Arm Intervention/treatment
Active Comparator: Control Group
Participant will receive sunscreen in the morning and at the beginning of the afternoon for 3 months.
Other: Sunscreen
Participants will apply a dime size amount of sunscreen to cover the other half of the face.

Experimental: Liftactiv B3
Participants will undergo a wash out phase of two weeks where they regularly apply a moisturizer (Hydreane Legere) in the morning and a sunscreen in the morning and at the beginning of the afternoon. On the 3rd week, participants will apply Liftactiv B3 serum daily in the morning before sunscreen and in the evening (two applications daily) on half face for 3 months.
Drug: Liftactiv B3
Participants will apply a dime size amount of the serum to 1 side of the face.

Primary Outcome Measures :
  1. Post Inflammatory Hyperpigmentation (PIHP) change [ Time Frame: Baseline to 3 months ]

    Post Inflammatory Hyperpigmentation (PIHP) will be evaluated using the post acne hyperpigmentation scale.

    The total score can range from 6-22 points. Subscales will measure lesion size, lesion intensity, and number of lesions. Subscales are added together to form the total score. Higher values indicate worse hyperpigmentation.

Secondary Outcome Measures :
  1. Change in the Investigators Global Assessment (IGA) scale [ Time Frame: At baseline, 1 month, 2 months and 3 months ]
    Pigmentation will also be evaluated clinically using the Physician global assessment IGA defined as none is 0, minimal is 1 or mild disease is 2 within the treatment area.

  2. Change in skin condition evaluation scores [ Time Frame: Baseline, 1 month, 2 months and 3 months ]
    Clinical evaluation of skin condition on subject's face which includes deep wrinkles, fine lines, skin tone, skin texture, radiance and skin elasticity will be evaluated using a 10 point Likert Scale. Each of these conditions will use the same Likert Scale from 0 to 9 with the higher score indicating more severe/worse symptoms.

  3. Change in Global Efficacy Assessment [ Time Frame: 1 month, 2 months and 3 months ]

    Global efficacy of the treatment evaluated at each visit by the patient.

    The measure of the global efficacy will be realized according to the Global efficacy scale which ranges from nil to excellent which will be measured from 0 (equals nil) to 4 (equals excellent).

  4. Change in Global tolerance score [ Time Frame: 1 month, 2 months and 3 months ]
    Clinical tolerance global score will be assessed, on the treated area, at each visit using first a 4-point skin reaction scale which ranges from 0 which indicates no evidence of local intolerance and 4 indicates very severe signs or symptoms of intolerance.

  5. Change in Cosmeticity Questionnaire and Acceptability [ Time Frame: 1 month, 2 months and 3 months ]

    Subjects will be questioned about their perceived effects of the investigational product on their skin.

    The cosmeticity questionnaire is a 5 point scale (1-fully disagree; 2-disagree partly; 3-no opinion; 4-agree partly; 5-fully agree).

  6. Change in Exposome Questionnaire [ Time Frame: Baseline and 3 months ]
    Subjects will be questioned about their perceived effects of the investigational product on their skin. Five different answers will be proposed: (0)Fully disagree, disagree partly, no opinion, agree partly, (5) fully agree.
