Snake venom serum with retinol: separating peptide fact from TikTok fiction

What did @heniekasetiawati actually say?

The transcript here is heavily garbled, likely a transcription artifact from an Indonesian-language video. Based on the caption and hashtags, the creator is promoting a product called Seraphic Synake Serum, describing it as "the first serum in Indonesia" with snake venom and retinol, and backing that pitch with a money-back guarantee. The phrase "bisa ular" translates directly to snake venom. The creator also appears to reference "Dr. Green" as some kind of authority, though what that means in context is unclear. What we can work with is the product claim itself: that a serum containing snake venom-derived ingredients does something meaningful for skin, and that the combination with retinol makes it worth trying. Let's take that at face value and see how it holds up.

Does the science back this up?

Partially, but with serious asterisks. Synake is not actual snake venom. It is a synthetic tripeptide called diaminobutyroyl benzylamide diacetate, designed to mimic the activity of a compound found in Temple Viper venom. That compound, waglerin-1, acts on acetylcholine receptors at the neuromuscular junction. The theory is that blocking muscle contractions at the skin surface reduces the appearance of expression lines. One industry-funded study (Blanes-Mira et al., 2002, International Journal of Cosmetic Science) showed some acetylcholine receptor binding activity in lab conditions. That is a long way from clinical proof. Independent, peer-reviewed human trials on Synake specifically are thin. The retinol component is more defensible: retinol's effect on collagen synthesis and skin cell turnover is one of the better-supported claims in topical skincare (Mukherjee et al., 2006, Clinical Interventions in Aging). The combination is not inherently dangerous, but calling the synake component transformative is getting ahead of the evidence.

What did they get wrong (or right)?

The "snake venom" framing is technically misleading. Synake is a synthetic peptide analog, not extracted venom. Marketing it as "bisa ular" (snake venom) is a classic cosmetic industry move that leans on the shock value of the word venom to imply dramatic effect. Consumers deserve to know the difference between a synthetic mimic and an actual biological extract. That said, the creator does get something right by pairing the ingredient with retinol. Retinol has decades of human trial data behind it (Kafi et al., 2007, Archives of Dermatology). If the formulation has a meaningful retinol concentration, that alone could produce visible results, which may then get attributed to the synake. The money-back guarantee framing is a marketing device, not a scientific claim, so it does not deserve a pass as evidence of efficacy.

What should you actually know?

If you are considering a serum like this, here is what the evidence actually supports. Synake as a peptide ingredient has plausible biochemical logic behind it, but lacks the independent clinical trial depth that retinol, niacinamide, or vitamin C have accumulated. It is not dangerous at cosmetic concentrations, but it is not proven either. Retinol, on the other hand, has a legitimate track record. Any benefit you notice from a combined serum is more likely coming from the retinol. One more thing worth flagging: products marketed with phrases like "first in Indonesia" and "money-back guarantee" are using commercial language, not clinical language. Neither claim tells you anything about how the product performs on your skin. If you have reactive skin, note that retinol can cause irritation, purging, and photosensitivity, particularly at higher concentrations. Start low, use sunscreen, and do not let the venom branding make you skip the basics.
