Our Science

Our Science

Built with a team of clinical professionals. Validated by trials. Made for skin that pushes back.

How we formulate

Four principles behind every Therapeautic product.

Principle 01

Clinical concentrations, not marketing concentrations

Many skincare brands include trending ingredients at fractional doses — just enough to claim them on the label. We dose every active at the concentration shown to work in clinical literature. If an ingredient can't be effective at a tolerable level, it doesn't go in.

Principle 02

We test on the skin we serve

Our trials run on people with reactive, sensitive, and atopic skin — not the average user. A formula that works on resilient skin but irritates eczema-prone skin has failed our test, regardless of what the lab data says.

Principle 03

We exclude what doesn't earn its place

Hyaluronic acid. Essential oils. Fragrance. Sulphates. Each is widely used; each carries real cost for reactive skin. We've published our reasoning for every exclusion in the Journal — not as marketing, but so customers can audit our choices.

Principle 04

Hong Kong climate, every formulation decision

Our formulas are developed for the reality of subtropical heat, humidity swings, and air-conditioned interiors. Ingredients that perform in dry European climates can backfire here. We test in the conditions our customers actually live in.

What customers say

Real reviews from people who tried, tested, and stayed.
"Love the face cream and serum much. It moisturises my sensitive skin without any burden on my face"
"My skin feels really good after using this cream. I would recommend it to people with dry skin. It has a light scent which is pleasant."
“The texture of this face cream is pretty refreshing, not greasy at all. I only applied a very small amount of cream and was moisturising enough which lasted for the whole night. But what amazed me is the cream working wonders for the psoriasis on my elbows! It makes my elbows soft and smoother the next morning. I have tried many products before, so I know when I’m using the right one.”
"The botanical infusion in the night serum has completely transformed my texture. I woke up with skin that finally felt calm and hydrated."
Hydrating moisturizer that doesn’t cause pilling even in the summer,It works very well for soothing red and inflamed patches - skin calms down overnight.
“Highly recommend it! I have allergic rhinitis, so I will rub my nose all the time. Therefore my skin around the nose is always dry and peeling, but this situation is gone after I apply a small amount before I go to bed every night. And I will put some on as the last step of my night skincare routine if my skin is unstable, it will be glowy, plump and radiant the next morning when I wake up! It’s not just a skin saver but a life saver!”
"The cream is good for inflammation .My face was quite inflamed but not since I started using it."
