Since 2010, Dear, Klairs has made minimal, gentle skincare that helps sensitive skin find its balance, instead of trying to change it.
Units distributed worldwide, as reported by Dear, Klairs.
Closer to water than to a serum. It absorbs in seconds, so it goes on first, right after cleansing.
The blue comes from guaiazulene, a naturally derived compound best known from chamomile. No colorant is added, so the shade can shift slightly from batch to batch without any change in quality.
Signal peptide at the heart of the formula. Supports the look of firm, resilient skin.
Second growth-factor peptide paired with EGF for density and bounce.
Naturally derived blue compound. Comforts skin that looks flushed.
Well-studied firming ingredient that rounds out the peptide pair.
Only results Dear, Klairs has published. Tested seven ways, from sensitive-skin irritation to post-blemish marks.
Post-blemish result: ProbeM Skin Research Center, Dec 2025–Jan 2026, 20 participants aged 20–40, as shown on klairs.com. Individual results vary.
From stressed to visibly calmer in about three minutes, straight after cleansing.

Dear, Klairs joined the pop-up hosted by skincare creator Song of Skin. Shoppers queued, filmed the shelf and left with EGF samples.
The Blue EGF “EGF Maxxing” pop-up at Hapa Kristin Melrose ran four days: two creator previews, then a public weekend that drew lines on both days, including a rainy Sunday.
