Retatrutide Skincare Routine

Rapid weight loss from retatrutide (up to 24.2% in Phase 2 trials per Jastreboff et al., NEJM 2023) places unique demands on skin. A targeted skincare routine focused on collagen support, hydration, and protection can help maintain skin quality during this transformation. This guide provides a practical, evidence-based routine for both face and body.

Morning Facial Routine

• Gentle cleanser: Avoid stripping cleansers. Use a hydrating, pH-balanced cleanser (like CeraVe Hydrating or La Roche-Posay Toleriane).
• Vitamin C serum (10-20% L-ascorbic acid): Stimulates collagen synthesis and provides antioxidant protection against UV and pollution. Apply to clean, dry skin.
• Hyaluronic acid serum: Draws moisture into skin for plumping effect. Apply to damp skin for best results.
• Moisturizer with niacinamide: Niacinamide strengthens the skin barrier, reduces inflammation, and supports collagen. Look for 5% concentration.
• Broad-spectrum SPF 30-50: Non-negotiable. UV damage is the primary accelerator of collagen breakdown. Reapply every 2 hours when outdoors.

Evening Facial Routine

• Double cleanse: Oil-based cleanser first (removes sunscreen and makeup), then water-based cleanser.
• Retinoid: The gold standard for collagen stimulation. Start with 0.025% tretinoin or OTC retinol 2-3 times per week and build to nightly use. Expect mild peeling initially.
• Peptide serum: Matrixyl or copper peptides support collagen and elastin production. Use on nights when not using retinoid if skin is sensitive.
• Rich moisturizer or facial oil: Lock in hydration overnight. Squalane oil, ceramide-rich creams, or rosehip oil are excellent options.

Body Skincare Routine

• Gentle body wash: Avoid hot water and harsh soaps that strip natural oils. Lukewarm water with a hydrating body wash.
• Body retinol lotion: Apply to areas prone to loose skin (abdomen, arms, thighs). Body-specific retinol products are formulated at appropriate concentrations for larger areas.
• Rich body moisturizer: Apply immediately after showering to damp skin. Look for ingredients like shea butter, glycerin, hyaluronic acid, and ceramides.
• Dry brushing (optional): Before showering, gentle dry brushing stimulates blood flow and may support lymphatic drainage. Use light pressure in upward strokes toward the heart.

Key Ingredients Explained

Hydration From the Inside

External skincare is only half the equation. Internal hydration is equally important: drink at least 64 oz of water daily (more if experiencing GI side effects), eat water-rich foods (cucumber, watermelon, berries), limit caffeine and alcohol (both are dehydrating), and consider collagen peptide supplementation (5-10g daily).

What to Avoid

• Excessive hot water (strips natural oils)
• Harsh scrubs or over-exfoliation
• Tanning beds and unprotected sun exposure
• Smoking and excessive alcohol
• Products with high fragrance content (can irritate and sensitize skin)

Frequently Asked Questions

When should I start a skincare routine?

Ideally before or at the same time as starting retatrutide. Prevention is more effective than trying to repair damage after significant weight loss has occurred.

Do I need expensive products?

No. Affordable brands like CeraVe, The Ordinary, and La Roche-Posay offer evidence-based formulations at accessible price points. The key is using the right active ingredients consistently, not brand prestige.

Can I use retinol and vitamin C together?

Best practice is to use vitamin C in the morning and retinol at night. While they can technically be used together, this combination may irritate sensitive skin. Alternating AM/PM avoids potential irritation.

How long before I see results from skincare?

Expect 8-12 weeks of consistent use before seeing meaningful improvements in skin texture and firmness. Sunscreen benefits are immediate (prevention), while collagen-building ingredients take time.
