Sensitive Skin + Over 40


Our lab tests 16 core and dozens of secondary genetic markers that contribute to skin protection and premature aging and can play a big role in your skin’s future well-being.

The genes tested are cataloged according to their structural, functional, and metabolic effects on the skin. 

Each Skin DNA category provides 1 of 3 outcomes: High Risk, Medium or Low Risk.

  • Collagen: High Risk 1-31% | Medium 32-70% | Low Risk 70-100%
  • Glycation: High Risk 1-50% | Medium 50-99% | Low Risk 100%
  • Pigmentation + UV: High Risk 1-57% | Medium 58-75% | Low Risk 76-100%
  • Antioxidant Protection: High Risk 1-56% | Medium 57-70% | Low Risk 71-100%
  • Sensitivity: High Risk 1-56% | Medium 57-69% | Low Risk 70-100%

How does your skin compare with the rest of the population?

Yudoyu’s partner lab SkinDNA® has established one of the world’s largest derma genetics databases with more than 2 million DNA profiles*.

Our data allows us to discover distinctive skin aging traits shared between groups of people.


Your Skin DNA Risk Scores

Collagen + Elasticity
Collagen Breakdown

Genetically, your body is working at a near optimum. You are producing close to normal levels of collagen to counteract the breakdown process.


COLLAGEN BREAKDOWN: Impaired – You may break down collagen faster than it is produced and be prone to skin laxity and looseness.

COLLAGEN PROTECTION: Optimal – Your body produces the antioxidant responsible for protecting collagen at an optimal level.

Wrinkling (Glucose Related)

Genetically, your body has a reduced ability to efficiently break down glucose. Excess glucose has been linked to a number of traits, amongst them – wrinkles.


WRINKLE FACTOR: Deficient – You have a minimal ability to break down glucose efficiently. Excess glucose molecules stick to collagen and elastin, resulting in cross-linked fibers that are bound together. This ultimately leads to the formation of wrinkles, thinning skin, free radicals, and structural skin damage.

Pigmentation + UV Damage

You have a higher probability to experience irregular pigmentation and burning. Your test indicates a number of vulnerabilities in the production of melanin and other processors that function to protect your skin from the sun.


MELANIN 1: Impaired – Your body is prone to irregular melanin production, causing sensitivity to sunlight.

MELANIN 2: Deficient – You are more prone to freckling, hyperpigmentation, and white spots (hypo-pigmentation). Your skin is likely to burn rather than tan.

PHOTO DEFENSE: Impaired – Your body is functioning less than optimally in breaking down free radicals produced from UVB rays. These “Burning” Rays are responsible for sunburns and pigmentation responses.

UV RADIATION REPAIR: Optimal – Your genes are excellent at repairing your skin from DNA damage caused by UVA Radiation (also known as the “Aging Rays”).

UV FREE RADICAL REPAIR: Deficient – Your genetics minimally repair damage from Free Radicals produced by the sun and UVA exposure. This gene is crucial for maintaining the overall health and integrity of skin by repairing any free radical induced damage to your DNA.

Free Radical Damage
Free Radical Damage

Superoxide Dismutase and Glutathione Antioxidant are arguably the body’s most crucial antioxidants. The higher the levels the less prone we are to the destructive effects of free radicals.




Optimally producing at least antioxidant (Glutathione) will help you efficiently breakdown free radicals and prevent unnecessary damage to skin cells. Increasing your antioxidant intake can help provide added support.

QUINONE DEFENSE: Deficient – Quinones are highly active by products that stem from pollutants such as UV radiation, car exhaust fumes, carbon and cigarette smoke. Once absorbed into the skin (if not efficiently broken down) they can begin to oxidize and cause damage within the skin’s wall. Your results suggest that your skin may be MORE sensitive to environmental pollutants.

Skin Sensitivity

Your body may be producing an oversupply of inflammatory proteins. Your results indicate that this oversupply may likely cause rashes, redness or irritation.You may also be more prone to chemical sensitivity issues from exposure to pollution, perfumes and highly active products.


INFLAMMATION: Impaired – Your body may occasionally over-respond to perceived threats, irritating skin cells and causing itching, redness, skin sensitivity, hay fever, or other allergies.

XENOBIOTIC DETOX: Impaired – Your body may not break down xenobiotic compounds such as cigarette smoke, exhaust fumes, air pollution, and alcohol as well as it should. Variations in this gene can create internal inflammation, causing redness, rashes, and acne.

SKIN SENSITIVITY: Impaired – You are likely prone to contact inflammation or irritations caused by cleaning chemicals, perfumed products, active skincare ingredients, preservatives, essential oils, and/or chemical exfoliants.

Healthier, Happier Skin is Achievable

Here is your personalized skincare plan based on your results!


Add these easy-to-do lifestyle habits to your daily routine.

  • Limit Sugar and Processed Foods: Excessive sugar consumption can lead to glycation, a process where sugar molecules attach to collagen fibers, causing them to become stiff and brittle. Limiting your intake of sugary and processed foods can help preserve collagen integrity.
  • Limit UV exposure, and use sun protection daily to reduce the incidence of irregular pigmentation and UVA skin sensitivity.
  • Avoid highly active skincare products that contain Retinols, Alpha Hydroxy Acids, and high concentrations of Vitamin C.


Look for these topical ingredients when shopping for skincare.

  • Blue Berry Extract to break down glycation bonds 
  • Linoleic Acid increases the skin’s defenses from pollution, additionally reduces skin inflammation
  • Terminalia Ferdinandiana (Kakadu Plum) Fruit Extract is a wonderful multi-tasking ingredient containing well tolerated Vitamin C.
  • Niacinamide (Vitamin B3) interrupts inflammation from UV light and inhibits melatonin


Please consult your doctor before you begin a new dietary plan.

  • Omega-3 fatty acids have anti-inflammatory properties that can help reduce inflammation in the skin and improve pigmentation issues. Include fatty fish (salmon, mackerel, sardines), flaxseeds, chia seeds, walnuts, and hemp seeds in your diet to increase your omega-3 intake.
  • Foods Rich in Vitamin C are essential for collagen production and skin repair. It also has antioxidant and anti-inflammatory properties that can help protect and soothe sensitive skin. Incorporate foods rich in vitamin C such as citrus fruits, strawberries, kiwi, bell peppers, and broccoli into your diet.
  • Foods with a low glycemic index (GI) cause a slower and more gradual increase in blood sugar levels, reducing the risk of glycation. Focus on consuming whole, unprocessed foods such as non-starchy vegetables (broccoli, cauliflower, zucchini), legumes (beans, lentils), nuts, seeds, and whole grains (quinoa, barley, oats).
  • Berries such as blueberries, strawberries, raspberries, and blackberries are rich in antioxidants, particularly vitamin C and flavonoids. These antioxidants help neutralize free radicals and protect the skin from oxidative damage.


These minimally-invasive professional treatments will benefit your skin’s texture and make you glow!

  • Oxygen facials involve the application of pressurized oxygen infused with a serum containing vitamins, antioxidants, and botanical extracts to the skin. This treatment helps hydrate, revitalize, and nourish sensitive skin without causing irritation or discomfort.
  • LED light therapy uses specific wavelengths of light to penetrate the skin and stimulate cellular activity, promoting healing, rejuvenation, and overall skin health. This non-invasive treatment is gentle and well-tolerated by sensitive skin, helping to reduce inflammation and promote a healthy complexion.
  • Platelet-Rich Plasma (PRP) Therapy isolates platelet-rich plasma containing growth factors, and injecting it into the skin or applying it topically during microneedling. PRP stimulates collagen production, accelerates tissue repair, and enhances overall skin rejuvenation.

Your DIY At-Home Treatments and Tools

Selected for you!

Facial Massage

Smooth wrinkling and chase away free radicals!

Lymphatic Facial Massage MapLymphatic drainage is a facial massage to boost the body’s natural draining system. The face is left visibly more lifted, firm, and youthful by assisting in the movement of excess toxins, water, fats, and proteins down the lymph vessels and into the nodes!

Step 1: Apply treatment oil or cleansing balm of choice. Fingers should not drag but glide easily over the skin with little to no resistance.

Step 2: Follow the directional guide demonstrated in the illustration. Using light pressure, gently massage the face upwards and outwardly. Pressure should be not unlike moving a pen across a table. The key is to lift and relax muscles! If redness occurs, lighten the pressure.

Step 3: Finish with a glass of water, herbal tea, or warm broth for added hydration.


What if I’m doing this wrong?

If you are working in upward and outward motions with light, relaxing amounts of pressure, you are certain to fight against one of the main causes of wrinkles – gravity.

Devices & Tools

Best for Sensitive Skin, Hyperpigmentation, Wrinkles

Cooling facial rollers or globes made of materials such as jade or rose quartz can help soothe and calm sensitive skin. Keep them in the refrigerator before use to enhance their cooling effect and reduce redness and inflammation.
Dermaplaning tools use a small blade to remove dead skin cells and vellus hair (peach fuzz) from the skin’s surface, resulting in smoother, brighter skin. This treatment can improve product absorption and enhance the effectiveness of skincare products.
Microcurrent devices with adjustable intensity levels allow you to customize the treatment to suit your skin’s sensitivity. They can help lift and firm the skin, reduce fine lines and wrinkles, and improve circulation without causing discomfort.
