Description

Four Powerful Serums for a Radiantly Beautiful Skin

Our Full Spectrum Serum Kit combines four highly effective serums for a simple skincare routine that thoroughly nourishes and regenerates your skin. Each serum is specially designed to address different skin needs – for a radiant, smooth complexion and healthy-looking skin.

Vitamin C Serum – Radiant Skin and Protection:

The Vitamin C Serum protects your skin from free radicals, supports collagen production, and promotes an even complexion. Dark spots are lightened, leaving your skin firmer and fresher.

Niacinamide Serum – For an Even Complexion:

Niacinamide reduces blemishes and redness, refines pores, and strengthens the skin barrier. It regulates sebum production and ensures a clear, balanced complexion.

Bakuchiol Serum – The Gentle Retinol Alternative:

Bakuchiol, a plant-based retinol alternative, that targets wrinkles and fine lines without irritating the skin. Its antioxidant properties protect against premature skin aging, leaving your skin smooth and supple.

Moisturizing Serum – Intensive Hydration:

This serum provides long-lasting hydration and protects your skin from drying out. With powerful ingredients like 5-ALA and collagen, it plumps the skin from within, leaving it smooth and soft to the touch.

Your Perfect Skincare Routine

The Full Spectrum Serum Kit offers everything your skin needs – hydration, anti-aging ingredients, and antioxidant protection. Each serum is formulated to support the skin’s natural regeneration processes and shield it from external influences.

After cleansing, apply 1-2 drops of the recommended serum to the face, gently massage in, and allow it to absorb. Follow up with a moisturizer and sunscreen (during the day) or just a moisturizer (in the evening).

How 5-ALA enhances skin smoothness and supports optimal cellular activity

1. More Energy for Every Skin Cell
5-ALA plays a crucial role in cellular metabolism and supports ATP production - the energy source your skin cells rely on for a healthy, radiant appearance.

2. Targeted Support for Regeneration
With this renewed energy, your cells can renew and repair more effectively - resulting in smoother, more resilient skin.

3. Strengthen Collagen
5-ALA supports processes involved in natural collagen and elastin production, helping your skin maintain firmness and elasticity.

4. Long-Lasting Hydration
By reinforcing the skin barrier, moisture is better retained - leaving skin smooth, supple, and comfortably hydrated.

5. A Visibly More Even Complexion
The result: refined, smooth skin with a fresh, radiant glow.

The Results Our Community Loves

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.

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.

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.

Ingredients

These Ingredients Make the Difference

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.

Who should use 5-ALA skincare products?

5-ALA is perfect for those looking to:
