DELTA Conditioning Balm for sensitive skin and anti-aging.

DELTA Daily Hydration for combination skin (in summer)

DELTA Rich Daily Hydration for combination and dry skin. (for everyone in winter Oct-Mar)

or combine with your favorite brand:

Retinol Serum ONE 30ml Pflegeserum Vitamin A Einstiegstufe

New, efficient pump dispenserThis advanced vitamin A-based anti-ageing serum promotes cell rejuvenation. It stimulates protein synthesis in skin cells and improves the skin’s barrier function. A rich serum containing three unique retinoids in an advanced delivery system for optimised skin penetration. The unique, patented encapsulation delivery system ensures maximum activity with minimal irritation. This serum has been developed to enhance the effectiveness of other skincare products and reduce the signs of ageing, including wrinkles, fine lines, sagging and loss of volume, as well as pigmentation issues. It can be used in combination with any other DELTA product and should be applied to skin that has not been treated with retinol. The main active ingredients are: Vitamin A (retinol) reduces hyperpigmentation, repairs sun-damaged skin and improves cellular metabolism. Peptide-4 stimulates wound healing and supports the repair of the cellular matrix. Geranyl lipids protects cells from oxidative damage and delays cellular senescence L-Carnosine inhibits glycation and protects the cells. Contains a highly effective antioxidant. Rosehip oil treats scars and dark spots, making them less visible. Fine lines and wrinkles are reduced. Vitamin C supports the distribution of melanin and pigment Vitamin E supports the skin’s moisture balance As always, PARABEN-FREE. Combined with a Conditioning Balm from DELTA, you have a complete skincare routine. Use stage one (ONE) first, then stage two (TWO) to achieve optimal results. Start using the retinol serum once a week, depending on your skin’s sensitivity, and gradually increase the frequency until you can use it once a day, preferably in the evening. Apply gradually. Applying a large amount too quickly can trigger retinoid reactions. Gradually apply the serum to the entire face, neck and décolletage. It should not be used at the same time as other retinol products; instead, it is recommended to use the Revitaliser in the morning and the Retinol Serum TWO in the evening after 30 days. After cleansing, wait a total of 5 minutes before applying the Retinol Serum. Use only a pea-sized amount per application. Ideal for ageing, sun-damaged skin. Budget-conscious shoppers and men: Even if you use DELTA Retinol Serum just once a day, you’ll soon look more youthful. However, using less than that is simply not enough. Unlike other retinol products (such as Environ or BelCol), this product can also be used on its own. Rating from Cosmeticanalysis.com: GOOD

Stimulates protein synthesis in skin cells and improves the skin’s barrier function. A powerful serum developed with the maximum permitted concentrations of 3 unique retinoids in an advanced delivery system for optimised skin penetration. The unique, proprietary delivery system ensures maximum activity with minimal irritation. This serum has been developed to enhance the activity of other DELTA products and reduce the signs of ageing, including wrinkles, fine lines, sagging and loss of volume, as well as pigmentation issues. This product does not make the skin sensitive to light, nevertheless, we recommend applying it at night for maximum effect.

Here is the answer from Prof.Dr. Markus Depfenhart, the developer of DELTA: The concentration in DELTA Retinol TWO is 0.3%. According to EU standards, the maximum amount for a ‘non-peeling’ product. However, the encapsulation technology used makes the product stronger and effective over several days. This makes the product maximally effective with daily use.  DELTA Retinol ONE is slightly lower at 0.2%. However, it works like a 1% retinol product.
