Hydrated skin needs two things: a strong outer barrier that keeps water in, and a deeper layer that can hold it. Ceramides reinforce the surface seal, while hyaluronic acid helps the inner layer retain water.
BOOST provides inside-out support to work alongside your moisturizer and SPF, helping hydration last longer through the day.

When the skin barrier thins or becomes disrupted, water escapes more quickly and irritants get in. Dry indoor air, frequent flying, harsh cleansers, very hot showers, and age all nudge the barrier in the wrong direction.
You feel this as tightness, rough texture, increased sensitivity, or skin that looks dull despite regular moisturizing. Strengthening the barrier while improving the skin’s ability to hold water is the most reliable way to keep hydration steady, not just temporarily boosted.
Think of skin as a coat and a sponge.
The outer “coat” is made of flattened cells set in a lipid “mortar,” rich in ceramides, cholesterol, and fatty acids. When this coat is intact, water evaporates more slowly and the skin is less reactive.
Beneath it, the living layer behaves like a sponge. It needs water-binding molecules, such as hyaluronic acid, and good circulation to feel supple rather than tight.
Ceramides help maintain the coat’s seal.
Hyaluronic acid helps the sponge hold water.
Seal plus hold is what creates lasting comfort.
Topicals are essential, but they work mainly at the surface and can struggle in very dry air.
Applying hyaluronic acid on damp skin and sealing it with a ceramide moisturizer slows water loss, yet results often fade after an hour or two if the deeper layers lack the raw materials to retain water.
Inside-out support complements this approach. Oral ceramides help maintain barrier lipids so the surface loses less water throughout the day. Oral hyaluronic acid supports the water-binding environment deeper in the skin.
BOOST combines both, giving your topical routine a stronger foundation rather than trying to replace it.
Hyaluronic acid needs water to work. Applying it to dry skin can actually make skin feel tighter, so always apply it to damp skin and seal with a moisturizer.
Over-cleansing or using alkaline soap bars strips lipids and increases water loss. Stick to pH-balanced cleansers.
Very hot showers spike evaporation. Warm is better.
In low-humidity environments such as winter heating or airplanes, use a humidifier when possible and keep the barrier well sealed. Small adjustments like these stabilize comfort without complicating your routine.
Morning
Rinse or cleanse gently if needed
Apply hyaluronic acid serum to damp skin
Seal with a ceramide moisturizer
Apply SPF 30+
Take BOOST with breakfast
Evening
Cleanse properly
Apply hyaluronic acid to damp skin
Reapply a barrier-friendly moisturizer
Buffer strong actives with it if your skin is sensitive
Environment
Use a humidifier when indoor humidity drops below ~40 percent
Keep showers warm rather than hot
Avoid harsh, high-foam cleansers
Most people notice more comfortable, less reactive skin within two to four weeks of consistent use. Texture and bounce typically build across eight to twelve weeks.
Does BOOST include ceramides and hyaluronic acid?
Yes. BOOST contains oral ceramides to support the skin barrier and hyaluronic acid to help maintain the inner water reservoir. The combination is designed to complement your moisturizer and SPF.
How long does it take to notice a difference?
Comfort often improves within two to four weeks when BOOST is paired with a consistent topical routine. Improvements in smoothness and elasticity typically build across eight to twelve weeks.
Do I still need my moisturizer if I take BOOST?
Yes. BOOST works from the inside while moisturizers work on the surface. Using both provides more dependable hydration, especially in dry air or during travel.
Topical ceramides and hyaluronic acid help seal and smooth the surface. But lasting hydration depends on what’s happening in the living layers beneath the skin.
BOOST supports skin hydration from within by providing oral ceramides to reinforce the barrier and hyaluronic acid to support the skin’s deeper water-holding capacity. Used consistently alongside your moisturizer and SPF, it helps hydration feel steadier, not temporary.
