EGF Blue Youth Activating Drop: the blue first step
The Blue Line hero in one page: what it is, where it goes in a routine, sizes and MSRP, and the one published result you can quote.
If you carry one Dear, Klairs product, this is the one clients are most likely to ask for by name. The EGF Blue Youth Activating Drop is a lightweight, watery first serum. It goes on right after cleansing, before toner and the rest of the routine. The blue color is the first thing people notice, and it gives your staff an easy opening line.
What it is
The Drop belongs to the Blue Line, which Dear, Klairs positions around irritation relief and barrier care, built on guaiazulene. The formula combines:
- EGF at 10 ppm, listed on the label as sh-Oligopeptide-1.
- FGF at 10 ppm, listed as sh-Polypeptide-1.
- Guaiazulene at 1,000 ppm, a naturally derived blue compound best known from chamomile. It gives the serum its color.
- Adenosine, in a formula at pH 5.5.
The texture is thin, fast-absorbing and non-sticky. The product description frames it for sensitive-feeling skin routines focused on early firmness care, the look of post-blemish marks and visibly stressed skin. It has no fragrance or essential oils listed, so you can describe it as having no added fragrance.
Who it suits
- Clients who want a thin serum step with no heavy or oily feel.
- Clients whose skin feels easily stressed and who want one simple added step.
- Clients focused on post-blemish marks.
- Clients starting to think about the look of firmness who prefer a light texture.
How it is used
Cleanse, apply a few drops, let them absorb, then continue with toner, other serums and moisturizer. In the morning, finish with an SPF. Because the Drop comes first, it is easy to add to a routine a client already has. Nothing else needs to change.
What you can quote
There is one published result for the Drop. Say it this way: post-blemish marks improved 23.21% after 4 weeks in a study of 20 adults (ProbeM Skin Research Center). The 2-week figure is +14.75%.
The Drop is tested for primary irritation on sensitive skin and for non-comedogenicity. Its visible calming claim is visibly calmer-looking skin in about three minutes. Recognition you can mention: 2026 Seoul Awards Beauty Winner and Soko Glam Best of K-Beauty 2024. The brand reports 1M+ units distributed as of April 2026 (brand-reported).
Sizes and MSRP
- 50 mL, $39.99 MSRP
- 10 mL, $12.99 MSRP
The 10 mL is a low-risk first purchase for a curious client. The 50 mL is the size to face at eye level.
A note on color: guaiazulene is naturally derived, so the blue can vary slightly from batch to batch without affecting quality. Tell your staff before a new case arrives so no one is caught off guard.
At the counter: "This is the first step after cleansing, before toner. The blue comes from guaiazulene, and it has no added fragrance."
