Pharmaceris A A&E Sensilix Duo Concentrate is a specialized serum formulated for allergic and sensitive skin. It contains 27.3% squalane, Vitamin A (0.2%), and Vitamin E (5%) to help prevent micro-irritation, enhance skin's antioxidant properties, and slow down physiological aging. The serum is particularly effective for skin that has become thinned, fragile and rough due to aging and environmental factors. It contains nourishing oils including rapeseed, hempseed, and almond oil. For best results, apply at night to cleansed face, neck and décolletage, followed by regular face cream. A minimum one-month treatment is recommended for optimal results on dull and overly dry skin. The unscented formula has been clinically and dermatologically tested for safety and efficacy on sensitive skin.
