morning and evening routines.
