WIMJ Team
One of the few well researched potent anti-aging ingredients. When it is able to penetrate the skin in an active state, it is effective against fine lines and wrinkles, helps improve skin elasticity and reduce hyperpigmentation. It acts as a powerful anti-oxidant and stimulates collagen production. The main issue with ascorbic acid is that it is highly unstable, in other words, it is losing its effectivenss quickly when exposed to air and light (if a serum or cream containing ascorbic acid has an orange color, it is a likely that the ingredient has oxidized and is no longer active). In addition, it is water-soluble, meaning that it has difficulty penetrating the skin. It is also quite irritating, and can cause stinging. When used in low concentrations, helps stabilize the product formulation

50 | Female volunteers aged 30-65 years; Women showing the presence of facial wrinkles, skin sagging, skin dryness, or uneven skin color were included in the study. | topical treatment containing vitamin C, vitamin E, and raspberry leaf cell culture extract | Skin was found to be significantly lighter in color and higher in elas-ticity on the treated side, compared to the untreated side, after 8 weeks of product use (Figure 1A,B), whereas skin radiance im-proved significantly after both 4 and 8 weeks of use. No significant changes in skin moisture level (P > .9999) or TEWL. |

20 | 20 women (mean age 42 years).Main inclusion criteria were: women aged from 35 to 45 years, with a phototype (Fitzpatrick): I-III, residents in a homogeneous urban area, compelled to spend at least 2 hrs a day outdoors, with at least three dark spots on the face without any other facial skin diseases | The subjects were instructed to apply the tested product (Endocare-C Edafence serum; Cantabria Labs, Madrid, Spain) at home under the normal conditions of use, for 28 consecutive days, on the entire face. The product was applied on the face twice daily (in the morning and in the evening). In particular, specific instructions were given to each subject for the correct application of the tested product: 1) do not wash the face after the application of the serum; 2) do not apply any other skincare products and 3) do not use any make-up products during the study period. The serum contained deschampsia antartica aqueous extract, ferulic acid, vitamin C (ascorbic acid), and standardized Crypthomphalus aspersa sectretion (10%) | In comparison with baseline, the product induced a significant improvement of skin hydration (−19% of TEWL), a significant improvement of dark spots (+7%) and a significant improvement of SQOOH/SQ ratio (−16%). The product was evaluated very well by >90% of the treated subjects regarding cosmetic acceptability. |

20 | Healthy female volunteers presenting with photoaged skin on their low-neck | The left or right half of the upper chest and the corresponding forearm were randomly assigned to once a day application of a fingertip unit of either 5% vitamin C (ascorbic acid) cream or excipient alone. Each patient received a randomized pair of identical-appearing tubes, color coded and labeled right or left. . Clinical assessments included evaluation at the beginning and after 3 and 6 months of daily treatment | A highly significant increase in the density of skin microrelief and a decrease of the deep furrows were demonstrated. Ultrastructural evidence of the elastic tissue repair was also obtained and well corroborated the favorable results of the clinical and skin surface examinations. Topical application of 5% vitamin C cream was an effective and welltolerated treatment. It led to a clinically apparent improvement of the photodamaged skin and induced modifications of skin relief and ultrastructure, suggesting a positive influence of topical vitamin C on parameters characteristic for sun-induced skin ageing. |
