# Bio-sunscreens (melanin & DNA-repair enzymes)

Sunscreen actives built on biology rather than mineral filters — photolyase DNA-repair enzymes (ISDIN Eryfotona DNA Repairomes, Neova), mycosporine-like amino acids from algae (Givaudan Active Beauty, Mibelle), and the Polypodium leucotomos Fernblock photoprotectant (Cantabria Labs Heliocare).

## Overview and value chain

Markers: [EC: US sunscreens are OTC drugs (FDA monograph) & EU Cosmetics Regulation 1223/2009 | OECD: Industrial biotechnology | Regulator: FDA (USA), REACH (EU), NMPA (China)]

Bio-sunscreens use biological actives — DNA-repair enzymes, algal
mycosporine-like amino acids (MAAs) and biosynthetic melanin — alongside or
in place of mineral and chemical UV filters, so the product does not just
block photons but actively repairs and absorbs UV damage. Two consumer
brands anchor the enzyme line: ISDIN's Eryfotona Actinica SPF 50+, whose
"DNA Repairomes" deliver photolyase that splits UV-induced pyrimidine
dimers, and Neova's DNA Repair line, built on patented photolyase enzymes
backed by over 20 years of clinical evidence. The MAA frontier is supplied
by B2B marine-biotech houses — Givaudan Active Beauty's algae-based actives
and Mibelle's mycosporine-like amino acids green-extracted from Nostoc
cyanobacteria — while Cantabria Labs' Heliocare carries the Polypodium
leucotomos Fernblock botanical photoprotectant. Three biological UV-defense
mechanisms define the segment: photolyase photoreactivation, MAA absorption
and botanical polyphenol quenching.

The key directions of bio-sunscreens are:
1. **Photolyase DNA-repair enzymes:** blue-light-activated enzymes that
   repair UV-induced DNA damage — ISDIN DNA Repairomes, Neova.
2. **Mycosporine-like amino acids (MAAs):** algal/cyanobacterial UV-
   absorbing compounds (e.g. from Nostoc) supplied as B2B actives —
   Givaudan Active Beauty, Mibelle.
3. **Biosynthetic / fermented melanin:** microbiologically produced melanin
   as a broadband biological UV absorber (research frontier).
4. **Botanical photoprotectants:** plant-extract actives with documented
   photoprotection — Cantabria Labs' Polypodium leucotomos Fernblock.

### Value chain levels

| Level | Description | Key inputs/outputs |
|:---|:---|:---|
| **Bio-active sourcing** | source photolyase, MAAs, fern or melanin feedstock | **In:** plankton, cyanobacteria, fern, fermenter. **Out:** raw biomass. |
| **Extraction / fermentation** | isolate the enzyme / MAA / extract; or ferment melanin | **In:** biomass, solvent/bioreactor. **Out:** purified bio-active. |
| **Formulation** | blend bio-active into a sunscreen base or serum | **In:** bio-active, UV filters, excipients. **Out:** finished formula. |
| **SPF & stability testing** | verify SPF, photostability and enzyme activity | **In:** formula, assay. **Out:** validated product. |
| **Regulatory** | file as OTC drug (US) or cosmetic (EU/CN) | **In:** dossier. **Out:** market authorization. |
| **Retail** | pharmacy / dermatologist / DTC sale | **In:** packaged product. **Out:** consumer photoprotection. |

Cross-cutting technologies of the sector:
- **Photolyase photoreactivation (Photolyase Photoreactivation):** a blue-light-activated enzyme that monomerizes cyclobutane pyrimidine dimers caused by UVB.
- **MAA UV absorption (MAA UV Absorption):** mycosporine-like amino acids from algae/cyanobacteria absorb in the UVA range and are formulated as B2B cosmetic actives.
- **Botanical polyphenol photoprotection (Botanical Polyphenol Photoprotection):** fern and plant polyphenols (Polypodium leucotomos) quench UV-induced reactive oxygen species.

## US

The US holds the photolyase DNA-repair consumer brand, operating under the FDA's OTC-drug sunscreen monograph.

### photolyase DNA-repair enzymes
- **Neova:** a patented photolyase DNA-repair enzyme platform — DNA Repair Enzyme Serum and DNA Damage Control — that targets UV damage at the DNA level, backed by over 20 years of clinical evidence.
- **FDA OTC-drug framing:** US sunscreens are regulated as OTC drugs under the FDA monograph, so any bio-active sunscreen carries drug-level efficacy and safety obligations.

---

## CN

China's sunscreen market is dominated by mineral (zinc oxide) and chemical UV filters, with no originator of photolyase, MAA or biosynthetic-melanin actives, so the regional picture is qualitative rather than vendor-led.

### mineral/chemical SPF dominance, no bio-active originator
- **NMPA special-cosmetics registration:** sunscreens are special cosmetics requiring NMPA registration, with no distinct pathway for enzyme/MAA bio-actives.
- **No domestic bio-active originator:** the photolyase/MAA/melanin active layer is imported, not originated in China; domestic output is mineral and chemical SPF.
- **Botanical-extract adjacency:** Chinese brands add botanical extracts to SPF formulations, but none has commercialized a genuine enzyme or MAA active.

---

## EU

Europe anchors the segment, supplying both the consumer photolyase brand and the B2B MAA marine-biotech layer, under the Cosmetics Regulation.

### photolyase sunscreen, MAA B2B actives, botanical photoprotection
- **ISDIN (Spain):** Eryfotona Actinica SPF 50+ mineral sunscreen with DNA Repairomes (photolyase) — a top dermatologist-recommended bio-active sunscreen line.
- **Givaudan Active Beauty (Switzerland):** B2B marine-biotech house supplying algae-based UV / preventative anti-ageing actives (porphyrins).
- **Mibelle (Switzerland):** B2B bio-active supplier of mycosporine-like amino acids (MAAs) green-extracted from Nostoc cyanobacteria.
- **Cantabria Labs (Spain):** Heliocare 360 and ASPA-Fernblock, the Polypodium leucotomos fern-extract botanical photoprotectant (oral and topical).
- **EU Cosmetics Regulation framing:** sunscreens are cosmetics under EC 1223/2009, a lighter regime than the US OTC-drug track.

## Tech stack and innovations

The stack rests on three biological platforms: blue-light-activated DNA-repair enzymes, algal/cyanobacterial UV-absorbing amino acids, and botanical polyphenol photoprotection.

1. **Photolyase DNA-repair enzymes (Photolyase DNA-Repair Enzymes):**
   - photolyase monomerizes UV-induced cyclobutane pyrimidine dimers using blue-light energy (photoreactivation), repairing DNA damage that filters cannot prevent.
   - case: ISDIN's DNA Repairomes (Eryfotona) and Neova's patented photolyase platform, with 20+ years of clinical evidence.
2. **Mycosporine-like amino acids / MAAs (Mycosporine-Like Amino Acids):**
   - algal and cyanobacterial MAAs (e.g. from Nostoc) absorb in the UVA range and are supplied as B2B cosmetic actives.
   - case: Mibelle's green-extracted Nostoc MAAs and Givaudan Active Beauty's algae-based marine-biotech actives.
3. **Botanical polyphenol photoprotection (Botanical Polyphenol Photoprotection):**
   - fern (Polypodium leucotomos) polyphenols quench UV-induced reactive oxygen species and support skin's photoprotection.
   - case: Cantabria Labs' Fernblock in the Heliocare 360 line, oral and topical.

#### Stage 1: Bio-active sourcing
Photolyase feedstock (plankton), MAA-producing cyanobacteria (Nostoc), or fern biomass (Polypodium leucotomos) are sourced or cultured as the bio-active origin.

#### Stage 2: Extraction / fermentation
The enzyme is isolated (or melanin fermented in a bioreactor), MAAs are green-extracted from cyanobacterial biomass, or the fern extract is standardized to its polyphenol content.

#### Stage 3: Formulation
The purified bio-active is blended with mineral or chemical UV filters and excipients into a sunscreen base or a leave-on serum.

#### Stage 4: SPF & stability testing
The finished formula is tested for SPF value, photostability, and — for enzyme actives — residual enzyme activity across shelf life.

#### Stage 5: Regulatory filing
In the US the product is filed under the FDA OTC-drug sunscreen monograph; in the EU under the Cosmetics Regulation (EC 1223/2009); in China as a special cosmetic with NMPA.

#### Stage 6: Retail
The validated product reaches consumers through pharmacy, dermatologist and DTC channels — ISDIN Eryfotona and Heliocare through pharmacy/derm, Neova through retail and DTC.
