The Brazilian dermatologist channel: how Theraskin and ADCOS built skincare Brazilians actually use

The dermatologist-channel reality

Brazil has 35,000 dermatologists. That's the third-highest dermatologist density per capita in the world, behind only Greece and Italy. And Brazilian dermatologist visits aren't reserved for medical issues — preventive skincare consultations are routine, covered by both private and supplementary insurance, and culturally treated as normal maintenance rather than vanity.

This creates an unusual market structure. The serious skincare brands in Brazil don't compete for shelf space at Sephora or Beleza Na Web. They compete for the dermatologist's recommendation slip — a small physical or digital prescription that the dermatologist hands the patient at the end of the consultation, listing specific products and brand names.

Theraskin and ADCOS own this channel. Ada Tina competes hard for it. Principia is increasingly accepted in dermatology channels. And the formulations these brands ship reflect dermatologist preferences entirely — not consumer preferences, not influencer trends, not international beauty-press writeups.

Theraskin: the São Paulo dermatology workhorse

Theraskin is owned by Theramex (a Brazilian pharma group) and was founded specifically to supply the São Paulo dermatology channel. The brand doesn't run consumer marketing in any meaningful sense. Theraskin's customer is the dermatologist; the patient is the dermatologist's customer. This three-party model shapes everything about the line.

The Acnase Gel Secativo is the brand's bestselling product — a salicylic acid spot treatment dispensed at virtually every São Paulo acne consultation. The formulation is unsexy, the packaging is medical-functional, and the price (~R$45) is calibrated for daily-use acne patients without insurance subsidies. The product works because Brazilian dermatologists trialled it on their own patients and kept reordering.

The Acnase Tônico Adstringente plays the morning oil-control role in the dermatology-prescribed acne protocol. The Euryale C Vitamin C Serum covers the brightening half. The HA Concentrate handles barrier support after acne treatment. Each product is positioned as a step in the dermatologist-prescribed protocol rather than a standalone hero.

This protocol-thinking is what consumer brands like Sallve and Principia are now copying. But Theraskin had it first because the dermatology channel demanded it.

ADCOS: the Brazilian dermo-cosmetic powerhouse

ADCOS is structurally bigger than Theraskin and operates across a wider product range. The brand was founded in São Paulo in 1999 specifically as a Brazilian alternative to imported French dermo-cosmetic brands (Avène, La Roche-Posay, Bioderma) — formulations designed for Brazilian skin and Brazilian climate, distributed through Brazilian dermatology offices.

The Mela-Off line is ADCOS's most clinically-positioned product family. Tranexamic acid pads designed for melasma and post-inflammatory hyperpigmentation — both of which affect Brazilian Fitzpatrick III-V skin at higher rates than the populations most international brands formulate for. The Mela-Off Whitening Serum extends the protocol into a serum format.

ADCOS's sun protection range is where the brand competes hardest with French and Spanish imports. The Filtro Solar Tonalizante FPS 60 Pele Madura is a tinted SPF60 formulated for mature skin in tropical climates — a niche that Heliocare and ISDIN both compete for, but ADCOS owns at the Brazilian price point. The Mousse Mineral FPS50 is a mineral mousse format that works under makeup in 35°C+ humidity. The Protetor Solar Stick FPS80 brings SPF80 into stick format.

The Renove Retinol Multifuncional 0.5 and Sérum Vitamina C 20 round out the active treatment line. Across the range, ADCOS prices below imported dermo-cosmetic brands while delivering equivalent clinical performance.

What dermatologists actually prescribe

Walk into a São Paulo dermatology office in 2026 with combination skin and visible acne marks, and the prescription slip looks something like this:

Morning:

• Theraskin Acnase Tônico Adstringente (oil control)
• Theraskin Euryale C or ADCOS Sérum Vitamina C 20 (vitamin C)
• ADCOS Filtro Solar Tonalizante (SPF + tint)

Evening:

• Cleanser (often dermatologist's clinic brand)
• Theraskin Acnase Gel Secativo on active spots
• ADCOS Mela-Off Pads on PIH-prone areas
• Theraskin HA Concentrate (barrier support)

This isn't a marketing pitch. It's a real prescription protocol that thousands of Brazilian dermatologists prescribe weekly, with minor variations.

Where Sallve and Principia fit

Sallve — Julia Petit's DTC brand — sells extraordinarily well at the consumer level but has lower penetration in the dermatologist channel. Sallve's positioning is influencer-led and DTC-priced; dermatologists prefer brands with longer clinical histories and tighter pharmacy distribution.

Principia bridges the gap. The brand pitches consciously to both consumer and clinical channels — its formulations have ingredient-list rigor that satisfies dermatologist scrutiny, and its packaging has enough cosmetic appeal to drive consumer purchases. The Principia Skincare Niacinamide 10% is the bridge product — accepted by dermatologists, popular with consumers.

Ada Tina plays a niche role with its Depore Tonic and pore-targeted formulations — a smaller brand with stronger penetration in specific clinical niches.

The export question

Brazilian dermatology brands are starting to export. Theraskin ships to Portugal and select EU markets. ADCOS sells in Latin America and increasingly in Florida. Sallve has limited US distribution. But the export economics struggle: these brands were built for the Brazilian price-to-performance ratio, and translating that economics to higher-cost markets without losing the brand identity is the challenge that Sephora-distributed Brazilian brands like Sol de Janeiro solved by going cosmetic-aspirational rather than dermo-clinical.

For now, the best place to access serious Brazilian skincare remains São Paulo or Rio. The pharmacy and dermatology channels there carry the full range that international markets only see in fragments. And the formulations are still calibrated for the Brazilian face that wears them daily — humidity, UV, melanin, and all.
