COSRX The Retinol 0.5 Oil uses 0.5% stabilized pure retinol, not derivatives, combined with Super Vitamin E (tocotrienol) and squalane for improved elasticity and hydration. This formula delivers high-strength care for firmer, youthful-looking skin while remaining barrier-safe and suitable for acne-prone or sensitive skin types that have built retinol tolerance.
Clinical studies show visible skin improvements after 2 to 4 weeks of use: pores improved after 2 weeks, and wrinkles after 4 weeks. Notably, pore volume and area were reduced by over 45%, forehead wrinkles decreased by 22%, and eye area lines improved by 17%, based on testing by the Dermacosmetic Skin Science Laboratory.
Yes, it’s suitable for acne-prone skin. The formula includes squalane and vitamin E to help reduce dryness and irritation while retinol works on the appearance of clogged pores and uneven texture.
Use 2–3 times a week at night for the first 2 weeks, applying 1–2 drops only to areas of concern (or mix with your moisturizer for a gentler start). From Week 3, you may use it every other night and spread a thin layer over the entire face if your skin feels comfortable. Always follow with sunscreen during the day.
With continued use, the skin becomes firmer, smoother, and more radiant. The 0.5% pure retinol boosts collagen production, softens fine lines, and improves uneven tone while vitamin E and squalane strengthen the skin barrier.
It can be used with barrier-supporting or hydrating products, but avoid combining with exfoliating acids (AHAs, BHAs) or high-concentration vitamin C in the same routine. For best results, use retinol at night and pair with SPF during the day to protect renewed skin.
This oil is designed for intermediate to experienced retinol users who are ready for a higher strength (0.5%) formula. Beginners should start with COSRX The Retinol 0.1 Cream or 0.3 Cream to build tolerance before advancing to this concentrated oil.

"I like the gentle way of that retinol working. My skin has never had irritation during using that product. I use it twice a week, in the morning use VitaminE Sunscreen and I like the effect. I have oily skin with acne, post-acne dark spots. As it’s written in the instruction, I keep the bottle in the fridge."
"Still getting used to it, but seeing some results. Just started it regularly in my skincare routine and was scared to upgrade to this from my other retinol as it might irritate my skin, but this retinol oil is super hydrating and all I need on my retinol night is this, eye serum and all in one cream and I feel hydrated all night."
"I love this retinol my skin feels very smooth !"
"I absolutely love this stuff! I use it with the regular retinol as an added layer. Love the way it makes my skin look and feel!!"
"I love the product, it's very good."
"I’ve tried several retinol products before, including Kiehl’s and Geek & Gorgeous, so my skin was already used to retinol when I started this one. After taking the test on the website, I felt confident starting directly with the 0. 5 strength. I’ve been combining it with the booster serum, and the results have honestly surprised me. Within just one week of use, I could already see a visible improvement in my skin’s texture and overall glow. What made it even more impressive is that my family members noticed the difference too, which is a first for me! So far, I’m really happy with the results and excited to see how it continues to improve my skin over time. When traveling, i used a glass dropper bottle to cary it."
