Vitamin A Therapy

Infographic: semi-circular diagram showing 5 benefits of vitamin A, numbered: 1 Vision (eye), 2 Immune system (molecule), 3 Anti-inflammatory (flame), 4 Cancer prevention (bow tie), 5 Cell growth & skin (skin).

Five brands in our portfolio offer vitamin A day creams: Delta, Environ, Juliette Armand, BelCol and Mokann. Each has its own approach and features a unique combination of active ingredients.
We offer a body oil PREMIUM with a high vitamin A content.

Do not combine Vitamin A products at the same time, as an overdose can stress the skin and lead to redness.

Vitamin A in skin care products must be metabolised into retinoic acid so that the skin can process it.
So higher is not necessarily better. DELTA RETINOL ONE and DELTA RETINOL TWO delivers vitamin A to the skin already in the form of encapsulated retinoic acid (medically approved) and is therefore the most modern product.

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.

Retinol Serum ONE 30ml Pflegeserum Vitamin A Einstiegstufe (50% grösser)

New packaging - Larger than before and new, more efficient pump dispenserThis highly developed vitamin A-based anti-ageing serum promotes cell rejuvenation. Stimulates protein synthesis in the skin cell and improves the skin’s barrier function. A rich serum with 3 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 was developed to increase the activity of other skincare products and to reduce the signs of ageing, including wrinkle formation, fine lines, sagging and loss of volume as well as pigmentation problems. It can be used in conjunction with any other DELTA product and should be applied to skin untreated with retinol.  Main active ingredients are: Vitamin A (retinol) reduces hyperpigmentation, restores sun-damaged skin and cellular metabolism is improved. Peptide-4 stimulates wound healing and supports the repair of the cell matrix. Geranyl lipids protects the 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, these become less visible. Fine lines and wrinkles are improved. Vitamin C supports melanin or rather pigment distribution Vitamin E supports moisture balance as always PARABEN-FREE. Together with a Conditioning Balm from DELTA you have the complete skincare. Use level one (ONE) first then level two (TWO) to achieve optimised results. Begin with the Retinol Serum, depending on sensitivity, once per week and build up the dose slowly until you can use it once daily, preferably in the evening. Apply gradually. a larger amount applied too quickly can cause retinoid reactions. Apply the serum gradually to the entire face, neck and décolletage. Should not be used at the same time as other retinol products but it is recommended to use the Revitalizer in the morning and the Retinol Serum TWO in the evening after 30 days. Wait a total of 5 minutes after cleansing before applying Retinol Serum. Use only a pea-sized amount per application. Ideal for ageing, sun-damaged skin. Bargain hunters and men: even if you use DELTA Retinol serums only once daily, you will soon look more rejuvenated. Less is however too little. In contrast to other retinol products (such as Environ or BelCol), this product can also be used entirely on its own. Rating Cosmeticanalysis.com GOOD
