Discover BYOSOMWhat is DNA-based skincare?
DNA-based skincare is skincare formulated from your genetic profile instead of from a questionnaire. BYOSOM reads 12 skin-aging genes from an at-home cheek swab, including MMP1 and MMP3 (collagen breakdown), SOD2 and GPX1 (antioxidant defense), AQP3 (hydration and barrier) and COL1A1 (collagen production), in a CLIA-certified US laboratory. You get 6 personal skin reports 14–21 days after the lab receives your sample, and a face serum and face cream are formulated from your results.
Genetics account for about 60% of how skin ages, according to twin studies; lifestyle and environment make up the rest. In a 4-week independent study by GBA Polska, the BYOSOM serum and cream raised skin hydration by 28%, firmness by 11% and smoothness by 13%, and reduced wrinkle depth by 8%. The DNA skin analysis starts at $249.
How DNA-based skincare compares
| BYOSOM (DNA-based) | Quiz or photo-based brands e.g. Proven, Curology | DNA test-only kits | |
|---|---|---|---|
| Based on | Your DNA: 12 skin-aging genes | Your answers and photos of today's skin | Your DNA |
| What you get | Skin reports + a serum and cream formulated from your results | A formula chosen or adjusted from your answers | A report only, no product |
| Lab analysis | CLIA-certified US lab | No lab test | Varies by provider |
| Changes over time? | Your genes don't change, so the base stays accurate | Re-taken as your skin or answers change | One-time result |
Clinical results: GBA Polska, an independent accredited laboratory, report F/43272/01/26 (Corneometer, Cutometer, Visioscan, Visioline). Results are group averages; individual results vary. BYOSOM products are cosmetics and do not diagnose or treat disease.

The future of beauty is not louder formulas or longer routines. It is precision.
For decades, that was the only workable model. Without access to individual biological insight, approximation was efficiency.
But biology has always resisted simplification. Two people of the same age, following identical routines, experience entirely different outcomes — not because one made better choices, but because their biology is fundamentally different.
BYOSOM exists because precision is finally possible. Not louder formulas. Not longer routines. Just skincare that listens to your biology before it acts.

Frequently Asked Questions
DNA testing for skincare analyzes specific genetic variants (called SNPs - Single Nucleotide Polymorphisms) that influence how your skin functions.
We examine genes that control collagen production, antioxidant processing, hydration levels, and inflammatory responses. This genetic information allows us to create personalized skincare formulations that work optimally with your unique biology rather than against it.
Most "personalized" skincare companies use questionnaires about your current skin condition or simple skin type assessments.
BYOSOM analyzes your actual DNA - the permanent genetic blueprint that determines how your skin ages, processes ingredients, and responds to environmental factors. This means our recommendations are based on your biological reality, not temporary surface conditions.
We analyze key genes that control your skin's fundamental functions:
- MMP1 and MMP3: Control collagen breakdown rates
- SOD2 and GPX1: Manage antioxidant defense systems
- AQP3: Regulates skin hydration and barrier function
- COL1A1: Influences collagen production
- NQO1 and CAT: Additional antioxidant processing genes
These genes directly impact how your skin ages and how it responds to various skincare ingredients.
Your sample is processed in a CLIA-certified US laboratory using validated genotyping technology — the same platforms used by pharmaceutical companies and major research institutions.
Our CLIA-certified partner laboratory maintains >99% accuracy rates for genetic variant detection.
However, it's important to understand that genetics represent approximately 60% of your skin's aging process, with lifestyle and environmental factors accounting for the remaining 40%.
We provide a simple at-home collection kit with detailed instructions. The process involves:
- Cheek swab collection: Use the provided sterile swabs to collect cells from inside your cheek
- No preparation required: Unlike some tests, you don't need to avoid eating or drinking beforehand
- Quick and painless: Collection takes less than 2 minutes
- Secure packaging: Use the prepaid envelope to send your sample to our lab
Yes, completely. The collection kit includes:
- Sterile, medical-grade swabs
- Individually sealed packaging
- Clear, step-by-step instructions
- Contamination-proof sample containers
- Prepaid, tamper-evident return packaging
The process is non-invasive and poses no health risks.
We provide backup swabs in every kit. If you're concerned about collection quality, contact our customer support team immediately. We can provide guidance or send a replacement kit at no additional cost.
Our lab will also contact you if your sample quality is insufficient for analysis.
Our typical timeline is:
- Sample processing: 3–5 business days after lab receipt
- DNA analysis: 7–10 business days
- Report generation: 2–3 business days
- Total time: 14–21 business days from when we receive your sample
You'll receive tracking updates throughout the process via email and our secure online portal.
