If you search for retinol products, you will find countless products on the Internet. Unfortunately, it is not obvious to end consumers that some products have an inadequate effect and therefore hardly any effect at all. If you then decide on a product and only later find out about a better alternative, the frustration is great. In this buying guide, our editorial team from Apotheken-Warentest has compiled all the important criteria for evaluating the products on the market and analyzed the test winner.

For years, retinol has been THE active ingredient that women around the world turn to when it comes to anti-ageing, blemishes and even skin - an all-rounder. New studies have now confirmed this: Retinol tightens the skin and can even reverse the degradation of the skin caused by ageing. Wrinkles on the mouth, eyes and forehead are said to be reduced by 40% after just a few weeks. Retinol also stimulates and boosts regenerative processes in the skin. Many users report enthusiastically: "My skin feels ten years younger!"

But caution is advised here too: There are also big differences with retinol! Scientists report that it depends on the composition and the method of application.

We uncover the biggest myths about retinol for you and show you what to look out for when buying. We have conducted independent research for you and selected the top 3 best retinol products. Our short guide will give you all the knowledge you need to never waste your money on worthless hyaluronic acid products again. So you can achieve maximum results.

Studies have long proven the effectiveness of retinol.

There are now many placebo-controlled studies that prove the visible effect of retinol. We present a small selection here:

1st Munich study: Increasing the regeneration of the skin

A clinical study conducted by the Ludwig Maximilian University of Munich focused on the influence of retinol serums. The study observed 76 women and analyzed the ability of the skin to regenerate itself. The results showed that, compared to a placebo, the retinol serum used had a significant increase in regenerative effects in the skin.

2. further Munich study: Reduced wrinkle depth after 3 months

In another clinical study with 20 participants, divided into four groups, a retinol serum for daily use was tested. Wrinkle depth and skin firmness were measured before and after a 3-month application phase. The results showed that the depth of wrinkles was reduced by up to 20% after just 3 months and the skin was tightened by up to 30%.

3 University Hospital Basel: Slowing down the ageing process

A joint research project between the School of Medicine in Thessaloniki and the University Hospital Basel revealed back in 2012 that retinol is able to slow down the ageing process.

As we have learned in the previous lines, retinol has a good reputation in terms of skin care, skin health and anti-aging effects for justified and even scientifically confirmed reasons.

However, it can be assumed that not all retinol products are of the best quality.

To really benefit from the advantages of retinol, you should keep a few points in mind. You can read about these in the following section:

Criterion1: Serums are usually purer than creams and therefore the most effective

Criterion 2: Best result when retinol is delivered deep into the skin

Criterion 3: Quality before quantity

We have analyzed dozens of scientific studies for you and tested the most promising products on this basis. Here we present the 3 best retinol serums and the test winner.

We have also based our assessment on the above criteria and included verified product reviews from female testers.

DULEXIR RETINOL 

The German pharmacy brand Dulexir has developed a unique formula that cannot be found anywhere else.

They have developed a new active ingredient complex - the "Dulex Acid Complex" - which enables retinol to penetrate both the skin and deep into the skin and positively influence particularly deep-acting processes in the skin. In this way, the blockages on the skin can be bypassed.

Mode of action: 2-stage effect - In the first stage, the skin is freed from its blockage and in the second stage it is then deeply nourished with hyaluronic acid.

The customer reviews are consistently positive. Several customers report a refreshing effect on the skin, good skin tolerance and a visible reduction in wrinkles. 86.7% of customers give it 5 out of 5 stars.

One bottle contains 50 ml and costs from €33.30 - lasts for approx. 3 months.

The manufacturer also offers a 60-day trial period during which you can try out the serum freely. If you are dissatisfied, you can simply cancel your order within the 60 days and receive a full refund.

Cosmetics Serum - KU2

This serum from KU2 Cosmetics is a simple, high-quality and versatile product with a concentrated amount of retinol. It helps to boost the processes in the skin and thus ensures smoother and plumper skin.

The KU2 company is popular with beauty enthusiasts. Not least because all products have been developed in collaboration with cosmetic scientists. In addition, regular laboratory tests ensure that effectiveness and safety are guaranteed. The only drawback: although the product appears to be of high quality overall, we have found that some users report a rather sticky consistency. It often takes longer to fully absorb into the skin than comparable products.

Price: 169,67 € / 100 ml
