BLUE RETINOL serum by BIOTHERM. It is a powerful innovation born from Bioscience that offers our highest renewal efficacy in a vegan formula*. (*without ingredients or derivatives of animal origin) Every night, it targets wrinkles, evenness and skin quality to reveal healthier, younger-looking skin every day.
Biotherm's new facial serum is made up of the main ingredients:
PURE RETINOL 0.25%: Pure form of vitamin A, it is a benchmark anti-aging dermatological ingredient. It is known for its great effectiveness in skin renewal: reduction of wrinkles, uniformity of the skin and improvement of its texture.
LIFE PLANKTON 1%: natural ingredient to help the skin in the self-regeneration process.
NIACINAMIDE 3%: Also known as vitamin B3. Helps protect and soothe the skin and has powerful anti-pigmenting activity.
FAITHFUL TO OUR BLUE COMMITMENTS: Vegan formula: 92% biodegradable. Eco-designed packaging: 25% recycled glass bottle.
TEXTURE A creamy and pleasant serum texture. It glides on smoothly and penetrates deep into the skin to provide all its renewing and repairing action. It is not sticky or greasy and leaves the skin comforted and nourished.
Containing Pure Retinol, this texture may take on a slightly yellow appearance over time. It is totally normal and safe for your skin. The truth is that Retinol in its purest form is subject to oxidation, hence the color change.
Suitable for normal to oily skin.

How to use:
DIRECTIONS FOR USE: Apply at night on the face. For the first week, use twice a week, then gradually increase the frequency to every other night. If the discomfort persists, space the applications and/or reduce the quantity. Always make sure to provide good hydration to your skin. Apply every night before your moisturizer. Avoid the eye contour and eyelids. Avoid using in combination with retinol products outside the BIOTHERM Blue Pro-Retinol range. Do not intentionally expose the skin to the sun and use a broad-spectrum sunscreen product with SPF 30 daily.

Night serum: soft, hydrated, and radiant skin
This night serum is incredible. It has a lightweight texture that absorbs quickly, leaving my skin super hydrated but without any greasy feeling. When I wake up, my skin feels so much softer, fresher, and more radiant. I love how it improves the appearance of my face, making it look more rested. It’s ideal for anyone looking for something easy to use that actually delivers results. I highly recommend it!

Smoothing effect!
I recommend it 100%! Not only does it hydrate and reduce expression lines and spots, but it also leaves your skin smooth and firm, like the feeling after a peeling but with hydration and a firming effect. It is without a doubt the best night serum I have ever tried and I have tried many. Thank you Biotherm

New face!
My sister gave it to me because it was very strong for her, and I used it and I remember that it left my skin perfect, with luminosity, as if my skin had been polished and left new.

Apply at night to a clean face. As it contains pure retinol, it is recommended to start gradually and always use sunscreen the following morning.

Hello Belen! Thank you for your inquiry. This serum would be applied in the night routine, before the moisturizer. Greetings!
