The Best Ingredients for Healthy Skin – What Really Helps According to Dr. Emi Arpa

FITBOOK: What are the best ingredients in skincare?
Dr. Emi Arpa: “First of all, we all need a healthy skin barrier. I’m a huge fan of ceramides because they are also an important part of our skin’s natural barrier. It’s great to protect our skin with them, especially now in winter. Then I love ingredients that are really well-researched. And it’s well-known that retinoids are particularly sustainable, especially in skin regeneration and collagen synthesis stimulation. Especially retinal—if it’s encapsulated, it’s a top choice for me. Then I would perhaps mention a group of antioxidants. There are, for example, vitamin C derivatives. But also astaxanthin, which is 65 times more effective than vitamin C and can boost our UV protection and protect our skin from oxidative stress.”

Why Fermented Ingredients (Postbiotics) Are a Gamechanger in Skincare

Which ingredients do you think are completely underestimated in their effect?
“Fermented ingredients are underestimated, so-called postbiotics. They can help stabilize the entire formulation of a skincare product and perhaps even ensure that the ingredients penetrate the skin more effectively; they really reach where they are supposed to. I’m a big fan of Bifida Ferment Lysate. This ingredient helps very well against redness and generally against impurities.”

Dr. Emi Arpa: “Encapsulated Retinal Serum Is the Best Investment, But …”

If you had to choose one skincare product, which would it be?
“Well, if I could only spend money on one skincare product beyond sunscreen, it would be a retinal serum. But I would make sure that this retinal serum is encapsulated and also contains peptides to stimulate collagen synthesis and strengthen our skin barrier.”

How to Avoid Marketing Traps in Skincare Products

How do you recognize a good skincare product?
“When evaluating a product and deciding whether you want to afford it, you should always check all the ingredients it contains. You shouldn’t buy a product just because, for example, retinol is included. It always depends on the overall formulation. Peptides, for example, fuel collagen stimulation, ceramides like ectoin and allantoin support the skin barrier and ensure that side effects don’t occur in the first place.”
