Description

The Glass Skin Set: the Japanese double-cleanse ritual for skin that looks lit from within

In Japan, glass skin isn't a filter. It's a habit: cleanse twice, treat once, protect. This set gives you the whole ritual in four steps that are made to work together, all powered by 5-ALA, a molecule your own skin already makes.

The Cleansing Oil melts away sunscreen, waterproof makeup and excess oil. The Cleansing Gel then washes off what's left and gently refines texture with a mild AHA complex. The Niacinamide + 5-ALA Serum targets the look of pores, uneven tone and redness. The Day Cream locks in hydration for a plump, dewy finish.

Four steps and about three minutes a day. The result is smooth, clear, luminous skin that looks like glass.

Application

Evening: the full double cleanse

Cleansing Oil: Massage 2–3 pumps onto dry skin in circular motions, then rinse with lukewarm water.
Cleansing Gel: Massage 1–2 pumps onto damp skin until it turns into a milky emulsion, then rinse and pat dry.
Niacinamide + 5-ALA Serum: Press 2–3 drops into skin, working from the center of the face outward.

Morning: fresh and protected

Cleansing Gel: 1–2 pumps on damp skin, then rinse.
Niacinamide + 5-ALA Serum: 2–3 drops. Let it absorb fully.
Day Cream: Massage in a pea-sized amount.
Finish with SPF 30+.

Where Science Meets Results

How 5-ALA Helps Your Skin Reveal Its Best Self

1. Activate Cellular Energy
As we age, our cells produce less energy - the skin can appear dull, tired, and less radiant. 5-ALA helps re-energize these natural processes, giving your skin newfound vitality and a visibly brighter look.

2. Support Skin Regeneration

With renewed energy, your skin can better support its natural repair and renewal cycles. Your complexion appears more refreshed, balanced, and restored.

3. Strengthen Skin Structure
5-ALA supports the formation of collagen and elastin, helping your skin maintain firmness - the foundation of smooth, supple skin texture.

4. Preserve Skin Hydration
Over time, the skin barrier becomes more delicate. By supporting healthy cellular metabolism, 5-ALA helps strengthen the barrier so your skin can retain moisture more effectively. The result: a nourished, protected, comfortably hydrated skin feel.

The Results Our Community Loves

Natural Glow Booster

Dull, tired-looking skin - even with a dedicated routine?

In many cases, the skin is simply lacking energy. Our active ingredient 5-ALA supports mitochondrial processes essential for cellular energy production - helping your skin regain its radiance quickly and naturally.

Refined Skin Texture

Uneven texture or enlarged pores?

This is often linked to a slowed cellular renewal process.

5-ALA supports the natural renewal cycle and helps rebalance overall skin texture - for visibly refined pores, smoother contours, and a more even-looking complexion.

Skin in Balance

Does your skin tend to flush easily or look stressed?

A slowed-down renewal process is often the reason.

Our active ingredient 5-ALA supports natural regeneration and reinforces the skin’s protective functions. As a result, redness fades, irritation calms, and your complexion looks noticeably more even.

Deep Hydration

Dry, tight skin even though you’re using rich moisturizers?

Moisture alone isn’t always enough - your skin needs support to hold on to it. Clinical studies show that 5-ALA sustainably improves the skin’s moisture levels.

The result: skin that looks plump, fresh, and deeply hydrated.

Preventive Skincare

Looking for skincare that works early and supports your skin in the long run?

We believe in preventive skincare powered by 5-ALA.

5-ALA supports cellular activity and keeps your skin’s natural renewal processes moving - for smoother, clearer-looking skin today and the confidence of knowing your complexion will stay radiant tomorrow.

Ingredients

These Ingredients Make the Difference

Niacinamide

Vitamin B3: visibly refines skin texture, strengthens the barrier, reduces redness, and regulates excess oil for a more even complexion.

Ideal for: texture refinement, barrier support, radiance

Hydrolyzed Hyaluronic Acid

A smaller-molecule form of hyaluronic acid that penetrates deeper into the skin - delivering intensive, long-lasting hydration and helping maintain moisture levels.

Ideal for: hydration boost, smoother skin

Squalane

A lightweight, skin-identical lipid derived from olives. Prevents moisture loss, improves elasticity, and delivers a silky-smooth skin feel.

Ideal for: hydration, softness

Step 1 -
Double Cleanse

Start the Japanese way. Massage the Cleansing Oil onto dry skin to melt away makeup, SPF and buildup. Then follow with the Cleansing Gel on damp skin to wash off every last trace and gently refine texture. Your skin is left fresh and soft, never tight.

Step 2 -
Treat

Press 2–3 drops of the Niacinamide + 5-ALA Serum into clean skin. 5% niacinamide visibly refines pores and evens tone, while 5-ALA brings back a fresh, energized look. This is where the glass-skin glow begins.

Step 3 -
Hydrate & Glow

Seal it all in with a pea-sized amount of Day Cream each morning. Hyaluronic acid, squalane and 5-ALA leave skin plump, dewy and smooth, ready for SPF and makeup. It's the finishing touch for skin that looks lit from within.

What is 5-ALA in skincare?

5-ALA (5-Aminolevulinic Acid) is a naturally occurring amino acid that supports cellular energy production.

Found in small amounts in foods like spinach and tomatoes, 5-ALA helps energize skin cells, making it a powerful ingredient for improving hydration, firmness, and glow.

How does 5-ALA work on the skin?

5-ALA stimulates the mitochondria, known as the "powerhouses" of cells.

This boosts the production of ATP (cellular energy), which helps the skin to generate collagen and elastin, retain moisture, and regenerate more effectively - resulting in smoother, more radiant skin.

Is 5-ALA safe for daily use?

All our 5-ALA skincare products are dermatologically tested and suitable for daily use as part of your skincare routine.

When can I expect to see visible results with 5-ALA skincare?

In a clinical study, participants saw a measurable increase in skin hydration after just 4 weeks, along with a visible reduction in wrinkle depth and fine lines. Results may vary depending on skin type and consistency of use.

Is 5-ALA a natural skincare ingredient?

Yes. 5-ALA occurs naturally in the human body and in small amounts in foods like spinach, tomatoes, and potatoes.

In skincare, it is biotechnologically derived for purity, safety, and effectiveness.

Can I combine 5-ALA with other skincare ingredients?

Absolutely. 5-ALA pairs well with hydrating agents like hyaluronic acid, barrier-supporting ingredients like ceramides, and even brightening actives like Vitamin C. It’s a versatile and gentle base for many routines.

Is there scientific research supporting the effectiveness of 5-ALA in skincare?

Yes. A Japanese double-blind clinical study confirmed that 5-ALA significantly increased skin moisture and reduced the depth of wrinkles after just four weeks of regular use.

Source: Naraoka et al., Health Journal, 2020.

Is 5-ALA vegan and cruelty-free?

Yes. The 5-ALA used in KIYOMI SKIN products is vegan, biotechnologically produced, and our skincare is never tested on animals.

What are the skincare benefits of 5-ALA?

5-ALA is ideal for anyone looking to:

  • Deep hydration and moisture retention
