This routine should be used in the following order to achieve the best results for the skin, especially since it contains active ingredients such as retinol and retinal. After thoroughly cleansing the face, start by applying Celimax The Real Noni Hydra Firming Lotion. Apply an appropriate amount to the face and neck to provide deep hydration, soothe the skin, strengthen the skin barrier, and prepare it to absorb the following products. Next, apply Celimax Cica Niacinamide AC Calming Serum in a small amount and gently spread it over the skin. This serum helps calm inflammation, reduce breakouts, control excess oil, and improve overall skin tone thanks to niacinamide and cica. In the evening specifically, use Celimax Retinol Shot Tightening Serum, applying a very small amount since it contains retinol that helps stimulate skin cell renewal, reduce wrinkles and fine lines, and improve skin firmness and elasticity. After that, Celimax Retinal Shot Tightening Booster can be applied, which is slightly stronger than retinol and helps enhance anti-aging results, boost skin renewal, and improve skin texture and radiance. Retinol and retinal products are best used only at night and in small amounts, and sunscreen should always be applied during the day because these ingredients increase the skin’s sensitivity to sunlight. It is usually recommended to start using them about three times per week and gradually increase the frequency depending on the skin’s tolerance.
