@ofotherworldsskin's testosterone skin tips, fact-checked

What did @ofotherworldsskin actually say?

The creator, speaking directly to trans masc and nonbinary folks on testosterone, laid out a skincare routine for managing oiliness and acne caused by hormone therapy. Their core argument: testosterone raises sebum production, skipping moisturizer makes oiliness worse, and the right ingredients (retinol, niacinamide, salicylic acid, mandelic acid) can help you manage it without stripping your skin bare. They also name-dropped specific oils like jojoba, grapeseed, and sea buckthorn, and made the case that "balancing" oil is the goal, not eliminating it entirely. The puberty comparison they used is worth noting: "it's kind of like going through puberty almost." That's not just a metaphor. It's a mechanistic reality, and they deserve credit for framing it that way rather than catastrophizing.

Does the science back this up?

Mostly, yes, with some important caveats. The testosterone-sebum link is not in dispute. Androgens, including testosterone, bind to receptors in sebaceous glands and increase sebum secretion. A 2019 review by Agak et al. in the Journal of Investigative Dermatology confirmed that androgen signaling in sebocytes directly upregulates lipid production. This is why acne is so common during male puberty and in trans men early in hormone therapy. The "hydration prevents oil overproduction" claim is harder to pin down with rigorous clinical data, but the mechanism is plausible: dehydration can trigger a compensatory sebum response, and several dermatologists have published on this in clinical review articles (Draelos, 2006, Dermatologic Therapy). The salicylic acid recommendation is well-supported. It's a beta-hydroxy acid that is oil-soluble, meaning it can penetrate into pores rather than sitting on the skin surface, and it has documented anti-inflammatory properties (Arif, 2015, Journal of Clinical and Aesthetic Dermatology).

What did they get wrong (or right)?

The retinol claim needs some nuance. Retinoids are legitimately used for acne, but the mechanism is primarily about normalizing skin cell turnover and reducing comedone formation, not directly regulating sebum output in the way niacinamide does. Saying retinol helps "regulate the amount of oil being produced" oversimplifies the pharmacology. Niacinamide, on the other hand, does have more direct evidence for sebum regulation. A 2006 randomized controlled trial by Draelos et al. in the Journal of Cosmetic and Laser Therapy found that 2% niacinamide significantly reduced sebum excretion rate versus vehicle control. The linoleic acid point is genuinely interesting and often overlooked. Acne-prone skin tends to have sebum depleted in linoleic acid, and topical application can help normalize sebum composition (Letawe et al., 1998, Clinical and Experimental Dermatology). However, the creator said "metaphone seed oil," which appears to be a mispronunciation, likely referring to marula or perhaps meadowfoam seed oil. That's a small error but worth flagging because the wrong oil recommendation can cause breakouts in sensitive skin.

What should you actually know?

If you are on testosterone and dealing with acne, you are not alone and you are not doing something wrong. The skin changes are real, they are driven by androgen receptor activity in your sebaceous glands, and they often peak in the first one to two years of hormone therapy before stabilizing. Over-the-counter interventions like the ones in this video can genuinely help for mild to moderate cases. However, if you are dealing with cystic or nodular acne, topical skincare is not going to be sufficient. Prescription-strength options like topical adapalene (a retinoid), oral doxycycline, or in some cases isotretinoin are the standard of care for severe acne, and those require a clinician. The creator was careful not to overstate what topical products can do, and that restraint is appreciated. The clay mask caution, "don't go crazy on it," is correct. Over-drying acne-prone skin is one of the most common mistakes people make, and it tends to make things worse, not better.

The bottom line

This is one of the more accurate skincare TikToks you will find in the hormone therapy space. The creator understands sebum physiology better than most influencers and gives practical, low-harm advice. The main weaknesses are the imprecise retinol claim and the apparent mispronunciation of an oil name, which could mislead viewers looking for products. The framing around balance over elimination is genuinely good public health messaging for this community, which is often sold harsh, stripping products as a first-line intervention. If your acne is severe or not responding to the approaches described here, talk to a dermatologist or your prescribing clinician. Topical skincare has a ceiling.
