Product description
Important: Please Read
How do I use it?
Start with every other night for the first two weeks, using a small amount on targeted areas. If your skin feels sensitive, reduce use and apply a calming moisturizer. Avoid the eye area and wash hands after use.
Can I use it in the morning?
We recommend using this product at night only. Since the formula contains retinal, be sure to apply sunscreen the next morning to protect your skin.
Will this product cause my skin to look yellow?
Our formula contains a high concentration of retinal, a naturally yellow ingredient. This may give skin a slight yellow tint right after application, but it is temporary and washes off completely with cleansing.
Why doesn’t the tube look completely full?
For product stability, the tube may not look completely full. Don’t worry — it contains the exact amount stated, so you can use it with confidence.
What if my skin feels sensitive after use?
As this formula works effectively, you may experience mild sensitivity like redness or peeling. We suggest a quick patch test before first use, and simply adjust frequency to keep your skin comfortable.

Retinal Duo Gift Set: A special 2-piece retinal set created just for Amazon shoppers, inspired by customers who keep this formula in their routine and their feedback. Perfect for gifting.
High-Strength 0.1% Retinal Care: Powered by 0.1% retinal — a more advanced form of retinol — and A-Shot technology, this formula helps deliver actives deep into pores for smoother, firmer-looking skin and more refined pores.
A refined micro-particle ingredient, 16 times thinner than pores, is designed to penetrate directly into pores and enhance the absorption of active ingredients. Through high-purity separation and refinement, the particles are uniformly sized, reducing skin irritation.
Liposomized Retinal & Matrixyl: A liposomized retinal and Matrixyl formula that targets the look of wrinkles, uneven texture, and enlarged pores, giving troubled areas a more elastic, refined appearance with just a few drops.
Micro-Particle Delivery System: Ultra-fine particles, about 16x thinner than pores, are designed to fit into pores and support better absorption while maintaining a uniform size to help minimize irritation.
Beginner-Friendly Usage: New to retinol or retinal? Start every other night for the first 2 weeks, using a small amount on targeted areas. A slight yellow tint on the skin after application is normal and rinses off completely during cleansing. It’s a perfect set to gift to anyone trying retinal for the first time.
