A Ret Gel 0.1% (20 g)

A Ret Gel 0.1% (20 g) is a prescription topical tretinoin gel used on the skin to help treat acne. Each 20 g tube contains tretinoin 0.1%, which is the highest-strength A Ret Gel we carry. Tretinoin is a retinoid, a vitamin A–derived medicine that helps unclog pores and improve acne-related breakouts and skin texture over time.

How it works: Tretinoin speeds up skin cell turnover, which helps prevent dead skin cells from clogging pores and forming new acne lesions. In gel form, A Ret Gel 0.1% (20 g) spreads easily over the skin and delivers tretinoin directly where acne is forming.

A Ret Gel 0.1% (20 g) is the strongest version in this brand range, with 0.1% tretinoin per tube compared with A Ret Gel 0.05% (20 g) and A Ret Gel 0.025% (20 g). Because it is a higher-strength gel, it is usually chosen for people who need more intensive acne treatment and can tolerate a stronger level of skin irritation than lower strengths. A doctor may select A Ret Gel 0.1% (20 g) when lower strengths have not worked well enough or when a stronger prescription is appropriate.

• Acne vulgaris
• Comedones, blackheads, and whiteheads
• Acne-prone oily skin
• Help prevent new clogged pores
• Improve skin texture over time

• Use only on clean, completely dry skin at night unless your prescriber tells you otherwise.
• Apply a pea-sized amount in a thin layer over the affected area, not just on individual pimples.
• Avoid the eyes, eyelids, lips, corners of the nose, and broken or sunburned skin.
• Wash your hands after applying the gel.
• Do not use more often or in a thicker layer to try to make it work faster.
• Use sunscreen and limit sun exposure while using tretinoin gel.

A Ret Gel 0.1% (20 g) provides tretinoin at 0.1% strength in each tube, which is a high-strength topical dose. It is usually applied once daily at night, but your doctor may tell you to start less often if your skin is sensitive. Do not apply more than directed; your prescriber decides the frequency and duration based on your skin response.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Tretinoin may include:

• Skin dryness
• Redness
• Peeling or flaking
• Burning or stinging sensation
• Itching
• Increased skin sensitivity to sun, which may be more noticeable with this 0.1% strength

• A Ret Gel 0.1% (20 g) is the highest-strength A Ret Gel we sell, so irritation is more likely than with 0.025% or 0.05%.
• Do not use on eczema, cuts, sunburn, or very irritated skin unless your clinician says it is okay.
• Avoid excessive sun, tanning beds, and harsh weather exposure; use sunscreen daily.
• Do not combine with other irritating acne products, such as scrubs, alcohol-based toners, or strong exfoliants, unless your doctor approves.
• Use caution if you are pregnant, trying to become pregnant, or breastfeeding; ask your clinician for guidance before use.
• Do not apply immediately after shaving, waxing, or other skin procedures if the skin is already sensitive.
• This gel is for external use only and should not be taken by mouth.

• Other topical retinoids or retinoid-containing products
• Benzoyl peroxide, salicylic acid, sulfur, or resorcinol products that may increase irritation
• Abrasive soaps, scrubs, and peeling agents
• Topical corticosteroids unless your prescriber instructs you to use both
