Hoygi 8D Hyaluronic Acid Anti-Aging Serum - 15 Vials

General information only, not medical advice. Individual results vary. If you have a skin condition, are pregnant or breastfeeding, or use prescription actives, talk to your doctor before starting any new routine.

Reverse the Look of Dehydration

Hydration is the silent accelerator of visible ageing. The Hoygi 8D Restore uses eight different molecular weights of hyaluronic acid so water is held at more than one depth, with copper peptide and fullerene handling the anti-ageing side.

Key benefits

• Eight molecular weights of hyaluronic acid - hydration that reaches multiple depths instead of only the surface
• Copper tripeptide-1 - a well-studied peptide that supports collagen synthesis and repairs micro-damaged skin
• Fullerene - a powerful antioxidant that neutralises free radicals from UV and blue light exposure
• Clinical freshness in every vial - hermetically sealed ampoules mean no oxidation and no contamination between uses

Ingredients and what they do

8D Hyaluronic Acid complex, Copper Tripeptide-1, Fullerene (C60). Vegan, fragrance-free, alcohol-free, pH balanced, non-comedogenic.

How to use

1. Twist to open a vial.
2. Warm the serum between your palms.
3. Press into the face and neck.
4. Use as a 15-day intensive reset, or one vial every other day for daily maintenance.

Who it is for

Suited to: Dry, dehydrated or mature skin, and anyone who wants an intensive hydration course rather than a permanent new step in the routine.
Not suited to: Oily skin using it daily - it is rich. Not suitable if you have a known allergy to copper peptides.

What to expect

• Day 1: skin feels plumper and immediately more hydrated.
• Day 3: the 72-hour moisture lock becomes noticeable.
• Days 1-15: a full course visibly evens tone and softens the look of fine lines.

Frequently asked questions

How do the 15 vials work?

One vial per application. That is roughly a two-week intensive course, or a month of every-other-day use.

Can I use it with other actives?

Yes. Apply after cleansing and before heavier creams. It pairs freely with niacinamide; be more cautious stacking it with retinol on the same night.

Does it really last 72 hours?

Multiple molecular weights of hyaluronic acid hold water at different depths so it does not evaporate as quickly. In very dry indoor air you may still want a cream on top.

Is it suitable for sensitive skin?

Yes - it is fragrance-free and alcohol-free, which is why it is a good choice for reactive skin.

Questions people ask us most

Is a serum in single-use vials better than a bottle?

For multi-ingredient formulas like this one, yes. Each ampoule is sealed until you open it, so the hyaluronic acid and the peptide complex are protected from air and light between uses. It also removes the guessing - you use a full session and discard the rest.

Does hyaluronic acid work on dry skin?

Yes, but only with moisture underneath it. Hyaluronic acid pulls water into the skin, so if your skin has no water to pull, applying it to dry skin can leave you feeling tighter than before. Apply it to damp skin and seal with moisturiser.

How often should I use it?

Morning and night is fine for most people. If your skin starts feeling tight or shiny very quickly, use it once a day and add a richer cream on top.

Can I use it with retinol?

Yes, but separate them. Use hyaluronic acid on damp skin, then wait a few minutes before your retinol, or use retinol at night and this serum in the morning. Our niacinamide vs retinol guide has the full layering order.
