Experience how your skin gains vitality day after day and reveals a healthy, radiant complexion.
The power of ingredients that transform your skin
The unique effect of K-Secret Seoul Serum is based on a carefully selected combination of key ingredients that work in synergy to achieve optimal results:
- Retinal (2% liposomal encapsulated): One of the most potent forms of vitamin A (a retinoid), retinal acts directly on cell renewal. It promotes collagen production, visibly reduces fine lines and wrinkles, improves skin elasticity and refines skin texture. The liposomal encapsulation ensures a more stable and tolerable delivery of the active ingredient to the skin, which minimizes the risk of irritation.
- Black Ginseng (Panax Ginseng Root Extract): A traditional K-Beauty power ingredient known for its revitalizing and antioxidant properties. Black ginseng protects the skin from environmental damage, improves circulation, promotes skin firmness and gives a radiant, healthy complexion.
- Niacinamide (vitamin B3): This multitasking ingredient strengthens the skin barrier, helps minimize pores, reduces redness and evens skin tone. It is an excellent partner for retinal as it soothes the skin and improves its resilience.
- Bakuchiol: Often referred to as a herbal alternative to retinoids, Bakuchiol works synergistically with Retinal. It boosts the anti-ageing effect, has an antioxidant effect and can also help to soothe the skin and increase the tolerance of the serum.
- Peptide complex (SH-Oligopeptide-1, SH-Oligopeptide-2, SH-Polypeptide-1): These signal peptides play a crucial role in skin regeneration and repair. They promote collagen synthesis, improve skin elasticity and contribute to a firmer, plumper complexion.
- Vitamin C Derivative (3-0-Ethyl Ascorbic Acid) & Vitamin E (Tocopherol): An antioxidant power combo that protects the skin from free radicals, brightens the complexion and promotes overall skin health.
How to integrate the K-Secret Seoul Serum into your evening routine
For optimal results and to get your skin used to the retinal, we recommend a gradual introduction:
- Cleansing: Start with a thorough cleansing of your face to remove make-up and impurities.
- Toner (optional): Apply a moisturizing toner to balance the pH of your skin and prepare it for the products that follow.
- Serum: Apply 1-2 pumps of K-Secret Seoul Serum to your fingertips and gently smooth over your face and neck. Avoid the eye area.
- Moisturizer: Finish your routine with a nourishing moisturizer to hydrate the skin and lock in the active ingredients.
Pro tip: Start by applying 2-3 times a week in the evening and slowly increase the frequency depending on how your skin reacts. As retinal can make the skin more sensitive to light, daily use of a sunscreen in the morning is essential.
Complete your routine for maximum results
For a comprehensive K-Beauty routine and to maximize the anti-aging effect, we recommend combining the K-Secret Seoul Serum with other products from the same line:
- Step before the serum (Essence): K-Secret Seoul 1988 Essence: Snail Mucin 97% + Rice - This moisturizing essence optimally prepares your skin for the serum, provides intensive moisture and promotes skin regeneration with snail mucin and rice extract.
- Daily protection (sun protection in the morning): K-Secret Seoul 1988 Sun: Pine Tree + Ceramide SPF 50+ PA ++++ - An absolute must, especially if you use Retinal. This lightweight sunscreen effectively protects your skin from UV rays and also provides it with strengthening ceramides.
Any questions about K-Secret Seoul Serum?
How do I start using Retinal?
As Retinal is a potent active ingredient, we recommend gradually integrating K-Secret Seoul Serum into your routine. Start with 2-3 applications per week in the evening. Observe how your skin reacts. If no irritation occurs, you can slowly increase the frequency to every other evening or, if well tolerated, daily. Slight redness or dryness at the beginning is normal and should subside over time.
Can I use the serum every day?
Yes, if well tolerated, K-Secret Seoul Serum can be used daily in the evening. However, it is important to gradually accustom the skin to the active ingredient and to pay attention to its signals. If irritation persists, reduce the frequency of application.
Do I need to use sun protection when I use Retinal?
Absolutely! Using Retinal makes your skin more sensitive to sunlight. A daily, highly effective sunscreen with at least SPF 30 (ideally SPF 50+) is essential to protect your skin from UV damage and ensure the effectiveness of the serum. Apply it every morning as the last step of your skincare routine.
