[Benefits of volumetric to facial rejuvenation. Part 2: Dermal fillers].

Injectable substances known as fillers are used to palliate age-related atrophy and ptosis, and for their so-called "pseudo-lifting" action. They do not replace face and neck lift, but allow it to be postponed or, when injected after surgical lifting, make the result durable. Hyaluronic acid has a predominant and unchallenged place among fillers, well ahead of poly-L-lactic acid or calcium hydroxyapatite.

Retinaldehyde/hyaluronic acid fragments: a synergistic association for the management of skin aging.

Background: Retinaldehyde (RAL) was proven effective in treating photodamaged skin. Topical treatments with specific intermediate-size hyaluronate fragments (HAFi, 50-400 kDa) have been shown to stimulate keratinocytes proliferation and epidermal hyperplasia. The aim of this open, multicentric, international study was to assess the efficacy of the combination RAL-HAFi in the correction of skin photoaging.

Fragrance allergy: assessing the safety of washed fabrics.

Background: Previously, a quantitative risk assessment suggested there was no risk of induction of fragrance allergy from minor residues of fragrance chemicals on washed fabrics.

Objective: To investigate whether there was any risk of the elicitation of contact allergy from fragrance chemical residues on fabric in individuals who were already sensitized.

Methods: Thirty-six subjects with a positive patch test to isoeugenol (n = 19) or hydroxyisohexyl 3-cyclohexene carboxaldehyde (n = 17) were recruited.

[Adverse reactions to injectable fillers].

The number of "fillers" grows constantly and allows responding to an ever larger demand with mostly hyaluronic acid or collagen based products. However, products degrading more slowly, containing polylactic acid or bioactive ceramics. All these products bring in general satisfactory results.
