How to Use

Simple Application Steps

Incorporate this essence into your daily routine with a simple, effective application method designed to maximize its multi-weight hyaluronic acid benefits for lasting hydration and comfort.

Apply to Damp Skin

After cleansing and applying toner, while your skin is still slightly damp, dispense 2-3 drops of the essence into your palms. The damp skin helps the hyaluronic acid bind moisture more effectively.

Press and Pat Gently

Gently press and pat the essence into your face and neck using your fingertips. Avoid rubbing, as patting helps the formula absorb better without pulling on sensitive skin. Ensure even coverage.

Layer Moisturizer On Top

Allow the essence to absorb for a moment, then follow with your usual serum, moisturizer, or sunscreen. This seals in the multi-layer hydration provided by the 8 types of hyaluronic acid.

I am absolutely in love with this product. It doesn't leave the skin sticky, it absorbs immediately and, very important, it doesn't peel off if you put an oil serum over it. It's really rare that I love a skincare product so much that I buy it more than once like I did for this one.

I have the driest skin but this stuff really hydrates and I am looking super moisturized in the morning. I usually apply at night and combine it with a tiny bit of retinol serum, or even just rose water and that's it. I still love it.

The texture of this serum is fantastic. It goes on very smoothly without feeling heavy or greasy at all, and absorbs quickly into the skin. My skin has never felt this hydrated throughout the day, even in dry weather.

I've tried many different skincare products, but this one has been a game changer for my dry skin. It feels so light yet provides intense hydration, and I have noticed a significant improvement in the overall texture of my skin. It doesn't leave any sticky residue.

This Hyaluronic Acid serum is excellent for those of us with dehydrated skin. I've used it after my toner and before my moisturizer, and my skin has stayed hydrated and plumped all day long. I feel it works best at night, allowing the moisture to seep in.

Common Questions Answered

Explore answers to common questions about incorporating this essence into your routine, its compatibility with other products, and its suitability for various skin concerns. We provide clear, factual guidance to help you decide if this hydrator is right for your needs.

How should I use the Hyaluronic Acid Water Essence in my skincare routine?

This essence is designed to be versatile. Its lightweight, fast-absorbing formula layers well under moisturizers and sunscreens. You can also mix a drop with your foundation for added hydration. For best results, apply to slightly damp skin after cleansing and toning.

Is this essence suitable for sensitive or easily irritated skin?

Yes, it is formulated with sensitive skin in mind. The product has completed a skin irritation test and is clinically proven to be non-irritating. It is fragrance-free and unscented, minimizing the risk of irritation for reactive skin.

What makes the 8 types of hyaluronic acid special compared to regular ones?

The key difference is the multi-molecular weight complex. Using 8 types of hyaluronic acid allows the formula to hydrate at various skin layers, providing both surface moisture and deeper, longer-lasting hydration compared to single-weight formulas.

Can I use this essence every day, and how often should I apply it?

It can be used both morning and evening. In the morning, it provides a hydrated base for makeup. At night, it helps replenish moisture lost during the day. Adjust the amount based on your skin’s needs and the climate.

Can I use this essence with other active ingredients like retinol or vitamin C?

While the essence focuses on hydration, you can layer other active serums like niacinamide or retinol over it. However, we recommend introducing new actives slowly and patch testing to ensure compatibility with your sensitive skin barrier.

Is this product only for the face, or can it be used on other body areas?

This essence is specifically designed for the face. Its formula is optimized for facial skin’s needs and texture. We do not recommend using facial skincare products on other body areas unless the product label specifically states it is suitable for body use.
