Serum – Active ingredient concentrates for visible results

Serums are highly concentrated formulations with a light texture that specifically target skin needs such as hydration, evenness, or regeneration. They are used after cleansing and before moisturizer – a few drops are enough for noticeable effects.

What is a serum?

Unlike creams, serums contain significantly more active ingredients and less oil. Their fine texture facilitates the absorption of these active ingredients into the upper layers of the skin. Consumer tests classify facial serums primarily as moisture boosters ( Stiftung Warentest ).

How serums work

The effect depends on the ingredients. Hyaluronic acid binds water and plumps the skin superficially; exaggerated anti-aging claims should be viewed critically ( ÖKO-TEST: Hyaluronic Acid Serums ). As a general rule: Serums are an effective supplement to basic skincare, but do not replace it ( Stiftung Warentest: Hyaluronic Acid in Cosmetics ).

Typical active ingredients in serums

• Hyaluronic acid: binds moisture and improves skin smoothness in the short term ( Consumer Advice Center ).
• Vitamin C (ascorbic acid): antioxidant, supports evenness and radiance ( PTAheute ).
• Niacinamide: strengthens the barrier, can reduce redness and shine ( PTAheute ).

Application & Sequence

After cleansing, apply 1–3 drops of serum to the face and neck and gently pat in, then cover with a cream. Antioxidant serums are suitable for the morning, while moisturizing or regenerating serums are recommended for the evening. Tests and guides emphasize that a well-tolerated moisturizer remains the foundation of your skincare routine ( ÖKO-TEST: Skincare Guide ).

Mistakes to avoid

• Layering too many active products can promote irritation.
• Relying solely on "anti-aging miracles": Evidence is often limited; pay attention to solid basic skincare ( Stiftung Warentest: Anti-wrinkle creams ).
• Don't forget SPF: especially when using vitamin C, AHA/BHA or retinoid serums, remember to use daily UV protection.

Conclusion

Serums are highly effective additions to your daily routine. When chosen correctly and used consistently, they deliver measurable benefits – especially in terms of hydration, evenness of complexion, and protection against oxidative stress.
