DAY is the perfect partner for your day: Thanks to the antioxidant properties and the effective active ingredients, it protects your skin perfectly in everyday life. DAY also boosts the activity of your skin and promotes the formation of important skin building blocks - as a help for self-help.
Dr. Miriam RehbeinDoctor Mi! GmbH, Founder -
Radiant and beautiful skin every day: DAY by Doctor Mi! medical skincare is your perfect companion on your way to achieving this. As an anti-aging day cream, DAY contains some luxurious active ingredient complexes that reliably protect your skin from external influences during the day as well as strengthening it and making it glow from the inside out.
The special anti-aging effect in DAY primarily stems from the unique TECMi!® retinol: Retinol is known as a powerful ingredient with anti-aging effects. The TECMi!® retinol in DAY, however, is an even more effective form of retinol. Thanks to the TECMi!® Technology, in which retinol molecules are encapsulated twice, it can penetrate directly into the lower layers of your skin without any problems. This makes it possible for DOCTOR Mi! medical skincare to ensure that no retinol adheres to your skin surface which would irritate and weaken it, but rather that the retinol molecules immediately arrive where they need to and are able to unfold their full anti-aging effect. Because of this unique form of molecule preparation, our retinol day cream DAY supports you throughout your day in your transition to a healthy, fresh and renewed complexion without irritating your skin. The TECMi!® retinol content is dosed in such a way that using it during the day, even in the summer time, is no problem at all.
Besides TECMi!® retinol, DAY also contains a whole range of other evidence-based, nourishing substances that protect your skin and stimulate cell regeneration. The high proportion of antioxidants, for example, ensures cell renewal and strengthens your skin barrier. Oligo-hyaluronic acid and acetylglucosamine reactivate your skin and foster the body's own production of hyaluronic acid which usually decreases with age and results in wrinkles. DAY also contains ectoin which protects your skin from UV radiation and dryness as well as vitamin B3 (niacinamide) to promote your skin's collagen production, to regulate sebum production and to also make your skin smooth and soft.

For whom is the Retinol day cream DAY by Doctor Mi! suitable?
DAY is an anti-aging day cream with Retinol which is suitable for all skin types: from normal skin to sensitive skin to mature skin as well as skin with pigmentation disorders and impurities.
What benefit does Retinol provide in a day cream?
The discovery of Retinol, vitamin A1, was already awarded the Nobel Prize in 1930 - and for good reason: Retinol has a cell-renewing effect on the skin that has been scientifically proven which, consequently, results in a very high skin-improving and anti-aging effect. Further, treating pigmentation disorders and acne with Retinol yields excellent results. The especially high dosage in DAY makes the cream very effective and provides your skin optimal support throughout the day.
What impact does the encapsulated TECMi!®-Retinol have on the Retinol contained in DAY?
Treating your skin with Retinol brings about many benefits. It is important, however, that Retinol does not remain on the surface of the skin, but actually penetrates into the deeper skin layers where it can achieve the desired effect. If it adheres to the skin's surface, it can cause irritation. TECMi!® Technology encapsulates the Retinol molecules twice allowing them to quickly penetrate into the dermis, the lower layer of the skin, without any problems and set the desired anti-aging effect in motion.
Should I avoid Retinol during the day?
Regular Retinol should be used carefully during the day. The TECMi! Retinol contained in DAY can be used without hesitation due to its ability to immediately penetrate the skin layers. The only important thing is that you then use sunscreen with SPF 50+ all year round. This provides your skin ideal protection. We also recommend doing this in general as the sun is known to cause severe damage to the skin.
Does DAY reduce wrinkles and fine lines?
Yes, Retinol has been scientifically proven to reduce wrinkles and fine lines. For a day cream, the dosage of Retinol contained in DAY is ideal. This allows you to support the formation of new collagen which makes your skin more elastic. Its elasticity is strengthened, and your skin feels rejuvenated.
What options do I have to maximize the anti-aging effect in DAY?
If you want to enhance the anti-aging effect that DAY delivers, Doctor Mi! medical skincare offers you several options:
- As a complement to the DAY anti-aging day cream, we recommend using NIGHT, our effective night cream that provides maximum support for the regeneration of your skin at night.
- Use our skin booster and anti-aging bestseller RED as a special treatment to additionally strengthen the collagen production of your skin as well as tighten and smoothing it. Combining it with our DERMAROLLER whilst microneedling will provide the best results.
Is the Retinol day cream DAY also suitable for pigmentation disorders?
DAY also achieves very good results with pigmentation disorders. From minor imperfections to melasma, DAY successfully nourishes your skin from the inside out, resulting in a more even and clarified complexion.
Tip: For skin with pigmentation disorders, the comprehensive application of the Doctor Mi! MELASMA SET yields excellent results.
Can the DAY anti-aging day cream also be used on thicker men's skin?
With our MEN Line, Doctor Mi! medical skincare has created a care line that is especially tailored to the needs of thicker skin types, like male skin. In search of an anti-aging day cream with Retinol for men, we therefore recommend DAY MEN.
Tip: DAY MEN is also included in our care set for male skin, the MEN SET.
How should I incorporate DAY into my skincare routines?
It is crucial that you adapt your skincare routines to the needs of your skin. Based on the individual requirements that skin can have, Dr. Miriam Rehbein has developed various skincare routines: Here you will learn which products are suitable for your skin's needs, how and in which order you can use your products correctly and and how to nourish your skin, perfectly.
How would you describe the texture and fragrance of DAY?
Our Retinol day cream has a natural scent. Doctor Mi! medical skincare completely avoids artificial fragrances which can aggravate and irritate the skin. The texture is light and soft and is quickly absorbed.
