DearKlairs Blue Youth Activating Drop — EGF + FGF Serum 10ppm Each, Soothing & Repairing for Sensitive Skin

DearKlairs Blue Youth Activating Drop is a lightweight EGF + FGF serum formulated to soothe irritation, support post-blemish recovery, and hydrate sensitive skin without heaviness.

This water-light drop brings together epidermal and fibroblast growth factors at Korea's permitted maximum (10 ppm each) to assist skin renewal while staying gentle enough for reactive or acne-prone complexions. Its calming blue tint comes from 1,000 ppm guaiazulene — a naturally derived anti-irritant — and the formula is free of artificial fragrance and coloring. Clinical and consumer testing show visible reductions in irritation and improvement in post-blemish marks with regular use, and the non-comedogenic texture absorbs quickly, making it easy to layer into morning or evening routines.

How will this serum help post-blemish marks?

The serum contains EGF at 10 ppm — the highest concentration allowed in Korea — which supports the skin's natural surface renewal process. In a consumer study, users reported measurable improvement in post-blemish marks after consistent daily application for two and four weeks. Use it as an early step in your routine so the growth factors make direct contact with clean skin.

• 10 ppm EGF and 10 ppm FGF to aid cell renewal
• Consumer-study improvement: ~14.75% at two weeks, ~23.21% at four weeks
• Apply 3–4 drops onto bare skin after cleansing for best absorption

Is this suitable for sensitive or acne-prone skin?

Yes — the formula was developed with reactive skin in mind and tested by dermatologists. It’s non-comedogenic and designed to reduce visible irritation quickly, so it won’t leave pore-clogging residue or heavy film. The calming complex helps diffuse redness without adding potentially irritating fragrances or harsh actives.

• Dermatologist-tested and proven non-comedogenic
• Visible irritation reduction noted in clinical testing within minutes
• No artificial fragrance or colors; lightweight, fast-absorbing texture

What makes the blue color and calming effect unique?

The serum’s signature blue comes from guaiazulene at 1,000 ppm, a naturally sourced ingredient known for its soothing profile. It helps visibly calm redness and complements the growth-factor blend, creating a formula that targets both sensitivity and surface-level discoloration. The blue hue is functional, not decorative.

• 1,000 ppm guaiazulene for visible calming and anti-irritant benefits
• Color is from active botanical ingredient, not artificial dyes
• Harmonizes with EGF/FGF to improve overall skin appearance

How do I use this serum in my routine?

Use the Blue Youth Activating Drop immediately after cleansing while skin is bare so the growth factors can penetrate effectively. A few drops provide enough coverage for the entire face; pat gently until absorbed, then follow with toner, moisturizer, and sunscreen if used in the morning. Because it’s lightweight and fast-absorbing, it layers well under oils, creams, and actives.

• Dispense 3–4 drops onto clean, dry skin as the first step after cleansing
• Gently pat to absorb; follow with toner, moisturizer, and SPF for daytime
• Suitable for daily morning or evening use as part of a multi-step routine

This serum is intended for people who want a gentle, science-backed approach to improving post-blemish marks, restoring barrier comfort, and soothing visible redness without heavy textures or fragrances. It fits well for sensitive, oily, combination, and acne-prone skin types, and for anyone who prefers a fast-absorbing serum that can be layered under other treatments. If you’re looking for a non-irritating growth-factor product to add early in your routine, DearKlairs Blue Youth Activating Drop is formulated to meet that need.
