Dr.Althea 345 Relief Serum - Daily Hydrating Face Serum 1.01 fl oz, Soothes Redness & Strengthens Barrier

Dr.Althea 345 Relief Serum is a lightweight, non-comedogenic daily face serum that soothes redness, restores hydration, and supports a healthier skin barrier.

This Korean vegan serum combines targeted calming agents, barrier-repair lipids, and hydration boosters to help dry, irritated, or post-acne skin feel calm and balanced. It layers easily under creams and makeup, absorbs without stickiness, and avoids artificial fragrances, parabens, and colorants. The formula is designed to address multiple sensitivity triggers—redness, oil imbalance, and weakened barrier—without clogging pores.

How does this serum reduce redness and irritation?

The serum contains plant-based actives like Centella PDRN and Tea Tree Leaf Water that soothe stressed skin while antioxidant Resveratrol helps calm visible inflammation. Niacinamide works in tandem to even skin tone and control sebum, so flare-ups can appear less frequent and pronounced.

• Centella PDRN delivers nourishment to reinforce the skin’s natural defenses.
• Resveratrol provides antioxidant support to calm redness-prone areas.
• Tea Tree Leaf Water soothes and helps balance excess oil gently.
• Niacinamide evens tone and helps manage oil production.

Will this serum hydrate dry or sensitized skin without feeling greasy?

Yes — Rice PDRN (Sodium DNA) and Ceramide NP supply deep, long-lasting moisture while strengthening the barrier, yet the formula remains lightweight and non-sticky. The result is nourished skin that doesn’t feel heavy, making it suitable for layering under other products.

• Rice PDRN targets deep hydration and barrier reinforcement.
• Ceramide NP helps lock in moisture and refine texture.
• Non-comedogenic base avoids pore-clogging while hydrating.
• Light texture allows comfortable daytime and nighttime use.

Can I use this serum if I’m concerned about breakouts or clogged pores?

The formula is certified non-comedogenic and includes sebum-regulating Niacinamide plus clarifying Tea Tree Leaf Water to help keep pores clear. It’s formulated to provide the hydration and barrier care that can prevent compensatory oil production that often contributes to breakouts.

• Non-comedogenic certification reduces risk of pore congestion.
• Niacinamide helps control excess oil that can cause clogs.
• Tea Tree Leaf Water supports a balanced, cleaner complexion.
• Lightweight application layers well under acne-focused treatments.

How should I include this serum in my daily skincare routine?

Apply the serum after cleansing and toning, while skin is slightly damp, to maximize absorption. Follow with a moisturizer and daily SPF in the morning or a nourishing cream at night for best barrier support.

• Use morning and/or evening on clean, damp skin for best results.
• Layer under moisturizer and sunscreen in daytime routines.
• Can be combined with targeted treatments as tolerated by skin.
• One 1.01 fl oz bottle supports regular daily use for several weeks.

It’s also a good pick for shoppers seeking a cruelty-free, vegan-certified Korean skincare option free from artificial fragrance, colorants, and parabens. If you need a calming daily serum that layers under makeup and complements both morning and evening regimens, this product can fit into your routine.
