Your skin would choose Niacinamide

Niacinamide, also known as Vitamin B3, is a true all-rounder in skincare. It improves the natural appearance of the skin by:

Reducing redness
Evening out the complexion
Refining the skin texture

Additionally, niacinamide helps to strengthen the skin barrier and protects against moisture loss.

Combined with 5-ALA and hyaluronic acid, our Niacinamide Serum provides targeted hydration, leaving the skin plump and healthy. Plant extracts and argan oil enhance the antioxidant effect, protecting the skin from harmful environmental stressors.

Refines the complexion and strengthens the skin barrier

Our Niacinamide Serum is ideal for daily use. It revitalizes tired skin, reduces irregularities, and promotes an even skin tone, so your skin shines – fresher, smoother, and healthier.

Application

Apply the KIYOMI SKIN Niacinamide Serum as needed, both
in the morning and in the evening. Use the pipette to apply 2-3 drops of the serum to your face and gently massage it in circular motions from the center of your face outwards. Allow it to fully absorb. Follow with a moisturizer.

Where Science Meets Results

How 5-ALA supports your skin’s natural functions

1. Activate Cellular Energy
5-ALA supports your skin’s natural energy production — forming the foundation for a healthy, radiant complexion.

2. Boost Regeneration
With increased cellular energy, the skin can better support its natural renewal and repair processes.

3. Strengthen Skin Structure
5-ALA helps promote the formation of collagen and elastin — for improved firmness and smoother-looking skin.

4. Maintain Hydration
A healthy cellular metabolism reinforces the skin barrier, helping it retain moisture and stay protected from dryness.

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.

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.

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.

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.

FAQs

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
Visible reduction in fine lines and wrinkles
Improved skin elasticity and firmness
Supports cell renewal and repair
Long-term radiance and skin resilience

Is 5-ALA safe for all skin types?

Yes. 5-ALA is dermatologically tested and considered safe for all skin types, including sensitive skin.

At KIYOMI SKIN, we formulate with clean, biocompatible ingredients to ensure high tolerance and daily use.
