FRACTIONAL NON-ABLATIVE LASERS: FRAX 1550 vs FRAX 1940

Both Frax 1550 and Frax 1940 are non-ablative fractional lasers, meaning they deliver controlled laser energy into the skin without removing the top layer. They promote collagen remodeling, skin resurfacing, and texture improvement — but they differ in depth and target conditions.

FRAX 1550

Indications:

  • Fine lines and wrinkles

  • Acne scars and other textural scars

  • Stretch marks

  • Large pores

  • Skin resurfacing (face, neck, chest)

  • Uneven skin texture and tone

  • Mild skin laxity

How it works:

Frax 1550 delivers non-ablative 1550 nm laser energy deep into the dermis. It creates controlled thermal injury zones to stimulate collagen and elastin production, promoting skin renewal from within.

Benefits:

  • Deep collagen stimulation

  • Smoother skin texture

  • Reduced appearance of scars and stretch marks

  • Minimal downtime

  • Safe for multiple skin types

  • Can be customized by depth and density

Results:

  • Visible improvement typically after 3–4 treatments spaced 3–4 weeks apart

  • Continued collagen production for months after treatment

  • Skin feels firmer, smoother, and rejuvenated

  • Downtime: Mild redness and swelling for 1–3 days

FRAX 1940

Indications:

  • Sun-damaged skin

  • Actinic keratoses (precancerous spots)

  • Age spots / pigmentation

  • Fine lines on surface

  • Crepey texture on face, neck, décolletage, or hands

How it works:

Frax 1940 uses a 1940 nm wavelength that targets the epidermal and upper dermal layers. It’s ideal for superficial resurfacing, improving skin clarity and pigmentation with precision.

Benefits:

  • Gentle resurfacing with minimal discomfort

  • Brightens and evens skin tone

  • Smooths superficial lines and texture

  • Improves sun damage and pigmentation

  • Excellent for treating neck, chest, and hands

Results:

  • Noticeable results after just 1–2 sessions

  • Best when done in a series of 2–3 treatments

  • Downtime: Mild flaking or redness for 2–4 days

  • Skin appears brighter and more youthful

 

Can They Be Combined?

Yes! Frax 1550 and 1940 are often combined in a single session for comprehensive skin rejuvenation — improving both deep textural issues and surface pigmentation.

How Laser Skin Resurfacing Works:

The laser delivers concentrated beams of light that target skin imperfections, either by ablating the outer skin layers (ablative lasers) or stimulating collagen growth beneath the surface (non-ablative lasers). 

What Laser Skin Resurfacing Treats:

Effectively treats a wide range of skin imperfections, including fine lines, wrinkles, acne scars, sun damage, enlarged pores, and uneven skin tone or texture. This advanced treatment is ideal for those looking to safely rejuvenate their complexion without invasive surgery.

Laser Skin Resurfacing FAQ's

What is laser skin resurfacing?

Laser skin resurfacing is a non-surgical treatment that uses laser energy to remove damaged skin layers, stimulate collagen production, and reveal smoother, younger-looking skin.

This treatment is effective for reducing fine lines and wrinkles, acne scars, sun damage, age spots, enlarged pores, and uneven skin tone and texture.

Most clients describe the sensation as a warm, tingling feeling. We apply a topical numbing cream beforehand to ensure comfort throughout the treatment.

Recovery can vary based on the depth of the treatment. Light resurfacing may have 1–3 days of redness, while deeper treatments may require up to 7–10 days of healing.

Many clients see noticeable results after just one session, but a series of treatments may be recommended for deeper wrinkles or significant skin damage.

While effective for many skin tones, certain laser types may not be ideal for deeper skin tones. At 4EvaGlow, we customize your treatment based on your skin type and goals to ensure safe, effective results.

You may notice improvement within a week, with continued collagen production and skin renewal over the next 4–6 weeks for smoother, firmer, more radiant skin.

FRAX 1550 targets deeper layers of the skin (dermis) for collagen stimulation and skin remodeling, while FRAX 1940 focuses on the superficial layers (epidermis) to improve surface texture, tone, and pigmentation. Both treatments can be combined for comprehensive skin rejuvenation.

Both FRAX treatments are well-tolerated. A topical numbing cream is typically applied beforehand. You may feel a warm or prickling sensation, but discomfort is minimal.

  • FRAX 1550: Expect redness and mild swelling for 3–5 days. Flaking may occur as the skin renews.

  • FRAX 1940: Typically results in 1–3 days of mild redness or peeling, similar to a light sunburn.

For best results, a series of 3–5 sessions spaced 4–6 weeks apart is often recommended. Your provider will customize a plan based on your goals and skin condition.

  • FRAX 1550: Improvements in skin texture and collagen production can be seen within 2–4 weeks and continue to develop over 3–6 months.

  • FRAX 1940: Results like smoother texture and brighter skin tone often appear within 7–10 days.

Yes! Combining both allows deeper and surface-level rejuvenation in a single treatment. This is often recommended for clients looking for maximum results in overall skin texture and tone.

FRAX treatments are generally safe for most skin types, but suitability depends on your individual skin tone, sensitivity, and medical history. A consultation is essential to determine the best option for you.

You may be a great candidate if you’re experiencing:

  • Early signs of aging

  • Acne scarring or textural irregularities

  • Pigmentation or sun damage

  • Loss of skin firmness

With proper skincare and sun protection, results from FRAX treatments can last 6–12 months or longer. Maintenance treatments may be recommended yearly.
