I received this product for free from Influenster and COSRX. However, my review is honest and my own. I love how this feels during application to the skin. The smoothness is like a dream. I definitely saw and felt immediate moisture relief and felt glowy. I do think it has helped a little so far with fine lines. No irritation as of yet.
Effective yet gentle

Great addition to your nighttime routine. Results take time but that's with any retinol. Gentle enough to be used daily, if you've built a tolerance. Def would recommend to anyone who's wanting try incorporate or try a new retinol
One of the best oil serums I've used

I really love this serum. I'm 28, so I'm using it more as a preventive measure, a few drops at night every other day. It really smooths my skin and makes me look so much more glowy and even. I really appreciate this product and will keep buying it!
Smooth product leaves me with smooth skin

This product is really nice. I use it as directed, couple of drops, and I never experience dry skin. I use it at night and the next day my skin looks hydrated and plump. Honestly if you use retinol, then you will recognize the quality of the serum! It's so smooth. I love this product and will continue to buy!

- Q
Is this product good for those 11 lines
- Asked by Melissa
- Official Answer By COSRX - Brand EngageThis product is designed to help improve the appearance of fine lines and wrinkles, including those around the forehead. Retinol is known for its ability to promote cell turnover and stimulate collagen production, which can contribute to smoother and more youthful-looking skin. However, it's important to start using retinol products gradually, especially if you are new to retinol. We recommend applying it a few times a week and gradually increasing usage as your skin builds tolerance. Additionally, always remember to use sunscreen during the day, as retinol can make your skin more sensitive to sunlight.Was this answer helpful to you

- Asked by Maggie

- Q
Do I still use a moisturizer with this product? Can a moisturizer be applied first & then this retinal oil?
- Asked by Golden Girl
- Official Answer By COSRX - Brand EngageYes, it is important to follow up with a moisturizer when using the Retinol 0.5 Oil. Retinol can sometimes cause dryness or irritation, so applying a moisturizer afterward can help to keep your skin hydrated and balanced. As for the application order, it is generally recommended to apply the Retinol 0.5 Oil first, and then follow up with your moisturizer. This allows the retinol to absorb effectively into your skin. However, if you find that your skin is sensitive, you can apply a moisturizer first to create a barrier, then apply the retinol oil on top. Always remember to patch test new products and introduce retinol gradually into your routine, especially if you are new to using retinol.Was this answer helpful to you
