Calm irritation and strengthen your skin barrier with Dr.Althea 345 Relief Serum, formulated with Birch Sap, PDRN, Centella Asiatica, and Ceramide NP. Shop authentic K-beauty at Seoulma Skincare.

For skin that's easily irritated, post-breakout, or simply overwhelmed by too many actives, the Dr.Althea 345 Relief Serum is the reset button your routine has been missing. This daily soothing serum is built to do three things in one lightweight step: calm visible irritation, deliver deep hydration, and reinforce a compromised skin barrier — making it a staple for sensitive, reactive, and acne-prone skin types alike.

At its core is a multi-layered Centella Asiatica (Cica) technology, combining Centella leaf water, Centella extract, and isolated Madecassoside for compounded soothing power, alongside barrier-supporting Ceramide NP to help skin hold onto moisture and resist future irritation. The formula is rounded out with Birch Sap and a 3D Hyal-TECA complex — a blend of multiple hyaluronic acid weights paired with TECA — for hydration that reaches both the surface and deeper layers of skin, along with Niacinamide to support a clearer, more even-looking tone and PDRN to aid the skin's natural recovery process. Tea Tree Leaf Water adds an extra layer of blemish-focused care, rounding out this deceptively simple, thoughtfully constructed formula.

The result is a fast-absorbing, silky-textured serum that layers invisibly under moisturizer, sinks in without stickiness or residue, and is non-comedogenic and sensitive-skin tested — free from artificial colors and fragrance, so it won't add fuel to already-inflamed skin.

Key Benefits

  • Calms Visible Irritation — Multi-layered Centella Asiatica technology soothes redness and discomfort
  • Strengthens the Skin Barrier — Ceramide NP helps rebuild and protect compromised skin
  • Deep, Lasting Hydration — 3D Hyal-TECA complex hydrates at multiple skin layers without feeling heavy
  • Supports Post-Blemish Recovery — PDRN and Tea Tree Leaf Water aid recovery and help fade the look of post-acne marks
  • Gentle Enough for Daily Use — Non-comedogenic, fragrance-free, and sensitive-skin tested
  • Lightweight, Non-Sticky Finish — Fast-absorbing texture that layers effortlessly under the rest of your routine

How to Use

Apply a small amount to clean, freshly toned skin, morning and night, before your moisturizer. For an extra soothing boost, pair it with the Dr.Althea 345 Relief Cream as your final step.


Why We Recommend It

We recommend this serum specifically for customers whose skin has been through it lately — post-breakout, post-active-overload, or just chronically reactive. It's one of the few serums we carry that treats "sensitive skin" as a barrier problem to solve rather than a limitation to work around: instead of stripping the routine down to almost nothing, it actively rebuilds the barrier while still delivering real hydration and mild blemish support. It's also a smart layering piece — gentle enough to sit underneath stronger actives (like your Dr. Melaxin TX line or Sungboon Editor ampoules) on days your skin needs a buffer, but effective enough to stand alone on its own on bad-skin days.

Dr.Althea 345 Relief Serum: FAQ

Dr.Althea · 30 ml

What is the Dr.Althea 345 Relief Serum?
A lightweight, fast-absorbing gel-cream serum from the Korean brand Dr.Althea. It is designed to calm visible irritation, hydrate and support the skin barrier in one simple step, without a sticky finish.
What are the key ingredients?
The key actives are birch sap, tea tree leaf water, panthenol, niacinamide, PDRN and ceramide NP. Together they hydrate, calm redness and support a stronger skin barrier over time. For the full ingredient list (INCI), please check the packaging of your product.
Who is it for?
It suits all skin types and is especially made for sensitive, easily irritated and blemish-prone skin, as well as skin with post-blemish marks and uneven tone.
How do I use it?
After cleansing and toning, lightly shake the bottle and apply 2 to 3 drops to your face. Gently pat it in for better absorption. It is a daily serum, so you can use it morning and evening.
Where does it fit in my routine, and can I pair it with the 345 Relief Cream?
Apply it after toner and before your moisturizer. It works nicely with the Dr. Althea 345 Relief Cream: the serum for lightweight hydration and calming, the cream to seal it in. In the morning, finish with sunscreen.
Can I wear it under makeup?
Yes. It is fast-absorbing and non-sticky, which makes it a good prep step. Use a few drops, pat it in and wait a minute or two before moisturizer and base so the layers don’t pill.
Will it clog my pores?
The serum is described as non-comedogenic and is formulated with blemish-prone skin in mind. Every skin is different, so introduce it gradually and patch test first if your skin is very reactive.
Can I use it with retinol, vitamin C or acids?
Yes, many people use a soothing serum like this alongside actives. Introduce one new active at a time and layer the calming serum and a moisturizer around it. If your skin feels irritated, pause your strong actives and let the barrier recover.
Does it treat acne or post-blemish marks?
It is a calming, barrier-supporting serum, not a medicated acne treatment. It helps soothe visible redness, and the niacinamide helps visibly improve post-blemish marks and uneven tone with regular use over several weeks. Results vary. For persistent or severe acne, please see a dermatologist.
Are there any allergy considerations?
If you are sensitive to tea tree, or have allergies to fish (PDRN is commonly derived from salmon), please check the ingredient list on the packaging before use. For external use only, avoid contact with the eyes, and stop using the product if irritation occurs.
