Description

DR.ALTHEA 345 Relief Serum is a daily calming serum for sensitive, acne-prone skin. It targets redness, dryness, and a weakened skin barrier in one simple step. The lightweight formula absorbs fast, so skin never feels sticky or heavy. An advanced multi-layer delivery system carries the actives in evenly. Birch sap and tea tree leaf water ease visible redness. Niacinamide, panthenol, and PDRN work together to hydrate and comfort skin. Ceramide NP reinforces your skin's natural barrier. With regular use, skin can look smoother, calmer, and more balanced. The look of post-blemish marks and uneven texture may fade too. This serum is non-comedogenic and sensitive skin tested, so it suits daily wear. Apply morning and night after cleansing and toner, then follow with moisturiser.

What This Serum Does for Your Skin

DR.ALTHEA 345 Relief Serum is a daily serum built for reactive skin. It addresses three things at once: irritation, dryness, and a weakened skin barrier.

The texture is lightweight and fast absorbing. It sinks in within seconds and never leaves a sticky or heavy finish. An advanced multi-layer delivery system carries the active ingredients where skin needs them most. The milky, watery gel spreads easily across the face without pilling or dragging. Richer actives sit inside lighter carriers, so skin takes them in without a greasy finish.

This serum is non-comedogenic and sensitive skin tested. That makes it a steady daily pick for skin that reacts easily to new products. Redness and tightness are common triggers for reaching for a calming serum. Post-blemish marks are another. This formula was built around exactly those concerns.

Morning and night, it acts as a consistent baseline step. Skin gets even comfort and moisture without extra fuss.

The Key Ingredients Inside

Birch sap, listed as Betula Platyphylla Japonica Juice, sits near the top of the ingredient list. It replenishes lost moisture, leaving skin less tight and dry.

Tea tree leaf water brings a gentle calming effect. It eases visible redness without any harsh, drying sensation.

Niacinamide targets an uneven-looking complexion. With regular application, skin can appear less blotchy and more balanced.

Panthenol, also called provitamin B5, softens the skin surface. It settles a sense of comfort within minutes.

PDRN, listed as Sodium DNA, targets the skin barrier directly. Skin that has felt compromised or reactive can start to look steadier over time.

Ceramide NP locks moisture into the skin. It reinforces the barrier that keeps water in. Irritants stay out, and skin grows less prone to flare-ups.

Centella asiatica and madecassoside round out the formula. Both are known for keeping reactive skin quiet and soft. Together, these ingredients target redness, dryness, and barrier weakness from a few different angles.

How Your Skin Responds Over Time

Right after application, skin should seem more settled and less tight. The lightweight texture stays comfortable even when worn under other products.

Over the following weeks, many people notice their skin turning smoother and less reactive. Redness often moves toward a quieter baseline. Skin that has felt easily irritated by richer products may find this formula easier to tolerate.

The appearance of post-blemish marks and uneven texture may also improve with continued care. Barrier support plays a part here: a stronger barrier lets skin recover more evenly after a blemish.

Results appear gradually rather than overnight. Everyone's skin responds at its own pace, so results can vary from one person to the next. Skincare works best as a routine, not a single application, so consistency matters more than speed. Many people describe the daily routine as simple rather than demanding, since one step covers several needs at once.

The formula is non-comedogenic and sensitive skin tested, so it works well for everyday wear without disrupting your skin's rhythm.

How to Layer It in Your Routine

Apply this serum after cleansing and toner, while skin is still slightly damp. This lets the lightweight formula sink in more easily.

Smooth an appropriate amount across your face and pat gently until fully absorbed. Patting rather than rubbing keeps active ingredients in place without pulling or tugging.

Follow with a moisturiser to seal in the hydration this serum provides. A barrier-friendly cream pairs well, especially for skin that runs dry or sensitive.

A hydrating toner beforehand can prepare skin to take in the serum's actives. A ceramide-rich moisturiser afterward helps lock in the results.

Fit this step into your morning and night routine as a twice-daily habit. Consistency carries skin toward a more even, resilient baseline over time. It fits neatly into a short routine for anyone who prefers fewer, simpler steps.

If exfoliants or retinoids feature in your routine, apply this serum afterwards for extra barrier care.

Who This Serum Is For

This serum suits anyone with sensitive or acne-prone skin who wants a balanced, more comfortable complexion. If redness, tightness, or reactivity are familiar frustrations, this formula was shaped with your skin in mind.

It also suits anyone recovering from a breakout who wants extra barrier support. The lightweight, fast texture means it slots into any routine without sitting heavy. First-time K-beauty users often appreciate how few steps this serum asks for.

Skin that flares up after trying new products can often manage this formula without extra irritation. This serum is non-comedogenic and sensitive skin tested, making it a gentle choice for reactive skin.

If your skin has been irritated, dry, or uneven lately, relief can start with one simple step. Bring DR.ALTHEA 345 Relief Serum into your routine, morning and night. Give your skin the soothing care it deserves.

How to Use

1. After cleansing and toning, apply an appropriate amount of serum to your face. 2. Gently pat until fully absorbed, working from the centre of your face outward. 3. Follow with a moisturiser to seal in the hydration. 4. Use morning and night as a steady daily step. This serum sits early in your routine, right after toner and before heavier creams. A hydrating toner beforehand and a ceramide-rich moisturiser afterward both pair well with this formula. If exfoliants or retinoids feature in your routine, apply this serum afterwards to give your skin barrier extra support.

Birch sap · tea tree leaf water · ceramide NP

A daily calm for skin that reacts to everything.

345 Relief Serum takes on irritation, dryness and a weakened barrier in one lightweight step. Non-comedogenic and sensitive-skin tested, so it holds up as an everyday baseline rather than an occasional rescue.

What does it do?

Three problems, one step.

Redness, tightness and post-blemish marks are the concerns this was built around.

Redness, eased

Barrier, reinforced

PDRN, listed as sodium DNA, targets the barrier directly, and ceramide NP locks moisture in so skin grows less prone to flaring.

Tone, more even

Niacinamide works on a blotchy-looking complexion, with panthenol softening the surface within minutes of application.

What's in it?

Carried in evenly.

An advanced multi-layer delivery system puts richer actives inside lighter carriers.
