About MEG 21 & Supplamine®
What is MEG 21?
MEG 21 is physician-dispensed anti-glycation skincare, developed by Dr. Annette Tobia, PhD. It is recommended and dispensed in physician practices and med spas, and you can shop it right here.
What is Supplamine®?
Supplamine® is our patented anti-glycation technology, and it is in our serum and our Face, Décolleté and Eye treatments. It helps interrupt glycation, the process where sugar binds to collagen and elastin and stiffens them over time. Read the science.
Why does glycation matter for skin?
Sugar reacts with collagen and elastin and forms rigid cross-links. Stiffer fibres flex less, one of several reasons skin loses firmness. Sunscreen covers UV and antioxidants cover oxidative stress; Supplamine® is there for glycation.
Which products contain Supplamine®?
Our serum and treatments: Advanced Defense Serum, Smooth Radiance Face Treatment, Décolleté Treatment Advanced Formula and Bright & Firm Eye Treatment. Daily Mineral Shield SPF 30 is your daytime protection step.
Our Daily Mineral Shield SPF 30 is pure mineral sun protection, without Supplamine®.
Is MEG 21 backed by research?
Yes. A published randomized controlled trial and eight clinical studies, all on human subjects. See the science, or email professional@meg21.com for research and references.
Using the products
What order do I apply them in?
Cleanse, then serum, then eye treatment, then your treatment cream. In the morning, finish with Daily Mineral Shield SPF 30.
How much should I use?
Less than you think: two to three drops of serum, a pea-sized amount of Face Treatment, a small amount of Eye Treatment, and a little Décolleté warmed between your fingers.
Morning, night, or both?
Serum and Eye Treatment: morning and night. Face Treatment: every morning, and at night too for normal to combination skin. Décolleté: at night, or morning and night for very dry skin. Every product page has a How to use tab.
Can I keep my retinol, vitamin C and sunscreen?
Yes. Those work on cell turnover, oxidative stress and UV. MEG 21 focuses on glycation, a separate driver of skin aging, so it adds to your routine rather than replacing anything.
Do any of the creams have SPF?
No. Sun protection comes from Daily Mineral Shield SPF 30, your last step every morning.
Not sure where to start?
Try the Anti-Glycation Discovery Kit: five travel sizes, the whole routine, before you commit to full sizes.
Results
When will I see results?
In the clinical study, results were measurable from week 2 and kept improving through week 8. Use your treatments every day and judge your skin at eight weeks.
What did the clinical study show?
In an 8-week open-label study of an original MEG 21 Supplamine® formula, conducted by a contract research organisation: skin hydration +62.9%, firmness +35.4%, area of lines & wrinkles −44.2% and superficial facial lines −50.5%. Individual results may vary.
Skin types & sensitivities
Is MEG 21 suitable for sensitive skin?
No adverse events were reported in the facial study. If your skin is very reactive, try a small amount on one area first.
Which product is best for dry skin?
Décolleté Treatment Advanced Formula, our richest cream, with the highest concentration of Supplamine®. For very dry skin, use it morning and night.
And for normal or combination skin?
Smooth Radiance Face Treatment is the lighter daily cream, made for normal to combination skin. Advanced Defense Serum suits all skin types.
Can I use the eye treatment with contact lenses?
Bright & Firm Eye Treatment is ophthalmologist-tested and suitable for contact-lens wearers. Pat a small amount along the orbital bone with your ring finger.
Where can I see the full ingredients?
On every product page, and on our Ingredients page.
Med spa treatments
Can I use MEG 21 between med spa treatments?
Yes. MEG 21 complements your treatments. Use it between treatments, once your provider says your skin is ready, and always follow their post-care instructions first.
After a peel, laser or microneedling, when can I start again?
Once your provider says your skin is ready. Your provider knows your treatment, so their timing comes first.
Where do I find MEG 21 in person?
MEG 21 is dispensed in physician practices and med spas. Ask your provider, or shop online here any time.
GLP-1
Can MEG 21 help my skin while I am on a GLP-1?
MEG 21 is cosmetic skincare. It supports skin hydration and the look of firmness, and it is not a medicine or a treatment for medication side effects.
Can I use it alongside my GLP-1 medication?
Please talk to your doctor about your medication and any changes you notice in your skin. They know you best.
Pregnancy & medical
Can I use MEG 21 while pregnant or breastfeeding?
Please ask your doctor before starting any new skincare while pregnant or breastfeeding. Every product page lists the full ingredients, so you can share them with your doctor.
I have a skin condition or use prescription skincare.
Ask your doctor or dermatologist before adding MEG 21. Our products are cosmetic skincare, not medicines.
