What Is the Skin1004 Tone Brightening Ampoule?

Ampoules are like supercharged serums, designed to target specific skin concerns with concentrated ingredients. The Skin1004 Tone Brightening Ampoule features MadeWhite™ technology, formulated to hydrate, soothe, and brighten—all in one step. What makes it stand out is how gentle yet effective it is, making it a great option for sensitive skin types.

Key Ingredients and Benefits

Hydrating and Soothing

Centella Asiatica is quickly becoming one of my favourite skincare ingredients. It’s famous for its skin-soothing properties and this ampoule contains a whopping 77%, making it a great choice for those with sensitive or easily irritated skin. Combined with hydrating humectants like glycerin, butylene glycol, betaine and madecassoside, it helps keep skin plump and comfortable throughout the day.

Brightening

Niacinamide is a powerhouse ingredient for improving skin tone and boosting brightness. Studies have shown that products with 2-5% niacinamide can effectively reduce hyperpigmentation¹. The Skin1004 ampoule contains 4% which combined with the hydrating ingredients mentioned above should offer a gentle, slow and steady glow.

Additionally, it contains tranexamic acid and a stable vitamin C derivative, which work together to enhance its brightening effects and promote a more even complexion.

First Impressions & Texture

The ampoule has a light, watery texture that absorbs almost instantly. It’s non-sticky, making it perfect for morning and evening use. There is no strong fragrance and it feels really comfortable on the skin.

Performance & Results

I’ve been using this ampoule for a few months, and while it doesn’t deliver an instant transformation, the hydration boost was noticeable from the very first use. My skin feels softer, smoother, and stays comfortably hydrated throughout the day, especially when layered under moisturiser.

The brightening effects, however, are more gradual. Over time, I’ve noticed a subtle but definite improvement in overall radiance, with my complexion appearing more even-toned and less dull. If you’re looking for a dramatic brightening effect, a vitamin C serum might be a better choice. However, if you have sensitive skin or already have a lot of active ingredients in your routine this ampoule’s gentle, hydrating formula offers a slow and steady glow without irritation.

Since adding this product to my routine, I’ve been able to increase the strength of my tretinoin. While I can’t attribute this solely to the Skin1004 ampoule, it has certainly helped—alongside other products like the Byoma Barrier Repair Treatment—to strengthen my skin barrier and minimise irritation.

Who It’s Best For

• Those looking for hydration + mild brightening
• People with sensitive or easily irritated skin
• Those who already use active ingredients (e.g., retinol) and need a gentle brightening product

Who Might Not Like It

If you want fast, intense brightening, a higher-strength vitamin C serum might be a better choice. Consider a targeted treatment with higher niacinamide or tranexamic acid concentrations for stubborn dark spots.

How to Use the Skin 1004 Brightening Ampoule

This ampoule can be used morning and night, but I prefer it in my morning routine for an extra boost of hydration.

1. Cleanse & Tone – Start with a clean face.
2. Apply the Ampoule – Use 2-3 drops and gently pat it into your skin.
3. Follow with Moisturiser – Lock in hydration with your usual cream.
4. Sunscreen in the AM – Essential for protecting your skin and maintaining brightness.

It layers beautifully with other skincare products, so you can easily pair it with your favourite serums and treatments.

Where to Buy

The Skin 1004 Tone Brightening Ampoule is available at several online retailers. The price varies a lot depending on where you buy it but the RRP is $24/£19. With 100ml of product, it lasts far longer than standard 30ml serums, making it great value for money. You can get an extra 5% off through my YesStyle affiliate link.

Final Verdict: Is It Worth Buying?

⭐ Rating: 8/10 ⭐
If hydration is your main focus but you’d also like a subtle brightening boost, the Skin1004 Tone Brightening Ampoule is a great option. It keeps skin plump and comfortable while gradually enhancing tone and radiance—without any harsh side effects. Based on its hydrating power alone, I’d rate it a 10/10. However, as a tone-brightening product, the effect is a bit too gentle to earn full marks.

Best for:
✔ Those who prefer gentle, steady results
✔ People with sensitive skin

Not for:
❌ Those looking for fast, dramatic brightening

Would I repurchase? YES, especially for hydration + mild radiance boost! However, I have a feeling it will take me about a year to get through the massive 100ml bottle!!!
