- Peptides and Voluform™: Targets structural support helping to tighten, lift, and rebuild facial contours, particularly in areas prone to sagging like the cheeks and jawline.
- Antioxidants including 3-O-Ethyl Ascorbic Acid and Coenzyme Q10: Helps to brighten the skin, even tone, and protect against environmental damage enhancing overall radiance and resilience.
FACETIGHT™ SERUM:
- Sesaflash®: Instantly tightens and smooths the skin with a sesame-derived active. Provides an immediate lifting effect and long-lasting hydration - ideal for fine lines and tired skin.
- Inyline®: A neuropeptide that targets expression lines. Helps relax facial tension, softening wrinkles - often called a "botox-like" peptide without needles.
- Argassential™: An active from Moroccan argan leaves that boosts skin volume. Firms and plumps the skin by enhancing lipid storage and dermal density - ideal for loss of firmness and thinning skin

Why all three
One protocol, three steps
Step 1 · FACETIGHT™ Serum
The serum tightens
A lightweight peptide serum, our facelift in a bottle. It tightens and smooths the look of skin, boosts elasticity and refreshes tired-looking skin, and gives the SDL TIGHTEN BOOST™ the base it glides over for Modes 2 to 5.
Step 2 · FACETIGHT™ Crème
The crème lifts
Our No. 1 global bestseller, for eyes, face, neck and body. Deeply hydrating, it instantly tightens and smooths the look of fine lines, lifts the look of skin and leaves a light-reflecting glow.
Step 3 · SDL TIGHTEN BOOST™
The device elevates
The first at-home device engineered to lift sagging skin and target midface volume loss. Five modes work across the surface, dermal and neuromuscular layers, in 5 minutes or a 30-minute full protocol.
No needles. No downtime.
SDL TIGHTEN BOOST™, simply put
Your questions, answered
*Independent user perception trial of SDL TIGHTEN BOOST™, single 30-minute full-protocol treatment. Individual results vary.
The protocol
Five modes. One tightening protocol.
Built to mirror the sequence of Fatma Shaheen’s signature SDL FACELIFT, every mode is designed around one result: tighter, lifted skin.
Use any mode on its own for a targeted boost. For the best results, follow all five in order.
Mode 1 · Blue LED 417 nm
Meso: prep for the heat
Needle-free electrical pulses + blue LED
Needle-free electrical pulses and blue LED reduce surface resistance by up to 1,000x, opening the path for RF to reach where it’s needed most. 94% agreed their skin texture looked smoother and pores more refined.
Use on clean, dry skin. No product applied.
Why your skin needs blue light
Blue light works at the surface. It helps refine texture and the look of pores, priming skin for the modes that follow.
Mode 2 · The hero · Red LED 633 nm
Tighten: the hero
4 MHz RF + EMS + red LED
The heart of the system. A clinical-grade, high-stability 4 MHz RF engine, paired with EMS and red LED, fires deep into the prepared skin. It delivers instant tightening in 5 minutes while awakening the Type I collagen behind a lasting, structural lift across the jawline, jowls, cheeks and neck.
Apply FACETIGHT™ Serum or Crème first.
Why your skin needs red light
Red light reaches deeper than other visible light. It supports the skin’s natural collagen renewal, helping skin look firmer and plumper over time.
Mode 3 · Yellow LED 590 nm
Booster: fuel the firmness
Electroporation + yellow LED
Electroporation and yellow LED drive FACETIGHT™ Serum deeper, increasing active ingredient delivery by up to 400% and amplifying the firming result.
Apply FACETIGHT™ Serum or Crème first.
Why your skin needs yellow light
Yellow light is calming and brightening. It helps soften the look of redness and boosts radiance while actives are driven deeper.
Mode 4 · Green LED 521 nm
Elasticity: reinforce the rebound
Microcurrent + green LED
Microcurrent and green LED support tone and resilience, helping skin hold its tightened shape.
Apply FACETIGHT™ Serum or Crème first.
Why your skin needs green light
Green light helps balance and even the look of skin tone for a clearer, more uniform complexion.
Mode 5
Lift: sculpt the contour
3D EMS rollers · mechanical + electrical
3D EMS rollers knead and define the jawline and neck, sharpening the lifted profile.
Roll upwards and outwards over face, neck and décolletage.
Why 3D EMS rollers
The rollers knead while EMS works the facial muscles, helping drain puffiness and sharpen the jawline and neck.

Frequently asked questions
THE BUNDLE
What’s in the SDL TIGHTEN BOOST™ bundle?
The full-size SDL TIGHTEN BOOST™ device, FACETIGHT™ Serum (30 ml) and FACETIGHT™ Crème (50 ml). Everything you need for the full protocol. The bundle ships as three individual products.
Why buy the bundle rather than the device on its own?
Modes 2 to 5 need product on the skin. FACETIGHT™ Serum and Crème are what the SDL TIGHTEN BOOST™ is designed to glide over, so the bundle gives you everything for the full protocol from day one, and you save 15% on buying all three separately.
How long is the Black Friday price on?
Until 30 November at 23:59 GMT, or while stock lasts.
Can I use a discount code on the bundle?
The bundle is already discounted, so it can’t be combined with other codes.
Using it
What order do I use them in?
Cleanse, then run Mode 1 on clean, dry skin. Apply FACETIGHT™ Serum, then FACETIGHT™ Crème, then glide Modes 2 to 5 over both.
How often should I use it?
For optimal results, use the full Dermal Matrix Protocol two to three times a week.
Can I use the modes on their own?
Yes. Any mode can be used on its own for a targeted boost. For the best results, follow all five modes in order as the full protocol.
Can I use the serum and crème without the device?
Yes. FACETIGHT™ Serum and Crème are your everyday essentials, morning and evening. Use the SDL TIGHTEN BOOST™ over them whenever you treat.
When will I see results?
Many clients see a visible lift after the first session, with results building over time. Results vary from person to person.
Can I use it on my body?
Yes. It can be used on the face, neck, décolletage and body.
What shouldn’t I use with it?
Avoid oil-based products. For Modes 2 to 5, use FACETIGHT™ Serum or Crème.
How long will the serum and crème last?
It depends on how often you use them. With the SDL TIGHTEN BOOST™ you’ll use more, as Modes 2 to 5 need serum or crème on the skin.
So you never run out, choose Replenishment on the FACETIGHT™ Serum and Crème pages, select your desired frequency and save 15% on every order. You can change or pause your deliveries at any time.
