In the ever-evolving world of skincare, COSRX remains a consistent favorite – and for good reason. This K-beauty brand continues to deliver results-driven products that elevate your routine without overwhelming your skin. Today, I’m diving into two of their standout products: the new COSRX Ceramide Skin Barrier Moisturizer and the COSRX 6 Peptide Skin Booster. Whether you’re dealing with a compromised skin barrier or looking to rejuvenate tired, dull skin, these two could be your next skincare essentials.
1. NEW COSRX The Ceramide Skin Barrier Moisturizer
Nourishment. Protection. Resilience.
This latest launch from COSRX is a skin savior – especially for those with sensitive, dry, or barrier-compromised complexions. The Ceramide Skin Barrier Moisturizer is a highly concentrated ceramide moisturizer that locks in hydration, soothes the skin, and replenishes the moisture barrier.
Packaging:
I don’t know why but I really love beauty products with high quality packaging when tube is inside the box. And I really love matte tubes! And the tube has protector.
Key Ingredients:
- 5 Types of Ceramides (NP, NS, AS, EOP, AP) – Rebuild and reinforce your skin’s natural barrier.
- Panthenol (Vitamin B5) – Intensely hydrates and soothes.
- Allantoin & Betaine – Reduce irritation and calm stressed skin.
- 5 multi-functional Hyaluronic Acid.
Texture & Feel:
This moisturizer is all about that soft, comforting feel with a silky, gliding texture. It melts into the skin effortlessly, gliding over the cheeks or jawline with no tugging. Despite its rich hydration, it’s never heavy or oily – and here’s the kicker: it delivers moisture that lasts up to 200 hours! Watch my honest video review!
Recommended for:
COSRX The Ceramide Skin Barrier Moisturizer is suitable for all skin types, delivering deep hydration and barrier support for healthy, balanced skin while soothing sensitive, dry, or damaged skin.
Best for:
Dry, dehydrated, sensitive, and irritated skin types; perfect after exfoliation, retinoids, or harsh weather exposure.
My experience:
My skin immediately felt hydrated without greasy feeling. With nightly use, the barrier repair benefits were more visible – less redness, less flakiness, and a more even, healthy glow.
2. COSRX The 6 Peptide Skin Booster
Glow Up, Firm Up, Level Up.
Think of this as your skin’s energizing shot. The 6 Peptide Skin Booster is a lightweight serum designed to address a range of concerns. With a carefully curated blend of 6 multi peptides that boost overall skin condition such as pore & sebum, firmness, fine lines, skin texture, skin tone and soothing. It is perfect to use as the first step of skincare routine to prep and boost.
Key Ingredients:
- SH-Polypeptide-121: Collagen Boosting & Plumping
- Copper Tripeptide-1: Retexturize
- Dipeptide Diaminobutyroyl Benzylamide Diacetate: Excess Sebum & Pore Care
- Oligopeptide-68: Brightening
- Palmitoyl Tripeptide-8: Soothe & Reduce Skin Sensitivity
- Acetyl Hexapeptide-8: Smooth Fine Lines & Firmness
Texture & Application:
Light, non-sticky and watery with quick absorption. Use it first in your routine, right after cleansing. It acts like a priming essence – enhancing the effects of your moisturizer and making your barrier routine even more effective.
Pro Tip: This booster works even better when layered under the Ceramide Skin Barrier Moisturizer, amplifying the barrier-strengthening benefits!
Best for:
COSRX The 6 Petide Skin Booster is suitable for all skin types and can be used all day and in any season.
My Experience:
After a few days of morning and evening use, my skin looked brighter and more energized.
Final Thoughts: Are They Worth It?
Absolutely.
COSRX’s new Ceramide Skin Barrier Moisturizer and 6 Peptide Skin Booster make the perfect skincare pair. Use the Peptide Booster first to energize and prep the skin, then follow with the Ceramide Moisturizer to lock in hydration and support your barrier. Together, they build stronger, healthier skin that’s visibly more radiant and resilient.
