OBAGI - Tretinoin 0.1%

Prescription Only — Online Medical Assessment Required

Obagi Tretinoin 0.1% Cream is a prescription-strength retinoid formulation containing tretinoin at the highest available concentration — a clinically proven vitamin A derivative and the gold standard in topical skin renewal. This strength is reserved for experienced tretinoin users who have built full tolerance to lower concentrations and are seeking maximum clinical results under prescriber guidance.

Tretinoin works by accelerating skin cell turnover, stimulating collagen production, and clearing blocked pores — addressing acne, fine lines, uneven texture, and pigmentation at a cellular level. At 0.1%, the effects are more pronounced and results typically faster, but the adjustment period requires careful management.

What It Treats

• Acne and recurring blemishes
• Established fine lines and deeper signs of skin ageing
• Stubborn uneven skin tone and post-inflammatory hyperpigmentation
• Rough skin texture and dullness
• Sun-damaged skin

Prescription-Only Formula

Obagi Tretinoin 0.1% contains tretinoin, a prescription-only medicine in the UK. You’ll need to complete a free online consultation with our UK-based clinicians before purchase. Given the potency of this concentration, our clinicians will confirm that this strength is appropriate for your skin before approving your order.

How to Use

Apply a small, pea-sized amount to clean, dry skin in the evening. Avoid the eye area, lips, and corners of the nose. Follow with a non-comedogenic moisturiser.

Always use a broad-spectrum SPF 30+ in the morning — tretinoin increases UV sensitivity and sun protection is essential throughout treatment.

Note: At 0.1%, an adjustment period of 4–8 weeks is expected. Redness, flaking, and dryness are normal during this phase. If you are new to tretinoin, we recommend starting at 0.025% and building up gradually.

Frequently Asked Questions

What is tretinoin and how does it work?

Tretinoin is a prescription-strength retinoid — a derivative of vitamin A — that works by binding to receptors in skin cells and accelerating their natural renewal cycle. This helps clear blocked pores, reduce acne lesions, stimulate collagen production, and improve the appearance of fine lines, pigmentation, and uneven texture over time.

Why do I need a prescription for tretinoin?

Tretinoin is a prescription-only medicine in the UK. Our free online consultation connects you with UK-based clinicians who will assess your skin, confirm suitability, and provide personalised usage guidance before approving your order.

Who is 0.1% tretinoin suitable for?

Tretinoin 0.1% is the highest available concentration and is intended for experienced tretinoin users who have built full tolerance to 0.025% or 0.05% over several months. It is not recommended for first-time users. If you are new to tretinoin, we recommend starting at 0.025% and progressing gradually under prescriber guidance.

What is the difference between 0.025%, 0.05%, and 0.1% tretinoin?

0.025% is the entry-level strength, typically recommended for first-time tretinoin users or those with sensitive skin. 0.05% is a mid-range concentration suitable for users who have built tolerance to lower strengths. 0.1% is the highest available concentration, delivering the most pronounced results but requiring the most careful management. Our team can advise which strength is appropriate for your skin.

What is the tretinoin purge and how long does it last?

The tretinoin purge is a temporary increase in breakouts or skin flaking that can occur during the first 4–8 weeks of treatment. It happens because tretinoin accelerates cell turnover, bringing congestion to the surface more quickly. At 0.1%, the purge may be more pronounced than at lower concentrations. It is a normal part of the adjustment process and typically resolves as the skin acclimatises.

How long does it take to see results?

At 0.1%, users with established tolerance typically begin to notice improvements in skin texture and tone within 6–8 weeks. Significant improvements in fine lines, pigmentation, and skin quality are typically visible at 3–6 months of consistent use.

Can I use tretinoin if I am pregnant or breastfeeding?

No — tretinoin is not suitable for use during pregnancy or breastfeeding. If you are pregnant, planning a pregnancy, or breastfeeding, please consult your doctor for alternative options.
