DearKlairs Blue Youth Activating Drop EGF & FGF Serum 0.67 oz — 10ppm Each, Calming Azulene for Sensitive Skin

DearKlairs Blue Youth Activating Drop is a lightweight serum that combines 10ppm EGF and 10ppm FGF with a calming azulene complex to help soothe reactive skin and support the appearance of post-blemish marks and texture.

This water-light formula is built for sensitive, acne-prone, and combination skin that needs gentle yet targeted support. It layers easily under your routine, absorbs quickly without tackiness, and uses clinically-backed concentrations of growth factors permitted in Korea. The signature blue hue comes from natural guaiazulene rather than synthetic dyes or fragrance, creating a calming sensory experience while you treat visible irritation and unevenness.

How does this serum help with post-blemish marks and skin texture?

The serum delivers EGF and FGF peptides at the maximum allowed concentration in Korea to support the skin’s renewal processes. Regular use aims to improve the look of post-blemish marks and refine surface texture without introducing harsh actives that can irritate sensitive skin.

• Contains 10ppm EGF and 10ppm FGF—formulated to aid visible renewal.
• Consumer results show measurable improvement in marks over weeks.
• Light texture helps active ingredients penetrate without layering heaviness.

Will this serum irritate sensitive or acne-prone skin?

DearKlairs positioned this drop for reactive skin types: the formula was dermatologist-tested and designed to be non-comedogenic, minimizing pore clogging and surface irritation. The natural azulene complex soothes visible redness, making it appropriate for users who need calming support alongside active repair ingredients.

• Clinically tested for reduced visible irritation in short-term assessments.
• Non-comedogenic—formulated with acne-prone skin in mind.
• No artificial fragrance or synthetic dyes; gentle calming actives included.

How should I incorporate this serum into my daily routine?

Use the Blue Youth Activating Drop right after cleansing on bare skin, before toner, moisturizer, and heavier treatments. A few drops are enough; pat gently until absorbed, and then continue with the rest of your regimen. It’s suitable for morning or evening use and pairs well with hydrating and barrier-supporting products.

• Apply 3–4 drops onto clean, dry skin as the first step after cleansing.
• Pat in gently; wait a few seconds before layering toner or moisturizer.
• Compatible with most routines—avoid mixing with very strong exfoliating acids at once if skin is reactive.

What are the key ingredients and sensory details?

EGF and FGF peptides are the feature actives, each at 10ppm, supported by 1,000ppm guaiazulene for visible calming effects and the product’s natural blue tone. The serum’s thin, fast-absorbing texture leaves no sticky residue, making it discreet under sunscreen or makeup. The ingredient selection emphasizes soothing and recovery rather than aggressive resurfacing.

• 10ppm EGF + 10ppm FGF to support visible renewal and texture improvement.
• 1,000ppm guaiazulene for redness-soothing and natural blue color.
• Water-light, non-sticky drop texture absorbs within seconds.

Who is this for? If you have sensitive, reactive, acne-prone, oily, or combination skin and want a gentle peptide serum that supports the look of post-blemish marks, refines texture, and calms redness without heavy layers or fragrance, this product is designed for you. It’s also a good choice for people who prefer clinically informed concentrations and a fast-absorbing feel that fits into both morning and evening routines.
