Quick answer: choose between the 1.5% hyaluronic acid face serum for smoother hydration and fast absorption, and the 2.5% HA eye serum with caffeine and niacinamide for comfort around the eyes. You’ll find face serum options in 30 ml bottles with noticeable results within one week, and others in 15 ml bottles that may be convenient for trying it out or for travel. The eye serum is also available in a 20 ml size for noticeable results within two weeks. Choose based on your goal—hydrating your skin against signs of aging and improving the look of smaller-looking eyes.

The most complex component here is how hyaluronic acid is distributed across different molecular weights. Formulas containing Macro Hyaluronic Acid and Micro Hyaluronic Acid provide immediate surface hydration and deeper nourishment over time, helping skin look fuller and feel firmer gradually. Some formulas that promise fast results focus on reducing lines over a week, while using multiple molecular weights helps balance effective hydration with quick absorption—without a greasy feel.

If you’re looking for comprehensive face hydration and quick results, choose the face serum with the right HA concentration, which promises plumpness and flexibility within one week. If you focus on the eye area and want fewer fine lines around the eyes, choose the nourishing eye serum with a higher HA concentration and additional ingredients like caffeine and niacinamide. Its goal is to help reduce the look of puffiness and dark circles and to prep the skin around the eyes within two weeks.

Always do a simple patch test on an area that isn’t visible for 24 hours before using it fully to avoid irritation. Apply the serum after cleansing and before your moisturizer, then use sunscreen in the daytime. Avoid applying the face serum directly near the eyes if you have sensitivity. For the eye serum, keep it away from the deeper eye area. It can be mixed with light, refreshing moisturizers, but avoid overusing harsh treatments at the same time.

Based on the stated results, you can expect noticeable plumping in the skin within one week with the 1.5% HA face serum. For the eye area, you can expect a reduction in lines within two weeks with the 2.5% HA eye serum. In certain cases, higher-HA formulas can reduce wrinkle appearance by up to 40% within four weeks, plus some formulas are noted for a non-greasy feel and fast absorption.

If you’d like to try it for a shorter period, choose the 30 ml face serum bottle, which promises noticeable results within one week. The 15 ml bottle may be a good option for matching formulas during a trial or for travel. For eye-area use, choose the 20 ml eye serum for intensive hydration with extra properties like caffeine and niacinamide.
