Key Benefits of Control Corrective Skincare Systems Exfo Tonic

These are the key benefits you can expect from using Control Corrective Skincare Systems Exfo Tonic:

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Control Corrective Skincare Systems Exfo Tonic has a slight anti-wrinkle rating of 0.9 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈3.0%),

a highly effective ingredient in peelings but with moderate anti-wrinkle efficacy in leave-on skincare products, as supported by a single clinical study. This study, involving 72 participants (Thibault et al.), demonstrated that a lotion with 5% GA reduced the fine wrinkling score by 6% after 34 days of use, compared to a vehicle (the same formulation without GA).

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Rich in Skin-Protecting Antioxidants

We estimate that Control Corrective Skincare Systems Exfo Tonic is rich (> 3%) in antioxidants, specifically Hamamelis Virginiana (Witch Hazel) Extract (est. ≈4.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Skin Soothing and Calming Potential

Based on the ingredient list analysis, Control Corrective Skincare Systems Exfo Tonic is rich (> 5%) in soothing ingredients, particularly Hamamelis Virginiana (Witch Hazel) Extract (est. ≈4.0%) and Salicylic Acid (est. ≈2.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.
