Hi, I’m Irene. Let’s make the shelf decision simpler: check the full product name first, then the steps you’ll follow back at your hotel. A familiar DHC logo alone isn’t enough to identify this bottle.
Looking for a cleansing oil that fits a shorter evening routine? DHC Deep Cleansing Oil Boost Care is worth knowing by its full name. This guide is about the Japanese-market Boost Care product, not every cleanser in the DHC range. It is a cosmetic cleanser, not a medicine.
Recognise the bottle before choosing a size

Look for ディープクレンジングオイル ブーストケア. Save this name together with the picture: it gives you a clearer reference when asking a shop assistant than “the DHC oil”.
- 150 mL: DHC announced distribution through drugstores, general supermarkets and variety stores from 9 February 2026, excluding some stores.
- 200 mL: announced for DHC’s own online/mail-order channel and directly operated stores from 5 March 2026. This is the size pictured above.
Those are the announced Japanese distribution routes, not a promise that a particular shop has stock. Check the volume before comparing shelf prices.
What does “Boost Care” mean?
DHC describes the booster function as helping subsequent skincare blend into the skin. Think of that as a cosmetic positioning, not a treatment claim or a guarantee that another product will work better. For a practical shopping decision, the useful features are simpler: wet hands are allowed, and a separate second face wash is not required.
From the bottle to a finished cleanse: three steps
The following is an editorial step guide based on DHC’s directions, not a personal-use review.
Remove the pump stopper before first use. Dispense approximately three pumps into your palm.
Work the oil into your makeup. If your skin is very wet, such as just after washing your hair, lightly remove excess water first.
Rinse with water or lukewarm water. No separate second face wash is needed.
Irene’s practical reminder: wet hands and water inside the bottle are different things. Keep water out of the container; don’t add water to it as part of the routine.
A short safety check
- Do not use on wounds, swelling, eczema or other abnormal skin.
- Stop if redness, swelling, itching, irritation, white patches or darkening occur, including after sun exposure, and consult a dermatologist.
- If it gets into your eyes, rinse immediately. Consult an eye doctor if a foreign-body sensation remains.
- Keep away from direct sun, extreme heat/humidity and children. “Low irritation” is not a guarantee against a reaction.
Your shelf-to-sink checklist
Full name → volume → steps. That is the useful takeaway: identify Boost Care, choose the size you intend to buy, and know the routine before opening the pump. If you want fewer cleansing steps, this is an option to assess against your own preferences, not a product everyone needs to replace their current cleanser with.
