Is a Cosmetic More Effective if Combined With Its Food Supplement?
HYALURONIC ACID (HA) HAS LONG BEEN USED FOR ITS ANTI-AGE PROPERTIES, AS AN INGREDIENT IN BOTH TOPICAL APPLICATIONS AND FOOD SUPPLEMENTS.
In this study, a novel sodium hyaluronate, based on the innovative full spectrum technology, was administered as an ingredient of a cosmetic product and as the main constituent of a food supplement to evaluate its efficacy in counteracting skin ageing signs.
- COMPLIFE ITALY LABS, PAVIA
- 75 MATURE FEMALE SUBJECTS
- 4 WEEKS OF PRODUCTS ADMINISTRATION + 1 WEEK OF FOLLOW-UP
- RANDOM TREATMENT ASSIGNMENT:
- ACTIVE FOOD SUPPLEMENT + PLACEBO COSMETIC PRODUCT,
- ACTIVE COSMETIC PRODUCT + PLACEBO FOOD SUPPLEMENT,
- BOTH PRODUCTS CONTAINING THE ACTIVE INGREDIENT (“IN&OUT” TREATMENT)
MORE EFFICIENT, LONGER
Improvement of all the outcome measures (skin moisturization, elasticity, firmness and profilometry)
was achieved by all treatments (p < 0.05); however, the combined treatment resulted in a further
amelioration of the skin aging signs with respect to the two single active treatments (p < 0.001), and
such effect lasted also after the follow-up period.
In conclusion, such results confirmed that the concomitant administration of hyaluronans by these two different routes represents more than an interesting approach to counteract skin aging signs.
