This is a single center, double-blind, randomized, placebo-controlled study, performed on two parallel groups. A total of 130 adult female subjects meeting specific inclusion/exclusion criteria will be included in order to have 120 subjects who complete the study at Day 98/Week 14. Subjects will be randomly assigned to either the FS-HA oral supplementation group (60 subjects) or the placebo group (60 subjects). The subjects should agree to attend a total of five (5) visits as follows: * a screening visit within 21 days prior to Day 1 (from Day -22 to Day -1); * a baseline visit (Day 1); * two (2) intermediate visits (Day 29 and Day 84); * a follow-up and end-of- study visit on Day 98. The primary objective of this study is to evaluate the effects of an oral supplementation containing a FS-HA on facial skin hydration after 3 months of use, compared with Placebo. The Secondary Objective(s) will evaluate the effects of an oral supplementation containing a FS-HA compared with Placebo on: * the hydration of the lips using corneometry; * the skin quality of the face using dermatological assessments and biophysical measurements (TEWL and Mexametry); * the quality/health and beauty of the lips using dermatological assessments and biophysical measurements (Mexametry); * the volume of the lips using image analysis; * to assess the persistence of the effects 2 weeks after discontinuation; * to assess the subject perceived efficacy and acceptability (subject self-assessment); * to evaluate the safety of the study products.

Skin hydration
Facial skin hydration (Corneometer)
Time frame: Change from baseline to 3 months
Lip hydration
Changes in lip hydration (Corneometer®)
Time frame: From baseline to Day 29, Day 84 and Day 98 (2 weeks after supplementation end)
Lip color
Changes in skin and lip color (Mexameter®)

Time frame: From baseline to Day 29, Day 84 and Day 98 (2 weeks after supplementation end)
Skin barrier function
The measurement of the TEWL gives an indication of the integrity of the barrier function of the stratum corneum. The TEWL will be measured on the face at each evaluation visit using a Vapometer SWL-2 (Delfin, technologies, Kuopio, Finland). This portable device contains moisture sensors in a closed chamber type probe. The conditions of a closed chamber are created by contact with the skin surface (surface of the chamber =1 cm²). The TEWL measurement is expressed in g/m²/h after a stabilization time of 10 to 20 seconds.
Time frame: From baseline to Day 29, Day 84 and Day 98 (2 weeks after supplementation end)
Dermatological assessment of skin face
Scoring system for the assessment of the skin face Skin dryness : 0= no dryness to 9= very dry skin Skin roughness : 0= no roughness to 9= severe roughness Skin evenness : 0= not even at all to 9= very even Skin suppleness : 0= not supple at all to 9= very supple skin Skin elasticity : 0= no elasticity at all to 9= maximal elasticity Skin firmness 0= no firm at all to 9= very firm Skin plumping 0= not plump at all to 9= very plump
Time frame: From baseline to Day 29, Day 84 and Day 98 (2 weeks after supplementation end)
Dermatological assessment of lips
At each evaluation visit, the lip qualities will be assessed by the Investigator/evaluator using the following 6-point scoring system from 0 to 5. Lips fullness 0= very thin to 5= very full Lips dryness 0= no dryness to 5= very dry lips Lips roughness 0= no roughness to 5= severe roughness
Time frame: From baseline to Day 29, Day 84 and Day 98 (2 weeks after supplementation end)
Self assessment questionnaire
1. Evaluation of the skin face : wrinkle, hydration, firmness, softness, radiance, plump (scores from 0 (not) to 3 (high)) 2. Evaluation of the lips : hydration, volume, fine lines, color, gloss (scores from 0 being mild and 10 very strong) 3. Evaluation of hair quality : volume, growth, loss, strength, radiance (scores from 0 (not) to 3 (high)) 4. Evaluation of the nail quality : strength, radiance, frailty, growth (scores from 0 (not) to 3 (high)) 5. Joint health
Time frame: From baseline to Day 29, Day 84 and Day 98 (2 weeks after supplementation end)
